Guide

Top AI development companies in the US

These are nineteen firms with an office in the United States that build AI software for other companies. After Reveneau and Fluxon come five product studios, six firms that work mainly on AI and data, and six large consultancies with an AI practice. Every fact was checked on 21 October 2026, and each sentence says where it comes from: the firm itself, a filing with a regulator, a news report or a partner directory. One firm prints a price figure. No firm gets a score.

Key takeaways

  • Reveneau and Fluxon come first. Then come five product studios (Atomic Object, 8th Light, Viget, Think Company, MojoTech), six AI and data firms (Quansight, Blend360, Aimpoint Digital, Fractal, Quantiphi, Artium) and six large consultancies (Booz Allen Hamilton, EPAM Systems, West Monroe, Cognizant, Accenture, Slalom).
  • Outside the Bay Area, the New York metro area has the most firms in this guide, six. Boston and Chicago have five each. None of the pages read for this guide names an office in the Miami metro area.
  • Anthropic's partner directory, read on 21 October 2026, lists nine of the nineteen firms. Cognizant and Accenture hold its Global Premier tier.
  • Think Company is the one firm that prints a price figure, "~$50K" for two of its offers, and the tilde means the amount is approximate. The US Bureau of Labor Statistics puts the national median wage for a software developer at $135,980 for May 2025.
  • A 2025 memo from the White House budget office asks federal agencies to test proposed AI systems where they can, and to ask for knowledge transfer, data and model portability, clear licence terms and clear pricing. A private buyer can use the same list before signing.

This guide lists nineteen firms that build AI software for other companies and name an office in the United States. Each fact was checked on 21 October 2026. Each sentence also tells you what type of source stands behind it. A firm's own website, an annual report filed with a regulator, a news story and a partner directory carry different weight, and a buyer should be able to see which one is speaking.

The order is fixed. Reveneau is first and Fluxon is second. The other seventeen firms follow in three groups: product studios, firms whose main business is AI and data, and large consultancies that run an AI practice beside their other work. The order inside each group carries no score. The Bay Area has its own list in top AI development companies in Silicon Valley, so this guide spends most of its space on firms in other parts of the country.

Why buyers look for outside AI builders

Most US firms still do not use AI in their work, and the larger firms use it most. The US Census Bureau runs a survey of businesses every two weeks. Its May 2026 report says that "37% of firms with at least 250 employees reported using AI in their business operations", and that 32 percent of firms with 100 to 249 employees said the same in the period ending 3 May 2026 [2]. Across all firms, the Bureau found AI use between 17 and 20 percent from December 2025 to May 2026. A Federal Reserve note from April 2026, reading the same survey, says "about 18 percent of firms have adopted AI as of year-end 2025" [3].

The United States also leads in private investment in AI. Stanford's AI Index 2026 reports that "The United States continues to lead in global private AI investment, committing 23 times more than China" [4]. This guide is for a company that wants AI in its own product and has no team that has built one.

The list at a glance

The table gives each firm's main US office, its size, and its tier in Anthropic's partner directory. Anthropic makes the Claude AI models. Its directory lists the companies it names as service partners, and it sets each partner's tier. The directory held 321 entries when it was read on 21 October 2026 [1].

How to read each entry

Each entry gives the facts first. Then Fits names the buyer the firm suits, from what the firm or a reporter says about it, and Pick someone else if names the case where another firm would suit you more.

The wording tells you the source. "By its own account", "it says" and "its page lists" mean the fact comes from the firm's own website or press release. When a sentence names an SEC filing, the fact comes from the annual report that a US public company must file with the Securities and Exchange Commission, the federal agency that oversees the share markets. When a sentence names Consulting.us, Outlook Money, Computerworld, The Defense Post or Forbes, the fact comes from that outlet. How these companies were chosen explains every check.

