Cybersecurity startup Doppel has raised $35 million in a Series B round led by Bessemer Venture Partners, pushing its valuation to $205 million. The fresh funding brings its total capital raised to $54.4 million.
The San Francisco-based company helps enterprises fight threats like phishing, impersonation, and social engineering attacks. Its platform uses AI and automation to detect and shut down threats quickly across websites, social media, Telegram, and crypto platforms.
Doppel says its tools help security teams work 10x more efficiently. They offer fast response times, cut through noise, and automate threat takedowns across multiple channels. With cyber risks growing, the company sees AI as the key to staying ahead.
New investors 9Yards Capital and Sozo Ventures joined the round. Existing backers like Andreessen Horowitz (a16z), South Park Commons, Strategic Cyber Ventures, Script Capital, and Sabrina Hahn also returned.
The company raised this round just over a year after its Series A. Since then, it has seen strong growth in both revenue and customers. Doppel is now preparing to scale as demand for AI-based digital risk protection continues to rise.
The startup is also pushing the boundaries of AI-assisted threat detection. It has worked with OpenAI to train smarter detection agents using real-world cybersecurity decisions.
Doppel’s goal is simple: make online threat detection faster, smarter, and easier to act on. As digital attacks become more complex, this kind of proactive defense is becoming essential for modern enterprises
