NTT DOCOMO Ventures Invests in Doppel, Inc., Provider of an AI Defense Platform Against Brand Impersonation and Phishing

NTT DOCOMO Ventures, Inc. (Headquarters: Minato-ku, Tokyo; CEO & CCO: Yuko Sasahara; hereinafter “NDV”) is pleased to announce that, through a fund that it manages, it has invested in Doppel, Inc. (Headquarters: Covina, California, USA; CEO: Kevin Tian; hereinafter “Doppel”), a company providing an AI-powered defense platform that protects against brand impersonation and phishing attacks.

Doppel’s AI-powered defense platform protects enterprises and individuals from social engineering attempts to exploit psychological vulnerabilities or human error to steal information. The platform continuously monitors a wide range of channels, including social media, websites, mobile apps, and digital advertisements, enabling early detection and blocking of risks such as phishing, impersonation, fraudulent brand sites, and cyberattacks targeting digital infrastructure.　Furthermore, instead of relying on human analysts, the platform uses AI to proactively identify and track attacker techniques, visualize the structure of attacks in real time, and integrate with internal systems and Security Operation Centers (SOCs) to perform end-to-end threat containment.

As a result, organizations can prevent brand damage and customer harm before they occur, maintaining a highly trustworthy digital environment. Today, more than 5% of Fortune 500 companies have already adopted Doppel’s AI defense platform.

Amid a fundamental shift in cybersecurity, where attackers increasingly target “people” instead of “systems,” Doppel is rapidly emerging as a leading platform that enables automated, AI-powered defense in the new domain of social engineering protection. The company is expected to continue scaling as this market expands.

The NTT DOCOMO Group aims to build secure and reliable digital infrastructure through its telecommunications and digital services. Through this investment, NTT DOCOMO Ventures will deepen collaboration with Doppel and work to enhance digital trust across enterprises and society, while driving the creation of new value.
