Paulina Xu is Co-Founder and CEO of Agentic Fabriq (YC W26), the identity, governance, and visibility layer built specifically for AI agents operating in enterprise environments.

Paulina was studying AI and Physics at MIT, conducting CS and ML research at MIT Kavli Institute, MIT Haystack Observatory, and INAF Padua before dropping out to build Agentic Fabriq.

Paulina recognized a critical gap in enterprise AI: identity systems were designed for humans, not autonomous agents, and set out to build the missing security middleware for the agentic era.

Agentic Fabriq is a YC W26 company backed by Y Combinator with $500K raised at Pre-Seed stage, positioning itself as the Okta for AI agents with a single control plane for auth, permissions, and audit logging.

Agentic Fabriq enables enterprises to enforce least-privilege access and fine-grained per-user permissioning across all AI agents, centrally logging every action for audit and compliance at scale.
