Piris Labs

Inference at Light Speed

Y CombinatorWinter 2026ActiveB2BInfrastructure

What they do

Problem

AI inference is bottlenecked by costly data movement and GPU memory limits, driving high latency and unsustainable unit economics for large models.

Solution

A full-stack inference service combining proprietary photonic hardware with a vertically optimized software stack to reduce the memory wall, improve FLOP utilization, and lower latency and cost.

Who it's for

AI model providers and enterprises deploying large-scale inference workloads (e.g., trillion-parameter models).

Keyvan Moghadam
Founder & President

I am an AI technologist with a decade of experience scaling AI/ML products. At Meta and X, I specialized in leading tiger teams to launch high-stakes 0-to-1 initiatives. Now, I am the Co-Founder of Piris Labs. We are building high-speed photonic interconnects to solve the energy and latency constraints for AI data inference. My current focus is to iterate on our inference service and onboard customers into our platform.
