This holiday season is the time of year when agents think about making moves. So CAA digital business development executive Matt Mazzeo departed before Thanksgiving to join his Silicon Valley venture capital pal Chris Sacca. Sacca founded Lowercase Capital and hired Mazzeo to head up a new Los Angeles-oriented ‘early stage’ technology fund as the firm’s first partner. Mazzeo will pursue the intersection of media and technology reportedly with capital of $25 million to $35 million to start. A right-hand man to CAA’s head of business development digital Michael Yanover for 7 years, Mazzeo spent the last few years splitting his time between Hollywood and Silicon Valley. I’m told that Mazzeo helped incubate WhoSay while CAA raised $14.4M in outside financing from Comcast Ventures and Greylock Partners. Mazzeo also aided CAA’s effort in creating Funny Or Die. More recently, Mazzeo helped CAA launch Moonshark, a development studio connecting Hollywood talent like Jennifer Lopez and Stan Lee with innovative mobile app concepts. As for Sacca, the investor has held early stakes in Photobucket, Twitter, Uber, Kickstarter, and other ventures. Mazzeo told one tech site that his relationship with Sacco was built on “secret, late-night wine-drinking and jam sessions” at South By Southwest.
