MIXI’s corporate purpose is “to enrich communication and inspire moments of joy,” and the company consistently delivers services aligned with this mission. Creating memorable experiences and fostering meaningful connections requires continuous innovation and fresh ideas.

Recognizing this potential, MIXI swiftly embraced AI, subsidizing ChatGPT Plus subscriptions for over 1000 employees. However, challenges arose regarding consistent data-training settings and internal data handling guidelines. Tatsuma Murase, Director and Senior Corporate Officer, recalls: “We needed to check each employee’s AI settings individually, and our rules for using company data were unclear. It was obvious we had to create a secure, unified environment for everyone to safely use AI.”

With the company-wide adoption of ChatGPT Enterprise, employees now easily and securely share their expertise and GPTs. Having confidence to safely access internal data has enabled teams to work faster and more efficiently than ever before.

Rolling out any new platform to thousands of people usually takes quarters. MIXI finished in 45 days thanks to a tight partnership with OpenAI’s Customer Success team. When different departments raised concerns—from personal data handling to ensuring smooth operations—OpenAI provided mitigation playbooks drawn from other enterprise launches.

After going live, MIXI and OpenAI ran three flagship enablement programs:

• ChatGPT 101 training: A live session for every employee, focused on day‑to‑day prompts that shorten real work.
• New‑hire workshop: A generative AI onboarding session for April 2025 graduates, building AI fluency from day one.
• Hackathon: A hands‑on sprint where engineers built apps with the OpenAI Agents SDK, turning theoretical interest into shipped prototypes.

These comprehensive efforts allowed many MIXI employees to quickly adopt ChatGPT and OpenAI products, sparking essential use cases across diverse departments.

FamilyAlbum is an app designed to help parents share photos and videos of their children with loved ones, and is one of MIXI’s most popular apps, with over 25 million users across 175 countries and regions, available in seven languages. The app helps families worldwide foster new ways of communication and connection.

“In our advertising creative planning, we’re using GPTs to enhance brand understanding and design AB tests, resulting in a reduction of approximately 28 hours of work per month,” says Nobuhisa Hirata, Assistant Chief General Manager of the FamilyAlbum Business Department. “Our teams have developed GPTs that encourage a collaborative culture, where members actively test and refine prompts together.”
