Doppel builds an AI-driven social engineering defense platform that detects impersonation of brands and executives, takes down attacker infrastructure and trains employees through simulations.
About Doppel
Doppel makes software to counter phishing, impersonation and other social engineering attacks.
The company says its AI agents and a real-time threat graph track threats across channels such as fake websites, social profiles and ads, connect related attacker infrastructure and automate takedowns. Its digital risk protection covers brand and executive impersonation.
A human risk module runs deepfake-driven simulations and awareness training, and newer email security and phishing triage features handle reported messages. Doppel was founded in 2022 in California and originally focused on impersonation scams against crypto firms.
In 2026 it expanded into Japan and reported more than 250 customers.
