What I learned launching a simple ad marketplace in 24 hours

Two days ago I launched TabRush.

It’s a very simple idea: One Safari tab becomes a mini billboard.

After launch, I got 4 sales in less than 24 hours.

This is what surprised me: - Simplicity wins. The landing page is very minimal. - Pricing psychology matters. Every purchase increases the price. - Marketing is 80%. Building was fast. Distribution was harder.

I shared on Reddit, Hacker News and X. The feedback helped more than I expected.

If I do it again: - I would focus even more on storytelling.

I’m sharing this because many indie makers overthink. Sometimes small and fun ideas work.
