Astera Labs designs high-speed connectivity solutions for data center and AI infrastructure, enabling seamless integration of CXL, Ethernet, NVLink Fusion, PCIe, and UALink technologies through their COSMOS software suite. Their Intelligent Connectivity Platform addresses the critical bottleneck in AI clusters—connectivity—as GPU density scales from single nodes to thousand-GPU fabrics. The company offers a portfolio including Aries Smart Retimers, Taurus active electrical cable modules, Leo CXL Memory Controllers, and Scorpio X-series fabric switches, achieving 69% gross margins through a hybrid of premium hardware and high-margin software subscriptions.

Density uses proprietary depth sensors and AI-powered algorithms to anonymously count people in real-time across physical spaces. The platform helps organizations optimize building utilization, improve workplace efficiency, and enhance occupant experience without capturing personally identifiable information. Unlike camera-based solutions, Density's infrared depth sensing technology delivers 99% accuracy while maintaining privacy, making it the standard for workplace and real estate analytics.
