Hyperlocal newswire Fwix says it raised $2.75 million in a first round from BlueRun Ventures. We reported on Fwix’s official launch last month, but at the time, the company didn’t disclose the amount of its funding. In conjunction with the announcement, the San Francisco-based startup is opening its API platform widely to bloggers and other site publishers. Initially, Fwix launched sites covering nearly 80 cites. By opening its API, the company hopes to quickly expand its reach, though it didn’t offer any numeric goals in the interim.
