Mixi reimagines communication with ChatGPT

MIXI, once a pioneer of Japan’s early social networking scene, now primarily operates in the Lifestyle, Digital Entertainment, and Sports industries. The company is known for global successes like the mobile game “MONSTER STRIKE” and the family-focused photo and video-sharing app “FamilyAlbum.”

Staying ahead of many other Japanese companies, MIXI collaborated with OpenAI to roll out ChatGPT Enterprise throughout the organization in just 45 days. The rollout to all employees moved swiftly, sparking numerous internal use cases, with some departmental projects achieving reductions of more than 90% in work hours.

“When operational efficiency rises, we win back time for imagination. And with that time we use AI again, accelerating the next idea.”

Creating a safe environment for AI use

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.
