Mixer Gaming & Tech

History and Founding

Mixer began as Beam Interactive, a startup founded by Matthew Salsamendi and James Boehm in early 2016. The company was based in Seattle and quickly gained attention for its proprietary FTL (Faster Than Light) streaming protocol, which cut the typical broadcast delay from several seconds to under a second, enabling near-real-time interaction between streamers and viewers. Microsoft acquired Beam in August 2016, seeing it as a strategic asset to bolster its gaming ecosystem against Amazon’s Twitch and Google’s YouTube Gaming. The service was rebranded as Mixer in May 2017, and Microsoft deepened its integration with Xbox One, Windows 10, and later Project xCloud.

Business Model and Revenue

Mixer monetized through several channels. Viewers could purchase a virtual currency called Embers with real money and use them to trigger on-screen “Skills” that rewarded streamers financially. A free currency, Sparks, was earned through watch time and used for similar interactions but did not directly generate revenue. Mixer Pro, a monthly subscription offering ad-free viewing, custom emotes, and chat perks, provided recurring subscription income. The platform also took a cut of tips and subscriptions from streamers, though exact percentages were not publicly disclosed. Microsoft also used Mixer to promote its own games and services, such as Xbox Game Pass and Halo, indirectly supporting the broader business.

Key Products and Features

Mixer’s core technical differentiator was the FTL protocol, which delivered sub-second latency. The MixPlay SDK allowed game developers to create interactive overlays, enabling viewer votes, item drops, and other real-time game modifications. The platform’s virtual economy comprised Sparks (free, earned by watching) and Embers (purchased with real money), which viewers could spend on Skills that appeared on stream. Channel Progression gamified the viewing experience, letting users level up through engagement to unlock emotes, chat badges, and priority support. CATbot provided automated chat moderation, and Mixer Pro offered an ad-free subscription tier. These features collectively aimed to differentiate Mixer from Twitch by making the audience an active part of the broadcast.

Market Position and Competition

Mixer never captured more than a single-digit share of the game-streaming market. According to industry data, Twitch held roughly 70–80% of viewership hours, while YouTube Gaming occupied most of the remainder. Despite securing exclusive contracts with Ninja and Shroud—two of the most popular streamers globally—Mixer could not retain their audiences long term; many viewers continued to watch their content via other platforms or simply did not migrate. The high cost of these exclusives (estimated at tens of millions of dollars) and the failure to achieve critical mass led Microsoft to conclude that competing with Twitch was unsustainable.

Shutdown and Legacy

On June 22, 2020, Microsoft announced it would shutter Mixer on July 22, 2020. As part of the closure, the company partnered with Facebook Gaming to offer a transition path for streamers and viewers, and Microsoft refunded all outstanding Ember balances and Mixer Pro subscriptions. The decision reflected a strategic pivot toward its own subscription ecosystem (Xbox Game Pass, Game Pass Ultimate, and cloud gaming via xCloud) rather than continuing to invest in a standalone streaming platform. Mixer’s technology, particularly the FTL protocol and MixPlay, was cited by some developers as ahead of its time, but the platform ultimately could not overcome the network effects and entrenched community of Twitch. The service is now defunct, and mixer.com redirects to Facebook Gaming.

Leadership During Active Period

Matthew Salsamendi and James Boehm served as co-founders and led the startup through its Microsoft acquisition; both departed the company in 2019. Within Microsoft, Mixer was managed under the Xbox division led by Phil Spencer (Executive Vice President of Gaming) and Sarah Bond (Corporate Vice President of Gaming Ecosystem). Ben Favreau held the role of Product Marketing Manager during the platform’s peak years, as noted in GeekWire interviews.
