Last week, NY-based social networker Meetup announced a new round of funding, sans-price. According to a regulatory filing, the round was for $7.5 million, reports peHUB. In addition to lead investors USV, past backers DFJ and Omidyar Network also participated. This is the company’s fourth round, and they’ve held numbers close to the vest in fact, though we do know that eBay’s (NSDQ: EBAY) investment in them was $2 million. No word on valuation.
