Start here

Welcome to 37signals. We're a small software company that builds web-based productivity tools and writes about business, design, and software development.

We believe in keeping things simple, staying small, and focusing on what matters most. These signals represent our core principles and the lessons we've learned over more than two decades in business.

Each signal is a standalone piece, but together they form a coherent philosophy about how to build sustainable, profitable businesses while maintaining your sanity and values.

Start anywhere, but if you're new here, this is as good a place as any.
