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.

Terminal has raised over $27M in funding including a $17M Series B led by 8VC, serves 100+ clients including Hims&Hers, iCapital, and Grindr, and is on track for nearly $50M in gross revenue.

Casey Winters is a co-founder and CEO of SuperMe, an AI-native professional network backed by Greylock and Reid Hoffman. He is one of the most respected growth and product operators in Silicon Valley, having scaled Grubhub from 40,000 customers in 3 cities to 3 million users in 1,000+ cities, then led Pinterest's growth from 40 million to 400 million users, and later served as CPO of Eventbrite through a pandemic that wiped out the live events industry. 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.
