How to Build Your Startup with CoFounder.im and OpenClaw

Go from startup idea to working code autonomously. Learn how to use CoFounder.im's AI cofounder to validate your idea, generate a build spec, and have OpenClaw's multi-agent system build it for you.

1

Validate Your Idea with AI Agents

Start by describing your startup idea on CoFounder.im. Our 15+ AI agents will analyze it from every angle — market research, competitor analysis, technical feasibility, business model, and more. This produces the foundational documents that OpenClaw will use to build your project.

Pro Tip
The more detailed your idea description, the better your build spec will be. Include target audience, key features, and revenue model.

2

Review Your Agent Outputs

Once all agents complete, review the outputs: market research with TAM/SAM/SOM, competitor analysis, tech stack recommendations, MVP feature plan, UI/UX design system, and implementation plan. These form the foundation of your build specification.

Pro Tip
Pay special attention to the Tech Stack and MVP Planner outputs — these directly influence what OpenClaw builds.

3

Generate Your OpenClaw Build Spec

The OpenClaw Builder agent automatically transforms all your agent outputs into a structured multi-agent build specification. This defines sub-agent tasks, supervision plans, and build phases that OpenClaw's autonomous system can execute.

Pro Tip
Wait for the OpenClaw Builder agent to complete before connecting to OpenClaw. This is the bridge between ideation and execution.

4

Set Up Your API Token

Go to your Account Settings on CoFounder.im and generate an API token (starts with 'cfr_'). This token authenticates OpenClaw's access to your project's build specification via our REST API.

Pro Tip
Keep your API token secure. You can regenerate it anytime from Settings if compromised.
5

Install and Configure the CoFounder Skill

Install the CoFounder.im skill in OpenClaw by running 'npx clawhub install cofounder-im', then configure your token with 'openclaw config set skills.entries.cofounder-im.env.COFOUNDER_API_TOKEN YOUR_TOKEN'. Restart your OpenClaw gateway to activate.

Pro Tip
You can also use our MCP server with any MCP-compatible agent (Claude Code, Cursor, Windsurf) — not just OpenClaw.
6

Let OpenClaw Build Autonomously

Ask OpenClaw to pull your build spec and start building. It will spawn coordinated sub-agents that execute the multi-phase development plan — from project scaffolding to feature implementation and testing. Monitor progress and iterate as needed.

Pro Tip
Start with a smaller scope if your project is complex. You can always run additional build phases to add features incrementally.
