Case Study: Classact accelerates incident response by 50% with Mattermost

Classact speeds up IT service delivery by consolidating communication, accelerating incident response by over 50%

Classact, a Tokyo-based IT consultancy with 150 employees working across client sites and home offices, struggled to keep communication organized across email, phone, SMS, and an underused custom chat tool. The patchwork setup caused delays, missed messages, misunderstandings, and extra maintenance work, while the company also needed stronger data security and Active Directory integration to support ISO 27001 goals.

Classact chose Mattermost’s self-hosted collaboration platform to centralize communication and secure team coordination. With Mattermost, the company accelerated incident response by more than 50%, cut problem-solving time to less than half of what it was before, and improved real-time collaboration across 170 monthly active users. Mattermost also became a broader operations hub, supporting integrations for alerts, reporting, access control, training, and employee health management.
