Our mission is to become the ubiquitous platform for all web and mobile push notifications, and we’re well on our way. We now have over 24,500 developers and 470 million end-user devices using our service.

Our 100% free notification service is subsidized by our powerful data platform that helps marketers and researchers better understand mobile users to create more effective advertising campaigns.

We’re backed by top investors including YCombinator, Justin Kan, SV Angel, and Rakuten Ventures.

Our stack includes Ruby, Rails, Rspec, Javascript ES6, PostgreSQL, Redis, and Rust. Our blazing-fast, highly reliable backend systems currently send tens of millions of notifications per day and process up to 130,000 API requests per minute. Our Rust-based notification delivery server might be the world's fastest. We’re a small and experienced generalist team, and we’re now looking to expand our ranks.
