Doppel

Doppel (operating via doppel.com) is a premier AI-native social engineering defense platform engineered to protect the world’s best brands from sophisticated, multi-channel attacks. Founded in 2022 and headquartered in San Francisco, California, the company fundamentally transforms how security operations centers (SOCs) detect and disrupt impersonation and fraud. Moving far beyond traditional, siloed security tools, Doppel natively unifies Digital Risk Protection, Human Risk Management, and Email Security into a single, cohesive ecosystem. The platform empowers organizations to outpace AI-driven threats by identifying malicious activity across domains, social media, paid ads, and the dark web. Under the hood, their sophisticated agentic AI and proprietary Threat Graph automatically correlate disparate threat signals, execute rapid infrastructure takedowns, and continuously train employees using highly realistic deepfake simulations. Trusted by industry leaders like Notion, Coinbase, and Andreessen Horowitz, Doppel remains a definitive cornerstone of the modern cybersecurity landscape, actively bridging the gap between digital and human risk to stop digital threats before they scale.
