Original title: Credit Saison achieves 954% ROI in a ChatGPT Enterprise pilot
A 315-person pilot saved 14 hours a month per person, and Credit Saison rolled ChatGPT Enterprise out companywide in September 2025.
Credit Saison, a Japanese credit-card company with about 31.16 million cardholders, ran a ChatGPT Enterprise pilot with OpenAI from late June to early August 2025. The company says the pilot beat targets of 500% ROI and 7.5 hours saved per person, and it approved a companywide rollout one month after the pilot ended. Employees used custom GPTs for shareholder-meeting rehearsal, store debriefs, and customer research; the engineering team’s Codex use is credited with about 850 hours saved per month.
