A small startup buy-and-sell marketplace built in 8 hours, iterated on user demand, pushed to nearly $20K MRR on a 3% deal fee plus paid featured listings
It went from a startup leaderboard to an acquisition marketplace: projects get listed and sold every single day, a small project doing $1K/mo sells for $30-35K, and the platform takes 3% — while the site itself was "written in 8 hours" and then extended purely on what users asked for.

[Video] Indie developer Marc Lou (also behind DataFast) walks through TrustMRR: it started as a startup leaderboard, and only because users wanted to "sell my project on the platform" did he add an acquisition marketplace, turning a leaderboard into a brokerage for buying and selling startups. Within four weeks 1,000 startups were listed for sale, projects get acquired every day, and traffic runs roughly 5,000-6,000 visitors a day. He also mentions turning down a $1M offer to acquire TrustMRR.
The cold start was solved before the marketplace existed, because the site was a leaderboard first: the startups were already listed, ranked and indexed, so the only new thing anyone had to do was flag a project as for sale.

Money started roughly 48 hours after the monetisation feature went live. The fee is 3% of each closed deal, and the first to land was a $100,000 acquisition that had already reached escrow with the letter of intent and the asset purchase agreement signed, worth $3,000 to the platform.
Three things compound here. The first is that every closed sale advertises the next one: a startup is acquired on the platform every day, and a seller who has just turned a $1,000-a-month project into $30,000 tells people, because selling a company changes how everyone around you looks at you.
There was no long silence here, because the thing that became a business began as something else. The whole site was about eight hours of code and lived as a startup leaderboard until someone asked to sell their project on it.
