Doppel

Doppel is one of the first a16z/Bessemer-backed cybersecurity names to stand up a real product-building FDE org — proof the model has jumped past AI labs and data platforms into security. The Series C 'social engineering defense' company scans 150B+ entities a day and wants FDEs fluent in OAuth/SAML/SCIM and SIEM/SOAR wiring, not just LLM glue — a reminder that the highest-leverage FDE seats increasingly sit where enterprise identity plumbing meets agentic AI. Two reqs live (SF + remote US), plus an NYC lead track.
