Charles River Ventures' New Fund (and the Twitter Back-Story)
Among CRV's more recent investments they list in the official press release are Nantero, Scribd, Vlingo, and Twitter.
Curious story about Twitter... CRV only has about $250K in that company, which has raised $55 million in total. CRV had invested in Twitter founder Evan Williams' earlier venture, Odeo, which didn't take off. Williams decided to repay the investors and go off and do Twitter. (The technology for it had been an offshoot of Odeo.) When Twitter started raising funds, Charles River put in that quarter-million early on, but hasn't participated in any rounds since, and doesn't have a board seat. (But Twitter is listed as one of CRV partner George Zachary's investments.)
Also interesting that TechCrunch lists CRV as a Menlo Park firm. While a lot of its activity has been out West, five of the eight investing partners for this new fund are based in Waltham, Mass. (all but Bill Tai, George Zachary and Saar Gur.)
