Chroma DB users list

Email list of companies using Chroma DB

Q: How many companies use Chroma DB?

Data InfoMetrix tracks 30,023 companies using Chroma DB, with 135,104 verified contacts at those accounts as of October 2026. The largest groups are AI Startups, Developer Tools and Education Technology. Counts are estimates from our database and market research, so ask us for a live count for your exact criteria.

Q: Who buys and manages Chroma DB inside a company?

Chroma DB is usually owned by Developer-First Vector Database. Decision-makers include CTO, Founder / CEO and VP of Engineering; AI Engineering Lead and Staff Engineer shape the choice, and AI Engineers and Backend Engineers use it day to day. Our Chroma DB list can include any of these roles.

Q: Which Chroma DB products or editions can I target?

You can target accounts by the Chroma DB products they run, including Chroma Open Source, Chroma Cloud, Chroma Embeddings, Chroma Distributed and Chroma Search. Tell us which edition or module matters and we filter the list to those accounts.

Q: What other software do Chroma DB customers use?

Chroma DB customers commonly also run LangChain, LlamaIndex, OpenAI, Python and Vercel. We can filter any list by this kind of stack overlap.

Q: What are the main alternatives to Chroma DB?

The main alternatives to Chroma DB are Pinecone, Qdrant and pgvector. We also keep verified user lists for Pinecone and Qdrant, which is useful for competitive displacement campaigns.

Q: When are Chroma DB customers most likely to buy?

Buying triggers we track for Chroma DB accounts include prototype to production, seed funding, Chroma Cloud migration and AI feature launch. A common pain point is RAG retrieval quality: poor retrieval leads to wrong answers.
