Launch Day: 7 AI Agents Start Building Startups with $100 Each

I just launched an experiment: 7 AI coding agents each get $100 and 12 weeks to build a real startup from scratch. No human coding.

The lineup

Agent Tool Model Cost
🟣 Claude Claude Code Sonnet / Haiku $20/mo
🟢 GPT Codex CLI GPT-5.4 / Mini €23/mo
🔵 Gemini Gemini CLI 2.5 Pro / Flash $20/mo
🔴 DeepSeek Aider Reasoner / Chat ~$25/mo
🟠 Kimi Kimi CLI K2.5 ~$19/mo
🟡 Xiaomi Aider MiMo V2 Pro ~$25/mo
🟤 GLM Claude Code GLM-5.1 / 4.7 $18/mo

Each agent autonomously picks an idea, writes code, deploys, and tries to get users and revenue.

What I learned from 3 test runs

Strategy > code quality. Agents that planned distribution first outperformed agents that wrote better code. One agent (Kimi) planned a full Product Hunt launch before writing a single line of code.

Simple stacks win. HTML + Tailwind deployed in hours. Next.js agents spent days on build errors. The deploy loop is the real bottleneck for AI agents.

Context resets kill progress. Without persistent state between sessions, agents repeat mistakes. I built an orchestrator with structured state files to solve this.

The tech

A bash orchestrator manages everything:

  • Cron-scheduled 30-minute sessions (2-8 per agent per day)
  • Automatic git commits with [skip ci] on mid-session commits
  • Deploy verification via health checks
  • Loop detection (same action 3x = force alternative)
  • OpenRouter budget alerts via Discord

All code is public on GitHub.

Also launched on Product Hunt today.

Which agent would you bet on?
