Purpose Built from the ground-up for scale-up
SkyHammer supports emerging
scale-up interconnect standards
such as ESUN, UEC, UALink
while adaptable to future
innovations.
AI Demands. Sky Delivers.
The Future of AI Networking Isn’t Proprietary. It’s Open.
At Upscale, we’re not just supporting standards, we’re helping shape them. Upscale AI is an active member of leading open standard consortiums UEC, UAL, and SONiC. Through our active role in these consortiums, we are helping shape how AI systems scale with openness, interoperability, and performance at the core.

AI infrastructure is entering a phase where traditional data center fabrics can no longer keep pace with the scale and synchronization AI demands. Upscale AI’s SkyHammer architecture represents a decisive step toward purpose- built, open, and predictable interconnects that are designed for AI from the ground up. This approach aligns closely with what we see as the next major shift in data center networking, one where openness, determinism, and scalability define the winners.
With AI compute demands exploding, the industry urgently needs open, scalable, and cost-efficient solutions; SkyHammer is a step squarely in that direction.
The AI era demands infrastructure that is open, efficient, truly scalable, and economically sustainable. Upscale AI’s SkyHammer marks a pivotal move toward that vision, speeding up innovation and democratizing AI through the stack, bridging a key gap in today’s high-performance AI landscape.
Celesta is incredibly proud to continue to back and partner with Rajiv Khemani, Barun Kar and the incredible team at Upscale.
From enterprise networking to building cloud infrastructure, Upscale AI’s team has been at the center of every major computing shift over the past 20 years.
Founded by Barun Kar (CEO) and Rajiv Khemani, Upscale AI leverages open-standard networking technology to drive innovation across AI infrastructure.
The startup’s network brings together a host of different open standards, enabling complete freedom of choice for data center operators.
Many industry-leading tools remain trapped within closed-circuit vendor-locked systems, but Upscale AI is building a level playing field where innovation, performance, and healthy competition can thrive.
They’re reimagining the entire AI networking stack, starting with scale-up solutions for connecting GPUs based on open standards that break free from proprietary systems.
