Doppel offers a social engineering defense (SED) platform that leverages agentic AI and a real-time threat graph to spot impersonation, phishing, fraud, and other attacks across social media, messaging apps, paid ads, and the dark web. Its Digital Risk Protection suite unifies threat alerts and automates attacker-infrastructure takedowns, while its Human Risk Management products provide deepfake-driven simulations and security-awareness training. Since launching its Simulation product in August, that module already represents a material share of Q3 bookings, signaling strong early demand. The company reports 3× year-over-year ARR growth and a more than 5× increase in Fortune 500 customers, now serving over 200 organizations including Coinbase, Ramp, Commerce, and Orrick. Doppel has doubled its headcount over the past year and continues to hire aggressively as it expands internationally. A collaboration with OpenAI has enabled the firm to fine-tune models that autonomously detect and neutralize complex social-engineering threats in real time. Following its latest $70 million Series C round, Doppel has raised $124 million to date at a valuation exceeding $600 million.
