Leadership Principles

Leadership principles are deliberate choices defining our behavior. When facing complexity, uncertainty, or ambiguity (CUA) we determine our point of view and our actions through the lens of our values:

  • Customer Obsession - We exist to make customers successful. In everything we do, start with customer perspective and work backwards. Earn and keep their trust.
  • Ownership - Own the outcomes of your activity. Don't drop the ball. When we see a vacuum on something important, we jump in--we never say "it's not my job."
  • High Impact - Align work to our shared vision and focus on those priorities. When deciding to work on low impact or high impact projects, choose high impact.
  • Self-Awareness - We understand and seek to understand our strengths and growth opportunities, as individuals and organizations. We are open to critique and share critique constructively and respectfully.
  • Insist on High Standards — Have relentless high standards. Continually raise the bar for high-quality products and processes.
  • Earn Trust — Make decisions based on maximizing the trust of others in your judgement. Earn and keep people's trust.

Mattermost is an open source, remote-first, communities-centered company based in Palo Alto, California and headquartered on the internet.

Open source means that by default we make our technology, business process and source code available to the public. We develop a small portion as proprietary technology, built upon our open source work, to license for subscription fees that enable more high quality open source work to be produced. Since the start of the Mattermost open source project in 2015, we have used this model to develop effective open source solutions for the world to use. This model is sometimes called Thin Open Core.

Remote-first means that the majority of our staff works from home, cottages, coffee shops and other personal areas, rather than at a shared corporate office location. Mattermost was born in an extraordinary age where remote-first organizations can attract, hire and enable remote teams to produce better technology, business process and business results in less time than office-based teams, while maintaining security and compliance standards.

Remote-first culture flourishes when we share one simple principle: Courtesy. Courtesy means Mattermosters are thoughtful about keeping our communities appropriately informed, following etiquette for discussions, calls and video meetings, and giving and receiving feedback on how to work better together. Courtesy also means we gladly accommodate those who prefer to work out of a dedicated office. We are remote-first, not remote-only.

Communities-centered means we define our success in the context of the success of our communities: users, customers, implementers, resellers, technology partners, contributors, and colleagues. The success of each community is owned by a member of the Mattermost leadership team. The plural definition of "communities" is intended to avoid unconsciously marginalizing downstream stakeholders.

Based in Palo Alto, California and headquartered on the internet means the mailing address for Mattermost, Inc. is in Palo Alto, California, and our headquarters is on the internet, specifically the production-quality Mattermost instance at Our online headquarters is where Mattermost staff work with our communities of colleagues, users, partners, customers, candidates, contributors and other community members to envision, develop and refine new open source technologies to make the world safer and more productive.

You can’t perform that action at this time.
