Securities DX on the Front Line: renue × Minkab's AI Co-Creation

renue’s Yusuke Yamamoto and Minkab’s Masayuki Ban discuss how they built a call-center training AI and what it actually takes to digitally transform financial infrastructure.

• NISA accounts reached 27 million at end of 2024, growing 3 million per year. The government’s target is 34 million accounts by end of 2027
• Rapid account growth is driving exponential growth in call-center inquiries, while commission revenue stays flat — a structural squeeze
• 23-hour US equities trading is set to launch later this year, further expanding the operational load on brokerages
• The call-center training AI has one AI play the role of an angry customer while a second AI scores the operator’s response — 24-hour role-play practice with no supervisor needed
• Development timeline: two months to a working prototype, three months to full production integration. Minkab deployed it internally first, then rolled it out to brokerages
• Automated generation of fund prospectus market commentary reached the point where AI handles 90% of the work as of February; six months of data now processes in minutes
• Yamamoto frames AI as “a device that makes information flow smoothly” and is exploring expansion into the physical world — next target is blueprint AI for industries like forestry
