Technical founder here. Built a B2B SaaS (findforce.io - business email finder) for 2 months. Clean architecture, 95% accuracy, competitive pricing. Zero customers, zero revenue.

Key lessons: - Distribution beats product quality - PMF isn't negotiable (perfect tech + no demand = failure) - Customer interviews are the actual work, not optional homework - Audience-first approach matters more than I understood

Also became a father this year (never wanted kids). Interesting contrast: failed at what I planned for, succeeded at what I didn't.

Pivoting to audience-first for next attempt. Curious if others have similar experiences with first product failures and what you did differently the second time.
