A/B testing tool for YouTube thumbnails that helps creators find which image drives more clicks, built before YouTube shipped the feature natively.
Guillaume "Rox" Pacheco built ThumbnailTest after working briefly with the MrBeast team and seeing firsthand how critical thumbnail performance is for top creators. He grew the product to $20,000 MRR. In early 2024, he sold for a six-figure sum, just 4 months before YouTube launched its own native thumbnail testing feature. Rox was publicly conflicted about the sale but credited creator community credibility as the main moat.
From founding to sale took 1.5 years. Time to exit is a useful signal of how built-to-sell a business was, faster, cleaner processes usually mean better-documented operations and fewer diligence surprises.

If you are building a tool that patches a missing platform feature, exit before that platform ships it themselves. Distribution and creator community credibility can be a stronger moat than the tech.
