Synthesia Teams Up with Mux to Power Scalable, AI-Driven Video Generation for Global Enterprises

Synthesia, the leading AI video generation platform, has announced a strategic partnership with Mux, a pioneer in video infrastructure, to support its rapid global expansion. The collaboration empowers Synthesia to scale its AI-powered video capabilities while optimizing performance and cost-efficiency for its growing enterprise customer base.

Synthesia is transforming how businesses create video content by enabling automated video production through AI avatars—revolutionizing use cases like corporate training, internal communications, and personalized customer engagement. As demand surged, the company needed an infrastructure partner capable of supporting high-volume, global video delivery without burdening its internal teams with complex backend management.

“AI enables quality video creation at a speed and scale that wasn’t possible before. This has implications on our storage and delivery costs,” said Jake Gillespie, Engineering Manager at Synthesia. “Mux was very proactive in making sure our costs were managed through features like cold storage and quality levels that allow us to optimize spend while delivering the right experience our users need.”

Initially, Synthesia relied on a custom-built video backend that couldn’t keep pace with the exponential growth of AI-generated content. Unlike traditional video production, the AI-based process generates significantly more output, requiring a platform that can ensure high-quality global delivery while also keeping storage and streaming costs in check.

“The developer experience with any tool is critical – the time that engineers spend on learning and implementing technology is paramount for moving quickly,” added Gillespie. “With Mux, the simplicity and accessibility of the docs, and the way Mux makes the product available with very minimal barriers to entry, were really important for us getting up and running quickly. Mux fully takes care of the video workflow, allowing us to focus on everything that’s uniquely valuable to Synthesia.”

Through this partnership, Synthesia is able to offload the heavy lifting of video infrastructure to Mux, allowing its teams to focus on core AI innovation. By leveraging Mux’s powerful capabilities—including automated cold storage and adaptive quality levels—Synthesia can support customers who generate high volumes of training content that’s consumed periodically, such as annual compliance courses. These intelligent cost controls result in significant long-term savings while maintaining a premium user experience.

The collaboration also improves engineering efficiency. Mux’s intuitive APIs and well-documented developer tools accelerate Synthesia’s product development cycles, reducing time-to-market for new features and services.

“AI video platforms like Synthesia need the best video infrastructure — high scale, global quality delivery, and intelligent cost optimization,” said Jon Dahl, CEO at Mux. “Our developer-first platform is purpose-built for the dynamic, high-scale demands of AI-generated video, letting companies focus on innovation instead of managing complex workflows.”

As AI continues to reshape how organizations engage their audiences, the demand for scalable, intelligent video infrastructure has never been higher. This partnership positions both Synthesia and Mux at the forefront of enabling the next generation of enterprise video experiences.
