Spark Capital

Spark Capital was founded in 2005 by Bijan Sabet, Paul Conway, Santo Politi, and Todd Dagres, built on a deliberately founder-first philosophy that prioritizes people over spreadsheets. The firm's early conviction in consumer internet companies paid off dramatically with Twitter - Sabet led the investment in 2007 when the company had fewer than a dozen employees, years before its 2013 IPO. Spark has since extended that same instinct into enterprise software, fintech, and AI, including an early Series C investment in Anthropic that turned $75 million into an estimated $3 billion.
