NanoCo raises $12 million after viral launch of NanoClaw

NanoCo turned a viral launch into an oversubscribed $12 million seed round, then said no to a roughly $20 million acquisition offer. The move signals how aggressively AI founders are chasing leverage through adoption, betting that a fast-growing user base can outrun an early exit and command far more value later.

Valley Capital Partners led the financing, with Docker, Vercel, Monday.com, Slow Ventures, Clutch Capital, Factorial Capital, and Clem Delangue of Hugging Face joining the round. Gavriel Cohen said the project moved from code written on his couch to a term sheet in under six weeks. That sprint was accelerated by public endorsements from Andrej Karpathy and Vivian Balakrishnan, which helped drive inbound interest from dozens of investors. Cohen said roughly 50 or more founders and tech executives reached out by direct message.

NanoClaw began as a weekend coding project, introduced on Hacker News after a burst of work that also led Gavriel Cohen and his brother, Lazer Cohen, to shut down their AI marketing startup and focus full time on the new company. The product was built as a secure alternative to OpenClaw, with execution isolated in containers rather than running directly on a user’s computer, a design meant to limit the blast radius of prompt injection and misuse.

That security pitch is central to NanoCo’s case for durability. NanoClaw is being positioned as a lightweight professional AI agent that can run locally or on company infrastructure, learn an employee’s role through conversation, and automate work while preserving enterprise controls. Sensitive actions require explicit human approval, and NanoCo has already announced a deal with Docker to integrate Docker Sandboxes into the system. The public repository also says the tool connects with WhatsApp, Telegram, Slack, Discord, Gmail, and other messaging apps while running on Anthropic’s Agents SDK.

The numbers behind the launch help explain the frenzy. In early March, NanoClaw had already drawn about 22,000 GitHub stars, 4,600 forks, and more than 50 contributors. The repository now shows about 29,000 stars, 12.8k forks, and 1,635 commits. That growth gives NanoCo momentum, but the sharper question is whether the company has built a real moat or simply caught the market’s appetite for anything that goes viral. The rejected buyout suggests the founders think the upside is still ahead, and the next test is whether enterprises see NanoClaw as indispensable rather than merely popular.