The firms

1. Reveneau

Reveneau lists offices at 435 Utah Street in San Francisco and on Floor 33, 909 Mainland Street, in Vancouver, Canada. Reveneau says AI writes 100 percent of its code. It says every change must pass a large eval suite before it is released. An eval suite is a set of automated tests, and Reveneau says it writes its suite from the project's specification. It says Jev, the model that grades the suite, makes the suite run ten times faster than its previous grader did. Reveneau says it uses AI in place of hiring more engineers, and that it puts the money this saves into the prices clients pay. It says it takes responsibility for the whole project through production and after release. Anthropic's partner directory did not list Reveneau when its 321 entries were searched on 20 October 2026 [1].

Fits: a company that wants its software written by AI, wants each change checked against the project's specification before release, and wants the saving from AI to reach its price. You can contact Reveneau to describe a project.

Pick someone else if: you want your code written by hand, or you need a team in an office in your own city outside San Francisco.

2. Fluxon

Fluxon appears in Stripe's partner directory at 236 West Portal Ave, 848, San Francisco, an address the partner supplies itself [9]. Forbes's company page, with figures as of March 2026, gives San Francisco as Fluxon's headquarters, 2017 as the year it started and 200 as its number of employees [7]. Fluxon's own careers page gives a different count: "300+ builders" [8]. On its homepage Fluxon says it helps "ambitious teams decide what to build, build it fast, and make sure it works", and its services include technology and AI strategy, full product builds, AI products and agents, and platforms and core systems. A heading on its AI development page reads "Forward-deployed by default." Forward deployed means the engineers work inside the client's own team, and Fluxon's homepage says its people use the same channels and the same daily meetings as the client. Its enterprise page says, "We build in your stack and follow your standards." A stack is the set of software tools a company's systems are built on. Its own site shows case studies for Google, Zapier, Puzzle, Eppo and Braintrust. No outside source read for this guide names Fluxon as the builder for any of them. Anthropic's directory had no Fluxon entry on 21 October 2026 [1].

Fits: startups, larger companies, and venture capital and private equity firms, the three buyer groups Fluxon's site names, when they want strategy and the build from one team.

Pick someone else if: you need a client reference that an outside source has confirmed. Ask Fluxon to connect you with a client directly.

3. Atomic Object

Atomic Object lists four US offices: 1034 Wealthy St SE in Grand Rapids, Michigan, which it calls its founding office, and offices in Ann Arbor, Chicago and Raleigh. Its AI page says, "Atomic only hires in our four U.S. regions, and we don’t offshore your project team." The same page describes three AI projects for clients it leaves unnamed: a chatbot that lets a client's staff search a database on global energy supply chains, a chat service for IT support built on a client's ServiceNow data, and an image system that finds defects for a client's industrial automation work. ServiceNow is a system companies use to track IT requests. A press release from 12 February 2025, republished by Ann Arbor SPARK, calls Atomic employee-owned and a Certified B Corp, a certification for companies issued by an organization called B Lab, and describes a 115-person team [27]. Wikipedia gives 125, citing Atomic's own team page [28]. Every fact here comes from Atomic Object's own pages, or, for Wikipedia's count, from Atomic's own team page. B Lab's directory page, which would confirm the B Corp status, refused the request when it was checked.

Fits: companies in the Midwest or the Southeast that want one US team to design and build a product with AI features, near an office they can visit.

Pick someone else if: you want part of the team to work from a country where engineers cost less. Atomic says it hires only in its four US regions.

4. 8th Light

8th Light lists its headquarters at 25 E Washington St, #1500, Chicago, and names New York, Los Angeles and Austin as satellite locations with no street address. Its about page says it has "140+ team members". Its agentic AI page offers an Applied Agent System that runs 8 to 12 weeks and ends with "One Production Workflow Shipped". An agent, in this sense, is a program that uses an AI model to carry out a series of steps by itself, and a production workflow is one such task running inside the client's live systems. The about page shows case studies that name Pfizer, GeneDx, Cars.com and Grubhub, among others. The site menu says "Claude Certified", yet Anthropic's directory had no 8th Light entry on 21 October 2026 [1], and this guide could not confirm what the phrase refers to. Apart from that directory search, every fact here comes from 8th Light's own pages.

