Xsight Labs

Xsight Labs is a fabless semiconductor company pioneering the rearchitecture of cloud infrastructure through fully programmable Ethernet switching and data processing solutions. Founded in 2017 by former EZchip engineers with decades of experience in networking silicon, the company has built a world-class R&D organization focused on solving the fundamental bottlenecks of modern data center architecture. Operating with offices across Israel, Armenia, and the United States, Xsight Labs addresses the critical challenge of exponential bandwidth growth in hyperscale cloud environments while simultaneously reducing the power and thermal footprint that constrains current infrastructure scaling. The company's flagship product portfolio—comprising the X1 fully programmable Ethernet switch (25.6Tbps/12.8Tbps), the second-generation X2 switch (12.8Tbps at less than 200W power consumption, representing 40% lower power than competing solutions), and the E1 software-defined DPU (800Gbps with 64 ARM Neoverse N2 cores)—delivers unprecedented programmability combined with application-specific optimization. Each product incorporates advanced architectural innovations including fully shared buffer systems for wire-speed in-cast performance, X-PND™ elastic resource allocation engines, fine-grained intelligent queuing (X-IQ™), comprehensive in-field health monitoring (X-Mon), and cutting-edge 5-nanometer silicon technology fabricated by TSMC. Xsight Labs' commitment to open-source architecture and industry collaboration is evidenced by its recent initiative to open the instruction set architecture (XISA) of its X-Series switches, challenging decades of vendor lock-in and enabling a thriving ecosystem of developers and system integrators.​ The company's customer base spans hyperscale cloud service providers, enterprise data centers, and next-generation AI infrastructure operators requiring best-in-class power efficiency, programmability, and performance for demanding distributed computing workloads. With a funding portfolio anchored by strategic investments from Intel, Microsoft, Xilinx, Valor Equity Partners, Atreides Management, and Fidelity Management & Research Company, Xsight Labs has established itself as a critical infrastructure innovator positioned to define the networking silicon paradigm for the AI era.
