Facebook has acquired the team behind Sofa, an Amsterdam-based software firm known for its design prowess. The company has announced in a blog post. Sofa is a software and interaction design company.

The company has designed icons for Mozilla, 280 North, Nike and more. It’s also the creator of several pieces of Mac software, including Kaleidoscope (a file comparison tool), Versions (a subversion client), Checkout (a tool for managing retail stores) and Enstore (a tool for managing web stores).

Sofa’s products, Kaleidoscope and Versions, are not a part of this acquisition. Both apps will remain available.

In a statement issues on the company’s blog, the team said: “Facebook is full of talent and has a great culture. We feel challenged and at home at the same time, and can really get things done there. But equally important, we believe that at Facebook, we will be making a real difference to a lot of people’s lives.”

The Sofa team will be moving from Amsterdam to Palo Alto in the coming weeks
