Upscale AI has secured a major early-stage funding round as investors continue to bet on networking as one of the most critical constraints in scaling artificial intelligence infrastructure. The company announced it has raised $200 million in Series A financing.
The size and speed of the raise reflect a growing consensus across the AI infrastructure ecosystem that traditional data center networking is increasingly ill-suited to modern AI workloads.
The funding round was led by Tiger Global, Premji Invest, and Xora Innovation, with additional participation from Maverick Silicon, StepStone Group, Mayfield, Prosperity7 Ventures, Intel Capital, and Qualcomm Ventures. Including earlier funding, Upscale AI has now raised more than $300 million.
As AI systems scale, particularly at the rack level, performance bottlenecks are shifting away from compute alone toward the ability to move data with extremely low latency and tight synchronization. Conventional network architectures, designed to connect independent endpoints such as servers and storage, struggle to support the highly coordinated, scale-up environments required by large AI clusters.
Upscale AI was founded with the explicit goal of addressing this architectural mismatch. Rather than treating networking as a connective layer, the company positions it as a core component of the AI system itself. Its approach aims to unify GPUs, accelerators, memory, storage, and networking into a single, synchronized platform, enabling AI infrastructure to behave more like a cohesive engine than a collection of loosely coupled parts.
At the center of Upscale AI’s strategy is its SkyHammer scale-up solution, which is designed to collapse the distance between accelerators, memory, and storage within a rack. By reducing latency and improving synchronization across heterogeneous components, the platform targets workloads that demand extreme coordination, including advanced training and emerging artificial general intelligence research. The company’s technology stack is built around open standards and open-source technologies such as Ultra Accelerator Link, Ultra Ethernet, SONiC, and the Switch Abstraction Interface, reflecting an effort to provide an alternative to proprietary, closed networking ecosystems.
Upscale AI is also actively involved in industry groups shaping the future of AI and data center networking, including the Ultra Accelerator Link Consortium, Ultra Ethernet Consortium, Open Compute Project, and SONiC Foundation. This participation underscores its emphasis on interoperability and vendor-neutral architectures, which many hyperscalers and AI infrastructure operators increasingly view as essential to long-term scalability.
With the new funding, Upscale AI plans to accelerate hiring across engineering, sales, and operations as it moves toward commercial deployment. The company says it is seeing early traction among hyperscalers and large AI infrastructure providers looking to move beyond retrofitted legacy networks. Its networking solutions are expected to begin shipping later this year, marking the transition from development to market delivery.
According to CEO Barun Kar, the investment supports a broader effort to rethink networking for AI from first principles. Executive Chairman Rajiv Khemani added that customer demand for open, scalable AI networking has intensified as organizations confront the limits of existing architectures. As AI systems continue to grow in size and complexity, Upscale AI’s bet is that networking will become a defining layer in next-generation compute platforms.
