Sei Sato

Sei Sato – Director & COO Sei Sato joined the Incubation Division in 2008 as an intern, where he launched a new business and gained firsthand experience as a student entrepreneur. In 2009, he officially joined tenso Inc. as a new graduate, and in 2012, he founded “Buyee”, a cross-border e-commerce purchasing support service that has since become the core business of the BEENOS Group. Under his leadership, Buyee has grown to become the No.1 cross-border e-commerce service in Japan. He was appointed Director in 2017. Sato focuses on building sustainable services that continuously deliver value to users, as well as teams where every member’s effort directly contributes to the company’s success. In the field of global e-commerce, he has been involved in various business operations. The service he launched, Buyee, has grown to handle approximately 20 billion JPY in annual transaction volume. Throughout his career, he has engaged in a wide range of areas—business development, customer support, warehouse operations, programming, design, legal affairs, and accounting. (As he humbly notes, the quality may not have been perfect in each area, but this broad exposure has given him a deep understanding of the business as a whole.) He enjoys the process of understanding different team perspectives, aligning diverse interests, and developing cross-functional strategies to solve complex problems and achieve ambitious goals.
