A note from the founder

I've spent too long watching good videos quietly miss their audience — not because the content was wrong, but because nobody tested the thumbnail.

The first idea is almost never the best one. You don't know which one is until real viewers vote with their clicks. Every other testing tool I tried felt like it was built around YouTube's limits instead of around the creator.

So I'm building SplitFrame: rotate your real thumbnails on your real video, measure real CTR with real statistics, and let the data — not your gut, not an "expert" — pick the winner.

The first 500 founding members get their first month of Pro free, early access, and a direct line to me while we shape it. Hit reply to any email — every one lands in my inbox, and I answer them myself.

Thanks for being here early.
