Fable

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.

Your Role

You will work on the team that owns our data platform, including real-time API integrations, Kafka-based streaming systems, Spark and Airflow data pipelines, and the data services that power our application layer. You take pride in building reliable, maintainable, and scalable infrastructure that turns complex data flows into high-quality services for the product. You can translate product and customer requirements into durable platform designs, make thoughtful technical tradeoffs, and build systems that anticipate our needs as we evolve.

Fable is founded by the early team from Abnormal Security ($5B valuation) and backed by Greylock, the investors behind Palo Alto Networks, Okta, Figma, and others. Our team has built many of the iconic products at Meta, Twitter, Flexport, and more. Our team has alumni from Waterloo, Columbia, Berkeley, Purdue, CMU, Stanford, and USC.

How We Work
  • We work from our San Francisco office three days a week , fostering collaboration and deep focus.
  • We emphasize mutual trust, high execution, and delivering differentiated product experiences .
