David Cowan

Partner

David Cowan is one of the world’s leading investors across cloud infrastructure, cybersecurity, consumer and space technology, launching Bessemer’s practices in the Silicon Valley office. Known for taking chances on the unorthodox, David was the first venture investor in tech’s most beloved video game streaming platform, Twitch, which was later acquired by Amazon.

David has co-founded three cybersecurity companies incubated within Bessemer’s offices: VeriSign (IPO), serving as initial Chairman and CFO; Good Technology (fka Visto, acquired by Blackberry) serving as CEO, and Defense.net (acquired by F5).

He is a two-time graduate of Harvard University, earning degrees in computer science and math and an MBA. David was ranked sixth on the Midas List and tied for fourth in the Midas List of Hall of Fame.

Today he serves on several non-profit boards including Center for Inquiry and the Smithsonian Center for Astrophysics. He is the co-writer of the Silicon Valley mockumentary series “Bubbleproof,” and in his spare time, he sings with an a cappella group.
