Inverte o Jogo

I built an AI sticker generator for the 2026 World Cup. Upload a photo, pay, and get a personalized sticker by email — shipped in a few days as a real MVP.

I started making stickers for friends with ChatGPT and realized it could be a product. Wanted to validate the idea fast, not overbuild a platform.
