Cofounder

CoFounder.im is a web-based startup planning and validation tool that uses a swarm of AI agents to turn raw ideas into structured, investor-ready outputs. You describe your startup concept in natural language, and the system runs 20+ specialized agents in parallel to analyze it from multiple angles. According to their site, this process typically takes around 12 minutes and produces 20+ reports plus a pitch deck you can tailor and share with cofounders or investors.

The product is aimed at aspiring and early-stage founders, as well as non-technical or first-time entrepreneurs who need help with market research, competitor analysis, and business modeling. You sign up with email or Google, receive an initial bundle of free credits, then choose a subscription tier that determines how many projects you can run each month. Everything runs in the browser; no coding or technical setup is required.

CoFounder.im leans heavily into an agentic approach: once you submit your idea, a coordinated swarm of AI agents runs autonomously to generate comprehensive documentation, including reports and pitch materials. This makes it useful if you want fast, structured feedback and ready-to-edit documents rather than a back-and-forth chat. However, the site doesn’t detail which underlying AI models are used, how data is stored, or specific privacy guarantees, so teams with strict compliance requirements may need to reach out for clarification.

The credit and subscription system is straightforward, with clear limits on how many project ideas you can process per month and the option to buy additional credits that do not expire. Users without a subscription are capped at a small number of total projects, so this isn’t a long-term free tool. It’s also not a general-purpose AI assistant: it’s narrowly focused on startup and business planning, not coding help, generic writing, or broad workflow automation. If you need deep customization of the agents themselves, integrations into your internal systems, or guaranteed enterprise-grade controls, those capabilities are not evident from the public pages.
