Three founders, one app, and the loudest proof yet that you can build software just by talking.
Three guys. One app. Your voice does the building.
We're Big Business Guys — three founders documenting the build of Rally, the voice-first tool that turns talking into real, working software on Claude Code. No laptop, no syntax. Just an idea, out loud, on its way to the world. Follow along on TikTok and Instagram.

Why we're all in on this
Your voice is the keyboard
Describe the app you want out loud and watch it take shape. There's no syntax to memorize and no laptop to lug — if you can explain it, Rally can build it.
Ship from anywhere
Rally lives on your phone, so the idea you have on a walk doesn't have to wait for a desk. Open the app, talk it through, and push a real change before the light turns green.
Claude Code under the hood
It's not a toy demo. Behind every command is Claude Code actually writing, editing, and wiring up software — you bring the vision and the voice, the agent handles the engineering.
Our story
About Big Business Guys
We're three founders who got tired of good ideas dying in the notes app. So we picked up Rally — a voice-first tool that builds real software from your phone using Claude Code — and started building out loud, on camera, for anyone watching on TikTok and Instagram.
Big Business Guys is the brand around that build. Part build log, part proof of concept, part three guys betting that the next great app gets made by talking, not typing. Stick around — we're taking this thing to the world.

Add a second genuine line as the build picks up. Even one honest reaction beats a wall of claims — paste it here when you have it.
An early tester
One more spot for a real quote — a creator who tried it, a friend who got hooked. Replace this with their voice the moment you've got it.
