Mixi reimagines communication with ChatGPT

MIXI，曾是日本早期社交网络领域的先驱，如今主要活跃于生活方式、数字娱乐和体育产业。公司以全球成功的产品闻名，如手机游戏《怪物弹珠》（MONSTER STRIKE）和面向家庭的照片及视频分享应用“FamilyAlbum”。

领先于许多日本企业，MIXI与OpenAI合作，仅用45天便在全公司范围内部署了ChatGPT Enterprise。全员快速上线，激发了大量内部使用场景，部分部门项目的工时减少超过90%。

“当运营效率提升时，我们便能赢回想象的时间。利用这段时间，我们再次使用AI，加速下一个创意的诞生。”

—— MIXI首席技术官 吉野淳平

创建安全的AI使用环境

MIXI的企业宗旨是“丰富沟通，激发快乐时刻”，公司始终提供与此使命相符的服务。创造难忘体验和促进有意义的连接需要持续创新和新思路。

意识到AI的潜力，MIXI迅速采用AI，为1000多名员工补贴ChatGPT Plus订阅。但在数据训练设置和内部数据处理规范方面遇到挑战。董事兼高级企业官员村瀬辰真回忆道：“我们需要逐个检查员工的AI设置，公司数据使用规则不明确。显然必须建立一个安全统一的环境，让所有人都能安全使用AI。”

随着ChatGPT Enterprise的全公司部署，员工现在可以轻松且安全地共享专业知识和GPT工具。能够安全访问内部数据，使团队工作更快、更高效。

45天快速部署，得益于贴心支持

通常向数千人推广新平台需要数月时间，MIXI却在45天内完成，这得益于与OpenAI客户成功团队的紧密合作。面对各部门关于个人数据处理和运营顺畅的疑虑，OpenAI提供了其他企业上线经验的应对方案。

上线后，MIXI与OpenAI开展了三大重点培训项目：

• ChatGPT 101培训：面向全员的直播课程，聚焦日常工作中缩短工时的提示技巧。
• 新员工研讨会：为2025年4月入职毕业生举办的生成式AI入职培训，从第一天起培养AI素养。
• 黑客松：工程师们利用OpenAI Agents SDK进行实战冲刺，将理论兴趣转化为可交付的原型应用。

这些全面举措使众多MIXI员工迅速掌握ChatGPT和OpenAI产品，激发了各部门的关键应用场景。

用GPT强化FamilyAlbum的品牌诉求

FamilyAlbum是一款帮助父母与亲友分享孩子照片和视频的应用，是MIXI最受欢迎的产品之一，拥有超过2500万用户，覆盖175个国家和地区，支持七种语言。该应用助力全球家庭建立新的沟通和连接方式。

FamilyAlbum业务部助理总经理平田信久表示：“在广告创意策划中，我们利用GPT提升品牌理解并设计AB测试，每月节省约28小时工作时间。团队开发了促进协作文化的GPT，成员们积极共同测试和优化提示词。”

具体应用包括：

• 文案检查GPT：审查标语，确保符合“FamilyAlbum风格”。若用词过于强烈或激进，GPT会建议更柔和、符合品牌语调的表达。
• 创意策划GPT：帮助非母语者生成符合品牌价值和本地文化的全球广告文案。用户指定语言和目标受众，GPT返回从标题到行动号召的完整文案套装。

平田表示：“AI已助力提升运营效率，我们正着眼于更深层次的应用。目标是让AI不仅成为团队伙伴，更成为产品核心。结合AI技术与FamilyAlbum愿景，我们相信能进一步深化和丰富家庭间的连接。”

将分析师时间转向人际交流

MIXI投资部门管理着70多个基金，投资组合涵盖3000多家公司（含间接投资）。

企业发展负责人荒木豪志表示：“手动监控众多投资标的已不现实，AI能力不可或缺。现在，我们用ChatGPT进行投资评估和监控，大幅提升风险评估效率并创造新价值。”

投资部门开发了专用GPT“VC基金初审支持”，结构化整理VC基金提交的提案，显著缩短初审时间并提升评估质量。过去单笔投资评估需1至2小时，该GPT将时间缩短至5至10分钟，确保团队成员均能产出高质量结果。利用ChatGPT Enterprise，部门多次实现超过70%的工作量减少。

荒木强调，节省的时间现被有效用于人际沟通和关系建设，这些是AI无法替代的人类专长。

人人都是开发者：1600多个GPT持续增长

自MIXI全面推行ChatGPT Enterprise后，三个月内超过80%的员工成为每周活跃用户，创建了1600多个GPT。村瀬指出：“部分项目工时减少超过90%。员工现在能自行构建工具，不再依赖开发者，仿佛人人都成了开发者。”

吉野也表示，自部署以来组织能力大幅提升，MIXI将继续利用OpenAI产品打造以沟通为核心的新体验。“我们计划持续充分利用ChatGPT和OpenAI API，创造MIXI所倡导的真正有意义的连接空间和机会。”

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.

A 45-day deployment, powered by hands‑on support

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. 

Strengthening FamilyAlbum’s Message with GPTs

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.”

• Copy Checker GPT: Reviews taglines to ensure they feel “FamilyAlbum‑like.” If a proposal includes strong or aggressive wording, the GPT suggests softer phrases aligned with the brand voice.
• Creative Planning GPT: Enables non‑native speakers to generate global ad copy that respects both brand values and local nuance. Users specify language and target persona; the GPT returns full headline‑to‑call‑to‑action sets.

“While AI has already contributed to improving our operational efficiency, we’re now looking beyond that. We aim to evolve AI from being merely a partner within our teams to becoming an integral part of our products. Our goal is to deliver more personalized, warm, and intuitive experiences to families around the world. By combining AI technology with FamilyAlbum’s vision, we believe we can deepen and enrich family connections even further,” says Hirata.

Redirecting analyst hours toward human connection

MIXI’s investment division invests in startups and funds, having invested in over 70 funds and holding a portfolio of over 3,000 companies, including indirect investments.

“It has become impossible to manually monitor all of our numerous investment targets,” explains Gohshi Araki, Head of Corporate Development. “The capabilities provided by AI were indispensable. Now, we use ChatGPT for investment evaluations and monitoring, significantly aiding risk assessment and creating new value.”

The investment division has developed a specialized GPT called “VC Fund Initial Review Support,” designed to structurally organize proposals submitted by VC funds. This tool substantially reduces the time spent on initial investment reviews and improves overall evaluation quality. Previously, evaluating a single investment took between 1 to 2 hours, but this GPT has shortened that time to just 5 to 10 minutes, ensuring consistent high-quality results across all team members. Moreover, the division has seen several instances where leveraging ChatGPT Enterprise has reduced workloads by over 70%.

Mr. Araki highlights that the saved time is now effectively redirected toward interpersonal communications and relationship-building tasks—activities uniquely suited to human engagement.

Everyone’s a developer: 1,600 GPTs and counting

Since MIXI implemented ChatGPT Enterprise company-wide, over 80% of employees became active weekly users within three months, creating more than 1,600 GPTs. Mr. Murase noted significant improvements: “Some projects have cut work hours by over 90%.” He added, “Employees can now build tools themselves instead of relying on developers. It’s like everyone has become a developer.”

Yoshino echoes this sentiment, saying the organization’s capabilities have broadened since the rollout and that MIXI intends to keep using OpenAI products to craft new communication-focused experiences. “We plan to continue making full use of ChatGPT and the OpenAI API to create the space and opportunity for truly meaningful connections that MIXI champions.”