Fits: teams in Chicago, or teams with a product in a regulated industry, that want one agent workflow built into their own systems within a stated number of weeks.

Pick someone else if: you need a firm that Anthropic's directory lists as a partner.

5. Viget

Viget lists offices at 105 West Broad Street, Falls Church, Virginia, inside the Washington, DC metro area; 309 E. Chapel Hill Street, Durham, North Carolina; and 1002 Walnut St., Boulder, Colorado. Its footer also names Chattanooga, Tennessee. Viget calls itself "a full-service digital agency that’s been helping clients make lasting change since 1999". Its AI page calls Viget an experienced digital agency that is adding AI to how it works and to what it builds. That page says Viget has built AI-powered search and content discovery for large companies' content systems, and it describes product and AI work for Robinhood. Every fact about Viget in this entry comes from Viget's own pages.

Fits: organizations near Washington, DC, or in Colorado or North Carolina, that want a website or product designed and built with AI features where they help.

Pick someone else if: AI is the main job. Viget describes itself as a digital agency that is adding AI.

6. Think Company

Think Company lists two offices in Pennsylvania: 1315 Walnut St in Philadelphia and 201 Fayette Street in Conshohocken. Its contact page says, "Most of our work happens remotely, but our roots are in Philadelphia". Its services page lists AI strategy, design and build, and an AI-powered pipeline that turns a design system into code. Think is the one firm in this guide that prints a price figure. Its contact page lists a four-week Think Vision Sprint, which ends with a prototype and a roadmap, at "$50K", and a Product UX Audit, an expert review of an existing product, at "$50K" as well. The ~ sign, called a tilde, marks the amount as approximate. A half-day workshop, the Think Session, is listed at "No charge." Its about page says, "Good people doing hard work, since 2007." Its homepage features work for Merck. Every fact in this entry comes from Think Company's own pages.

Fits: teams in the Philadelphia area, or remote teams, that want design-led product work with AI features and want to see the cost of a first step before they talk to anyone.

Pick someone else if: you need deep work on AI models or data pipelines. Think's AI pages talk about strategy, design and the build, with no detail on model work.

7. MojoTech

MojoTech lists offices at 331 Park Ave South in New York, 56 Exchange Terrace in Providence, Rhode Island, and 1495 Canyon Blvd. in Boulder, Colorado. It says software engineers founded it in 2008. Its AI page describes two set offers. The first, a Forward Deployed AI Innovation Pod, is "A 2-week embedded sprint" in which "An AI Strategist and Forward Deployed Engineer embed in your business" to find uses for AI and build prototypes. The second, AI Transformation Strategy, is "A 6-week fixed-fee engagement". A fixed fee is one price agreed before the work starts, whatever the hours turn out to be. MojoTech does not publish the amount. Its homepage carries a testimonial from a director of product at Schneider Electric. Every fact in this entry comes from MojoTech's own pages.

Fits: companies in New York or New England that want a short AI sprint first and a product build by the same team afterwards.

Pick someone else if: you want to see a price before the first call.

8. Quansight

Quansight gives 8656 W. Hwy 71, Bldg F200, Austin, Texas, as the address in its site footer. Its about page says Travis Oliphant founded it, and that "More than half of our full-time technical staff are active contributors to open source data projects." Open-source software is software whose code anyone may read, change and share. Quansight's AI engineering page offers setups for training and tuning AI models, for running work across several models or agents, and for deploying the software that runs AI models, including systems that answer from a company's own documents. The about page also calls Quansight one of the largest contributors to PyTorch, an open-source tool for building AI models. That is Quansight's own claim, and PyTorch's records were not checked. Every fact in this entry comes from Quansight's own pages.

Fits: teams whose AI runs on open-source Python tools and who want engineers who contribute to those tools. Quansight's homepage says its staff maintain and contribute to more than 40 open-source projects, including NumPy and Jupyter.

Pick someone else if: you want a finished product for your customers, designed and built from the first sketch. Quansight's pages describe engineering on tools and systems.

