Customer support AI agent development companies
A customer support AI agent answers customers by chat, email or phone, looks up their order or account, and passes the case to a staff member when it cannot or should not finish it alone. Reveneau and Fluxon come first. After them, nine firms in this guide say they build agents of this kind: BotsCrew, Galadrim, Thinkia, Lazer Technologies, Mactores, Yellow Tech, Linnify, Bounteous and First Line Software. This page gives the channels each firm names, how it hands cases to people, the results it publishes, and the questions to ask. Every page was read on 21 October 2026.

Key takeaways
- Nine firms in this guide say they build customer support agents. Thinkia and First Line Software sell their own support products, Mactores says its own platform builds the agent infrastructure, and Bounteous and Linnify name their own platform or framework.
- Thinkia, Yellow Tech, Lazer Technologies and Galadrim list voice or phone agents among their offers, and BotsCrew's about page names voice assistants among what it builds.
- BotsCrew publishes support figures for a named client, S&B Filters: "98% faster first response time" and "Up to 50% of requests fully automated". Its case page lists them as "Projected Business Impact" and calls them estimates.
- OpenAI's own guide says actions such as "canceling user orders, authorizing large refunds, or making payments" should go to a person "until confidence in the agent's reliability grows".
A customer support AI agent is a program that uses an AI model to answer a customer and to act on the answer. It reads the customer's message, looks up the order or the account in the company's systems, writes a reply, and passes the case to a staff member when the rules say so. A scripted chatbot follows a fixed set of questions and answers that a person wrote in advance. An agent chooses its next step as it goes, inside the limits the company sets. That freedom is why the company has to set clear limits on what a support agent may do.
This page lists the firms in this guide that say they build support agents. Reveneau and Fluxon come first, and the other nine follow in the guide's order, which gives no ranking. Every fact is marked with its source. A firm's own case study is its own account, and no outside source checked any support result on this page. Anthropic's partner directory, Anthropic's list of service firms that work with its Claude models, gives most firms a tier, set by Anthropic: Global Premier, Preferred or Select. The full list of AI agent development companies has the size and office of each firm.
What a support agent is allowed to do
OpenAI, which makes the GPT models, publishes "A practical guide to building agents" [1]. It says an agent needs a way to pass control to a person "when it can't complete a task", and adds, "In customer service, this means escalating the issue to a human agent." It then says, "Two primary triggers typically warrant human intervention." The first is "Exceeding failure thresholds", with the advice, "Set limits on agent retries or actions." Its example is an agent that "fails to understand customer intent after multiple attempts". The second is high-risk actions: "Actions that are sensitive, irreversible, or have high stakes should trigger human oversight until confidence in the agent's reliability grows. Examples include canceling user orders, authorizing large refunds, or making payments." That is OpenAI's own guidance, and it gives a buyer a clear question for every firm: which actions may your agent take alone, and which go to a person?
A support agent's answers matter as much as its actions. In Moffatt v. Air Canada, decided in February 2024, British Columbia's Civil Resolution Tribunal held Air Canada responsible for wrong fare information that its website chatbot gave a customer [2]. That bot answered questions and took no actions. How to test an AI agent before you buy covers the case in full.
Reveneau and Fluxon
Reveneau offers a service to build a company chat assistant and a service for AI development. By its own account, AI writes 100 percent of its code, and each change has to pass a large eval suite, a set of automated tests written from the project's specification, before it is released. Reveneau says Jev, the model that grades the suite, makes the suite run ten times faster than its previous grader. It says it uses AI in place of hiring more engineers and puts that saving into the prices clients pay, and that it takes responsibility for the whole project through production, the live system people use, and after release. Its offices are at 435 Utah Street in San Francisco and on Floor 33, 909 Mainland Street, in Vancouver. Anthropic's partner directory had no Reveneau entry when its 321 entries were searched on 20 October 2026.
Fluxon's AI development page lists "Agents & multi-agent systems" among the things it builds, and says they reduce the time and cost of complex work "while keeping people in control" [3]. A multi-agent system is one in which several agents pass work between them. No support agent case for a named client was found on its pages. Its own site shows Google, Zapier, Puzzle, Eppo and Braintrust as clients. Anthropic's directory had no Fluxon entry on 21 October 2026.

