Kandou AI vs LiveKit
Side-by-side comparison of AI visibility scores, market position, and capabilities
Semiconductor interconnect company; raised $225M from SoftBank and Synopsys at $400M valuation (March 2026); copper-based chip-to-chip PHY technology for AI accelerator clusters
About
Kandou AI is a semiconductor interconnect company that develops advanced chip-to-chip communication technology optimized for AI workloads. Founded by engineers with deep expertise in high-speed signaling, Kandou has pioneered copper-based interconnect solutions that deliver the bandwidth AI chips demand without the cost and complexity of optical alternatives. Its core technology addresses one of the most critical bottlenecks in AI hardware: efficiently moving massive amounts of data between processors, memory, and accelerators at high speed and low power.\n\nThe company's products focus on PHY (physical layer) and SerDes IP that can be licensed to chip designers and integrated into AI accelerators, networking ASICs, and memory subsystems. Kandou's interconnect solutions are designed to scale with next-generation AI training clusters where inter-chip bandwidth directly limits model training throughput. By solving the data movement problem with copper rather than optical, Kandou offers a cost-effective path to scaling AI infrastructure without the supply chain challenges of photonic components.\n\nIn March 2026, Kandou AI raised $225M from SoftBank and Synopsys at a $400M valuation, a significant vote of confidence from two of the semiconductor industry's most strategic investors. Synopsys's involvement is particularly notable given its dominance in EDA tooling and chip IP. The funding positions Kandou to expand its engineering team and accelerate licensing deals with major AI chip vendors as demand for high-bandwidth chip interconnects surges alongside GPU and NPU proliferation.
Real-time voice and video infrastructure powering ChatGPT Voice Mode, xAI, Meta, and Spotify; raised $100M Series C at $1B valuation in Jan 2026; open-source WebRTC platform specifically engineered for low-latency AI applications.
About
LiveKit is an open-source real-time audio and video infrastructure company providing the communication backbone for AI voice and video applications at scale. Founded to make production-grade real-time communication infrastructure accessible without the prohibitive cost and complexity of building it in-house, LiveKit developed a WebRTC-based platform optimized for the specific latency, reliability, and scale requirements of AI-powered voice and video experiences.\n\nLiveKit's platform handles the real-time transport layer for voice calls, video conferencing, and multimodal AI interactions — abstracting the complexity of WebRTC, TURN servers, codec optimization, and global distribution into a developer-friendly SDK. Its infrastructure is specifically engineered for the low-latency, high-reliability requirements of AI voice agents, where even 200ms of added latency degrades the conversational experience. The company provides SDKs for every major platform and has built a reputation as the most production-ready open-source option for real-time AI communication.\n\nLiveKit powers ChatGPT's Voice Mode, xAI's voice products, Meta, and Spotify — a client roster that validates its ability to operate at extreme scale and reliability. The company raised $100M in a Series C at a $1B valuation in January 2026, bringing total funding to $183M. As conversational AI products proliferate across consumer and enterprise applications, LiveKit's position as the de facto real-time infrastructure layer for AI voice gives it a durable and expanding role in the AI application stack.