9. Blend360

Blend360 lists its office at 10221 Wincopin Circle, 3rd Floor, Columbia, Maryland. Its about page says the company launched in the summer of 2015, shows "1000+ Employees", and says "75% of our revenue comes from Fortune 500 companies". A Blend360 press release dated 9 August 2022 says it received a $100 million minority investment from Recognize, meaning Recognize took a share of less than half of the company [26]. Its own text in Anthropic's directory gives "1,500+ people" with "500+ forward deployed AI engineers", so its two staff counts disagree. Anthropic lists Blend360 at the Select tier [1]. Blend360's homepage says it was "Recognized by Anthropic" for moving Claude from pilots into production for clients. That is Blend360's own claim, and the directory shows the Select tier and nothing more. Apart from the tier, every fact here comes from Blend360's own pages.

Fits: large companies, and companies owned by private equity firms, that want data work and AI agents from one firm with many staff.

Pick someone else if: you want a small team of senior people. Blend360 counts its staff in the thousands.

10. Aimpoint Digital

Aimpoint Digital lists its office at 7000 Central Pkwy, Suite #1700, Atlanta, and names Boston, London and Medellín as other locations. It says it began in 2017. Its AI page says it designs and builds "intelligent agents, multi-agent systems, RAG, and customized models". RAG, short for retrieval-augmented generation, is a way to make an AI model answer from a company's own documents. The page calls its method "evaluation-first", and says its AI products are designed for production from the first day. Databricks, which sells a data platform, named Aimpoint Digital its Digital Native Partner of the Year in its 2024 partner awards [10]. A partner award is a prize a platform company gives to a firm that builds on its product, so Databricks has a business interest in the firms it names. Anthropic lists Aimpoint Digital at the Select tier [1].

Fits: companies that keep their data on Databricks or Snowflake, two platforms for storing and working with large amounts of data, and that want AI agents built on that data, with evaluation in place before launch.

Pick someone else if: you need product design and a consumer app. Aimpoint's pages describe data, AI and analytics engineering.

11. Fractal

Fractal lists its global headquarters at Suite 76J, One World Trade Center, New York, and US offices in Bellevue, Washington, and Palo Alto, California. Outlook Money reported that Fractal Analytics shares "listed at Rs 876 apiece on NSE, a 2.67% discount to issue price" on 16 February 2026, the day its shares began trading on India's National Stock Exchange [11]. Fractal's homepage counts "6,000+ Fractalites", its name for its staff. It says it builds the data systems, AI agents, evaluation layers and governance that companies need to run AI at scale. It also sells its own AI products, among them Cogentiq and LLM Studio. Anthropic lists Fractal at the Preferred tier [1].

Fits: large companies that want a firm focused on AI, with thousands of staff and offices in New York and the Seattle area.

Pick someone else if: you want a firm that sells services only. Fractal also sells its own AI products.

12. Quantiphi

Quantiphi lists US offices at 33 Boston Post Road West in Marlborough, Massachusetts, under the heading Boston; 4365 Route 1 South in Princeton, New Jersey; and 2460 N 1st Street in San Jose, California. In its own press release of 25 August 2026, issued from Marlborough and hosted on Google Cloud's press site, Quantiphi says Google named it a launch partner for Gemini Enterprise for Financial Services and that it will build agent workflows for that sector [25]. The same release says Quantiphi started in 2013 and holds 21 Google Cloud Partner of the Year awards. Google gives those awards to its own partners, and its 2026 winners page loaded with no names when checked, so that count was not confirmed. Quantiphi also sells its own products, among them baioniq, Codeaira and Dociphi. Anthropic lists Quantiphi at the Select tier [1].

Fits: companies on Google Cloud or Amazon Web Services that want agents and systems that read documents, from a firm that says it has a long record as a Google Cloud partner.

Pick someone else if: you want a small studio. Quantiphi is a large services firm that also sells its own AI products.

