Online ad company Adknowledge just announced that it has acquired SocialWeekend Labs, a startup that built tools for developers to promote their apps, and also built its own Facebook and mobile apps (such as Birthdays+ and Photos+).

It sounds like Adknowledge is most interested in the startup’s developer tools, as well as its team — the company says it plans to integrate those tools into its own offerings, while continuing to serve existing SocialWeekend customers.

“SocialWeekend has a first-class team of engineers with proven user acquisition expertise,” said Ryan Stephens, general manager of Adknowledge’s Apps business, in the acquisition press release. “They can help us take our already-robust marketing suite for app developers to an entirely new level.”

The SocialWeekend website doesn’t go into too much detail about the startup’s technology, but it says that more than 150 million users have “installed a SocialWeekend product.” It also emphasizes the startup’s strength in analytics, social, scaling and mobile.

SocialWeekend was founded by Shane Walker, Andrew Tso, and Fariz Chowdhury, and it raised an undisclosed amount of funding from Great Oaks Venture Capital, Brad Harrison Ventures, and various angels. The financial terms of the acquisition aren’t being disclosed, either.

The entire SocialWeekend team will supposedly join Adknowledge’s San Francisco office.
