Doppel is a technology company building an AI-native platform called Doppel Vision for social engineering defense (SED), protecting high-profile executives, brands, and organizations from AI-powered threats like phishing, impersonation, deepfakes, disinformation, and fraud.[1][2][3] It serves Fortune 500 companies (dozens protected, with 5x customer growth YoY), notable brands like Coinbase, Ramp, Commerce, and Orrick, and over 200 total customers across financial services, energy, tech, manufacturing, healthcare, and media; the platform solves multi-channel digital risks by detecting threats via a real-time graph, automating takedowns, and delivering simulations/training for employee resilience.[2][3] Doppel has shown explosive growth, hitting 3x ARR YoY, raising a $70M Series C, doubling its team (now 51-200 employees), and expanding features like security awareness training, deepfake content, Helpdesk Mode, and red teaming.[1][2]
Doppel emerged to counter the rapid evolution of AI-driven scams, deepfakes, and impersonations, combining agentic AI with expert cybersecurity insights to create the world's first comprehensive SED platform.[3][4] CEO Kevin Tian has led discussions on modern impersonation threats, including a November podcast on detection methods, while the company fine-tuned OpenAI models with thousands of expert decisions to build autonomous threat neutralization.[1][2] Key milestones include sustaining record growth with 3x ARR, 5x Fortune 500 adoption, international expansion, and a recent $70M Series C led by investors like Bessemer Venture Partners, who praised its speed, ambition, and execution; this funding supports aggressive hiring in engineering, product, sales, and marketing.[2]
Doppel rides the surge in AI-powered deception—deepfakes, generative scams, and social engineering—accelerating due to accessible AI tools, making traditional defenses obsolete.[1][4] Timing is critical amid rising fraud in a post-ChatGPT world, where attackers evolve at machine speed; Doppel counters by disrupting infrastructures proactively, protecting digital trust for enterprises in high-stakes sectors.[2][3] It influences the ecosystem by setting SED standards, partnering with OpenAI, serving ecosystem leaders like Coinbase, and driving measurable outcomes like takedown efficiency, while expanding globally to make businesses "too costly to attack."[2][4]
Doppel is positioned as the unquestioned SED leader, with its $70M Series C fueling product roadmaps like enhanced simulations and international growth amid unrelenting AI threats.[2] Trends like multimodal deepfakes and agentic attacks will amplify demand, potentially pushing ARR past 5x again as Fortune 500 adoption scales; expect deeper OpenAI integrations, more enterprise wins, and ecosystem influence via partnerships.[1][2] As deception proliferates, Doppel's real-time, AI-human hybrid will evolve to safeguard what's real—cementing its disruption of attacker tactics from the high-level overview.[3][4]
Doppel has raised $129.0M across 4 funding rounds. Most recently, it raised $70.0M Series C in November 2025.
