Wouldn’t want to do it again without the Entrée team. Special shout out to @saullevin who is an absolute powerhouse.
Welcome to the portfolio, @UltraSecurityHQ! 🎉
AI agents act on their own across company tools. Ultra gives security teams real-time visibility and control over every prompt, data pull and tool call.
Out of stealth with a $10M seed. Proud to back it. Congrats Chase Lee and team!
We're hearing from teams of every size, from startups a few weeks into deploying agents, to Fortune 500 companies managing thousands of them. The common thread is that agents are being deployed faster than they can be secured. That's the problem we're solving, and we're excited to keep building.

Hello World 👋
Ultra Security is out of stealth with $10M in seed funding to secure autonomous systems.
Ultra puts enforceable boundaries around autonomous systems without slowing down the work they're built to do. We've built guardrails, governance, observability, and anomaly detection in one platform.
Agents aren't predictable. Security should be.
Thank you to @LudlowVentures, @hiddencap, @EntreeCapitalVC, @dvpfund, @pinverrr, @forward_deploy, our angels, and the design partners who have supported and helped us build Ultra.
