# Nick Fleisher

> Nick Fleisher is the co-founder and CEO of Sandstone, the first platform built for AI-native in-house legal departments. An engineer who once tried to drop out of college to build apps, he later led McKinsey's legal tech and AI practice in New York before reuniting with his freshman-year roommate and a lawyer-turned-engineer to launch Sandstone in 2025. The company raised a $10M seed round led by Sequoia Capital and runs out of Brooklyn, where Fleisher is betting that institutional legal knowledge can become a company's competitive advantage instead of a bottleneck.
