Our leadership principles

These principles guide our behaviors and decision-making processes from everyday projects to company strategy.

Customer obsession

We exist to make customers successful. In everything we do, we start with the customer’s perspective and work backwards.


We own the outcomes of our activities. When we see a vacuum on something important, we jump in — we never say “it’s not my job.”

Self awareness

We seek to understand our strengths and growth opportunities. We are open to feedback and share our ideas constructively and respectfully.

High impact

We align our work to our shared vision and stay focused on top priorities. When deciding what to work on, choose projects with the highest impact.

Earn trust

We make to maximize the trust of others in our judgments. We are open, self-critical, and factual.

Our Location

We are a remote-first company. While we are headquartered in Palo Alto, California, you’ll find the Mattermost team all over the world!
