Company Description

Mux provides video infrastructure that enables developers to build video features into their products using APIs for streaming, analytics, encoding, and delivery. The company's platform is used by organizations including Substack, HubSpot, Vimeo, and Paramount for video delivery and performance monitoring. Founded in 2015 by Jon Dahl and Adam Brown, Mux is headquartered in San Francisco and operates an office in London. The company has raised $173.9 million in total funding and reached a market valuation of $1 billion as of April 2021.

The company's recent activities indicate a focus on AI-powered video workflows and open-source development. Mux launched an AI SDK for video analysis, offering features like moderation, summaries, and captions, and has integrated with Vercel's Workflow DevKit. It is also leading the development of Video.js v10, a new version of the video player library. In a recent customer example, the video CRM platform Sendr used Mux to cut its video costs by 90% and scale to 3,500 users in less than three months. Mux's most recent funding round was a $105 million Series D in June 2021, led by Coatue.
