Auren Hoffman is a Partner at Flex Capital. He is named on the SEC Form D of Flex Capital Fund I, L.P., filed 25 October 2018, and on the Form D/A of Flex Capital Fund II, L.P., filed 13 February 2023, as a managing member of each fund's general partner, which is the clearest documentary evidence of his role at the firm. Flex Capital's own team page describes him as founding CEO of LiveRamp, which was acquired by Acxiom and trades as NYSE: RAMP, as Chairman of SafeGraph, and as having made more than 100 angel investments; his own site summation.net describes him as an investor in over 80 technology companies. Before that he founded Kyber Systems while at Berkeley, founded BridgePath in 1998 which Bullhorn acquired in 2002, co-founded Rapleaf in 2006 and led it as CEO until 2012, was a venture capitalist at Founders Fund around 2011 to 2012, and founded SafeGraph, where he was CEO until October 2024. He holds a BS in Industrial Engineering from the University of California, Berkeley, awarded in 1996. No individual company investment is attributed to him by name in any Flex Capital announcement read, so his notableInvestments is empty rather than populated from the firm's portfolio page.
