Which SaaS vendors list OpenAI, Anthropic and other AI providers as subprocessors

Read from each vendor's own subprocessor list: which AI model companies, model hosts and AI tools it names, in its own words, with the date we read the list. 124 vendors' lists, read up to 2026-11-09. Further down: counts by provider, Google, Microsoft and Amazon, every row, additions while we watched and the patterns used to count.

By provider

How many vendors name each company, and the spellings they use. A vendor naming a company two ways counts once. The vendors that name an AI provider name a median of 4 such companies; Figma 14, Lovable 13 and Notion 12 name the most.

AI model companies and model hosts

Tools built for AI features

"Name" means any row naming the company is counted: it sells AI models, runs them, or sells tools built for AI features. "Name and AI wording" is for companies that also sell clouds, messaging or plain compute: a row counts only when the vendor's own name or purpose text for it describes AI work. Meta, for example, is on several lists for WhatsApp messaging; only the rows that say AI are counted.

Google, Microsoft and Amazon

Most lists name at least one of the three large clouds, usually for hosting. The table separates the vendors that name the company at all from those whose row describes AI work: Gemini, Vertex AI, Azure OpenAI, AI Foundry, Bedrock, or a purpose such as "AI model provider" or "large language model processing".

The second column is a floor. A vendor whose row says only "cloud hosting" may still run AI features on that cloud; we count what the list says. The rows themselves are in the table below, with the vendor's wording.

Every row, vendor by vendor

One line per vendor and provider: the name and purpose exactly as the vendor's list gives them, and the day we read it. Where a vendor lists the provider more than once (by region, by product), each row is shown.

30 of the 124 vendors name none of the companies on this page. That means their list names none of them, not that they use no AI: a vendor can run its own models, use one through a cloud row that does not say so, or describe providers in general words ("AI service providers"), which no pattern can count.

Added while we watched

We read every list each week and publish a change only after a person has reviewed it. Between 2026-10-12 and 2026-11-09, 9 vendors added 21 rows that name a provider on this page:

"Seen" is the day our reading first showed the row, not the day the vendor added it. Our readings start on 2026-10-05; a provider already on a list then is not an addition here. Every change, AI or not, is on the changes page.

Questions

Which SaaS vendors use OpenAI as a subprocessor?

70 of the 124 vendors whose subprocessor list we hold name OpenAI on it (read up to 2026-11-09): ActiveCampaign, Adobe, Airtable, Amplitude, Apollo.io, Asana, Atlassian, Attio, Box, Brevo, Calendly, Canva, Clay, ClickUp, Cloudflare, Contentsquare, Cursor, Databricks, Datadog, Deepgram, Docker, Drata, Dropbox, Figma, GitHub, GitLab, Grafana Labs, Grammarly, Granola, HubSpot, Intercom, JetBrains, Jotform, Klaviyo, Langdock, Linear, Lovable, Mailchimp, Mailgun, Make, Mentimeter, Miro, Mixpanel, monday.com, n8n, Netlify, Notion, OpenRouter, Perplexity, Pipedrive, Qualtrics, Retool, Sentry, Shopify, Sinch, Supabase, SurveyMonkey, Twilio, Typeform, Vanta, Vercel, Webflow, WeTransfer, WordPress.com, Xero, Zapier, Zendesk, Zoho, Zoom and ZoomInfo. Microsoft's Azure OpenAI Service is counted under Microsoft, because the vendor contracts with Microsoft for it.

Which SaaS vendors use Anthropic as a subprocessor?

60 of the 124 vendors name Anthropic: Airtable, Apollo.io, Asana, Attio, Backblaze, Box, Brevo, Canva, Clay, ClickUp, Cloudflare, Cursor, Databricks, Datadog, Deepgram, Docker, Drata, Figma, GitHub, GitLab, Grafana Labs, Grammarly, Granola, Hostinger, Intercom, JetBrains, Klaviyo, KnowBe4, Linear, Lovable, Make, Microsoft, Miro, Mixpanel, monday.com, n8n, Netlify, New Relic, Notion, Optimizely, Perplexity, Pipedrive, Pleo, Retool, Sentry, Shopify, Smartsheet, Spendesk, SurveyMonkey, Tresorit, Twilio, Vanta, Vercel, Webflow, WordPress.com, Xero, Zapier, Zoho, Zoom and ZoomInfo. A vendor that reaches Claude models through Amazon Bedrock or Google Vertex AI lists Amazon or Google, and is counted there.

How many SaaS vendors list an AI provider as a subprocessor?

94 of the 124 vendors whose list we hold name at least one AI model company or model host. 50 name both OpenAI and Anthropic. A vendor lists the companies it may use; many say a provider is used only when a customer turns an AI feature on.

Download the data (CSV): every row with its source and the date it was read.Cite as: eucsoft, “AI providers on SaaS subprocessor lists”, https://eucsoft.com/en/findings/ai-subprocessors/, data read up to 2026-11-09.

The patterns used to count

Each row's name is tested against these patterns in order, case-insensitive, and credited to the first that matches. For "name and AI wording" the row's name or purpose must also contain one of: AI, IA, artificial intelligence, intelligence artificielle, LLM, large language model, language model, machine learning, generative, GenAI, inference, embedding, Gemini, Vertex, Bedrock, OpenAI, AI Foundry, Agent Platform (as whole words). Rows naming Azure OpenAI go to Microsoft, not OpenAI. A company naming itself or its own group is left out.

Not counted: companies that sell finished AI applications rather than models or tools for building with them (meeting recorders, support chatbots, document parsers), contractors with "AI" in their name that the list describes for other work (voice transcription by people, customer support), and rows that name no company ("AI service providers", "LLM Models"). Every one of those rows is still on the vendor's page and on thesubprocessors page.

How this was read

Each vendor's subprocessor list is read from its own website every week, and names, purposes and locations are kept as written. This page uses the newest reading of each list, third parties only. Nothing is taken from news, other trackers or the AI providers' own customer lists. What each vendor says about training, retention and zero data retention for its AI features is on the AI vendors page; the full method is on the methodology page.
