Most 0 to 1 products begin with a simple, tightly scoped objective. You solve a problem. You unblock a workflow. You automate something repetitive. You launch a feature that makes life easier for one team or a few customers. But the products that eventually transform an organization do not remain confined to that first use case. They grow. They expand. They mature into platforms. And when they become platforms, they stop being a tool. They become the foundation that enables everything else to scale.
