ABOUT AIUC

AIUC builds standards and insurance for frontier AI. Our mission is to Underwrite superintelligence https://underwriting-superintelligence.com/. We exist because risk, not capability, is becoming the binding constraint on AI being useful. History offers lessons for how to build confidence in new technology; electricity burned down houses until insurers funded Underwriters Laboratories (UL) to certify products against their standards. Today, the UL mark is a trustmark on every light bulb in America. We’re building that for AI.

AIUC-1, our standard for agent security, serves frontier builders like Cursor, Lovable, ElevenLabs, and Harvey. We've raised $55m from Ribbit, First Harmonic and Nat Friedman to audit frontier AI. Our team comes from METR, Anthropic, McKinsey, and OpenAI. Come join us.

You’ll be our first security hire, joining as we open our product to the world, while our own agents test other companies’ agents. You’ll own security end to end across our product, evaluation platform, and internal systems, and work directly with the founders. You’ll take on agent security problems nobody has solved, prove the answers on our own systems, and watch them become the playbook other companies follo
