KDDI CORPORATION
Tokyo, Japan―December 9, 2025― KDDI today announced its investment in Resemble AI Inc., a leader in responsible generative AI verification technology.
The investment was made through KDDI Open Innovation Fund V (KOIF V), KDDI's corporate venture fund dedicated to co-creating new businesses with promising startups in domains such as AI and Deep Tech, with a focus on both inbound and outbound opportunities for the Japanese market.
Bad actors are using generative AI to create deepfakes that are nearly impossible to detect from authentic content. Subsequently, organizations face mounting pressure to verify digital content authenticity and protect against threats from disinformation to fraud. Deepfake-related fraud caused $1.56B in losses [

Resemble AI's real-time verification technology defends against deepfake threats targeting both humans and AI agents. The company's latest strategic investment round will accelerate global expansion of its AI detection platform, which includes:
- DETECT3B Omni: An industry-leading, enterprise-grade deepfake detection model with 98% detection accuracy.
Resemble Intelligence: A newly launched platform delivering enhanced explainability for multimodal and AI-generated analysis, powered by Google Gemini 3.
Resemble AI's deepfake detection model, DETECT-3B Omni, offers real-time multimodal threat detection for enterprise-grade security. In addition to being trusted by , as well as Fortune 500 telecommunications providers and government agencies, DETECT-3B Omni consistently ranks #1 on 
image and speech Deepfake Detection Leaderboards on HuggingFace, the category's preeminent measurement authority.
KDDI highly values Resemble AI's unique positioning in the deepfake detection market and its potential to lead the industry. Moving forward, KDDI aims to contribute to countermeasures against AI-driven phishing and impersonation fraud in Japan. KDDI is committed to promoting business co-creation through investments in promising startups, aiming to create new business models together with customers and partner companies.
