I ship apps that make money. & I'm going to show you how.

I'm David — 20, based in Miami, running BeSure AI and a small studio of apps with my partner Mateo. Every week I send one email: what I built, what shipped, what actually moved revenue.

For builders who want to ship

The playbooks I actually use. The exact funnels, hooks, and pricing tests behind BeSure AI.
Growth that worked (and didn't). Creator deals, paid tests, ASO wins — with the numbers.
Stack & shortcuts. Tools, prompts, and workflows I'd give my little brother.
Behind the builds. New apps we're launching under NXONDEVS, live.
