Luma Optics, a manufacturer of AI optical interconnect hardware, announced it has been ranked No. 47 on the 2025 Inc. 5000 list, Inc. magazine's annual ranking of the fastest-growing private companies in America. The ranking is based on 5,757% three-year revenue growth, placing Luma Optics in the top 1% of all 5,000 recognized companies and among past honorees including Microsoft, Meta, Chobani, and Patagonia.
The recognition comes at a critical juncture for the AI industry. As frontier model training and inference push GPU clusters beyond the capacity of copper interconnect, the constraint inside data centers has shifted from compute power to data movement. Luma Optics designs its hardware specifically for this environment, addressing bandwidth, latency, and thermal requirements that copper-based solutions cannot meet at scale.
"Every AI breakthrough now depends on how fast light can move between chips," said Eric Litvin, Co-Founder of Luma Optics. "We built Luma for this exact moment. Ranking No. 47 on the Inc. 5000 isn't a vanity milestone - it's a signal that the market has decided optical is the only path forward for heavy AI, and that Luma is executing against that reality faster than anyone else."
While much of the optics industry continues to operate within legacy telecom form factors, Luma Optics has focused on hardware profiles tailored for large-scale AI deployments: heavy-workload optimization for training clusters and inference fabrics, higher bandwidth density per rack unit than competing solutions, lower power draw per bit to address energy constraints facing hyperscalers, and production-grade reliability with a field failure rate under 0.01% across more than 500,000 units shipped.
The 5,757% three-year growth trajectory reflects documented design wins and repeat orders from operators running some of the most demanding compute infrastructure in production today. Luma Optics was co-founded by Eric Litvin in 2004, giving the company over two decades of experience in optical interconnect reliability, manufacturing process development, and deployment at scale. With operations in Sebastopol, California, and the Netherlands, Luma Optics serves both North American hyperscale customers and European sovereign AI programs.
Companies are ranked by percentage revenue growth over a three-year period for the Inc. 5000, which is the most recognized ranking of the nation's fastest-growing private companies.
