PALO ALTO, CA, Feb. 5, 2019 (GlobeNewsWire) — Mattermost, the fastest growing messaging platform for engineering teams at large organizations, today announced that it has closed a $20 million series A funding round led by Redpoint Ventures with participation by S28 Capital and Y Combinator.

Hi everyone, I am excited to announce that Mattermost has raised a $20 million Series A round led by Redpoint Ventures, with participation from S28 Capital and Y Combinator. Mattermost’s mission is to make the world safer and more productive through open source software.

Bugs are dumb. They’re also inevitable. However annoying that may be, it’s more productive to accept the existence of bugs in our workflows than to panic-spiral every single time they pop up. Part of the acceptance process is keeping bugs (or at least the ones you care to fix) top of mind by paralleling your error monitoring and your sprint planning.

After closing a $20 million Series A round, Mattermost is skyrocketing in popularity as a secure, open source Slack alternative for enterprise DevOps and IT. High-trust teams are adopting it for messaging to overcome some of the biggest collaboration challenges today.

We are releasing a recommended security update via Mattermost Team Edition 5.7.1, 5.6.4, 5.5.3 and 4.10.6 (ESR) and Mattermost Enterprise Edition 5.7.1, 5.6.4, 5.5.3 and 4.10.6 (ESR). This security update addresses a high-level vulnerability discovered during a security research review by Rohitesh Gupta.
