Pramaana Labs Raises $27 Mn in Seed Round led by Khosla Ventures

Founded in 2025 by IIT Madras alumni Ranjan Rajagopalan, Krishnan Raghavan, and Sanjay Ganapathy, the company develops AI systems that can check whether answers are mathematically and logically correct.

Its technology converts complex information such as tax regulations, medical guidelines, and financial rules into a format that computers can understand. When a user asks a question, the system verifies the answer using a proof engine before providing a response.

If the system is not confident about an answer, it may choose not to respond rather than guess. This helps reduce errors and prevents incorrect verified answers.

The new funding will be used to improve the company’s AI models, expand its research team, and grow its presence in sectors such as taxation, healthcare, cybersecurity, and financial compliance.

"AI has an accountability gap," cofounder and CEO Rajagopalan said in a statement. "Every domain where being wrong can cost someone their health, money, or freedom has rules. Pramaana encodes those rules into a form a machine can reason over with certainty."

Pramaana Labs has brought together researchers and professors from IIT Delhi, IIT Madras, and UC Berkeley to support its AI research efforts. The company also collaborates with Stanford’s Centaur Lab.

Its work in converting tax laws into machine-readable formats is guided by Danny Werfel, the former IRS Commissioner, along with experts from Yale Law School and Stanford University.

The startup has also attracted support from prominent technology leaders, including Google DeepMind Vice President Pushmeet Kohli and Microsoft executive Sriram Rajamani.

Founder Ranjan Rajagopalan previously led the Google Maps Moderation team, while co-founder Krishnan Raghavan worked on Glean’s AI assistant technology.

Co-founder Sanjay Ganapathy was a research engineer at Google DeepMind, where he contributed to the development of Gemini’s tool-use capabilities.
