Group buying site Tippr.com has acquired Austin-based deals site FanForce for an undisclosed sum. This follows the company’s acquisition of fellow deal of the day site ChicagoDeals last week. FanForce offers a white-label Groupon of sorts, allowing small businesses to create their own deals. FanForce takes care of the promotion of deals and offers, sell the vouchers and collect payments. It’s similar in theory to TC Disrupt startup ChompOn, which launched a few weeks ago. The founders of FanForce will join the Tippr management team, including Samy Aboel-Nil who joins Tippr as President/COO, Dane Knecht who joins Tippr as VP of Product Management, and John Whitmarsh, who joins Tippr as CFO. The collective buying space has seen considerable consolidation as of late. Tippr’s competitor Groupon just bought European deal site CityDeal. And with the growing number of similar sites joining the space, I’d expect the consolidation to continue.
