UPDATED: He's leaving to dedicate more time to working with startups, and because he's been on each board for a long time and was ready to move on, a source close to Breyer told us. He also wants time for his newest board, Harvard University, reports TechCrunch's Josh Constine.
Forbes' Tomio Geron first spotted the news, noting that Breyer really helped catapult his venture firm, Accel Patners, into star status with his investment in Facebook. In 2005, after meeting Mark Zuckerberg, Breyer invested $12 million, gaining an 11% stake, Geron reports. Breyer has been on Facebook's board ever since.
He's been on Walmart's board since 2001, helping the retail giant establish its ecommerce site. He invested in Walmart.com, which began as a venture-backed company and was later bought by Walmart.
