About OneSignal
We started as app developers who wanted an easy way of messaging our users. Finding no good solution, we built OneSignal.
Today, we’re a market-leading customer messaging and engagement solution, offering mobile and web push notifications, in-app messaging, SMS, and email. Our powerful omnichannel platform enables one million businesses to deliver over 12 billion messages daily. Powered by superior architecture, OneSignal is designed to scale with your business and deliver messages more quickly and reliably than the competition. By providing an open API, extensive documentation, free accounts, and intuitive personalization and analytics tools, we help businesses of all sizes provide a seamless messaging experience to create meaningful customer connections.
