Astera Labs
Astera Labs (ALAB) is a publicly traded Networking & Custom Silicon company founded in 2017 and based in San Jose, USA.
Founded in 2017 and headquartered in San Jose, CA, Astera Labs builds the 'connective tissue' inside AI infrastructure: its Aries PCIe/CXL Smart Retimers extend signal integrity across long PCIe 5/6 channels and cable runs; its Taurus Active Electrical Cables push 800G Ethernet between switches and NICs with full NVIDIA Spectrum-X interoperability; its Leo CXL Smart Memory Controllers enable CXL memory pooling (deployed on Microsoft Azure M-Series in 2025); and its Scorpio Smart Fabric Switch family — scaling from 32 to 320 lanes — provides open, memory-semantic scale-up interconnect for large GPU clusters. The company went public on NASDAQ in March 2024 (ticker: ALAB), raising roughly $713 million at a ~$5.5B implied valuation, and reported record full-year 2025 revenue with all four product families growing. Founders Jitendra Mohan, Sanjay Gajendra, and Casey Morrison were named EY World Entrepreneur Of The Year 2026.
As AI clusters scale to tens of thousands of accelerators, PCIe, CXL, and fabric bandwidth become the binding constraint — Astera Labs is one of the few pure-play fabless companies with a full-stack of shipping silicon specifically engineered for that bottleneck, across every major hyperscaler.
