Earlier today, I dropped by the TechStars NY office to check out some of the startups in its inaugural class in New York City before they do their big Demo Day next week. The place was buzzing, and the startups I saw were all way more polished than I expected. I wasn't the only one there to get an early peek. Rich Miner of Google Ventures and Mark Suster of GRP (and also a regular TechCrunch contributor) were there mentoring some of the startups, but also—let's be honest—getting an early look before the throngs of other investors descend upon Demo Day next week. While I was at TechStars, I shot the video above of founders Brad Feld , David Cohen and New York managing director David Tisch . Feld doesn't think that valuations are out of whack, or that the supposed $4 million line is even a rational way to look at it. But there definitely is a rise in interest from follow-on investors.
