Profile
Substrate provides a personal AI computer, Zo, that runs in a user's private cloud to automate tasks, build websites, and integrate with various tools.
Substrate, founded in 2023 and headquartered in the United States, operates as a personal AI computer platform under the brand Zo. The company was created by co-founders Rob, the first engineer at Substack, and Ben, an early engineer at Stripe, and is backed by investors including the Collison brothers (Stripe), Guillermo Rauch (Vercel), and others. Substrate's flagship product, Zo, is an always-on AI agent that runs in a user's personal cloud, capable of building websites, running automations, connecting to external tools, and managing files.
The platform is accessible via text, Slack, email, Discord, Telegram, and a web browser, and includes built-in storage, compute, and networking. Zo is free to try with a daily usage allowance, and users can purchase credits for additional access to AI models or bring their own API keys. Substrate emphasizes data privacy, stating it will not sell user data, allow advertising, or train AI on user work, and positions Zo as a departure from centralized SaaS models.
The company's mission is to enable universal access to cloud computing, aiming to 'rewild the internet.' As of mid-2025, Substrate had not disclosed revenue or headcount publicly, but its investor list and the launch of Zo in June 2025 indicate early-stage traction. The company faces a competitive landscape with other AI agent platforms like OpenClaw and Hermes, which it claims to have inspired. No recent funding rounds or financial results were found in the provided dossier beyond the initial backing.
