CopyMortem: Landing Page Headline Graveyard & Winning Variant Archive for Indie SaaS

The Problem

Indie SaaS founders on r/indiehackers and HN repeatedly A/B test their landing page headlines but store results nowhere structured — winning copy gets lost in Notion, losing variants are forgotten, and the same bad headlines get retested months later. CopyMortem is a lightweight vault where founders log every headline, subheadline, and CTA variant they've ever tested, tag it with the traffic source and conversion rate, and get a visual diff showing what changed between their worst and best performers. The app surfaces pattern insights like 'pain-forward headlines outperform feature-forward 3:1 for your audience' as the archive grows.

Target Audience

Solo SaaS founders and indie makers who run their own landing page copy experiments without a dedicated marketing team

Monetization Angle

$8/mo solo plan; $24/mo team plan with shared workspace; potential one-time export for founders selling their SaaS

Recommended Tech Stack

Why Now

The explosion of no-code landing page tools (Framer, Webflow) has made it trivially easy to swap copy, creating a testing culture but zero institutional memory for the results.

MVP Scope

Log a headline + conversion rate + date → tag it with traffic source → view a sorted leaderboard of your best performers → export as CSV.

AI Angle

AI optionally analyzes the graveyard and identifies linguistic patterns (length, emotional trigger words, specificity level) that correlate with the founder's personal conversion wins.

Primary Risk

The core value compounds only after 10+ logged variants, so early users may churn before they see the pattern-recognition payoff.

Validation Checklist

• Post 'Where do you store your failed landing page copy variants?' in r/indiehackers and count how many say 'nowhere' or 'a random doc'
• Audit 10 popular SaaS landing page teardown threads on X to confirm founders lack a structured logging habit
• Build a public 'Headline Graveyard' showcase page featuring anonymized real SaaS test results and measure organic sharing
• Offer 5 indie founders a free manual audit where you organize their scattered copy tests to validate the pain is real and recurring

Who Would Pay For This

Likely buyers are people already trying to solve this problem with manual workarounds. Start with Solo SaaS founders and indie makers who run their own landing page copy experiments without a dedicated marketing team and validate urgency before adding secondary features.
