After meeting Domini's SRI in 1997, I believed that the time would come when corporate evaluation would change from "economic value" to "social value," and in 2013 I founded and led the Casley Group, which realizes CSV (Creating Shared Value) through IT. In the process, we have built many IT systems and solved many social problems, but we realized that "web 3.0" would bring about tremendous breakthroughs.

Kazumasa Sunagawa

President and CEO Kazumasa Sunagawa

Graduated from Aoyama Gakuin University with a degree and completed an MBA at the same graduate school; currently enrolled in the Master of Technology Management (MOT) program at Tokyo University of Science. During undergraduate studies, focused on the long-term stock price effects of M&A (Statistics), and in graduate school, researched ESG and web3.0. Experienced in large-scale system implementation, proposals, and entrepreneurship at a network infrastructure and IT consulting company, serving public sector, manufacturers, telecommunications, and finance. Through supporting the Great East Japan Earthquake, realized the value of business models that balance economic and social benefits, leading to the establishment of an IT company in 2013 to practice Michael Porter's CSV (Creating Shared Value) strategy. Upon encountering the concept of web3.0, became convinced it was key to realizing CSV. In 2023, ten years later, founded Casley Deep Innovations to achieve CSV through web3.0.
