GigaIO, a California-based developer of scalable AI infrastructure solutions, announced it has raised $21 million in the first close of its Series B funding round, as it seeks to accelerate deployment of energy-efficient systems tailored for AI inferencing at scale.
The round was led by Impact Venture Capital, with additional backing from CerraCap Ventures, G Vision Capital, Mark IV Capital, and SourceCode Cerberus. GigaIO plans to use the funds to ramp production of its flagship SuperNODE and Gryf products, grow its sales and marketing footprint, and invest in new product development.
“We have created a new paradigm for cost-effective and power-efficient AI inferencing infrastructure,” said Alan Benjamin, CEO of GigaIO. “This funding allows us to meet growing market demand and empower customers with vendor-agnostic platforms that offer freedom from proprietary AI chip architectures.”
GigaIO’s core offering, built on its patented FabreX™ memory fabric, allows disaggregated computing by linking compute, GPU, storage, and networking into a unified system. The architecture enables organizations to dynamically scale infrastructure—at the rack level and beyond—offering flexibility and performance that traditional fixed-resource designs cannot match.
SuperNODE, the company’s rack-scale inferencing system, and Gryf, a suitcase-sized AI inferencing supercomputer designed for edge deployment, are central to GigaIO’s value proposition. Both products support a range of accelerators—including those from NVIDIA, AMD, Tenstorrent, and d-Matrix—giving users the ability to deploy AI workloads without being locked into specific chip vendors.
“GigaIO delivers a uniquely flexible, cost-effective, and energy-efficient solution that accelerates time to insight,” said Jack Crawford, Founding General Partner at Impact Venture Capital. “Their innovations meet the urgent need for scalable, real-time AI infrastructure in both enterprise and cloud environments.”
The funding comes as AI inferencing—processing trained AI models for real-world applications—emerges as a key challenge for enterprises, requiring infrastructure that is not only powerful but also energy- and cost-efficient.
GigaIO also announced plans for a second Series B close in the coming months, amid continued interest from strategic and institutional investors. Rockefeller Capital Management served as exclusive financial advisor for the transaction.
