Join Kepler: AI You Can Trust and Verify.At Kepler, we understand that traditional AI tools often falter when it comes to accuracy. They can misinterpret data, fabricate sources, and provide inconsistent answers. For professionals making multi-million dollar decisions, this inconsistency is not just a minor flaw—it's a dealbreaker.That's why we've developed an architecture that eliminates hallucinations by design. Our AI interprets your intentions, and deterministic code retrieves every figure directly from source documents. Our model never generates arbitrary numbers, ensuring that every output is traceable to a filing, page, and line item. Every calculation is transparent with its formula, making each answer defensible.Our platform is live in production, with access to over 950K SEC filings, 14K+ companies, and 40M+ documents across 27 global markets. We're trusted by firms that cannot afford errors.The architecture we've created is versatile across domains. While finance is our initial focus due to its urgent needs, we plan to extend our capabilities to healthcare, legal, and insurance sectors. Our goal is to build a verification layer for the entire AI stack, not just a finance product.Kepler was founded by Vinoo Ganesh, who has 7 years of experience at Palantir and was Head of Business Engineering at Citadel, alongside Dr. John McRaven, also from Palantir with 11 years of experience, who developed analytics engines for multi-million dollar contracts with major companies.
