The Problem

Indie hackers on r/indiehackers and HN repeatedly ship products that fail quietly — no sales, no signups — but never systematically diagnose why. LaunchPostmortem is a structured self-interview tool that walks founders through a proven failure-analysis framework (pricing, distribution, timing, ICP clarity) and generates a shareable postmortem document plus a 'fix-or-kill' recommendation. The catalog has 36 Business ideas but none address the post-launch failure analysis loop that builders desperately need.

Target Audience

Solo founders and indie hackers who have launched 1-3 products with disappointing results and want to learn systematically before the next attempt

Monetization Angle

Free for one postmortem, $7/mo for unlimited + team sharing + trend data across the community

Why Now

The explosion of AI-assisted vibe-coding has dramatically lowered the cost to ship, meaning more founders than ever are experiencing quiet failures and need a structured way to extract lessons.

MVP Scope

A 15-question guided form that produces a formatted postmortem PDF with an AI-generated 'what likely went wrong' summary.

AI Angle

AI cross-references the founder's answers against common failure patterns from public postmortems (Failory, HN threads) to surface non-obvious blind spots.

Primary Risk

Founders may be too emotionally close to failures to engage honestly, making retention and repeat usage the core distribution risk.

Validation Checklist

  • Post a 'Show HN: I built a structured launch postmortem tool' and measure comment engagement vs. upvotes
  • DM 20 r/indiehackers users who posted 'I shut down my SaaS' threads and offer free access for feedback
  • Check if the Failory newsletter audience would cross-promote in exchange for a revenue share
  • Run a $50 Reddit ad on r/startups targeting 'failed launch' keyword posts and measure signup rate

Who Would Pay For This

Likely buyers are founders, operators, and small teams with a recurring business process. Start with Solo founders and indie hackers who have launched 1-3 products with disappointing results and want to learn systematically before the next attempt and validate whether this can replace a spreadsheet, manual review, or consultant workflow.
