Nicolas Muller

Nicolas Muller is the co-founder and CEO of Arago, a Paris-based deep-tech startup building a photonic AI accelerator called JEF that uses light instead of transistors to perform AI inference at 10x lower energy than leading GPUs. Coming from a physics and machine learning background - including an ML degree from MIT - Muller co-founded Arago in 2024 alongside Eliott Sarrey and Ambroise Müller. The company raised an oversubscribed $26M seed round in July 2025 backed by Earlybird, Protagonist, Visionaries Tomorrow, and angels from Apple, Datadog, Hugging Face and Arm. Arago's approach - top-down from inference efficiency requirements, not bottom-up from optics research - delivered a working prototype in under 12 months.
