On Friday, FeeFighters, the creator of the Samurai payment gateway,announced on its blog that it has recently been acquired by daily deals giant, Groupon.

The post did not reveal the terms of the deal but did mention that there are no plans for major changes to its product line, including the FeeFighters Marketplace, Samurai gateway, and the brands themselves.

TechCrunch reports Groupon’s motive behind the purchase:

“With the FeeFighters acquisition, the focus is clearly on gaining technology aimed to help Groupon’s merchant partners, an area which the company has been diving into more deeply lately, with this month’s launch of the Groupon Scheduler booking service, another product that came out of an acquisition (OpenCal), as an example.”

Sean Harper, co-founder and CEO of FeeFighters, states that the acquisition will help the 3-year-old startup pursue its goal of helping small businesses run more efficiently.
