MIXI needed a secure company-wide AI environment so employees could share GPTs, use internal data safely, and speed up creative, investment, and communication work across a diverse consumer-services portfolio.
Reported impact
MIXI deployed ChatGPT Enterprise in 45 days, exceeded 80% weekly active usage within three months, created more than 1,600 GPTs, reduced some project workloads by over 90%, and sped both marketing and investment-review work substantially.
MIXI replaced ad hoc consumer AI usage with a ChatGPT Enterprise rollout that gave the company a secure, shared environment for internal data, prompt reuse, and custom GPT collaboration. After earlier reliance on individual ChatGPT Plus subscriptions exposed gaps in settings control and data-handling rules, MIXI deployed ChatGPT Enterprise to the whole organization in 45 days with support from OpenAI's customer-success team. The rollout combined general training, new-hire AI onboarding, and an app-building hackathon using the OpenAI Agents SDK so adoption moved from curiosity to reusable tools. Teams then built GPTs for distinct workflows: FamilyAlbum's marketing group uses Copy Checker GPT and Creative Planning GPT to keep ads on-brand and locally nuanced, while the investment division uses VC Fund Initial Review Support to structure incoming proposals. This created a secure platform where expertise is shared as GPTs and employees increasingly build their own operational tools.
Employees work inside ChatGPT Enterprise instead of unmanaged tools, then save successful workflows as GPTs for broader reuse. Brand and campaign inputs flow through marketing GPTs for copy generation, while investment proposals flow through VC Fund Initial Review Support for structured analysis before human decision makers take over.
