DeepL, the German machine translation company, has acquired Mixhalo, a startup specializing in live-event audio streaming and translation. The deal includes plans to open a San Francisco office, marking a strategic push into the U.S. market.

The acquisition signals DeepL's ambition to move beyond text translation into real-time audio services for events. Mixhalo's technology delivers low-latency audio directly to attendees' smartphones, which DeepL could pair with its translation models for multilingual experiences.

Financial terms were not disclosed. Mixhalo previously raised funding from investors including True Ventures and Warner Music Group. The three-year-old startup has deployed its platform at concerts, conferences, and sports venues.

By establishing a U.S. foothold, DeepL positions itself closer to large enterprise clients and live-event organizers. The move intensifies competition with incumbents like Google Translate and Microsoft Translator in the audio translation space.