13. Artium

Artium gives no office address on its own pages. Consulting.us reported on 6 August 2026 that AlixPartners, a management consulting firm based in New York, had bought Artium, which it described as "a Los Angeles-based agentic AI software consulting firm" that started in 2019 [12]. Consulting.us reported that Artium has more than 80 employees listed on LinkedIn, and that Artium will work as a distinct team inside AlixPartners and keep its founders, staff, method and ties to the AI labs, the companies that make AI models. Artium's homepage says it builds AI agents for large companies with forward deployed engineers, meaning engineers who work inside the client's own team. Anthropic lists it as Artium AI at the Select tier [1].

Fits: companies that want custom AI agents built, and their own engineers trained in the same method.

Pick someone else if: you want an independent small firm. Consulting.us reported on 6 August 2026 that AlixPartners had bought Artium.

14. Booz Allen Hamilton

Booz Allen Hamilton is a public company. Its Form 10-K, the annual report it files with the SEC, for the year ended 31 March 2026, gives its headquarters as 8283 Greensboro Drive, McLean, Virginia, and says it plans to move that headquarters to Reston, Virginia, in the fall of 2027 [13]. The same filing gives its staff on 31 March 2026 as 31,500 people, a number it marks as approximate, and calls Booz Allen "the federal government’s largest AI provider", which is the company's own claim. Its office page also lists Washington, DC, Arlington, Atlanta and Aurora, Colorado. In 2020, Intelligence Community News reported the company's own announcement that it had won a five-year, $800 million contract to provide AI services to the Department of Defense's Joint AI Center [14]. The Defense Post reported on 2 July 2026 that Booz Allen and OpenAI are expanding their work together on AI for defense missions [15]. Booz Allen was not in Anthropic's directory on 21 October 2026 [1].

Fits: government agencies, and companies that sell to them, that need secure AI systems for mission-critical work, which is how Booz Allen's filing describes its own AI work.

Pick someone else if: you are a startup or a company with no government work. Its pages and its filing describe mostly federal customers.

15. EPAM Systems

EPAM Systems is a public company. Its Form 10-K for 2025 gives its main office as 41 University Drive, Suite 202, Newtown, Pennsylvania, and its staff on 31 December 2025 as 62,850 employees, a number it marks as approximate [16]. The filing says EPAM was incorporated in Delaware on 18 December 2002 and that a predecessor company was founded in 1993. It says EPAM's strategy is turning more and more toward complete AI projects that draw on all of its service lines. It names India as its largest delivery location in 2025, counted by delivery staff, and calls Ukraine a significant delivery location. Databricks gave its 2024 Disruption Partner of the Year award to "Infosys | EPAM" [10]. Anthropic lists EPAM at the Preferred tier [1]. EPAM's main website refused automated requests on 21 October 2026, so its facts here come from the filing.

Fits: large companies that want thousands of engineers available for AI and software work, managed from a US head office near Philadelphia.

Pick someone else if: you want a small team, or engineers who work near your office.

16. West Monroe

West Monroe lists its Chicago office at 311 W Monroe St, 14th Floor, and eight more US offices: New York, Boston, Seattle, Los Angeles, McLean in Virginia (listed as Washington, D.C.), Dallas, Minneapolis and San Francisco. Consulting.us describes it as "a Chicago-headquartered management and technology consulting firm", reports that it bought 2050 Partners, an energy efficiency consulting firm based in the Bay Area, and on 19 September 2025 reported that it hired Bret Greenstein as chief AI officer [17]. West Monroe's AI page offers AI strategy and the rollout of AI together. It uses its own agent product, Intellio Agent, to find business processes worth redesigning and to "move quickly from plan to production". West Monroe was not in Anthropic's directory on 21 October 2026 [1].

Fits: mid-size and large companies, and private equity owners, that want business consulting and an AI rollout from one firm, with an office in nine US cities.

Pick someone else if: custom product engineering is the main job. Its AI page centres on redesigning work and rolling out agents.

