About

3 weeks ago, I left my startup to find a new challenge. Having built a cracked team of 15+ top performers, it's time I return to my true passion; building and scaling from the ground up.

I've been coding and building from the day my parents bought me my first computer when I was 10. I am the youngest person ever to develop and publish a game on Steam at age 17.

I'm fiercely competitive, dedicated, and determined to help launch a new rocket 🚀

Manifesto

2025 is the year small teams reclaim capitalism. Not with theory or pitch decks, but with shipped code and real revenue.

Startups used to be bloated. Too many people, too much talk. Now, with generative AI, four people can do what it used to take forty to fake. The barrier to trying something real is basically gone. The cost of building has collapsed. What's left is will.

This doesn't mean it's easy. It means there are no excuses. The market is brutally honest. If it wants what you've built, it pays. If not, you'll know fast. That's the beauty of it: no more waiting around to be picked. You pick yourself. You put something in the world and the market tells you what it's worth.

This is capitalism distilled. Not the fantasy version. The real thing. No gatekeepers. No middlemen. No innovation theater. Just product, price, and demand. The signal is pure, if you're willing to listen.

We've got 12 weeks. Not to guess, but to test. Not to debate, but to ship. This isn't school. There's no prize for effort. The only thing that matters is whether it works.

We're not here to play startup. We're here to sell something. To trade ideas for value. To see if the future wants what we've made.

Let's ship something extraordinary, or fail fast trying.
