Doppel has raised $70 million in a Series C funding round, bringing its total raised to $124 million and valuing the California-based company at more than $600 million, according to SecurityWeek. The round was led by Bessemer Venture Partners, with additional support from multiple previous investors. Founded in 2022, Doppel offers an AI-native social engineering defence platform that protects businesses and individuals from phishing, impersonation and other social engineering attacks.

By using AI and a real-time threat graph, it detects threats across multiple channels, unifies threat intelligence and automates attacker infrastructure takedowns. The company says the funds will accelerate product innovation and expand its simulation and training offerings, as it continues to grow its engineering, product, sales and marketing teams. 20 November 2025.
