About Paragraf

Paragraf is the first company in the world to unlock the impressive atomic properties of graphene by solving the contamination challenge. We are the only company able to produce pristine, undamaged, contamination-free graphene, thanks to our proprietary MOCVD process, and our UK foundry.

To demonstrate, facilitate & support our customers’ research, development and commercialisations of graphene applications, we have developed graphene-based electronic devices using standard semiconductor processes. Our Graphene Hall Sensors (GHS) and Graphene Field-Effect Transistors (GFETs) currently in production, and other devices in development, make use of our proprietary graphene growth process to fully harness the wonder material’s myriad features. Our products deliver superior sensitivity, robustness and energy efficiency to solve important problems in a range of applications, including medtech, environmental monitoring, agritech and more.

At Paragraf we are committed to materially impacting critical global challenges by driving a 2D-material revolution in the semiconductor industry, which we believe will facilitate massive improvements in the performance of technologies across all aspects of life.

A spin-off from the University of Cambridge in 2018, Paragraf has raised $150 million over four rounds of fundraising and is widely recognised as an emerging tech leader.
