Doppel

Market position

Doppel presents itself as the creator and leader of the "social engineering defense" category, positioning against legacy digital risk protection vendors and traditional phishing-simulation and awareness-training tools by unifying external threat detection and disruption with internal human risk management and email security. It reports over 200 customers, dozens of Fortune 500 accounts, and industry recognition including Fortune Cyber60, SINET16, Accel's 100 US AI Startups list, and CyberSecurity Breakthrough's AI-Based Cybersecurity Innovation of the Year.

Doppel argues that it is the only platform combining digital risk protection with human risk management, and the only one where attack simulations are derived from live attacker campaigns mapped in its Threat Graph rather than static templates. Other stated differentiators include multi-channel coverage beyond email (voice, SMS, Teams, Zoom, Telegram, social, ads, telco, dark web, crypto), graph-driven campaign-level intelligence, agentic AI with human-readable detection logic, and disruption of attacker infrastructure rather than detection alone.

Technology

The core technical asset is the Doppel Threat Graph, which links spoofed domains, fake profiles, scam ads and malicious messaging into unified attacker campaigns across web, social, messaging, ads, app stores, email and dark web signals. Doppel scans billions of entities and applies AI/ML models to identify and categorize malicious content, with confirmed threats taken down automatically. Agentic AI is used for autonomous investigation, disruption, phishing triage and generation of multi-step simulation campaigns and training content. Doppel was featured in an OpenAI case study for applying Reinforcement Fine Tuning, fine-tuning OpenAI models on thousands of expert cybersecurity decisions to build an autonomous agent that detects and neutralizes social engineering threats.

History

Founded in 2022 as an AI-driven digital risk protection provider, Doppel published a product overview in December 2024 describing AI/ML scanning of billions of entities across social, domains, paid ads and dark web channels with automated takedowns. It later broadened into a self-described social engineering defense platform: it launched its Human Risk Management product with multi-channel phishing simulation and AI-generated security awareness training in August 2025, raised a $70M Series C in November 2025 led by Bessemer Venture Partners at a valuation above $600M (bringing total raised to $124M) and unveiled a refreshed brand identity, entered Japan in June 2026, made Doppel Email Security generally available in July 2026, and hired a Japan country manager in August 2026.