The firms
BotsCrew. Its homepage case for S&B Filters describes an order-status assistant that works with NetSuite, a business system for orders and accounts, with one assistant for support staff and one for customers on the website [4]. The homepage says an earlier system that connected Claude straight to NetSuite "never reached production", and that BotsCrew "rebuilt the approach from scratch" [13]. It gives three results for that work: "98% faster first response time", "$140k annual cost savings" and "Up to 50% of requests fully automated". The case page lists the same figures, with the 50% given without "Up to", under the heading "Projected Business Impact", and says, "Estimates are based on pre-implementation ticket volume, average handling time reduction driven by AI-assisted responses, and typical support agent cost benchmarks." These are BotsCrew's own estimates, and no outside source checked them. Its customer service page says buyers can "Instantly switch from automated flow to Live Chat" and "Provide the context to your agents", where "agents" means the human support staff who take over the chat. Anthropic lists BotsCrew at the Select tier.
Galadrim. Its agents page lists "Conversational Agents and RAG" and "Voice and Multichannel Agents" among its offers [5]. RAG, short for retrieval-augmented generation, means the agent looks up the company's own documents before it answers. Its test method, by its own description, includes testing "the system on out-of-scope requests and circumvention attempts", meaning questions the agent should refuse and attempts to trick it. Anthropic lists Galadrim at the Select tier.
Thinkia. Its AI Contact Experience product "Resolves queries 24/7 across voice and chat" and "Decides when AI should hand off to a human and who should take the call. Context travels with the transfer." [6] In plain words, the staff member who takes the call sees what the customer already said. This is a product Thinkia owns, so part of what a buyer pays for may be a licence for that product. No named client case was found on its pages. Anthropic lists Thinkia at the Select tier.
Lazer Technologies. Its AI page lists "Customer-facing agents: support triage, sales qualification, voice automation" [7]. Support triage means sorting incoming requests by type and urgency, and sales qualification means asking a new contact the questions that show whether they are likely to buy. Its clients page says, of Hinge, "We helped them build a proof-of-concept for a support chatbot in their app." A proof of concept is a first version built to show that an idea works. Its clients page also lists Decagon, a company that sells support agents, and does not say what Lazer built for it. Outside Anthropic's Select tier, these facts come from Lazer's own pages.
Mactores. Its AI agents page says, "Mactores transformed Safaricom's customer-support experience into an agentic platform. Customers stopped navigating menus and started asking in their own words." [8] An agentic platform is a system built on agents. The same page says its "Forward-deployed engineers own the architecture decisions", including "what the agent is allowed to do, what humans must approve". It also says, "Aedeon builds the agent infrastructure. FDEs design the agent behavior." Aedeon is Mactores' own platform, and FDEs is its short name for its forward-deployed engineers. It promises a fixed date and a fixed fee and prints no amount. Outside Anthropic's Preferred tier, these facts come from Mactores' own pages.
Yellow Tech. Its AI Factory page lists voice agents that "answer the phone 24/7 and in several languages" and "Customer Agents Front office on chat, WhatsApp, social media and email." [9] Front office means the work that faces customers. It describes the difference in one line: "A chatbot answers the question and stops there." Its document agents send exceptions "to human review". Anthropic lists Yellow Tech at the Select tier.
Linnify. Its AI page quotes a client who credits a conversational agent with helping customers find their way through technical product data, and with showing the client where its product materials needed work [10]. The page names the speaker only as a marketing director. Linnify builds on its own agent framework, which it calls ARC, and says the client keeps "your data, your agents, and your IP". IP means intellectual property, the rights to what was built. Outside Anthropic's Select tier, these facts come from Linnify's own pages.
Bounteous. Its Salesforce partner page lists Agentforce Service, Salesforce's own agent product for customer service, among the products it works with. Its agentic page names its own "Agent Management Platform" with "built-in governance and human oversight" [11]. No published support result was found on the pages read. Outside Anthropic's Preferred tier, these facts come from Bounteous' own pages.
First Line Software. Its product Jaime "automates customer conversations, qualifies leads, and answers support questions" [12]. Jaime is a product First Line Software owns and sets up for each client, and its directory text names real estate, healthcare and hospitality as its industries. Outside Anthropic's Select tier, these facts come from First Line Software's own pages.
Three questions for every support agent firm
First, ask which actions the agent may take alone and which go to a person. Use OpenAI's examples, order cancellations, large refunds and payments, as a starting list, and write the answer into the contract.
Second, ask how a case reaches a person and what the person sees. Thinkia's product page describes passing the conversation history with the call. BotsCrew's describes a switch to live chat. Ask each firm to show this in a test with your own staff.
Third, ask for results on a support case like yours, with the measurement behind them. BotsCrew's "Up to 50% of requests fully automated" is an upper figure, in its own words, for one client, and its case page calls the figures estimates. Ask what share of requests the agent finished alone over a full month, and how many of those answers a person checked. What AI agent development costs covers what to ask about price, and the AI agent evals guide explains how such tests are built.
