The company, which was founded in August 2010, relayed the news on its website Friday, which bears the following message: "Update: we've found a new home at Facebook! Although we'll be working on stuff unrelated to Pursuit, keep an eye out for great new features from us there and thanks to everyone who helped along the way."
The site gave no further information. A Facebook rep confirmed the hiring, but declined to elaborate.
According to a report from Inside Facebook last November, Pursuit's purpose was to streamline searches for corporate executives. The idea was that a company seeking a new executive likely had lots of existing employees with qualified candidates in their own networks. If such employees got financial and other types of incentives for identifying such candidates, then they'd be more apt to do so.
