On March 13, 2025, Satoru Yamamoto, Chief AI Officer (CAIO) and Executive Officer at Dentsu Digital, spoke at the “AWS AI and Data Conference 2025” in Ireland, hosted by Amazon Web Services (AWS). He presented case studies on the utilization of AWS generative AI.

The “AWS AI and Data Conference 2025” brought together developers and leaders gather to create new opportunities through generative AI, machine learning, and data analytics. Through sessions covering technology, business strategy, and hands-on learning experiences, attendees gained practical skills to advance their AI and data initiatives.

At the event, Yamamoto appeared on stage alongside Jeremy Bartosiewicz and Irene Marban Alvarez from AWS UK. Together, they presented a case study demonstrating how Dentsu Digital leveraged AWS generative AI solutions—“Amazon Nova” and “Amazon Bedrock Agents”—to generate advertising banners and analyze distribution data while creating reports through conversational interaction with AI alone. In this case study, Yamamoto highlighted how report workflows within Dentsu Digital were made significantly more efficient, and how the generated ads achieved twice the usual impressions and three times the usual number of clicks.
