Sonix builds software and algorithms that minimise end-to-end audio latency to as little as 30–60 ms, enabling internet conversations that feel as natural as in-person dialogue. Its core technology combines network optimisation with specialised AI models that smooth out jitter and variability, particularly in challenging wireless environments. The company’s capabilities were publicly demonstrated at the 2022 Montreux Jazz Festival, where it delivered industry-leading latency performance. Sonix collaborates closely with academic institutions, including HEIG-VD, to further its research and product development. Recognition in the Swiss startup ecosystem includes placement in the TOP 100 Swiss Startups list in both 2022 and 2023, participation in Venture Leaders Technology and Mobile cohorts in 2022, and winning stage 2 of Venture Kick in 2018. Revenue, user numbers, and other operating metrics were not disclosed in the article, but the firm continues to secure non-dilutive funding to advance its roadmap. The latest financing will support development of new AI algorithms that maintain ultra-low latency even on sub-optimal networks, expanding Sonix’s reach across real-time communication markets.
