Yahoo has made no secret of its ambitions and advances in mobile, earlier this month reporting 450 million monthly active users and search and display mobile ad revenues growing 100%. In CEO Marissa Mayer’s words, Yahoo is a “mobile first company.” Now, sources say that Yahoo has closed in on an acquisition that could potentially boost its role in mobile further: it is buying Flurry, the mobile app analytics and advertising startup, with a price that could be anywhere between $300 million and $1 billion. Kara Swisher is also reporting that Yahoo is interested in the company. As one poster on a Secret note about the rumor described it, “The price will be low if it’s value[d] as an ad tech company, high if it’s valued based on the analytics SDK footprint. Marisa [sic] likes to overpay for things.”
