Two Stanford physicists left the lab to fix a broken system: computer chips that waste too much energy and can’t keep up with AI.

Their startup, Lightium, is using light (yep, actual light) to make chips faster, cooler, and ready for the next tech wave — from AI to quantum.

In this episode, we get into:
- Why traditional chips are hitting a ceiling
- How they explained photonic tech without losing the room
- The inside story of raising €7M as deeptech outsiders
- What it really takes to turn hard science into a real business
