About

LiveKit builds open-source SDKs and a cloud platform for developing, deploying, scaling, and observing real-time voice, video, and physical AI agents. It sells primarily to developers and teams, including AI and robotics labs and Fortune 500 companies, differentiating through low-latency global infrastructure, native telephony, broad model integrations, and end-to-end observability.

Market

LiveKit competes in realtime communications and AI-agent infrastructure, positioning itself as an end-to-end developer platform for building, deploying, and observing voice, video, and physical-AI applications. It differentiates through open-source SDKs, low-latency global media infrastructure, native telephony, broad model-provider support, and enterprise security and compliance features, rather than offering only communications APIs or UI components.

Target Customers

LiveKit primarily serves developer teams building production voice, video, and physical-AI applications, including AI and robotics labs, fast-growing technology companies, and Fortune 500 enterprises. Its buyers and users are engineering teams, platform teams, and product developers that need to build, deploy, scale, and observe realtime AI agents.

At a Glance

Problem

Building reliable, real-time voice, video, and physical AI applications is difficult because developers must solve low-latency media transport, unstable-network behavior, model integration, turn-taking, telephony, capacity management, load balancing, and failover at the same time. LiveKit’s core pain point is the gap between an impressive AI prototype and a production system that can handle large volumes of live interactions without forcing every company to become a communications-infrastructure operator. The economics are primarily engineering time, operational complexity, and infrastructure risk: scaling agents requires specialized handling of connections, capacity, change management, and failure recovery.

The killer use case is production voice AI, especially customer-service and call-center agents that can handle inbound and outbound phone conversations. Other applications include telehealth, real-time translation, multimodal assistants, and robotics, but customer support is the clearest high-volume case because every successful interaction can automate or augment a live human conversation across web, mobile, or the telephone network.

Product / Service

LiveKit provides an open-source framework and a managed cloud platform for building, testing, deploying, scaling, and observing real-time AI agents. Developers can write agents in Python or Node.js, add them to LiveKit rooms as full real-time participants, connect them to LLM, speech-to-text, and text-to-speech providers, and deploy them either on LiveKit Cloud or in a custom environment. WebRTC handles the live connection between the user and agent, while LiveKit supplies the surrounding infrastructure, including agent orchestration, load balancing, scaling, telephony, SIP, and observability.

The delivery model combines open-source adoption with paid cloud infrastructure. The open-source framework reduces the complexity and lock-in associated with building a real-time media layer from scratch, while LiveKit Cloud offers turnkey deployment on a global network for teams that want production operations handled for them. The result is a developer platform intended to make deploying a voice or multimodal agent closer to deploying a conventional web application than operating a communications stack.

Market

LiveKit competes at the intersection of real-time communications infrastructure, WebRTC media servers, developer platforms, and voice-AI agent runtimes. In the broader communications layer, alternatives include 100ms, Agora, Daily, Twilio Video, Amazon Chime SDK, VideoSDK, and Jitsi. In voice-AI development, the competitive set includes Pipecat, Vapi, Retell, and Daily Bots; SignalWire is another adjacent competitor, with a more telecom-centric architecture and its own SIP/PSTN infrastructure.

LiveKit is clearly beyond a pre-revenue experiment in adoption and financing, although the available evidence does not establish revenue. Its site says more than 300,000 developers and teams use LiveKit, including AI and robotics labs and Fortune 500 companies, while the company says its network handles billions of calls annually. It also lists production usage by companies including OpenAI, Headspace, Decagon, Skydio, Tesla, Zocdoc, xAI, Oracle, Retell, Nvidia, Spotify, Cresta, Salesforce, and Whatnot. In January 2026, LiveKit announced a $100 million Series C at a $1 billion valuation, indicating substantial investor confidence in the voice-driven computing market and in LiveKit’s position as infrastructure for it.
