Luma Optics, a company specializing in AI optical interconnect hardware, has been named No. 47 on the 2025 Inc. 5000, 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 companies recognized. This achievement puts the company among past honorees including Microsoft, Meta, Chobani, and Patagonia.
The recognition comes at a critical juncture for the AI industry, as data center constraints have shifted from compute power to data movement. Frontier model training and inference are pushing GPU clusters beyond the capacity of copper interconnect. Luma Optics designs its AI optical interconnect hardware specifically for this environment, addressing bandwidth, latency, and thermal requirements that copper-based solutions cannot meet at scale. According to the company, every AI breakthrough now depends on how fast light can move between chips.
Eric Litvin, Co-Founder of Luma Optics, stated, "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."
Luma Optics has focused on the hardware profile required for large-scale AI deployments, including 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 500,000+ units shipped. The company's 5,757% three-year growth trajectory reflects documented design wins and repeat orders from operators running demanding compute infrastructure.
Founded in 2004 by Eric Litvin, Luma Optics has over two decades of experience in optical interconnect reliability, manufacturing process development, and deployment at scale. With operations in Sebastopol, California, and the Netherlands, the company serves both North American hyperscale customers and European sovereign AI programs.
