THE HARDEST PROBLEMS AREN’T UNSOLVABLE.THEY’RE Unformalized.

For three thousand years, every field humanity formalized stopped being a matter of opinion. Nobody argues about the Pythagorean theorem. Nobody double-checks a compiler. But tax, law, and medicine still run on expert intuition: brilliant, expensive, contradictory, and impossible to verify. Pramaana Labs exists to change their category. It is a frontier lab converting the unformalized world, from 7,000 sections of tax code to statutes and clinical guidelines, into machine-checkable logic that produces answers with proofs attached.

Their system carries a one-sided guarantee no LLM can make: when it answers, it is provably right, and when it cannot prove an answer, it says nothing at all. The three founders met as math Olympians at IIT Madras and spent the last decade inside the systems the world already trusts, from Gemini's tool-use team to Google Maps to high-frequency trading, before betting everything on the layer AI is missing. A $27M seed led by Khosla Ventures. BoldCap in from Day Zero, before there was anything to notice.
