The Art & Science Of Choosing Which Startup To Join & How To Value Your Equity w/ Billy Gallagher, CEO @ Prospect
The Crew PodcastShow Notes
Billy’s Background Billy Gallagher is the founder and CEO of Prospect, a robo-advisor that helps startup employees better manage their private company equity. Think: Wealthfront for startups.
Before Prospect, Billy was on the investing team at Khosla Ventures, where he worked on early-stage deals from seed through Series B, including companies like Stripe, DoorDash, and Instacart. He then joined Rippling as the 34th employee in a generalist "special projects" role, staying for three and a half years as the company scaled to over a thousand people. Between Khosla, Rippling, a Stanford MBA, and a stint covering startups at TechCrunch, he's seen the startup equity problem from literally every seat at the table
The gap he kept seeing between how professional investors managed equity at Khosla vs. how employees fumbled through it at Rippling is exactly what led him to start Prospect.
