Yahoo has announced that it is spinning off Vespa, its big data serving engine, into an independent venture. Joe Bratseth, previously a VP architect in the big data and AI group at Yahoo, has been appointed CEO. Yahoo will continue to invest in Vespa and remain its largest customer following the spin-out, and will also own a stake in Vespa and hold a seat on the spun-out firm’s board of directors. Vespa was created in 2005 after Yahoo acquired Overture, and has since been expanded to handle input beyond text strings, personalize content, and take direction from machine learning algorithms. Vespa is currently used to drive searches and related-article recommendations on Yahoo-owned sites like Flickr, and performs ad targeting on Yahoo-branded web properties.
