After months of negotiations, Facebook is no longer in talks to acquire Waze, the Israel-based social mapping and navigation startup, according to sources familiar with the matter. The two companies had been in discussion for a potential acquisition, with a price tag that could have reached up to $1 billion. But the talks dissolved in recent days, according to sources, due in part to conflicts over whether or not the Waze team — which is predominantly based in Israel — would move over to the United States and fold itself into Facebook’s Menlo Park, Calif., headquarters, among other reasons. Reps from both Facebook and Waze declined to comment. Waze’s mobile application seemed like a logical acquisition target for Facebook, as Waze relies on crowdsourced traffic data, accident reports and police traps from its 40-million-plus userbase to help drivers better navigate their road trips.
