Doppel is an AI-native platform built to detect and dismantle social-engineering attacks: phishing domains, fake executive accounts on social media, fraudulent marketplace listings, and lookalike apps impersonating a brand. Former Uber engineers Kevin Tian and Rahul Madduluri founded the company in 2022.
Rather than only alerting security teams to a threat, Doppel's agents take autonomous action to disrupt and remove malicious infrastructure once detected, scanning domains, social platforms, app stores, and marketplaces continuously instead of on a scheduled crawl. The company also runs training and simulation modules so security teams can rehearse responses to the same attack patterns Doppel detects in the wild.
Doppel is built for enterprise security and brand-protection teams at companies large enough to be a repeated impersonation target, not individual consumers. Pricing is custom and quoted directly by sales; the company has raised $124 million across four rounds, including a $70 million Series C in November 2025 that valued it above $600 million.
