About basecamp

Basecamp is a project management and team collaboration platform created by 37signals. It centralizes to-do lists, message boards, file storage, group chat (Campfire), and scheduling in a single project space. It is designed around asynchronous communication and flat team structures, making it popular with remote teams, agencies, and small businesses. Unlike most project tools, paid plans do not gate features by tier. The latest version (BC5) was released in 2026.
