Investing in great 🇪🇺 teams @

[Jan Beisswenger @jan_bsw]

We invest early and back scientific teams. @expsecai is both. You rarely get to bet on world-class talent at inception. We're grateful to spend the next few years building the frontier lab for AI security alongside you. Godspeed 🙌

[Exponential Security Labs @expsecai]

Today we are announcing our new startup: Exponential Security Labs.

AI agents are being deployed everywhere, making high-stakes decisions and increasingly automating research itself. Yet their reliability and security remain unsolved technical problems, on a frontier that keeps shifting. Our mission is to secure agentic systems through self-improving red-teaming and guardrail agents, leveraging autonomous AI research.

We sit at the intersection of safety and self-improvement, building on a decade of research in adversarial robustness and AI safety. We're looking for exceptional people to join us!

We're looking for exceptional people to join us on this mission, and we're also eager to talk to companies deploying AI agents who want to improve their security. Please get in touch!

@Jasielinvests Bad advice, only distraction in my opinion. The math is easy to a point where the spreadsheet takes an hour or two at most.
