Inference at Light Speed

Piris Labs offers a full-stack inference service that eliminates the AI data movement bottleneck. By pairing proprietary photonic hardware with a vertically optimized software stack, we minimize the "memory wall" associated with expensive GPUs. This allows us to deliver the same performance as traditional clusters at a fraction of the cost. Our technology improves effective FLOP utilization and reduces latency, finally making the unit economics of trillion-parameter models sustainable. Founded by a team of MIT physicists and Meta AI experts.

Founder & President
I am a technical leader 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 in AI data centers. My current focus is delivering our E/O engine prototype to secure our seed round.

The Problem: The Memory Wall Is Breaking the Economics of AI Compute

AI’s promise is unprecedented, but its economics are broken. Copper-based interconnects cannot keep up with modern models, limiting data movement between and within compute and memory. The result is high latency, inefficient hardware utilization, and unsustainable inference costs—creating a hard ceiling on AI margins.


The Solution: Grow-Style Optimization for the Interconnect

Today’s data-center compute and networking were not designed for inference. Slow, power-hungry copper interconnects, along with costly signal processing and memory overhead, drive high latency and high cost.

High-performance inference requires purpose-built hardware and a vertically optimized software stack. Piris Labs builds this optimized stack by combining proprietary optical interconnects with software designed to maximize hardware utilization. We vertically optimize the interconnect layer—just as the compute layer was vertically optimized by Groq (acquired by NVIDIA for $20 B).

Piris Labs combines proprietary optical interconnects with a purpose-built software stack designed to maximize hardware utilization, delivering 5x lower latency, 10x lower power per bit, and 2x lower cost per token
