Facebook has acquired Beluga, a group messaging technology start-up founded by former Google employees.

Ben Davenport, Lucy Zhang and Jonathan Perlow had launched the company last year.

Beluga allows users to send group messages, photos and location information across multiple platforms.

For Facebook, which has been focused on mobile services of late, the acquisition is an addition to the series of small start-ups teh social networking site has purchased over the past year.

Facebook said the Beluga team will continue their vision for groups and mobile communication as part of Facebook.

Beluga said, "Beluga and Facebook are committed to create new and better ways to communicate and share group experiences."

"For now, Beluga will continue to function as it does today."

Financial details of the transaction were not announced.
