Welcome back!

In this episode, Andreas Munk Holm sits down with Simon Thomas, CEO of Paragraf, one of Europe’s rare hard-tech success stories, taking graphene from scientific breakthrough to industrial-scale electronics.

Graphene has been called the “wonder material” for two decades. The promise has always been clear: faster, better, and dramatically more energy-efficient electronics. The missing piece has been execution at scale. Simon and the Paragraf team are building that missing bridge, with the world’s first graphene electronics foundry in the UK, a growing portfolio of real commercial products, and a deep conviction that the next era of computing will require new materials, not just bigger data centers.

This is a conversation about what it truly takes to build venture-backed hardware in Europe.

How you fund capex-heavy deep tech.
How do you keep investors aligned when timelines are long.
How you keep teams motivated through delays and national security reviews.

And why AI may accelerate materials discovery, but won’t replace the brutal, necessary work of turning atoms into real manufacturing.