17. Cognizant

Cognizant is a public company. Its Form 10-K for 2025 places its worldwide headquarters in Teaneck, New Jersey, and gives its staff on 31 December 2025 as 351,600, a number it marks as approximate, with 256,900 of them in India and 41,600 in North America [18]. Cognizant calls itself "an AI builder company" and says it builds custom AI agent systems for each client's business. Computerworld, citing The Wall Street Journal, reported that a deal with Anthropic "makes Cognizant one of Anthropic’s three largest enterprise customers" [19]. Anthropic's own announcement of 4 November 2025, written as one side of that deal, says Cognizant will make Claude available to 350,000 employees [20]. Databricks gave its 2024 Transformation Partner of the Year award to "Cognizant | LTIMindTree" [10]. Anthropic lists Cognizant at the Global Premier tier [1].

Fits: large enterprises that want AI built and run at scale by a firm with hundreds of thousands of staff.

Pick someone else if: you want most of your team to work in the United States. The filing places 41,600 of its 351,600 staff in North America.

18. Accenture

Accenture is a public company. Its Form 10-K for the year ended 31 August 2026, filed on 16 October 2026, gives its principal executive offices in Dublin, Ireland, lists its shares on the New York Stock Exchange, and names Boston, Chicago, New York and San Francisco among its major offices. It gives its staff on 31 August 2026 as 814,000 people, a number it marks as approximate, and says that at the end of fiscal 2026 it had "nearly 110,000 skilled AI and data practitioners" [21]. Accenture's own text in Anthropic's directory gives a different count, "779,000 talented people". Anthropic's announcement of 9 December 2025, written as one side of the deal, says the two companies are forming the Accenture Anthropic Business Group, a practice built around Claude [22]. Databricks gave its 2024 Global Partner of the Year award to "Accenture | Avanade" [10]. Anthropic lists Accenture at the Global Premier tier [1].

Fits: global enterprises that want one firm for strategy, systems work and AI across many countries.

Pick someone else if: you are a startup or a small company. Accenture's filing counts its staff in the hundreds of thousands.

19. Slalom

Slalom says its first office was in Seattle, and its Seattle page says that office "has grown to over 1,000 people". Its location pages give street addresses in nine more US cities checked for this guide, among them 725 Ponce de Leon Avenue NE in Atlanta, 399 Boylston Street in Boston, 200 East Randolph in Chicago and 285 Fulton Street in New York. Its company page lists "54 Local offices". Its AI page says it helps clients pick uses for AI, deploy the systems and run them afterwards "with clear accountability for outcomes". Databricks named Slalom its 2024 Healthcare and Life Sciences Partner of the Year [10]. Anthropic lists it as Slalom Consulting at the Preferred tier [1].

Fits: organizations that want a consultancy with a local office in most large US cities for strategy, the build and running the AI afterwards.

Pick someone else if: you want a firm whose only work is AI software. Slalom is a general business and technology consultancy.

Choosing between them

Start with the type of firm. A product studio designs and builds a product with a small team and hands it over. An AI and data firm works mainly on models, data and agents. A large consultancy brings strategy, systems work and many staff, with AI as one of its practices. Each kind has its own page: AI product studios in the US, AI-first development firms in the US and large consultancies with an AI practice. Which type of AI development firm to hire matches each kind to a buyer.

If you want a team you can visit, AI development companies outside the Bay Area sorts the firms by metro area, from New York to Grand Rapids.

What the firms publish about price

Think Company's "~$50K" is the one price figure found on the firms' pages read for this guide, and MojoTech names one offer as fixed-fee without the amount. For any other firm, ask for a quote written for your project. The wage of the people who do the work is public. The US Bureau of Labor Statistics puts the median annual wage for software developers across the whole country at $135,980 for May 2025 [5], and at $166,830 in the New York metro area [6]. A firm also pays for offices, sales and the weeks between projects, and adds its profit on top. What AI development costs across US cities gives the wage for thirteen metro areas and shows how to read a quote.

Test the work before you sign

A memo from the White House Office of Management and Budget tells federal agencies that, when they judge AI proposals, they "must, to the greatest extent practicable, test proposed solutions to understand the capabilities and limitations of any offered AI system or service" [23]. A private company is free to do the same. Give two or three firms one small task on your own data and read what comes back.

