- GigaIO
Participated · Series B · Jul 2025
GigaIO is a Carlsbad, Calif.–based provider of scalable infrastructure designed for AI inferencing, with flagship products SuperNODE and Gryf. Its platform is built on the company's patented FabreX AI memory fabric, which enables scale-up and dynamic composition of compute, GPU, storage, and networking resources for ultra-low latency, memory-to-memory communication between GPUs. SuperNODE is positioned as a cost-effective, energy-efficient scale-up AI computing platform, while Gryf is described as a suitcase-sized AI inferencing supercomputer for edge deployment. GigaIO plans to ramp production of SuperNODE, accelerate deployment of Gryf, invest in new product development, and expand sales and marketing to meet surging demand. The company emphasizes a vendor-agnostic architecture that supports GPUs from NVIDIA and AMD as well as emerging AI chips, aiming to free customers from single-source vendor lock-in. Management says these capabilities unlock performance and cost efficiencies as AI models grow larger and more complex and enable scaling at the rack level and beyond. GigaIO develops an enterprise-class universal composable fabric, FabreX, that configures and orchestrates networking, storage, memory, and specialized accelerators into a single-system cluster fabric for AI and HPC workloads. Its rack-scale architecture lets workloads run as if using components inside one server while harnessing many nodes, improving utilization and reducing server, cooling, power, and footprint costs. The company positions FabreX as an open-standards PCIe-based solution and plans to extend to PCIe Gen5 and CXL to enable pooled memory and shared accelerators. GigaIO intends to use the new funding to aggressively expand market and channel development, recruit more partners, and devote resources to customer and partner development programs to accelerate sales and marketing. Financially, GigaIO completed an oversubscribed Series B raising $14.7 million led by Impact Venture Capital, with participation from Mark IV Capital, Lagomaj Capital, SK Hynix, and Four Palms Ventures. Founded in 2012, the company launched its first product line in 2019 and has been commercializing its fabric under CEO Alan Benjamin, who joined in 2017. GigaIO offers the GigaIO Fabrex™ platform, a patented interconnect network that delivers low latency and high bandwidth for data center connectivity. Its technology enables bare-metal disaggregation of hardware into dynamically reconfigurable resource pools, improving flexibility, utilization and cost reduction. That architecture allows data centers to scale up or out performance while preserving existing investments and adding new capabilities. The company is led by CEO and president Alan Benjamin and is based in Carlsbad, CA. GigaIO closed a $4.5M Series A to accelerate product development and expand sales and marketing. Management planned availability of the platform in Q4 2018.
