We're changing push.

Our mission 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.

Our stack includes Ruby, Rails, RSpec, CoffeeScript, PostgreSQL, and Redis. Our backend systems currently send approximately 1 billion notifications per day and process upwards of 1 million API requests per minute.
