Doppel Raises $35 Million to Combat Deepfakes and Phishing with AI

Defend what’s real, disrupt what’s not, says the team of Doppel, the AI-powered social engineering defense platform that has recently announced a $35 million Series B funding round, bringing its total funding to $54.4 million. The round, which values the company at $205 million, is led by Bessemer Venture Partners, with participation from new investors 9Yards Capital and Sozo Ventures. Existing backers including Andreessen Horowitz (a16z), South Park Commons, Strategic Cyber Ventures, Script Capital, and Sabrina Hahn have also doubled down on their support, reflecting growing confidence in Doppel’s mission and traction.

Founded to tackle one of the most insidious and fast-evolving categories of cyber threats social engineering Doppel has grown rapidly since its Series A just over a year ago. In that time, the company has quadrupled its enterprise customer base, tripled its annual recurring revenue, and achieved an eightfold increase in expansion revenue from existing clients.

Since 2022, the company has maintained a staggering 230% compound annual growth rate, a signal not just of momentum, but of product-market fit in an industry scrambling to adapt to AI-powered threats.

Elliott Robinson, partner at Bessemer Venture Partners, calls Doppel “the market leader in social engineering defense,” citing its proprietary AI models as critical infrastructure in an era where phishing, deepfakes, and impersonation attacks are becoming hyper-personalized and increasingly difficult to detect. “We’ve been blown away by the company’s growth and the real-world efficacy of its platform,” Robinson said. “Doppel is tackling a problem that’s only growing more sophisticated by the day, and doing so with remarkable precision and speed.”
