Field notes (read these before you build)

Unexpected challenge: friends will praise the idea and still refuse to pay. Design tests that cannot be passed with politeness.

Counter-intuitive advice: ship fewer pages and more commitments. A waitlist is weak; a scheduled pilot with a date is strong.

Distribution bottleneck: warm intros dry up. Build a cold motion that still sounds human—specific problem, specific proof, short ask.

Hidden cost: learning debt—frameworks consumed without experiments create false confidence.

One caution: if metrics only move when you post on social, you have an audience project, not necessarily a company.

One recommendation: open the Idea database, pick three candidates, and disqualify two today using willingness-to-pay evidence—not aesthetics.

Straight take: 2026 is not special enough to justify skipping fundamentals. Models got better; buyers did not start loving vague tools.
