Trusted by millions, Basecamp is the leading web-based project management and collaboration tool. Basecamp keeps all your projects, data, and people in one place. No matter how many projects you have, or how many people you have working on them, Basecamp keeps everything organized.
Everyone involved in a project can work together on Basecamp. You have full control over who sees which project, and who sees each other. You can also create groups to keep people organized (i.e. a "marketing" or "stakeholders" group). Share any file with your team or client by just dragging it from your desktop right into your web browser. That’s all there is to it. When you keep your files in a Basecamp project, everyone knows where they can find the latest version.
