Biography
David graduated with Honors from Stanford University, where he was a member of the varsity Swimming & Diving Team, which went on to win multiple Pac-10 and NCAA Championships. He later earned an MFA from the USC Film School in 1989 and an MBA from Stanford Business School in 1993.
Having founded global syndicate barter company EastNet in Moscow and Eastern Europe, he graduated from business school and joined Capital Research, which became the largest mutual fund in the world as measured by assets under management after he left.[2] In his tenure at Capital Research, he focused on the Technology, Media & Telecommunications sectors, and his fund was an early investor in Yahoo!, eBay, Amazon, PayPal, and America Online.[3] His investments were a key component of a top-performing growth fund, which led to Siminoff being named "Best of the Buy Side" by Institutional Investor Magazine and receiving numerous accolades from financial industry publications, including Forbes, The Wall Street Journal, and Fortune.
MySpace founder Chris DeWolfe observed, "Siminoff is an artsy guy in a suit who puts the literature of what sites do above anything else, even though he's trained as a finance guy. He was a great advisor for us as we scaled - he has a really clear vision for what's coming in the world. Entrepreneurs are clearly at the top of his pyramid."[4]
The Wall Street Journal noted that Web executives call him "The Smoking Man," after the mysterious character on television's "X-Files," who pulls the strings behind the scenes.[1]
Institutional Investor Magazine remarked, "You can look at him from a Wall Street perspective or an industry perspective. David's very close to the Technology community and has a solid sense of what's going on in the Media and Technology businesses. There aren't a lot of investors who get that convergence."
Siminoff later served as the Chief Executive Officer of Spark Networks, a publicly traded firm which is the parent company of JDate. He was a general partner at Venrock, the Rockefeller family's venture capital arm.
With his wife, Ellen Siminoff, the couple have been an angel investors/advisors for dozens of successful Silicon Valley start-ups, including StubHub, richrelevance, Tonic Generation, SlideShare, BlogHer and Crunchyroll.
