About Fable

AI-driven threats and human error are today’s biggest enterprise security risks. Cybercriminals don’t hack systems—they exploit people. Human errors drive 90% of security breaches, making human behavior the primary and growing attack surface. (ex 1, ex 2, ex 3)

Fable is a security platform that mitigates human risks to the business. We built the first AI-native Human Behavior Platform to eliminate human risk wherever employees work. By leveraging GenAI and behavioral systems, we automatically detect at-risk employees, deliver personalized interventions at critical moments, and remove tangible risks to the business - at scale.

This is a multi-billion-dollar market, and every company—from SMB to Fortune 500 enterprises—is racing to combat this problem. Backed by Greylock Partners and founded by early Abnormal Security team members, Fable has assembled a world-class team to solve this problem. Our team includes alumni from Meta, Twitter, Flexport, and top-tier universities like Waterloo, Columbia, Berkeley, Purdue, CMU, Stanford, and USC. We are experiencing explosive growth, making this an exciting time to join and shape the future of security.
