Fresh from closing its purchase of newsreading app Pulse, LinkedIn has made another acquisition to dive deeper into the mobile space. TechCrunch has found out, and confirmed, that the social network has aqui-hired Maybe, the social polling startup founded by Omar Hamoui — the man who set up, ran and then sold mobile ad company AdMob to Google for $750 million.

All staff from Maybe, except for Hamoui himself, are now at LinkedIn and working in its mobile division. That includes four engineers and one designer, LinkedIn has told us. Meanwhile, Maybe itself has now shut down. Financial terms of the deal are not being disclosed.

Maybe first emerged in June of last year, a startup that was incubated and spun out of Hamoui’s now-defunct startup generator Churn Labs.

Maybe was one of the contenders in the area of polling startups — an area that has seen some other M&A activity, specifically with the acquisition of GoPollGo by Yahoo. Others include Seesaw, Fashism and Thumb.

It’s not clear why Maybe closed up shop so fast. Maybe because the polling space is so crowded? Maybe because Hamoui is working on something else? Maybe because LinkedIn made Maybe an offer it couldn’t refuse? LinkedIn is not commenting further, and we have not yet heard back from Hamoui himself. Maybe we will update when we do.
