Powering the world's messages

What we do

We provide a simple, developer-friendly interface to push notifications and email for apps and websites.

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

Today, we are the leading solution for push notifications and email, supporting over 800,014 developers. OneSignal is available on every platform and development environment that supports push, letting content creators focus on quality user engagement instead of complex implementation.

Our goal is to democratize communication tools for everyone from individual blogs to top tier apps.

What we believe

We strive to build a happy, healthy work environment driven by our core values:

We create an environment where each person directly helps the company meet its goals. We hire great people and bring out the best in each other through regular feedback, creating an inclusive and conscientious work environment, providing opportunities for learning, and being humble.

We provide mission-critical products for our clients and they depend on us for exceptional support, highly available service, great documentation, and listening to their feedback. Ensuring the success of our customers is everyone’s responsibility.

Huge leaps are made not by taking the road well traveled, but by trying novel approaches and occasionally succeeding. Because of the nature of risk taking, we celebrate both successes and failures, and we view such failures as a learning opportunity.

We lead by example, putting rigor into our work and communicating with transparency and intellectual honesty. To demonstrate this we set aggressive goals, address issues in their nascency, and take personal responsibility for helping the company meet its goals.

We believe that happiness, fun, and energy fuels creativity and innovation and creates a more open and communicative workplace. We host regular off-sites and social events to bring the team closer together. We’re grateful for our successes and we celebrate them.
