What does Cofounder do?

Cofounder is an agent orchestration platform that lets you run an entire company with AI. You start by giving it your product idea or existing product, and it builds out an AI roadmap covering engineering, sales, marketing, design, finance, and operations. Instead of managing a dozen tools and hiring a team, you hand off entire departments to AI agents that work together under a shared company context. The platform is designed to feel like a real company — with departments, managers, and a central operating system that keeps everything aligned.

What makes Cofounder stand out is its structured approach. It breaks down company-building into three phases: Launch (1.0), Grow (2.0), and Operate (3.0). In the Launch phase, it helps with business positioning, brand identity, marketing website, and launch content. The Grow phase handles customer research, prospect discovery, email outreach, and marketing newsletters. The Operate phase covers LLC incorporation, product analytics, customer support, and recurring workflows. Agents work alongside you and require approval for potentially dangerous actions like opening a bank account or buying a domain. The system is fully extensible — you can connect custom APIs, MCP, custom skills, or even an entire codebase.

Cofounder is best suited for solo founders, early-stage startups, and small business owners who want to move fast without a large team. If you have a product but no time for marketing, sales, or operations, Cofounder can take over those functions. It's also useful for experienced entrepreneurs who want to automate repetitive company tasks while keeping control. Over 10,650 companies are already using it, and the platform includes case studies from companies like ActiveGraph, Veery, LearnPath, and Valence OS.