Common questions
How is a customer support AI agent different from a scripted chatbot?
A scripted chatbot follows steps a person wrote in advance, such as a menu of questions and fixed answers. A support agent uses an AI model to choose its next step as it goes: it reads the message, looks up the order, writes a reply and decides when to pass the case to staff. That freedom means the company has to set limits on what the agent may do.
Which firms in this guide offer voice or phone agents?
Thinkia's AI Contact Experience product handles voice and chat around the clock. Yellow Tech lists voice agents that answer the phone in several languages. Lazer Technologies lists voice automation among its customer-facing agents, and Galadrim lists voice and multichannel agents. BotsCrew's about page names voice assistants among what it builds. All of these descriptions come from the firms' own pages, read on 21 October 2026.
What does Thinkia's contact-centre product do when a call needs a person?
Thinkia's page says its AI Contact Experience product decides when the AI should pass the conversation to a person and who should take the call, and that the context travels with the transfer. In plain words, the staff member sees what the customer already said. The product belongs to Thinkia, so ask what a licence for it costs each year.
What results does BotsCrew publish for its S&B Filters assistant?
Its homepage gives three: 98% faster first response time, $140k annual cost savings, and up to 50% of requests fully automated. The case page lists them as Projected Business Impact and says they are estimates based on ticket volume before the work and typical support staff costs. The work was an order-status assistant that works with NetSuite. No outside source checked the figures.
When does OpenAI's guide say a support agent should pass a case to a person?
OpenAI's guide says two triggers typically call for a person. One is going past a set limit on retries or actions, such as failing to understand what the customer wants after several attempts. The other is a high-risk action, such as cancelling an order, approving a large refund or making a payment, which should go to a person until confidence in the agent grows. That is OpenAI's own advice.
What does Mactores say it built for Safaricom?
Its AI agents page says Mactores turned Safaricom's customer support into an agentic platform, and that customers stopped navigating menus and started asking in their own words. The page gives no measured result for that work in the text read for this guide. The statement is Mactores' own, and Safaricom's own account was not read.
Which firms in this guide name Salesforce Agentforce for support agents?
Bounteous's Salesforce partner page lists Agentforce Service, Agentforce Sales and other Agentforce products, which are Salesforce's own agent tools. Galadrim's site menu has a Salesforce & Agentforce item. Both are the firms' own pages. If your customer records already live in Salesforce, ask whether the agent would run inside Salesforce or beside it.
Which channels do Yellow Tech's customer agents cover?
Its AI Factory page lists chat, WhatsApp, social media and email for customer agents, and separate voice agents that answer the phone around the clock in several languages. It also builds document agents that check invoices and orders and send exceptions to human review. Yellow Tech's directory text says it works in Italian organisations. All of this comes from its own pages.
What did Lazer Technologies build for Hinge?
Lazer's clients page says it helped Hinge build a proof of concept for a support chatbot in its app. A proof of concept is a first version that shows an idea can work. The page does not say whether the chatbot went live. Hinge's own account was not read, so the statement is Lazer's own.
Which Reveneau services relate to chat assistants?
Reveneau offers a service to build a company chat assistant, described on its own service page, and a service for AI development. By its own account, AI writes all of its code and every change must pass a large eval suite, a set of automated tests written from the specification, before release. Reveneau says it takes responsibility for the whole project through production, the live system, and after release.
What should a buyer measure in the first month of a support agent?
Count how many requests the agent finished alone, how many it passed to staff, and how many of its answers a person checked and found wrong. Compare the time customers waited for a reply with the month before the agent started. BotsCrew's figure of up to 50 percent is an upper figure and an estimate, in its own words, so ask every firm for the full-month figure on your own requests.

Back-office AI agent development companies
Back-office work is the internal work customers never see: checking invoices, handling claims, reading contracts, writing reports and approving requests. Fourteen of the fifteen firms in this guide after Reveneau and Fluxon say they build agents for work of this kind. This page gives the tasks each firm names, who approves the agent's work, and the results each firm publishes about itself, with every hedge kept. Awiant's invoice result says how it was measured: by the customer's own estimates. Every page was read on 21 October 2026.
Coding agent development companies
A coding agent is an AI program that reads a task, changes a company's code, runs the tests and proposes the change for review. Reveneau and Fluxon come first. After them, nine firms in this guide offer to bring coding agents to a client's own engineering team: Thinkia, Lazer Technologies, Cay Digital, Zemoso Labs, AscentCore, Diverger, HAVIT, Bounteous and First Line Software. This page gives what each firm offers, the points where a person approves the agent's work, and the figures each firm publishes, all of them its own. Every page was read on 21 October 2026.
