David Kircos
David Kircos is the co-founder and CEO of Quadratic, a collaborative technical spreadsheet that brings Python, SQL, and AI into a familiar grid interface for modern data analysis.
Before Quadratic, David was an engineer at Techstars in Boulder, where he helped design and build software that valued over 2,500 active investments totaling more than $600 million. He later founded Challenger Finance, which was acquired by TIFIN Wealth.
David met his co-founder Peter Mills when Techstars invested in Peter’s previous company, Modern, which was also acquired. Their shared experience in startups and data led them to team up and build Quadratic with the goal of rethinking how teams work with data at scale.
