About Piris Labs
Summary
Piris Labs builds a full-stack AI inference service that pairs proprietary photonic hardware with a vertically optimized software stack. The system targets the memory bandwidth bottleneck that makes large-model inference expensive on GPU clusters, delivering comparable throughput at lower cost. B2B customers running trillion-parameter models get the same performance without the unit economics that make GPU-based inference unsustainable at scale.
Business model
A fraction of the cost of traditional GPU cluster inference, priced as a service.
Go-to-market
Piris Labs sells to B2B customers running large-scale AI inference workloads, positioning its service as a direct replacement for GPU cluster deployments.

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.
