Course-platform builder, Lisbon. Users request everything (forums! certificates! AI! blockchain! one asked for blockchain, in 2026). Saying no without losing love: the script.
"No, and here is why" (one sentence, the real reason, not "we'll consider it"). "Yes, if" (the condition that would change it: "if 20 teachers need it this quarter"). "Not now, instead" (the adjacent thing shipping that covers 80%). Logged publicly (the request board shows all three answers; no black hole; black holes breed resentment).
Result: feature-request volume steady, complaint volume down 60%, and three "no"s became beloved "yes, if"s that shipped later with parades. No is a feature. Documented no is a beloved feature.