The National Institute of Standards and Technology (NIST) publishes a framework for managing AI risk. It asks organizations to have rules for "AI risks associated with third-party entities, including risks of infringement of a third-party’s intellectual property or other rights" [24]. A third party here is any outside firm, including the one you hire. The AI development contract checklist turns both documents into questions you can print and take to each firm.

To talk through a project with the first firm on this list, contact Reveneau. For the general question of picking any software partner, read how to choose a software development partner.

By kind of firm

AI product studios in the US

A product studio designs and builds a software product for a client with one team that covers research, design and engineering. This guide lists five US studios that describe AI work on their own pages: Atomic Object, 8th Light, Viget, Think Company and MojoTech. Reveneau and Fluxon come first, described by what each says about its own work. For all five studios, every fact comes from the firm's own website or press release, because no independent source was found for any of them on 21 October 2026.

AI-first development firms in the US

An AI-first development firm, in this guide, is one whose own pages put AI, data and models at the centre of what it sells. Six US firms fit that description: Quansight, Blend360, Aimpoint Digital, Fractal, Quantiphi and Artium. Reveneau and Fluxon come first, each described by what it says about its own work. Five of the six AI-first firms are in Anthropic's partner directory and two sell AI products of their own. Consulting.us reports that a larger firm bought one of them, one says in its own press release that it took a minority investment, and Outlook Money reports that one listed its shares on a stock exchange. Every fact was read on 21 October 2026.

Large consultancies with an AI practice

A large consultancy sells strategy, systems work and staff across many kinds of projects, and an AI practice is the team inside it that does AI work. This guide lists six with US offices: Booz Allen Hamilton, EPAM Systems, West Monroe, Cognizant, Accenture and Slalom. Reveneau and Fluxon come first, described by what each says about its own work. Four of the six are public companies, so their head offices and staff counts come from annual reports filed with the SEC. Every fact was read on 21 October 2026.

Which type of AI development firm to hire

The nineteen firms in this guide fall into three kinds after Reveneau and Fluxon: product studios, AI-first firms and large consultancies. The right kind depends on five things about your project: whether you know what to build, whether the AI is the main job, how many people you need, where they must work, and what you need to be able to check. This page asks those five questions, matches each answer to the firms whose own pages describe that work, and ends with a test you can run before you sign.

Cost and method

What AI development costs across US cities

Only one firm in this guide prints a price figure on the pages read: Think Company lists two offers at "~$50K", and the tilde means the amount is approximate. MojoTech calls one offer fixed-fee and prints no amount. So the main public guide to cost is the wage of the people who do the work. This page gives the US Bureau of Labor Statistics wages for software developers in thirteen metro areas for May 2025, from $107,520 in Grand Rapids to $167,280 in Seattle, and explains what a quote should show.

How these US AI development companies were chosen

Every firm in this guide passed three tests: it names a US office, its own pages describe building AI software for other companies, and it sells that work as a service. Every fact was read on 21 October 2026 and carries a label for its source: the firm itself, a filing with the SEC, an independent outlet, a party to a deal, a platform's partner award or a partner directory. This page explains each test and each label, lists the firms that were checked and left out with the reason, and names what could not be confirmed.

AI development contract checklist

This checklist turns two US government documents and the facts in this guide into questions for an AI development contract. The White House budget office asks federal agencies to test proposed AI systems where they can before they buy, and, in general, to ask for knowledge transfer, data and model portability, clear licences and clear pricing. The NIST AI risk framework asks that test sets and metrics be written down and that organizations have policies for AI risks from outside firms. Print one copy for each firm, ask every firm the same questions, and keep the written answers.

Common questions

Which firms make up this list of US AI development companies?

Nineteen firms. Reveneau and Fluxon come first. Then come Atomic Object, 8th Light, Viget, Think Company and MojoTech, which are product studios; Quansight, Blend360, Aimpoint Digital, Fractal, Quantiphi and Artium, which work mainly on AI and data; and Booz Allen Hamilton, EPAM Systems, West Monroe, Cognizant, Accenture and Slalom, which are large consultancies. Every firm names a US office on its own pages, in a filing or in a news report.

