How do the very best companies use pricing itself as the growth engine rather than a checkout screen?

They pick a value metric that grows on its own as the customer succeeds, then price against it, so revenue expands without anyone selling anything. GitHub charges as teams add developers, Shopify takes a cut of what merchants sell, Intercom prices AI support per resolution. The common thread is that the customer never feels a price increase, only their own growth. Almost nobody does pure usage-based any more, and the current best practice is a hybrid: a predictable subscription floor so finance can budget, plus a consumption component so the ceiling moves. The failure mode to avoid is picking a metric that is easy for you to measure but meaningless to the customer, like API calls, since nobody can forecast their bill and the anxiety kills expansion.
