Astera Labs designs and sells semiconductor-based connectivity solutions for cloud and artificial intelligence infrastructure. The company's Intelligent Connectivity Platform comprises high-speed mixed-signal semiconductors (integrated circuits, boards, and modules) combined with COSMOS, an embedded software suite that enables configuration, management, and optimization of connectivity functions. The platform addresses data, network, and memory bottlenecks in hyperscale cloud and AI deployments through four primary product families: PCIe/CXL retimers, Ethernet smart cable modules, CXL memory controllers, and smart fabric switches. The company operates on a fabless model, outsourcing manufacturing to TSMC and assembly partners, and generates revenue by selling products directly to major hyperscalers and AI accelerator vendors as well as through distributors.
