| 2026-03-02 | Exec interviewJapanese-onlydinii founder Mao Yamada steps down as CEO; CTO Kazuki Otomo takes over (effective 1 Feb 2026) 経営体制の変更について dinii announced the founder-CEO change quietly, in a bare notice published a month after it took effect. Yamada stays as founder and chair, and an engineer-led team (CEO Otomo, VP Masuko) now runs the restaurant-POS company. The notice's unusual line about operating 'in compliance with laws' is worth watching for context. Source: dinii (company notice) |
