Sleeperbot, which has raised about $2M in seed funding from Birchmere VC and Expa, and boasts hundreds of thousands of users, calls itself Slack for sports.

It’s essentially an app (and website) that lets sports fans have conversations around different subjects they’re passionate about. These discussions happen in channels – some of which are created by the company and are general topics like fantasy advice, and some are created by users – like an Eagles fan club.

And now they are adding another feature that is sure to make it even more useful for sports fans – fantasy sports. Starting with NFL this season, Sleeperbot is adding support for season-long fantasy sports right inside its app.

This move makes total sense because season-long fantasy sports, unlike daily fantasy sports, is a very social activity.
