AIRBNB, the online accommodations platform, has acquired “travel hacks” tool Vamo for an undisclosed amount.

A statement Friday by Vamo, a startup created by a former Facebook engineer that uses Big Data to help travelers find travel deals, said the service would become part of Airbnb.

“So much has changed since we started, but our vision to make travel better has always been the same,” founder and chief executive Ari Steinberg said in the statement.

“That’s why we’re so excited to join the team at Airbnb. Complexities around international multi-city travel continue to exist, but we believe that in the long run we’ll be able to make even more significant improvements to the future of travel by joining Airbnb.”

Airbnb earlier this year raised $1.5 billion in new capital, sending its value up to $25.5 billion. The company was launched in 2008 and now has some 40 million users worldwide.

Traditional hotel chains see Airbnb as a rival and accuse it of helping people avoid taxes and of hosting illegal hotels on its website.
