In their words

Courier is the fastest way for developers to build notifications for their app. Our APIs take the tedium out of integrating various notification channels, while our visual designer lets anyone design a message template and deliver their notifications to the best channel for each user with a single API call. Email, Push, In-App, Slack, SMS, you name it. Think "Stripe, for notifications."

Is this you?

If you're behind Courier: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. FoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.

Sourced from the company's Y Combinator directory entry.
