Doppel was born to stop deepfakes and online impersonation, but it soon realized that AI doesn't just help defend: it also lets attackers scale their fraud almost without limits. Can a fake website create damage in minutes and disappear in less than an hour? Yes — and that changed the rules of the game.
What Doppel does
The platform uses GPT-5 and models o4-mini together with a technique called RFT or reinforcement fine-tuning. With that, Doppel claims to reduce analyst workload by 80%, triple threat-handling capacity, and move from responses that took hours to actions that happen in minutes.
Why does this matter to you? Today an attacker can generate hundreds of phishing variants, fake domains and spoofed accounts in seconds. If your team waits to manually review each signal, the campaign has likely already done damage. Think of a fake online store popping up during a big sale — it can trick people fast.
