# BizBuilder

> The AI Copilot for vibecoders. Builders should stay builders — we do the labor of being found. Paste your URL. We run a free Probe — a real micro-test that finds your first customers and shows them arriving in your city within hours. Like what you see? The Engine keeps growing it for $79/month — from first URL to first revenue to scaled business.

BizBuilder is the AI growth copilot for solo founders who shipped on Lovable, Cursor, Bolt, v0, or Replit and have zero users. We run the customer-acquisition loop end-to-end (hypothesis → test → measure → diagnose → execute → re-test) on real ad platforms (Bing, Google, X, Reddit) until traffic converts or we tell you honestly it won't.

## How it works

- [Paste your URL](https://bizbuilderai.com/) — paste your live app URL.
- [Probe](https://bizbuilderai.com/llms-full.txt#probe) — AI reads the page and proposes 2-3 audience-archetype districts, then runs a real, hard-capped (~$10-15) micro-test across them. Free. No card asked.
- [City census](https://bizbuilderai.com/llms-full.txt#census) — within hours you watch real strangers arrive as dots in your city. Bustling, trickling, or empty districts ARE the Kill / Pivot / Double-Down Reading — no opinion, just live data.
- [Engine](https://bizbuilderai.com/llms-full.txt#engine) — if a district lights up, subscribe to the continuous Engine at $79/month to keep growing what worked.

## For agents and tools

- [agent.md](https://bizbuilderai.com/agent.md) — machine-readable spec of what an agent can do with BizBuilder.
- [llms-full.txt](https://bizbuilderai.com/llms-full.txt) — long-form context: pricing, ICP, FAQ, lifecycle ladder.
- MCP server: in-progress for Cursor, Claude Code, Lovable, Bolt. See agent.md for the planned tool surface.

## Pricing

- The first Probe is free — a real micro-test, not a trial. No card asked.
- The Engine is a flat $79/month, month-to-month, cancel anytime. Optional annual: $790/year.
- Founders fund their own ad media — passed through to the ad platforms at cost, with zero markup.
- No success fees. No revenue share. We never take a cut of your sales.

## What BizBuilder is not

- Not a marketing-agency replacement. We own the LOOP, not the outcome.
- Not an AI-generated reports generator. Every Probe launches real paid ads on real platforms.
- Not a click-fraud farm. We surface honest Readings including "this is structural, not distributional."
