Doppel Enters Japan, Marking Next Phase of Global Expansion

Social engineering defense leader surpasses 250 customers, launches new email security offerings, and adds industry veterans to executive team

SAN FRANCISCO, June 16, 2026 /PRNewswire/ -- Doppel, the AI-native Social Engineering Defense (SED) platform, today announced a series of milestones, including its formal expansion into Japan. The expansion is anchored by a strategic alliance with the CTCSP Corporation, reinforcing Doppel's growing international footprint as enterprises confront a new wave of AI-driven social engineering threats.

The announcement follows a period of rapid growth, including 3x ARR growth year-over-year, and a more than 5x increase in Fortune 500 customers. Doppel's total customer base has surpassed 250 organizations, including Poshmark, Ameren, BitGo, and the San Francisco 49ers. Additionally, Doppel has expanded its platform with new capabilities across email security, phishing investigation, and AI-driven threat detection. These milestones have been accelerated by international hiring efforts across Canada and the Netherlands, as well as Doppel's expansion into EMEA last October.

As part of its expansion into the Japanese market, Doppel has partnered with CTCSP Corporation, a member of the ITOCHU Techno-Solutions (CTC) Group, to deliver the Doppel platform across Japan. Leveraging CTC Group's extensive enterprise customer base and strong capabilities in system integration, security operations, and managed services, CTCSP will provide end-to-end support from go-to-market activities and implementation through to customer enablement. This will enable Japanese enterprises to effectively adopt and operate the Doppel platform.

"The rise of AI-driven deception means that traditional, siloed security measures are no longer sufficient for the Japanese enterprise," said Katsuya Kami, President and CEO at CTCSP. "Social engineering represents a critical risk that threatens business continuity and brand reputation. Our mission at CTCSP is to enhance the digital reliability of Japanese companies by curating the world's most advanced technologies. By partnering with Doppel, we are delivering AI-native social engineering defense to ensure companies across Japan are resilient against the next generation of AI-driven threats."

"Japan represents a critical frontier in the fight against global social engineering," said Kevin Tian, CEO and Co-founder of Doppel. "Our partnership with CTCSP and the trust of customers in the region validate our mission to protect the world's most innovative companies from AI-driven attacks. We are fully committed to investing in Japan, building a world-class local team, and ensuring our partners have the most advanced SED tools at their disposal."

Product Innovation
Doppel continues to redefine the SED category with a series of major product milestones. On May 27, the company announced Doppel Email Security, the newest layer of its unified, AI-native platform purpose-built to protect against the entire social engineering attack chain.

These advancements are anchored by the new AI Content Builder, which allows customers to automatically generate engaging, localized training content based on their specific company policies, protocols, and branding, all grounded in intelligence from the Doppel Threat Graph and real-world attack patterns.

Solidifying its position as a trusted leader in the AI space, Doppel recently announced it has earned three International Organization for Standardization (ISO) certifications, including being among the first 350 organizations worldwide to achieve the ISO 42001 certification for AI governance standards.
