DeepL acquires Mixhalo to bring real-time audio translation to live events

DeepL, the German language translation company known for its text and voice AI tools, has acquired Mixhalo, a startup specializing in real-time audio delivery for live events. The deal is expected to expand DeepL’s capabilities into the live-event translation market, addressing a long-standing pain point for multilingual conference attendees.

From concert audio to conference translation

Mixhalo was founded in 2016 by Incubus guitarist Mike Einziger, violinist Ann Marie Simpson-Einziger, and Vik Singh, who serves as CEO. The company initially focused on improving audio quality at concerts but later pivoted to powering real-time audio for sports stadiums and live events. Over the years, it raised more than $39 million from investors including Fortress Investment, Founders Fund, Defy Partners, and Cowboy Ventures.

Mixhalo’s platform allows event organizers to stream high-quality audio directly to attendees’ smartphones, bypassing the often poor acoustics of large venues. This technology naturally lends itself to language translation: attendees can select their preferred language and hear a translated version of the speaker’s words in near real time.

A natural fit with DeepL

Mixhalo had already been using DeepL as its primary translation provider. The acquisition talks began organically, according to Singh, after he sat next to DeepL’s CTO Sebastian at a customer dinner. “The more we talked, the more obvious the overlap became across the event space, the API, and the application layer,” Singh said in an email.

DeepL has long been a dominant player in text translation but has recently pushed into voice. In 2024, it launched voice-to-text translation in over 33 languages. This April, it introduced a voice-to-voice translation suite designed for multilingual meetings. The Mixhalo acquisition gives DeepL a ready-made distribution channel into live conferences, keynote sessions, and panel discussions.

Why this matters for event organizers and attendees

For anyone who has attended an international conference, the problem is familiar: a speaker delivers a keynote in a language not everyone understands, and attendees scramble to open translation apps on their phones, often with poor results. Mixhalo’s platform solves this by delivering synchronized, high-quality audio directly to each user’s device, with translation embedded in the stream.

DeepL CEO Jarek Kutylowski told Bitcoin World that Mixhalo will serve both as a product and a marketing tool. “The platform will allow us to show how DeepL’s tech works in real-time and in environments like conferences where people are present on the ground,” he said.

The acquisition also marks DeepL’s expansion in the U.S. Mixhalo is based in San Francisco, and DeepL plans to open a Bay Area office to grow its American operations.

Competitive landscape

Mixhalo competes with other real-time translation platforms such as Wordly AI and Palabra, the latter backed by Seven Seven Six. The acquisition gives DeepL a stronger foothold in the live events segment, where demand for multilingual accessibility is growing as global conferences and trade shows rebound post-pandemic.

Singh acknowledged that the rise of voice AI models could have made it harder for Mixhalo to compete on pricing over time, as larger model companies “start encroaching” on its space. Joining DeepL provides the startup with more resources and a broader platform to scale its technology.

Conclusion

The DeepL-Mixhalo acquisition is a strategic move to bring high-quality, real-time translation to live events. For conference attendees, it promises a smoother, more inclusive experience. For DeepL, it represents a step beyond text and meeting translation into the physical event space, backed by a new U.S. office and a proven product.
