Chatwork Tech Stack
Business chat platform with task management and video for distributed teams
Chatwork operates a group-chat product used across 206,000+ companies, now building toward AI-assisted workflows and internal process automation. The tech stack reflects a modern frontend-driven architecture (TypeScript, React, Next.js) paired with data infrastructure (Snowflake, dbt, Treasure Data), and active adoption of Claude and GitHub Copilot signals a shift toward embedded AI features. Hiring velocity is accelerating with engineering and product roles dominating the intake, while internal friction around back-office efficiency and low chat adoption in some segments suggests the company is working to move beyond product-market fit toward organizational scaling.
