Vybe Raises $10M for Agent Runtime

In December 2025, the AI infrastructure startup Vybe emerged from stealth with $10 million in Seed funding. The round was led by Innovation Endeavors, with participation from Stellation Capital and notable angels including Nat Friedman.

The company is founded by Mitchell Hashimoto, the legendary creator of HashiCorp (Terraform, Vault). After defining the cloud infrastructure era, Hashimoto has returned to build the foundational runtime for the autonomous age.

Vybe describes itself as an “Operating System for Agents.” Currently, running AI agents is brittle; developers struggle with sandboxing, state management, and letting agents safely execute code without destroying production environments. Vybe addresses this by providing a secure, isolated “Agent Runtime”—a controlled environment where agents can spin up, execute tasks, and spin down efficiently. It aims to solve the execution layer problem, much like how Terraform solved infrastructure provisioning for the cloud.

The new capital will be used to build out the core engineering team and release the first public version of its agent execution platform.

Market Signal

• The “HashiCorp” Effect: Mitchell Hashimoto entering the arena is a massive signal. It suggests that “Agentic AI” has moved past the “toy demo” phase and now requires serious, enterprise-grade tooling. Just as he standardized Cloud (Terraform) and Security (Vault), the market expects Vybe to standardize Agent Execution.
• Safety as Infrastructure: The biggest blocker for Enterprise Agents is safety (e.g., “What if the agent deletes the wrong database?”). Vybe’s focus on a “sandboxed Runtime” shifts safety from a prompt engineering problem to an infrastructure guarantee, which is exactly what CISOs are waiting for.
• Defining the “Runtime” Layer: While players like Runware handle the Inference (Thinking) and LangChain handles the Orchestration (Planning), Vybe is carving out the Runtime (Doing). This creates a clear separation of concerns in the modern AI stack.
