Securing the future of AI

Ultra was founded in 2025 by Chase Lee, founder of Trustpage and later VP of Product at Vanta, where he was building AI security products. He started Ultra with a team of security and compliance professionals, machine learning researchers, and engineers who saw the same gap opening in the AI agent ecosystem.

The teams adopting agents fastest were all hitting the same wall. Their AI clients were powerful but opaque: when Claude Desktop or Cursor called a tool, nobody could say exactly what had happened. As the Model Context Protocol (MCP) let agents reach tools, APIs, and sensitive systems, tool poisoning, context injection, and uncontrolled MCP sprawl became real threats. Security teams had no answer to the question that matters most in a regulated environment: what did the agent do, what data did it touch, and how?

None of those threats show up in a code review, because none of them exist until the system is running. A tool description changes after you approved it. A poisoned result comes back mid-session and the agent acts on it. A new connector quietly widens what every agent can reach. Agents and MCP meet at runtime, and that is where the risk lives.

So we built Ultra to secure the runtime: real-time monitoring of agent behavior, protection against attacks that exploit agent-tool trust, and full visibility across your MCP infrastructure. That is what we mean by autonomous runtime security, real-time visibility and enforcement for systems that act on their own. We envision a future where agents are present in our homes, on every device, and inside the systems that run daily life. We are building for that world, because a more autonomous future is only a safe one if something secures it at the moment agents act.

Ultra is backed by more than $10M in seed funding from Ludlow Ventures, Entrée Capital, Detroit Venture Partners, Firedrop, Hidden Capital, and FDVC, with angels from Vanta, Secureframe, and the broader security community.
