XCENA, a startup building computational memory solutions based on the Compute Express Link (CXL 3.x) standard, announced a $135M Series B funding round on May 29, 2026. The round was co-led by Atinum Investment and IMM Investment, bringing total funding to $185M at a $570M valuation. The company will use the funds to scale deployments of its MX1 product, which merges pooled DDR5 memory with near-data processing to reduce AI data bottlenecks. This significant investment signals strong investor confidence in CXL-based architectures for AI infrastructure. Additionally, the CXL consortium released the CXL 4.0 specification (up to 128 GT/s) in November 2025, further solidifying the standard's roadmap. The combination of a well-funded startup and advancing standards indicates growing momentum for CXL adoption in hyperscale data centers.
