I am the CEO of General Catalyst, and a founder, investor, and author of four books, including The Transformation Principles (2025).

My vision for General Catalyst (GC) is to be the world's foremost technology investment company, supporting global resilience through applied AI. I first laid out my AI thesis in my 2018 book Unscaled, which explored how the economy of the future will be won by upstarts leveraging AI for hyper-focused markets. I believe in investing in the critical systems that underpin modern democracies and their allies—GC's global resilience thesis—and transforming every industry through innovative partnerships.

I am an early investor in companies like Stripe, Samsara (NYSE: IOT), Snap (NYSE: SNAP), Gitlab (NASDAQ: GTLB), Grammarly, Gusto, Applied Intuition, Anduril, Ro, and Anthropic. My recent focus as an investor has been on Applied AI and sustainability with companies like Crescendo, Re:Build Manufacturing, and Charm Industrial.

My goal is to pioneer a new model for accelerating AI transformation across critical industries through General Catalyst Transformation Companies. As Founder and Executive Chairman of Percepta, I help enterprises across healthcare, financial services, manufacturing, and government become AI-native by deploying world-class teams of researchers, engineers, and product managers directly within organizations and operating a frontier research lab powered by partnerships with AWS and Anthropic.

Healthcare transformation has been a central focus for me throughout my career. My 2020 book, UnHealthcare: A Manifesto for Health Assurance, details the thesis for transforming a "sick care" system into a proactive, accessible, and affordable Health Assurance system. I've helped create several companies to architect this vision, including Livongo (acquired by Teladoc in an $18.5B merger, the largest in digital health history at the time), Commure, Transcarent, Tendo, Homeward, and Hippocratic. As Founder and Chairman of GC’s Health Assurance Transformation Company (HATCo), I work directly with major health systems worldwide to drive their transformations, including via HATCo's acquisition of Summa Health, an integrated health system in Akron, Ohio, in 2025. I was named the most influential Healthcare investor in America by ModernHealthcare in 2023 and 2024.

I started my career as a founder, building a small mobile software company that was acquired, before joining General Catalyst as an entrepreneur-in-residence in 2002. 

In addition to my roles serving on many portfolio company boards, I am also Co-Founder and Chairman of the non-profits Responsible Innovation Labs, Advanced Energy United, and the Health Assurance Foundation, trustee at Northeastern University and on the Stanford School of Medicine Board of Fellows, and a founding board member of Khan Lab School, an innovative K-12 school.

I hold five degrees from MIT: M.Eng. EECS, S.M. Operations Research, S.B. Biology, S.B. Mathematics, and S.B. EECS. And I am a proud husband and father to three kids.
