Code Story
Tanmai discusses his journey from creating Hasura GraphQL Engine to building PromptQL's deterministic AI platform.
There's a unicorn AI company that's been flying under the radar — despite counting NASA and the U.S. House of Representatives as customers.
Hasura hit $1B+ status by becoming the invisible infrastructure for GraphQL, the API standard powering much of today's internet. Its next act, PromptQL, is growing 5X as fast. Across our portfolio of Founders Fund, a16z, and Sequoia-backed startups, PromptQL stands out for one reason: it's solving what may be AI's fatal flaw — hallucinations.
Even GPT-5 still produces "confidently wrong" answers, making it unusable for high-stakes enterprise decisions. PromptQL fixes this by deterministically mapping every table, file, and microservice inside a company — no RAG guesswork, no embeddings — returning results with 0% hallucinations, full transparency, and self-correction.
PromptQL is quietly becoming the accuracy layer Fortune 500s are building on. CEO Tanmai Gopal has achieved billion-dollar product-market fit twice in three years — first with Hasura's GraphQL engine, now with PromptQL — and can speak in detail about architecture, economics, and real-world enterprise impact.
