Validation kills vanity assumptions before they consume engineering cycles. Today, this phase moves faster than ever. Vibe coding, conversational prototyping, and AI-native mockups let PMs ship rough but functional surfaces in hours, not weeks. Run fake-door tests, measure Time-to-First-Value on prototypes, and track early engagement telemetry. If users don’t return after the first interaction, the hypothesis is wrong. Pivot or prune. The goal isn’t to prove you’re right. It’s to learn cheaply before the runway tightens. [Research: Eric Ries, The Lean Startup; modern AI prototyping velocity studies, 2023—2025].
