San Francisco-based Doppel has secured $35 million in a Series B funding round led by Bessemer Venture Partners, bringing the company’s total funding to $54.4 million.
Doppel said the new investment values the company at $205 million and provides runway to meet enterprise demand for AI-assisted tools to detect and mitigate digital impersonation, phishing, and other social engineering threats.
Doppel’s ambition is to build AI-powered technology for continuous monitoring, rapid detection, and seamless takedowns across traditional channels like web domains, social media platforms, and the dark web as well as emerging channels such as Telegram and crypto.
The company is arguing that AI and automation will enable analysts to operate at 10x greater efficiency with high signal-noise detection, faster takedowns, and average support response times in minutes.
Doppel said new investors 9Yards Capital and Sozo Ventures joined the Series B alongside existing backers Andreessen Horowitz (a16z), South Park Commons, Strategic Cyber Ventures, Script Capital, and Sabrina Hahn.
The fresh capital comes just over a year after Doppel’s Series A and follows a period of reported customer and revenue growth.
Doppel is one of several companies experimenting with AI-assisted workflows for early-stage threat detection, and has also worked with OpenAI to refine detection agents trained on cybersecurity decision data.
