What an Anthropic partner listing tells you about an AI firm

Anthropic makes the Claude family of AI models. It also runs a public directory of firms that build with Claude for clients. Its web address for service partners, claude.com/partners/services, now sends visitors to that directory at partnerhub.claude.com [1]. When the directory was read on 20 October 2026, it held 321 entries.

Most entries have two parts that matter to a buyer. The first is a tier, and Anthropic sets it. The directory showed three tier labels that day: Global Premier on 16 entries, Preferred on 40 and Select on 256. Nine entries showed no tier. The second is a one-line description beside the firm's name, and the partner writes it. So one part of the listing is Anthropic's decision and the other is the firm's own words.

What the directory shows for the firms in this guide

Firm	Directory result on 20 October 2026	Name used in the directory
Reveneau	Not listed, after a search of all 321 entries	None
Fluxon	Not listed, after a search of all 321 entries	None
Ode with Anthropic	Select	Ode with Anthropic
Distyl AI	Not listed	None
Tribe AI	Preferred	TribeAI
Loka	Preferred	Loka
Provectus	Preferred	Provectus
Factored	Preferred	Factored
ClearScale	Select	Clearscale
Thoughtworks	Preferred	Thoughtworks
Slalom	Preferred	Slalom Consulting
Grid Dynamics	Select	Grid Dynamics
Turing	Select	Turing
IDEO	Not listed	None

Six firms hold Preferred and four hold Select. Four are not listed: Reveneau, Fluxon, Distyl AI and IDEO. None of the fourteen holds Global Premier, the tier shown for Accenture, Deloitte, McKinsey & Company and 13 other firms.

What a listing shows

Anthropic names the firm as a partner and sets its tier. The tier is Anthropic's decision, which makes it the one part of the listing that comes from outside the firm.

The firm has a working relationship with Anthropic. A buyer who has already chosen Claude may value that relationship.

The firm's own one-line summary. The description beside each name is the firm's own text. Grid Dynamics, for example, uses its line to say it has helped Fortune 1000 enterprises build AI and digital engineering systems since 2006. That is Grid Dynamics's own statement about itself.

What the pages read did not state

The directory pages read for this guide on 20 October 2026 did not state what a firm must do to reach any of the three tiers. A buyer should therefore treat the tier as Anthropic's label for the relationship, and judge the work by other means.

For the firm's size, prices, clients and engineers, you need other sources. A firm with a Preferred tier and a firm with no listing need the same checks before you sign.

The owner case: Ode with Anthropic

TechCrunch reported in July 2026 that Ode with Anthropic is a $1.5 billion joint venture that Anthropic launched in May with Blackstone, Hellman & Friedman, Goldman Sachs and others, and that Ode works closely with Anthropic's applied AI team [2]. Ode is listed at the Select tier. Because Anthropic is one of Ode's owners, the listing comes from an owner. That is useful to know in two ways. A buyer who wants close access to Anthropic may see the tie as an advantage. A buyer who wants advice that is free of any one model maker may prefer a firm with no such tie.

Firms that are not listed

A missing listing tells you only that the firm was not in the directory on the day it was read. Reveneau's case is covered further down this page. For each of the other three unlisted firms, this guide records a different platform tie or a different type of work.

Fluxon has a listing in Stripe's partner directory, which shows Fluxon as a Verified Partner and a Premier Services Partner, with 2 Stripe Certified Professional Developers [3]. That is a payments partnership, so it matters most for a project that handles payments.

Distyl AI collaborates closely with OpenAI, according to SiliconANGLE [5].

IDEO is a design agency, as Fortune describes it, and its AI Lab sells strategy and design work.

Other partner programmes in this guide

Anthropic's directory is one of several programmes run by platform companies. Each one tells you about the firm's relationship with that platform.

Programme	Firm	What it shows
Anthropic partner directory	Ten firms in this guide	A tier set by Anthropic: Preferred for six of them, Select for four [1]
Stripe partner directory	Fluxon	Verified Partner, Premier Services Partner, 2 Stripe Certified Professional Developers [3]
AWS Partners of the Year, 2024	Loka	North America winner of Innovation Partner of the Year [4]
AWS partnership, by the firm's own account	ClearScale	Says it was started by AWS engineers and builds on AWS [7]

Each listing describes the firm's relationship with one platform company. The firm's work for clients needs its own check.

Where Reveneau fits

Reveneau was not listed in Anthropic's directory when it was searched on 20 October 2026 [1]. By its own account, AI writes 100 percent of its code, and every change has to pass a large eval suite, written from the client's specification, before release. A grading model called Jev scores that suite, and Reveneau says Jev makes it run ten times faster than its previous grader did. Reveneau uses AI in place of hiring more engineers and puts that saving into clients' prices, and it takes responsibility for the whole project through production and after release. For a Claude project, ask Reveneau the same questions as any listed firm, below. The AI development service page describes the work, and the contact page is the place to start.

Questions to ask a firm about its listing

1. Which tier do you hold, and under which name? Some names differ: Tribe AI appears as TribeAI and Slalom as Slalom Consulting.
2. What did Anthropic ask of you to reach that tier?
3. Which Claude models would you use for my project, and why those?
4. If a newer model works better for my project, will you switch? What would that cost?
5. Do you have ties to other model makers? Would you recommend one of their models if it fit better?
6. Can you show your test results for a Claude system on data like mine?

NIST's AI Risk Management Framework, item GOVERN 6.1, asks organizations to have policies for AI risks that come from third parties [6]. A firm's partnerships with model makers are part of that review, because they can shape what the firm recommends.

How to read the one-line descriptions

The text beside each name is the firm's own summary, so read it the way you would read the firm's homepage. Look for facts you can check: an office, a product, a named industry. Treat words that describe quality as the firm's opinion of itself. If a description names a client or a number, look for a source outside the firm before you rely on it.

Some firms appear under a name that differs from the one on their website. Tribe AI is listed as TribeAI, Slalom as Slalom Consulting, and ClearScale as Clearscale. Search for more than one spelling, and for the firm's former name, before you conclude that a firm is missing.

Listings change

The directory is a live page. Firms can join or leave, and a name can change after a sale. Ode with Anthropic was called Fractional AI before the Anthropic joint venture bought it, as TechCrunch reported in July 2026 [2]. Every tier on this page is dated 20 October 2026. Before you sign, open the directory again and confirm the firm's current entry and tier under every name it uses.

If your project does not use Claude

Your project may use models from more than one maker, or you may not have chosen one yet. In that case one model maker's directory covers only part of your choice. Factored calls itself model, cloud and platform neutral on its own homepage, and Distyl AI collaborates closely with OpenAI, according to SiliconANGLE [5]. Ask each firm which models it would test for your project, and ask it to compare at least two on your own data before it recommends one.

How to use a listing in a decision

Use the directory to build a first list if you have already chosen Claude. Then judge every firm on the list, listed or not, by the same tests: a paid task on your own data, written answers to the same questions, and a contract that gives you the code and a way to leave. The questions to ask an AI development company page gives the full set, and the full list shows every firm's entry.
