OneSignal

We started as app developers who just wanted a developer-friendly API for push notifications. Finding no good solution, we built one ourselves.

Today, OneSignal is the leading solution for sending effective messages across channels including mobile push notifications, web push notifications, in-app messaging, SMS, and email. We support over 1,800,000 of the world's leading marketers and developers.

OneSignal is available on every platform and development environment, letting content creators focus on quality user engagement instead of complex implementation.

We are growing faster than ever, and hiring in all departments. We hope you'll apply and we look forward to meeting you!
