Based in Cologne, DeepL is best known for its AI translation and writing tools and was last valued at around $2 billion. The company says more than 200,000 businesses use its technology worldwide.

"DeepL Voice is already changing how people and businesses work across languages every day, and the Mixhalo team and technology let us bring this to even larger, more complex settings," said Jarek Kutylowski, Founder and CEO, DeepL. "The team has solved one of the hardest problems in live audio, which is delivering high-fidelity sound to thousands of people at once with basically zero latency. Together, we're building the real-time Language AI layer for communication, so people can understand each other naturally wherever they are interacting, whether that's in team meetings, customer calls or even major international events."

“We launched Mixhalo to deliver the best quality audio to live audiences at any size, all within 20 milliseconds. As we expanded into real-time translation, the hardest part was finding technology that could keep up with live speech without compromising quality,” said Vik Singh, Co-Founder, Mixhalo. “After testing technology from nearly all of the leading providers, DeepL was the only one that could deliver accurate translations at the speed we needed to achieve real fluency. We’ve already seen what this combination can do in real-world settings, and by joining DeepL, we can now bring this experience to even more audiences and customers globally.”

“Voice AI is ultimately a fight for latency, quality, and real-world reliability,” said Sebastian Enderlein, CTO, DeepL. “The Mixhalo team has deep experience bringing APIs and audio infrastructure into live environments where there is no room for delay or failure. That expertise is incredibly valuable as we continue to scale DeepL Voice, and their presence in San Francisco brings us even closer to the customers, partners, and developer ecosystem shaping the next generation of AI products.”

Founded in 2016 by Mike Einziger, Ann Marie Simpson-Einziger, and Vik Singh, Mixhalo was created to improve the way people experience live audio at events. Its technology delivers high-quality, perfectly synchronized sound to thousands of people at the same time with very little delay.

The platform has been used at major sports events, entertainment venues, conferences, and brand experiences. Its customers and partners include MLB, NASCAR, Equinox, Verizon, T-Mobile, the Sacramento Kings, and Red Rocks Amphitheatre.

Mixhalo has also supported large global events such as CES, Mobile World Congress, Salesforce conferences, the Databricks AI Summit, and Microsoft AI Tour Paris. In addition, it has been used at concerts and live performances by artists including Metallica, Aerosmith, Sting, and Charlie Puth.
