The quest for "post-silicon" computing has reached a massive financial milestone today, January 29, 2026. Aramco Ventures has officially co-invested in a landmark $110 million Series A round for the Austin-based startup Neurophos, joining a high-profile syndicate led by Gates Frontier (Bill Gates' venture arm) and Microsoft’s M12. This investment marks a strategic pivot for the Saudi oil giant, moving from being a primary consumer of AI to owning the underlying hardware intellectual property. Neurophos is developing a revolutionary Optical Processing Unit (OPU) that uses photons (light) rather than electrons to process data, a shift that promises to be 100x more energy-efficient than today’s leading GPUs. By utilizing proprietary micron-scale metamaterial modulators that are 10,000 times smaller than traditional photonic elements, Neurophos has solved the "bulky" hardware problem that has long plagued optical computing. For Aramco, the stake in Neurophos is a key pillar of its "Vision...