How are the firms in this US guide grouped?

After Reveneau and Fluxon, the firms sit in three groups. Product studios design and build a product with a small team. AI and data firms work mainly on models, data and agents. Large consultancies offer strategy and systems work with AI as one practice. The order inside each group carries no ranking, and no firm receives a score.

Which US metro areas have the most firms in this guide?

Outside the Bay Area, the New York metro area has six firms with an office there: MojoTech, Fractal, West Monroe, Slalom, Accenture and Cognizant, whose head office is in Teaneck, New Jersey. Boston and Chicago have five each. The Washington, DC area has four. Seattle, Atlanta, Los Angeles and Philadelphia have three each. None of the pages read on 21 October 2026 named an office in the Miami metro area.

Why do some entries cite an annual report filed with the SEC?

Booz Allen Hamilton, EPAM Systems, Cognizant and Accenture are public companies, so each files a yearly report called a Form 10-K with the Securities and Exchange Commission. The report is still the company's own statement, but it is a formal one made to a regulator. This guide uses those reports for head offices and staff counts, and says when a filing marks a count as approximate.

How many people work at Fluxon?

Two sources give two numbers. Forbes's company page, with figures as of March 2026, lists 200 employees. Fluxon's own careers page, read on 21 October 2026, says "300+ builders". This guide gives both and does not choose between them. Forbes also lists Fluxon's headquarters as San Francisco, and Stripe's partner directory gives an address at 236 West Portal Ave.

What does Reveneau mean by an eval suite written from the specification?

An eval suite is a set of automated tests. Reveneau says it writes the suite for each project from that project's specification, and that every change must pass the suite before it is released. Reveneau says the suite is graded by a model called Jev, which makes the suite run ten times faster than its previous grader did. These are Reveneau's own statements about its own work.

How should a buyer read a partner award from Databricks?

Databricks sells a data platform and runs awards for firms that build on it. In 2024 it named Aimpoint Digital, Slalom, and pairs including Infosys and EPAM, Cognizant and LTIMindTree, and Accenture and Avanade. An award shows that Databricks values the firm as a partner. Databricks earns money when its partners sell its platform, so treat the award as a partner's praise.

Which firm in this guide says it keeps all of its hiring in the US?

Atomic Object. Its AI development page says it hires only in its four US regions and does not send a client's project team overseas. Its offices are in Grand Rapids, Ann Arbor, Chicago and Raleigh. That statement comes from Atomic's own page. No independent source was found for Atomic Object when this guide was checked on 21 October 2026.

What is the median wage for a software developer across the United States?

The US Bureau of Labor Statistics puts it at $135,980 a year for May 2025, and the mean, or average, at $148,100. Those figures cover software developers in all industries. The median in the New York metro area is $166,830 and the median in the Grand Rapids metro area is $107,520, so the city a team works in changes the wage behind its price.

Why does this guide cite a memo written for federal agencies?

The memo, M-25-22 from the White House Office of Management and Budget, sets out how federal agencies should buy AI. It tells agencies to test proposed AI systems where they can before they choose one, and, in general, to ask for knowledge transfer, data and model portability, clear licences and clear pricing. A private buyer has no duty to follow it, but its points work as a checklist for any contract.

Which firm in this guide works mainly for government agencies?

Booz Allen Hamilton. Its Form 10-K for the year ended 31 March 2026 calls it the federal government's largest AI provider, which is the company's own claim. In 2020 it announced a five-year, $800 million contract for AI services to the Department of Defense's Joint AI Center. Its pages and its filing describe mostly federal customers.

Do Fractal and Quantiphi sell software as well as services?

Yes. Fractal's own site lists AI products of its own, among them Cogentiq and LLM Studio, beside its services. Quantiphi's site lists products called baioniq, Codeaira and Dociphi. When a firm sells both, ask whether your system will depend on its product, what that product costs each year, and what happens to your system if you stop paying for it.
