Common questions
What can Co-Founder actually build?
Anything a senior developer can build. Landing pages, SaaS apps, APIs, Stripe integrations, database schemas, CI/CD pipelines, SEO content — it handles the full stack. It also makes strategic decisions: what to build next, how to prioritize, when to pivot.
What's Claude Code and do I need it?
Claude Code is Anthropic's coding agent that powers Co-Founder under the hood. You need it installed and logged in with an Anthropic subscription (Pro, Max, Teams, or Enterprise). Install it from claude.ai — the app will guide you through setup.
Is my code private?
Yes. Co-Founder runs locally on your Mac. Your code never touches our servers. The only external call is to the Claude API (Anthropic), which doesn't train on your data. Your intellectual property stays yours.
How is this different from Cursor or GitHub Copilot?
Copilots wait for instructions. Co-Founder works autonomously — it decides what to build, writes the code, runs tests, deploys, and moves to the next task. It maintains persistent memory across sessions, so session 100 builds on everything from sessions 1–99.
Do I need to know how to code?
No. Co-Founder is designed for non-technical founders. You describe your vision in plain English — 'build a SaaS with Stripe payments and a landing page' — and it handles the technical execution. You focus on customers and strategy.
