Piris Labs: Cerebras-speed inference but scalable
Piris Labs is a Y Combinator-backed company that cerebras-speed inference but scalable. The company participated in the Winter 2026 batch of Y Combinator.
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.
Piris Labs was part of Y Combinator's Winter 2026 cohort, has a team of approximately 2 employees, and is actively operating.
