AI-driven threats and human error are today’s biggest enterprise security risks. Cybercriminals don’t hack systems — they exploit people. Human errors drive 70% of security breaches, making human behavior the primary and growing attack surface.
At Fable, we believe the right tools can convert people from targets into another layer of defense.
Fable is the human risk platform that directly shapes employee behavior. Designed for simplicity and enterprise scale, our agentic platform synthesizes complex employee data, pinpoints risky behaviors, and deploys highly relevant interventions to people automatically, in real time, right where they work.
Backed by Redpoint Ventures and Greylock Partners and founded by early Abnormal Security team members, Fable is solving cybersecurity’s biggest challenge in a multi-billion-dollar market. Our team includes alumni from Meta, Twitter, Flexport, and top-tier universities like Waterloo, Columbia, Berkeley, Purdue, CMU, Stanford, UCLA, and USC.
We are experiencing explosive growth, making this a career-defining opportunity to join and shape the future of security.
