Luke Groesbeck is the co-founder and CEO of Foundation, the buyer experience platform that drags homebuilding - one of the last big offline industries - online. After two decades building and scaling Silicon Valley startups including the now-public Opendoor and Eventbrite, he teamed up with two Opendoor colleagues to build what they call 'Shopify for homebuilders': white-labeled apps that carry a buyer from first tour through closing and into the warranty years. Backed by Y Combinator's Summer 2023 batch, Foundation grew 5x in 2025 and now powers the homeowner apps of more than 40% of the top-200 U.S. builders.

A longtime Reforge program partner and prolific writer at caseyaccidental.com, Winters is known for first-principles thinking, blunt contrarianism, and a deep aversion to cargo-cult growth frameworks.
