LiveKit raised $100 million at a $1 billion valuation in a round led by Index Ventures with participation from Altimeter Capital, Hanabi Capital, and Redpoint Ventures. The company, founded in 2021 and originating as an open-source low-latency audio/video project, now operates a managed cloud platform used by OpenAI (for ChatGPT's voice mode), xAI, Salesforce, Tesla, and various emergency and healthcare providers.
This raise frames voice as a distinct infrastructure layer — think real‑time CDN for conversational AI — where latency, reliability and compliance matter more than ever. For streaming executives and platform architects, LiveKit’s traction with ChatGPT voice and safety‑critical users shows that buying specialized, managed stacks is becoming the default versus stitching open‑source components. Investors should watch consolidation and platform plays (M&A or IPO potential); product teams must evaluate vendor SLAs, edge strategies, and data flow into LLMs as they design voice features with production reliability and regulatory risk in mind.
