Fitbit on Wednesday announced an acquisition deal with smartwatch maker Pebble. The company clearly has been struggling, having laid off 25 percent of its staff earlier this year, when CEO Eric Migicovsky acknowledged that money was tight. “Fitbit is acquiring certain assets of Pebble, including key personnel and intellectual property specific to software and firmware development,” a Fitbit spokesperson said. “The majority of Pebble employees in the software engineering function … will join Fitbit.”
