LiveKit builds and operates a real-time voice and video infrastructure platform that lets developers embed low-latency audio and video streaming into AI products. Originally launched in 2021 by Russ d’Sa and David Zhao as an open-source toolkit, the company evolved into a managed cloud service after large enterprises sought turnkey, scalable deployments. Its technology underpins OpenAI’s ChatGPT voice mode and is also used by xAI, Salesforce, Tesla, 911 emergency service operators, and mental-health providers. LiveKit’s business rides the surge in demand for voice-enabled AI experiences, positioning it as a backbone provider for conversational agents and other latency-sensitive services. Although specific revenue figures are not disclosed, the company’s latest financing values it at $1 billion, indicating strong investor confidence. Future plans were not explicitly detailed in the article, but the fresh capital is expected to fuel further product expansion and enterprise adoption.
