Doppel is an AI-native Social Engineering Defense platform founded in 2022. The company ingests signals from domains, social media, advertisements, messaging apps, and the dark web, using a real-time Threat Graph to detect, correlate, and dismantle attacker infrastructure at machine speed.

Doppel's platform powers four core products: Brand Protection, which detects and removes impersonation, fraud, and counterfeit activity across digital channels with a median takedown time under ten hours; Executive Protection, which safeguards high-profile leaders from impersonation, doxxing, deepfakes, and credential leaks and includes dark-web monitoring and agentic-AI takedowns; Simulation, which runs multi-channel social-engineering attack simulations (email, SMS, voice, Teams, Telegram) using live Threat Graph intelligence and deepfake-enabled vishing; and Security Awareness Training, which delivers threat-informed education with deepfake-driven custom content, AI content generation, micro-coaching, and role-based training flows. The company serves over two hundred customers across financial services, technology, healthcare, retail, media, government, and crypto, including major Fortune 500 brands. Doppel tripled its annual recurring revenue year over year.
