NOMINATION HIGHLIGHTS

Doppel is not simply improving digital risk protection and human risk management. It is defining a new category: AI-native Social Engineering Defense.

As generative AI enables attackers to produce convincing deepfakes, impersonations, phishing campaigns, and coordinated fraud at unprecedented scale, trust in digital identity has eroded. Modern attacks no longer bypass systems; they exploit people. The internet was not designed to verify identity or protect likeness in a world of AI-generated deception, and enterprises are struggling to detect and disrupt campaigns that span domains, social media, messaging platforms, paid advertising, voice, and the dark web.

Doppel was founded in 2022 after recognizing how easily AI could be weaponized for impersonation. From the beginning, the company built solutions for the reality that social engineering has become infrastructure-based, multi-channel, and machine-scaled.
The AI-native Doppel platform uses agentic AI to proactively detect, dismantle, and build resilience against impersonation and fraud infrastructure. Rather than generating fragmented alerts, the platform correlates attacker assets into unified campaigns, revealing how deception operates across people, platforms, and time, and informing airtight training programs based on reality.

At the center of this innovation is the Doppel Threat Graph, which connects spoofed domains, fake accounts, messaging activity, ad networks, and supporting infrastructure into a living intelligence system. Built on OpenAI GPT-5 and o4-mini models and refined through reinforcement fine-tuning using thousands of analyst decisions, Doppel autonomously classifies and removes impersonation, phishing, and deepfake threats in minutes while maintaining explainability and confidence in automated outcomes.

Doppel extends beyond detection into preparedness. Its multi-channel Simulation engine recreates real-world attacks across voice, email, and messaging platforms. In Fortune 500 trials, employees treated 100 percent of AI voice clones as legitimate callers engaged in 6-minute-long conversations with helpdesk employees, exposing critical gaps before real attackers could exploit them.

This combination of category innovation and measurable impact has driven 3x year-over-year ARR growth and a 5x expansion in Fortune 500 customers. In November 2025, Doppel raised a $70 million Series C led by Bessemer Venture Partners, with participation from George Kurtz, co-founder and CEO of CrowdStrike.

By unifying detection, disruption, and human readiness, Doppel is building the security infrastructure required to defend trust itself in an era where AI-powered deception is scalable, believable, and relentless.
