Frédéric Renken is Co-Founder at Lassie, an AI platform that autonomously handles administrative operations for small businesses, starting with dental practices across the United States.

Frédéric studied Mathematics and Computer Science at the University of British Columbia and built his career as a Software Engineer at Uber before becoming the first product hire at Superhuman.

Frédéric and co-founder Steijn Pelle took an immersive, ground-up approach to building Lassie, spending months working inside a dental practice by hand before writing a single line of code.

Prior to Lassie, Frédéric honed deep product and engineering expertise at Uber and Superhuman, two companies renowned for their high-performance engineering cultures and product-led growth.

Lassie now serves 700+ dental practices across 49 states, saves owners over 250,000 hours of labor annually, surpasses $10M in ARR, and raised a $35M Series A led by a16z at a $250M valuation.
