Portland information-technology firm Winxnet continued its acquisition spree on Tuesday with the announcement that it has acquired Maine Networks, a small IT-services shop in Portland.

Maine Networks marks Winxnet’s third acquisition this year. Terms of the Maine Networks deal were not disclosed.

Jeff Kinney, who founded Maine Networks in 1996, will join Winxnet as a senior account engineer. It’s possible a second employee will also come over to Winxnet.

“We are committed to finding the most talented and capable professionals to join our growing team and customer base,” Chris Claudio, CEO of Winxnet, said in a statement. “Jeff has built an impressive company in Maine Networks that shares our fundamental ideology in delivering unparalleled IT excellence, with a focus on an exceptional customer service experience.”

In April, Winxnet acquired InfoSecurus, a Portland-based information security firm, for an undisclosed price. It followed that up in August with the acquisition of Methuen, Massachusetts-based KSDA Consulting, which added another 40 employees to Winxnet’s workforce and expanded its regional reach.

With the Maine Networks deal, Winxnet’s workforce will increase to 110 employees.

Before this year, Winxnet had never made an acquisition in its 15-year history.

Claudio told the Portland Press Herald in an interview earlier this year that the acquisitions have not been spur of the moment, but are part of the company’s strategic plan. They serve three purposes: High-level talent is hard to find and sometimes it’s easier to gain that talent through acquisition; it allows the company to strengthen service areas; and it will aid in the company’s desired expansion into southern New England.
