Company profile
researched Aug 2026LiveKit provides an open source framework and developer platform for building realtime AI agents that interact with users through voice, video, and robotics interfaces. The stack covers agent development and testing, an inference gateway for accessing speech-to-text, text-to-speech, and large language model providers, cloud deployment and scaling of agents, telephony via phone numbers and SIP integrations, and full-stack observability for agent sessions.
In a typical LiveKit deployment, a user speaks to an agent through a web app, mobile app, browser, or phone call; the speech is streamed from the device to the agent, which runs the developer's custom business logic and responds back to the user. The platform advertises automatic turn detection and interruption handling, support for millions of concurrent calls, and SDKs including Python and Node.js, with quickstart paths for voice agents, starter web and mobile apps, telephony integration, and deployment to LiveKit Cloud.
Business model
LiveKit combines an open source agents framework with a commercial hosted offering, LiveKit Cloud, which runs and scales customer agents on LiveKit's global realtime infrastructure and provides related services such as model inference access, telephony phone numbers and SIP connectivity, and session observability.
Traction
The company reports powering billions of calls in production annually, a developer community numbering in the thousands, and multi-region global infrastructure. Named customers and referenced users include OpenAI (ChatGPT Advanced Voice built on LiveKit Cloud), Podium, Retell AI, Playback, Assort Health, Spara, and robotics company Polymath.

Market position
LiveKit positions itself as the complete stack for voice AI, citing use by OpenAI for ChatGPT's Advanced Voice mode, more than 2.5 billion calls annually on its platform, and enterprise compliance attestations covering GDPR, SOC 2 Type 2, and HIPAA.
LiveKit emphasizes model-agnostic flexibility and granular control over agent code with any model provider, combined with managed scaling and production-ready realtime infrastructure, so teams can avoid maintaining their own realtime stack while retaining customization.
Technology
Core technology covers realtime audio and video transport and agent orchestration. The agents framework composes pipelines from third-party models (examples cited include Deepgram speech-to-text, Google LLMs, and Cartesia text-to-speech) together with a multilingual turn-detection model for automatic end-of-turn detection and interruption handling. Client and server SDKs are offered for Python and Node.js, alongside web and mobile app starter kits and SIP-based telephony integration.
Go-to-market
Developer-led distribution through an open source framework, public documentation, quickstart guides and starter apps, GitHub presence (livekit/agents), and educational content, including a course on building AI voice agents for production created in collaboration with LiveKit and taught in part by its co-founder and CEO; commercial conversion occurs via LiveKit Cloud.
Developers and engineering teams building voice AI, video AI, and robotics applications, ranging from startups to large enterprises, including healthcare, sales and go-to-market, and robotics use cases.
Geography
LiveKit Cloud lists regional infrastructure across Australia, Brazil, Canada, France, Germany, India, Israel, Japan, Saudi Arabia, Singapore, South Africa, the UAE, and multiple United States regions (US Central, US East, US West).
