LiveKit is a leading provider of open-source infrastructure for real-time audio and video applications, specializing in the foundational technology required to power the next generation of voice AI agents. By offering a high-performance stack that handles the complexities of low-latency communication, the company enables developers to build AI-driven interfaces that can listen, speak, and interact with human-like speed. Its robust platform is designed to scale seamlessly, ensuring that voice-first applications remain reliable and responsive regardless of user volume or geographic distribution.

LiveKit has joined the unicorn club after closing a $100 million Series C funding round, bringing the company's valuation to $1 billion. The round was led by Index Ventures, with participation from Salesforce Ventures, Hanabi Capital, Altimeter, and Redpoint.

LiveKit, headquartered in San Jose, California, United States, was founded in 2021 by Russell D'Sa and David Zhao. "LiveKit is building the development stack and runtime between foundation models and end-user applications. Our goal is simple: make building and scaling voice AI as easy as building and scaling on the web," said LiveKit co-founder and CEO Russell D'Sa. "This round helps us move faster. We're excited to build the voice-driven era of computing with our customers, community, and partners."
