Jim Breyer

James W. Breyer (born July 26, 1961) is an American venture capitalist and the founder and chief executive officer of Breyer Capital, a firm focused on technology and innovation investments. Born in New Haven, Connecticut, to Hungarian immigrant parents, Breyer earned a B.S. with distinction in interdisciplinary studies from Stanford University and an M.B.A. from Harvard Business School as a Baker Scholar. He joined Accel Partners in the early 1990s, rising to managing partner, and led the firm's landmark $12.7 million investment in Facebook in 2005, which generated returns exceeding 100 times the initial outlay and established his billionaire status. Over his nearly three-decade tenure at Accel, Breyer participated in investments across more than 40 companies that achieved initial public offerings or mergers, including Dell, Etsy, and Spotify, while also co-founding Accel-KKR. In 2014, he departed Accel to concentrate on Breyer Capital, which has emphasized artificial intelligence, cryptocurrency, blockchain, and healthcare, with recent initiatives including partnerships for AI-driven medicine at Harvard Medical School; the firm relocated its headquarters to Austin, Texas, in 2020. Breyer has held board seats at prominent entities such as Blackstone since 2016, and previously at Facebook, Dell, and Walmart, alongside academic roles including Fellow Emeritus of the Harvard Corporation and chairman of Stanford's Engineering Venture Fund.
