Born on March 17, 1969, in Washington, D.C., he grew up in South Florida and earned a Bachelor of Arts in Philosophy from Wesleyan University in 1991, followed by a Juris Doctor from Stanford Law School in 1997. He began his career as a lawyer before transitioning to tech, joining PayPal as a product manager and later becoming executive vice president of business development during its early growth phase as part of the 'PayPal Mafia' network, contributing to PayPal's acquisition by eBay in 2002. Following PayPal, he held executive positions at LinkedIn as Vice President of Business Development and at Slide as Chief Operating Officer, then joined Square (now Block, Inc.) in 2010 as Chief Operating Officer, helping scale its operations and international expansion until 2014. As an investor, he has backed early-stage startups including Yelp and Xoom Corporation prior to their IPOs, insisting on board seats for both.
