Vine cofounder Colin Kroll announced via Twitter that he is stepping down from his position as Vine's general manager.

Kroll, who cofounded the app that Twitter acquired in late 2012, did not specifically say he is leaving Twitter, but rather stepping away from his day-to-day role. Kroll wrote that he plans to stay on as an advisor.

When another Twitter user responded to ask what's next, Kroll declined to comment further.

I'm so proud of Vine - the team + the product. I'll no longer be working there day-to-day as of today but will remain involved as an advisor

The move comes just 24 hours after Vine launched a new private messaging feature. The update is the app's first foray into private messaging, a space where competitors like Facebook and Snapchat have been for some time. A second Vine cofounder, Dom Hoffman, stepped down from the company in January.
