Dr Simon Thomas never expected to be a founder. After 12 years inside TSMC, Samsung and LG, he was ready for a break from the pressure of the world’s biggest fabs. Then Professor Sir Colin Humphreys set him a challenge: could he make graphene at wafer scale – the same problem Samsung had spent $2.2 billion trying, and failing, to crack?

Five weeks of experiments later, Simon saw the first promising result. A short time after that, Paragraf was born, and by December 2024 the company had switched on the world’s first graphene electronics foundry.

In this episode of Lab to Market Leadership, Simon explains how a decade‑plus in Asian fabs gave him a process‑engineering lens no one else brought to graphene, how a chance train journey with Colin Humphreys became the turning point, and why copper‑free, transfer‑free graphene was essential to escape the industry’s 'trough of disillusionment.'

He also talks candidly about the hardest part of scaling a Deep Tech company: people. From hiring the first team to recognising when someone’s journey with the company is over, and from open‑door collaboration to faster, tougher CEO calls, this is essential listening for technical founders learning to lead as CEOs.
