What is Doppel?
Doppel is a ai-native social engineering defense company. Doppel provides an AI-native social engineering defense platform that unifies digital risk protection, human risk management, executive protection, brand protection, and email security.
Doppel provides an AI-native social engineering defense platform that unifies digital risk protection, human risk management, executive protection, brand protection, and email security. The platform protects brands, executives, and employees from impersonation, doxxing, deepfakes, phishing, and fraudulent campaigns across open, social, email, and dark-web channels. The durable market signal is that Doppel sits close to a budget owner: security, AI platform, healthcare operations, engineering, developer productivity, or defense procurement depending on the account.
As of June 2026, the company profile is best read through product adoption, funding stage, leadership, and ecosystem partnerships rather than through public revenue, because most companies in this batch do not disclose ARR. Buyers generally evaluate Doppel on deployment risk, integration depth, compliance posture, and measurable operational impact.
