Voxer is a San Francisco based mobile app development company best known for its free Voxer Walkie Talkie app for smartphones.
Founded by Tom Katis and Matt Ranney, Voxer Walkie Talkie is both a live “push-to-talk” system and a voice messaging system. Messages on Voxer are delivered live as they’re being recorded and then delivered as a voice message as well. The app works on Android, Windows Phone and the iOS operating systems. In April 2012, the company raised $30 million in venture financing from Institutional Venture Partners (IVP), Intel Capital and other angel investors.
