The funding will help the company continue to grow sales of an on-demand software product, which was launched about a year ago, according to the CEO. Investors in the round were all repeat backers, including one institutional investor, Waltham, MA-based Polaris Venture Partners, and a group of angel investors. Jon Flint, a general partner and co-founder of Polaris, is on the board at Allurent. Bob made trip to Allurent, and memory lane, to check out the company’s e-commerce software a few years ago.
