Marubeni Opens Its 10,000-User Generative AI Platform 'Marucha' to Outside CompaniesA · FULL TRANSLATION
- Marubeni Information Systems begins external sales of the group-proven AI platform
- Marucha reached roughly 10,000 monthly active users inside Marubeni Group
- Prove-internally-then-sell is becoming Japan Inc.'s standard AI playbook
Japan Inc.'s AI commercialization has found its formula: get ten thousand of your own people using it daily, then sell the platform. Marubeni Information Systems announced external availability of 'Marucha,' the generative AI platform honed across Marubeni Group with around 10,000 monthly active users — effectively knocking on clients' doors with a year of trading-house combat records. The product isn't the model but everything wrapped around it: access control and security, Japanese business templates, department-level use-case libraries, rollout and training know-how. Buyers skip the potholes of building solo; Marubeni's IT arm turns from cost center to revenue engine. NTT Data, Hitachi and Mitsubishi-affiliated firms run the same play — Japan's B2B AI market is shifting from selling models to selling usage. The internal proving ground, it turns out, is the most persuasive product catalog.
[Summary translation of PR TIMES release] Marubeni Information Systems (President Yoshihiro Sato), part of the Marubeni I-DIGIO Group's Advanced Integration segment (Segment CEO Shigeo Yamanaka), announced it will begin offering 'Marucha,' the generative AI platform proven across the Marubeni Group with roughly 10,000 monthly active users, to external companies. The platform's effectiveness has been validated in real business settings group-wide, and the operational know-how accumulated through internal rollout will now support external clients' AI adoption.
