Doppel, a startup cofounded by CEO Kevin Tian and CTO Rahul Madduluri, is leveraging AI to combat social engineering attacks. The company has developed AI agents that scour the internet, dark web, and social media for fraudulent activity, flagging copycat websites, fake user accounts, and malicious advertisements. These agents process 100 million alerts daily with about 90% accuracy, significantly improving threat detection.
Background
In 2022, Tian founded Doppel to counter AI-powered fraud by using AI against AI. Initially focused on NFT-related fraud, the company broadened its scope in 2023 to serve various industries. Doppel replaced human contractors with AI agents in September 2024, automating 30% of its security operations.
Success Stories
Notion, a productivity software company, saw a significant reduction in attacks after partnering with Doppel. The startup’s AI agents quickly took down thousands of malicious campaigns, making Notion “a very expensive target” for fraudsters.
Technology
Doppel’s “threat graph” maps relationships between social engineering campaigns, enabling better tracking of malicious hackers. This technology helps safeguard businesses against future attacks by providing a comprehensive view of threat actor infrastructure.
Growth
Doppel has attracted 180 enterprise customers, including United Airlines, OpenAI, and Coinbase, and tripled its revenue year-over-year. The company recently secured $35 million in new funding, bringing its total venture backing to $55.5 million and valuation to $205 million.
Industry Impact
As AI enables new types of social engineering attacks, Doppel is at the forefront of combating these threats. The company’s AI-powered solution is crucial in protecting businesses from sophisticated attacks that include AI-generated images, audio, and fake profiles.
