Upscale AI has closed a $200 million Series A financing round led by Tiger Global, Premji Invest, and Xora Innovation. The oversubscribed round included participation from Maverick Silicon, StepStone Group, Mayfield, Prosperity7 Ventures, Intel Capital, and Qualcomm Ventures. The fresh capital brings total funding to over $300 million, propelling the company to unicorn status just months after raising a $100 million seed round.

The rapid investor backing signals a broader industry shift. Networking has become a critical bottleneck for AI systems, and traditional network architectures built for general-purpose compute can’t handle the demands of modern AI workloads. Legacy data center networks were designed to connect endpoints, but AI requires something fundamentally different: unified clusters that synchronize massive amounts of specialized compute at rack scale.

Why Traditional Networking Can’t Keep Up with AI

The problem is structural. Traditional networking connects separate systems, while AI networking needs to unify entire clusters into synchronized engines. As specialized AI accelerators continue to scale, they’re increasingly held back by retrofitted or proprietary networking solutions that weren’t designed for this purpose.

Upscale AI was built from the ground up to address this challenge. The company’s approach centers on unifying GPUs, AI accelerators, memory, storage, and networking into a single synchronized system rather than treating them as separate components connected by cables.

Platform Built on Open Standards

The company’s SkyHammer scale-up solution serves as the core of this strategy. By collapsing the distance between accelerators, memory, and storage, SkyHammer transforms the entire infrastructure stack into one cohesive system. The platform is built on open standards and open source technologies, including ESUN, Ultra Accelerator Link (UAL), Ultra Ethernet (UEC), SONiC, and the Switch Abstraction Interface (SAI).

Upscale AI actively participates in the Ultra Accelerator Link Consortium, Ultra Ethernet Consortium, Open Compute Project, and SONiC Foundation. This commitment to openness differentiates the company from proprietary alternatives that lock customers into single-vendor ecosystems.

Funding to Accelerate Commercial Deployment

The $200 million will fund rapid expansion across engineering, sales, and operations as the company moves into commercial deployment. Upscale AI is already seeing strong early demand from hyperscalers and AI infrastructure operators looking for scalable, open networking alternatives to proprietary solutions.

The company plans to ship its networking solutions later this year. The timeline reflects both the urgency of market demand and the team’s experience in building and deploying infrastructure at scale.

“This investment accelerates our mission to fundamentally re-architect networking for the AI era. With a world-class team and strong customer pull, we have a once-in-a-generation opportunity to build the open AI networking platform the industry has been waiting for.”

Who’s Behind Upscale AI

Upscale AI was founded to solve what its leadership team identified as the most pressing infrastructure challenge in AI. The company is led by CEO Barun Kar and Executive Chairman Rajiv Khemani, both of whom bring deep experience in building and scaling infrastructure systems.

The company’s ability to attract over $300 million in funding within months reflects both the scale of the opportunity and investor confidence in the team’s execution capabilities. The rapid fundraising trajectory is unusual even in the well-funded AI infrastructure space.

Why Investors Are Backing Upscale AI

Investors see networking as the next major infrastructure challenge for AI systems. As models grow larger and training clusters expand, the ability to move data efficiently between accelerators becomes as important as raw compute power.

“AI is fundamentally reshaping infrastructure, and networking is at the center of that transformation,” said Rohit Iragavarapu, Partner at Tiger Global. “Upscale AI combines deep technical execution with strong industry relationships to build the next generation of AI networking.”

Premji Invest’s thesis centers on the team’s proven track record and technical approach. “As AI systems scale, interconnect efficiency has become a defining driver of performance and economics—not just raw compute,” said Sandesh Patnam, Managing Partner at Premji Invest. “What stands out about Upscale AI is not only their purpose-built approach to scale-up networking silicon, but the depth of experience of a team that has successfully built and deployed this class of infrastructure before.”

Market Opportunity and Validation

Multiple investors highlighted the timing of Upscale AI’s market entry. The company is launching as demand for AI networking infrastructure accelerates and enterprises seek alternatives to proprietary solutions. Maverick Silicon, which participated in both the seed and Series A rounds, noted the company’s execution speed since the initial investment.

StepStone Group emphasized customer traction as a key factor in their investment decision, expecting the team to translate early momentum into deployments with leading hyperscalers and AI infrastructure operators. Intel Capital and Qualcomm Ventures both pointed to scalability and enterprise adoption as key drivers, with Upscale AI’s open, turnkey approach removing complexity from networking infrastructure.

Industry analysts see significant market potential for AI networking solutions. According to 650 Group, AI networking is on track to become a $100 billion annual market by the end of the decade. Dell’Oro Group identified the networking market as reaching a clear inflection point with AI, calling Upscale AI’s SkyHammer architecture one of the most important developments to watch.

AMD highlighted the importance of Upscale AI’s commitment to open standards, noting that by adopting UALink early, the company is helping to foster an ecosystem centered on openness, choice, and interoperability.
