Niche directory with paid ad slots

Build a list people already want and sell labeled sponsor slots. Audience, not the code, is the constraint.

Evidence: A.

TrustMRR's own page shows $23,984 MRR verified with a Stripe API key (TrustMRR, checked Oct 15, 2026).
Marc Lou says it took 6 hours to build, and the ad spots sold out within 3 days at $299 to $1,499/month (newsletter). That part is self-reported.
He had a large X audience; his launch post reached 2.9M views.

Difficulty: 3/5

Steps

Find a list people want but nobody maintains, ideally one tied to a live conversation on X.
Build the MVP in a day with an AI coding agent. Include search, filters and submissions.
Add 3–6 clearly labelled sponsor slots with a Stripe Payment Link. Start low and raise prices as traffic grows.
Launch with a thread that shows the data.
Add features that create return visits: leaderboards, embeds, weekly email.

Pitfalls

No distribution means no sponsors.
Stale data kills trust.

Agentic Paycheck does not guarantee income, revenue, profit, or employment. Dollar figures are quoted from the named sources. Self-reported claims are labeled self-reported. Independently documented claims describe someone else's result, not a forecast for you. When a source did not give a cost, the entry says it was not disclosed. Sponsored placements, if any, are labeled and do not change evidence grades.
