Social Capital

Social Capital is a technology investment firm founded in 2011 by Chamath Palihapitiya (a former Facebook executive) and headquartered in Palo Alto, California, with co-founders Mamoon Hamid and Ted Maidenberg. Originally a traditional venture fund that stood out by backing healthcare, financial services, education, and other hard, regulated sectors the VC community had neglected, the firm pivoted in 2018 into a technology holding company that stopped accepting outside capital and now invests from its own permanent balance sheet of roughly $2.1B, aiming to "earn like Berkshire Hathaway and invest like the Red Cross." Its thesis targets multiple emerging $10T markets across deep tech commercialization, life sciences and drug discovery, the global energy transition, and creator-economy media. Chamath became known as the "SPAC King" for taking companies public through the Social Capital Hedosophia (IPOA-IPOF) vehicles, including Virgin Galactic, Opendoor, Clover Health, and SoFi. Notable investments include Slack, Box, SurveyMonkey, Wealthfront, Netskope, Intercom, Groq, Palmetto, Saildrone, and Relativity Space.
