AI-Native Social Engineering Defense and Digital Risk Protection

Doppel, an IT-Harvest Cyber 150 awardee, provides a security platform focused on neutralizing social engineering threats across corporate digital environments. Its core product, Doppel Vision, ingests and maps online data from domains, social media, email, and enterprise applications to detect impersonation campaigns, phishing infrastructure, and related attacker activity. By consolidating this information into a unified threat intelligence system, the platform enables organizations to identify, disrupt, and remove social engineering threats at scale. Doppel combines large language model processing with analytical workflows informed by cybersecurity practitioners to automate threat detection, triage, and takedown actions.

Their platform combines advanced large language model technology with expert human analysis to eliminate blind spots and remove digital threats. Working alongside OpenAI, Doppel has developed AI models fine-tuned on thousands of decisions made by cybersecurity experts, resulting in the first AI agent capable of autonomously identifying obscure social engineering threats and neutralizing them at scale.

Doppel has raised $124 million to date, including a $70 million Series C in November 2025, a $35 million Series B in May 2025 and a $14 million Series A in early 2024, along with earlier seed financing.
