Mobile Messaging & Advertising Data Platform
Our mission at OneSignal is to become the ubiquitous platform for all mobile and web notification messages that apps send to users, and we’re well on our way. Our easy-to-use developer SDKs empower developers and marketers to deliver effective push notifications to their users on all smartphone platforms.
We largely bootstrapped our way to 3000 developers and over 120 million end-user devices in less than a year. And now we’ve just raised a $2.3M seed financing round to pour some high-octane fuel onto our already exponential growth.
Our stack includes Ruby, Rails, Rspec, Coffeescript, PostgreSQL, and Redis. Our backend systems currently send tens of millions of notifications per day and process upwards of 60,000 API requests per minute.
