http://www.techcrunch.com/wp-content/uploads/2008/12/crvfacebook.jpgForget using Facebook to hook up with random girls or guys. Venture fund Charles River Ventures is using it to find a hot startup or two. Eagle-eyed reader Rishi Mandal saw the ad to the left today, which says “Running a hot startup? Learn more about Charles River Ventures and how we can help you. We are actively investing in great entrepreneurs and big ideas.”

Usually VCs get way more business plans in their inbox than they can even read. But CRV, which is a traditional venture fund (meaning they tend to make larger investments than most very young startups need), also has a “Quick Start” program where they invest smaller amounts in very early startups. Some of those investments have done well, which explains why they’re trolling Facebook for more. I expect their competition will be there shortly as well.
