Sulia Says Its Homegrown Social Network Is Growing, Raises $6 Million

Sulia started out as a list service for Twitter. Then it turned into a filtering service built with Twitter in mind. Last year, it moved away from Twitter and positioned itself as a standalone “subject-based social network.”

This version seems to be working: The nine-man startup said it is attracting more than 10 million visitors a month, up from four million at the end of 2012.

And investors like the story: Sulia has raised about $6 million in a B round led by Greycroft Partners, along with Metamorphic Ventures; FirstMark Capital, Village Ventures and IA Ventures are all back, as well.

CEO Jonathan Glick has raised $10 million for the various incarnations of his company, but now he says he’s ready to start generating revenue, too. Sulia has begun running “native ads” — of course — on its topic pages, from the likes of Ford; here’s an example on its NFL page.
