Lumai Raises More Than $10M in Funds, Brings its Optical Processing Breakthrough Forward to Address Limitations of AI Compute

Lumai, an AI accelerator startup using optics to address global computational challenges, announced that it has secured more than $10 million in a recent investment, enabling AI data centers to dramatically reduce costs and boost performance—while simultaneously minimizing energy consumption.

The round was led by VC investor Constructor Capital, which works with visionary founders building ground-breaking companies across the deep tech sector. It was also supported by existing investor IP Group, alongside new investors PhotonVentures, Journey Ventures, LIFTT, Qubits Ventures, State Farm Ventures, and TIS Inc.

According to the company, Lumai will use this investment to support its next stage of growth—advancing product development, doubling its headcount, and expanding its U.S. presence.

Spun out of the University of Oxford, Lumai is tackling the limitations of AI compute by using optical processing to accelerate large language models (LLMs) and other transformer-based AI.

Lumai has succeeded where others have failed, overcoming the scalability challenges of optical computing. Its technology processes AI’s core arithmetic operations within optical beams traveling through 3D space, bypassing the limits of silicon GPUs and integrated photonics, the company said.

“The future of AI demands radical breakthroughs in computing. The cost of current LLMs is unsustainable, and next-generation AI won’t happen without a major shift. Lumai’s innovative optical computing design overcomes the scalability challenges that have held others back and dramatically reduces power consumption, which will drive down the cost of AI,” said Tim Weil, CEO and co-founder at Lumai.
