Missive was created from our own challenges.

It all began with a previous venture, Conference Badge, where it was just the three of us handling support for hundreds of customers.

We needed a better way to collaborate behind the scenes, stay on top of customer requests, and maintain a workspace that we actually enjoyed being in every day.

The existing tools didn’t meet our needs. We didn’t want to use a separate app for customer support, nor did we want another app just for internal conversations about emails.

We decided to keep everything—both work and collaboration—right in the inbox, since that’s where our clients were.

That’s how Missive was born: an elegant and powerful inbox solution for our small team, enabling us to serve customers more efficiently and effectively.

Over the years, Missive became our primary focus. Now, 8 years later, we’re proudly supporting over 4,000 customers and committed to the journey ahead.

Missive is at the forefront of transforming team communication and collaboration. We’re looking for a Back End Developer to join our team and help us continue building our world-class web application.
