Despite having just spent $1.1 billion to acquire Tumblr and rumors that it has its eye on Hulu, Yahoo! very well could be looking to getting into the check-in space, according to CFO Ken Goldman. Goldman spoke at a investment conference, and continued to sound the horn that Yahoo! is not done acquiring companies in the mobile space. He noted "localization of the space," which sounds an awful lot like check-in services. I've opined before that Yahoo! would acquire Yelp ( YELP), which not only lets people check in to restaurants, stores and local businesses, but also provides search and content. Mayer has continuously alluded to the fact that Yahoo! needs "more personalized content and increased product innovation" to get the Internet giant back on track for Display revenue growth. Yelp isn't profitable yet, but revenue growth is soaring, up 68% year-over-year, according to Yelp's latest earnings report.
At a market cap approaching $1.8 billion, Yelp is now probably too big for Yahoo!, especially after the Tumblr acquisition, but that doesn't mean there aren't other alternatives.
A check-in app would continue Mayer's radical transformation of Yahoo! into the world's "daily habit," as she has so often put it. With Tumblr, and the potential acquisitions of Hulu and perhaps a check-in app, Yahoo! is fast becoming the go-to place in Silicon Valley for high-profile acquisitions. Now, all Mayer has to do is deliver on her promises. -- Written by Chris Ciaccia in New York >Contact by Email. Follow @Chris_Ciaccia
