This is an interesting addition for Advancit Capital, the investment firm launched two years ago by Shari Redstone, who runs National Amusements and happens to be the daughter of (and could be a successor to) Viacom and CBS Chairman Sumner Redstone. Jonathan Miller is a big league player: He was considered for the top job at Yahoo last year after having served as News Corp’s Chief Digital Officer, CEO of AOL, and founding partner of investment company Velocity Interactive Group. He’s now a partner at Advancit, which focuses on early stage investments. “Against this backdrop of rapid evolution in the digital media space, we’re here to help great entrepreneurs build amazing companies,” Miller says today. In addition to investing cash, Advancit says it looks for opportunities to help “talented and passionate entrepreneurs” in media, entertainment and tech by offering a “deep network of industry relationships and strategic support.”
