Twitter App Store oneforty Raises $1.6 Million, With More On The Way

Twitter app directory oneforty has raised $1.6 million, according to an SEC filing. Of that, a previously undisclosed $375,000 is in the form of convertible debt already raised in a couple of angel rounds last year (which are converting to stock). So the company was able to raise $1.25 million in new money, and the filing indicates that the total offering amount will be $2.4 million, meaning that more might be on the way before the current Series A round is complete.

Oneforty currently lists more than 2,000 Twitter apps and ranks them based on both their popularity on the site and across the Web. The company makes affiliate revenues for paid apps (mostly on the iPhone), but could eventually charge app developers for featured spots on its homepage. Rumors surfaced in October about Twitter buying the service, but that never happened. Oneforty was part of the Boston Techstars Class of 2009.

Contacted for comment, oneforty CEO Laura Fitton (aka @pistachio) said she couldn’t speak about the funding beyond the information in the filing, but that her charity @wellwishes is raising money for Charity Water this year and the NHL is donating two tickets to the Winter Classic at Fenway Park in Boston. No, I don’t know what that has to do with her funding either.

Update: The likely venture investor is Flybridge Capital Partners, since general parter Jeff Bussgang is listed as a director on the SEC filing.
