Demo data: 17 companies transcribed by hand from public sub-processor pages and trust centers, captured 3 Nov 2026. AI vendors only; general cloud hosting entries are left out. Pages change, so a row may already be out of date. It is a sample, not a census.

The AI stack sits below the DNS line.

Sales teams at AI vendors already use Clay, Apollo, Outreach and Common Room. None of them can show which accounts run a competitor's model API, inference platform or vector database.

Seven categories

  • Model APIs

    OpenAI, Anthropic, Cohere, Mistral

  • Inference and hosting

    Baseten, Fireworks, Together, Modal, Groq

  • Retrieval

    Pinecone, Weaviate, Turbopuffer, Exa

  • Evaluation and guardrails

    Braintrust, LangSmith, Arize, Lakera

  • Voice

    Deepgram, ElevenLabs, AssemblyAI

  • Agent infrastructure

    Browserbase, E2B, Sierra, Decagon

  • Cloud regions and colocation

    AWS, GCP and Azure by region, Equinix, Hetzner

  • Not tracked on purpose: developer tools and workspace AI seats, which DNS-based tools already see.

Built first for the people selling AI infrastructure.

We applied to the College New Venture Challenge

We submitted ANNX to the University of Chicago's College New Venture Challenge. Here is what we tested before applying and what we committed to.

See the list before you pay for it.

We're taking five to ten design partners: sales teams at AI vendors with 30 to 300 people. You get a free month of lists on your competitors' accounts; we get weekly feedback on one question: did this list produce a meeting you would not otherwise have had?

Everyone else: join the waitlist and we'll email you once when the free lookup opens.
