Strengthening creative production workflows and advancing new forms of expression and experiences powered by generative AI.

Tokyo, Japan, June xx, 2026 — MIXI, Inc., announces that it has entered into an enterprise partnership with Runway AI, Inc. (“Runway”), a global leader in the fields of video production, editing, animation, and visual expression using generative AI.

Runway is advancing research and development of generative video and multimodal AI models, as well as providing a creative AI platform that supports the production workflow of creators and companies. Across film and television, advertising, VFX, gaming, and other mediums where advanced visual expression is required, Runway has helped millions of customers open up new possibilities with creative production using generative AI.

MIXI provides a variety of communication services in order to provide space and opportunity for truly meaningful connections. In recent years, we have positioned generative AI as an important technology to support creators’ expression and production processes, and are promoting its use in creative production work. As part of this process, we have been using Runway in our production workflow for video, animation, effects, and visual proposals.

Through this partnership, we will further expand our use of Runway and strengthen our creative production framework. The two companies also plan to collaborate to create new creative use cases utilizing generative AI in games, animation, and interactive experiences.

Examples of How We’ve Used Runway

● A video production for MONSTER STRIKE that would previously have required 21 days was completed in just three days, entirely in-house.
● A brand film that would have taken 20 days with traditional tools was produced in seven, with a hybrid creative pipeline combining live action and generative video.
● Visual proposals for character animations, in-app effects, and screen transitions can now be created in as little as five minutes, compared with a process that previously took several days.

Comments From Both Companies

Tatsuma Murase, Director and Senior Corporate Officer of MIXI:

“MIXI’s tagline, ‘Connection with meaning’, illustrates our commitment to creating products that venerate the experiences and emotions created when users interact with one another. Runway is a key partner in our creative production workflow, expanding the possibilities for expression in the areas of sports, lifestyle, and digital entertainment. As AI expands the possibilities of production, what will become more important is what we create, the perspectives we have, and what kind of stories and experiences we provide to our users. We are very much looking forward to working with Runway to create new value by pursuing ideas and expressions that have been difficult to realize in the past.”

Cristóbal Valenzuela, Co-Founder and Co-CEO of Runway:

“MIXI is a perfect example of what we see in just about every successful enterprise deployment: find an initial, specific use case, prove success and expand rapidly. The speed at which MIXI has adopted Runway across its businesses is incredible. As one of our earliest partners in Japan, it’s exciting to see Runway used at scale in such a wide variety of ways.”

MIXI and Runway will continue to explore the possibilities of creative production using generative AI, aiming to deliver richer communication-based experiences to users.
