Team
Spark Capital was founded in 2005 by Bijan Sabet, Paul Conway, Santo Politi, and Todd Dagres. Over time, other partners joined, including Jeremy Philips, Alex Finkelstein, Yasmin Razavi, Will Reed, and Nabeel Hyatt. The firm employs approximately 11 to 50 people, reflecting its size as a mid-tier venture firm. Notable partners have held board seats at portfolio companies, shaping the governance of startups such as Twitter and Cruise.
Investment approach
Spark Capital has been known for co-investing with Union Square Ventures, particularly in its early consumer internet deals. Many early picks, including twitter, Tumblr, and Foursquare, were made via partner B Sabet and were joint investments with Union Square Ventures led by Fred Wilson. Sabet has noted that portfolio companies do not use non-compete agreements, which he claims have been a key factor in limiting startup growth in New York and Boston.
Spark is known for its early Series C investment in Anthropic, turning a $75 million investment into $3 billion. This bet underscored the firm's willingness to back Artificial intelligence ventures before they became widely recognized, positioning Spark at the center of the AI investment wave.
Companies
Spark has been or is an early institutional investor in numerous companies. In fintech, it led the Series B for Affirm, with Jeremy Philips joining the board, and backed Coinbase, Deel, and Ramp. Yasmin Razavi led the Series C for Anthropic in 2022, while Nabeel Hyatt co-led the $150 million Series A for The Bot Company, a venture by Cruise founder Kyle Vogt. Spark also invested in Cruise's Series A, with Hyatt joining its board, and supported Discord, where Hyatt served as an observer. Others in the portfolio include Slack and Oculus VR, which was acquired by facebook for roughly $2 billion, with Santo Politi joining the Oculus board.
Early investments in Twitter and Tumblr were particularly significant. For Twitter, B Sabet invested in the Series B in 2008, later taking a board seat and helping smooth leadership transitions in 2008 and 2010, including the appointment of Evan Williams and then dick-costolo-ekiva. Tumblr saw a co-investment with Union Square Ventures, and when Tumblr was sold to yahoo for $1.1 billion, Spark and Union Square each took home $192 million. These deals defined Spark's early success and established its reputation as a key player in the consumer web.
