What is Cofounder?

Cofounder is an agent orchestration platform that runs company departments (marketing, sales, finance, design, ops and more) from shared context, with human approval on risky actions. It covers launch, growth and ongoing operations for small teams.

Cofounder is an agent orchestration platform built around a simple premise: a founder should be able to hand off the operational work of a company to AI agents while keeping final approval on every consequential decision. The product is organized like a business rather than a chat window, with distinct departments for strategy, finance, marketing, support, website, operations, design and sales, each staffed by agents that share a common company context. You supply the context (typically the product you have already built), and Cofounder turns it into positioning, brand identity, a marketing site and launch materials that all stay consistent with one story. The workflow moves through three phases. In the launch phase, Cofounder walks a founder from initial idea and company name through connecting product context, filing an LLC, setting up social presence, buying a domain and producing a brand spec. In the growth phase, it researches the market, builds prospect lists from signals like hiring activity, drafts personalized outreach emails, and runs newsletters. In the operate phase, incorporation, product analytics, customer support and recurring workflows are pulled into the same environment so the business keeps moving after launch. It suits solo founders and very small teams who have a working product but no staff to cover go to market and back office functions. The interface mixes user tasks and agent tasks in a single roadmap, and agents working on potentially risky actions pause for human approval before anything ships. Multiple tasks can run in the background at once, and agents can be extended with MCP connections, custom APIs, custom skills, or an entire custom codebase. Cofounder says more than 10,650 companies run on it. Compared with general assistants, Cofounder is narrower and more opinionated: it assumes you want a company built around a product, not a set of isolated prompts. Compared with hiring contractors or stitching together separate marketing, CRM and support tools, it trades depth in any single function for coordination across all of them.
