We Don't Sell You

One of 37signals' numbered manifesto pages — a short statement that compresses the company's business model into a single principle: they sell software to customers, not customers to advertisers. The distinction is small on the page and structural underneath; it determines the incentives, the product design, the relationship to users. For product direction the page is useful as a diagnostic — almost every product decision descends from the answer to "who is our customer, really?", and 37signals makes the answer loud on purpose. Share it in conversations about ad models, alignment, and what it takes to build a product that is honestly aligned with the people who use it. A one-minute read; keep it as a conversation opener.
