OneSignal is building the best platform for businesses to intelligently engage with customers across every channel. We provide a simple interface to push notifications, email, SMS, and in-app messages, letting content creators focus on quality user engagement instead of complex implementation. When you pick up your smartphone, the first thing you see is a push notification - maybe there’s a breaking news alert, a message from a dating site, or football scores… Whatever it is, chances are it came from us.
