Warburg Pincus-backed Dude Solutions has acquired Windmill Software, underscoring the M&A trends in both the senior living and software spaces.

Toronto-based Windmill develops software for senior living communities that aims to help the centers communicate about operations, including IT, transportation, room bookings and housekeeping. The company's main product, TheWorxHub, is a software service for senior living centers that can be accessed on computers or mobile devices.

Dude, headquartered in Cary, North Carolina, provides operations management software. The acquisition helps the company expand in the senior living market, which it calls "one of the fastest growing market segments in North America."

This is Dude's first acquisition since it announced an up to $100 million investment from private equity firm Warburg Pincus in February 2014. The New York-based firm recently invested in Sterigenics International through a recapitalization transaction, in partnership with Chicago PE firm GTCR.  

There has been a substantial amount of M&A activity in both the senior living and software markets. Recent health care software and technology deals include Sharecare's acquisition of Feingold Technologies, which aims to analyze human behavior via mobile phone, and GI Partners, which bought health care information technology systems group Logibec Inc. in December. Senior living community owner Genesis HealthCare agreed to merge with Skilled Healthcare Group in August.
