Jely: Send video or photo to LED billboard

Hey Product Hunt 👋 I'm Paulo. Before this, my cofounder Rodrigo and I built Filtrify (ad tech for small merchants in Brazil. 24,000 of them, R$158M in payment volume, eventually sold to a marketing group). We learned one thing well: selling something cheap to a lot of people is a completely different business from selling something expensive to a few. Then I got interested in the LED billboard above a pizzeria in Araçatuba, a city of 208,000 in the Brazilian countryside. It runs a loop of 30 slots, 10 seconds each, one every 5 minutes, 18 hours a day. Most of those slots are the same six advertisers on repeat not because the billboard is full, but because selling a $6 slot costs more than it earns. So nobody sells it. We bought one slot and started reselling it by the minute. You pick an exact time, upload an image from your phone, pay R$30 (~$6). It plays three times inside a 15-minute window. Then a screenshot pulled from the billboard's own playout system lands in your WhatsApp as proof it actually aired. Our cost per play is about one cent. That asymmetry is the entire business. Honest state of things: one billboard, one city, R$3k invested so far. Every image is approved by a human before it goes up, so if you upload at 3am Brazil time it'll sit in a queue until someone wakes up. We got our first organic sale a few days ago someone found us and bought without us pushing anything at all, which is the only number I've cared about for months. What would you put on it? Genuinely asking. The answers decide what we build next.
