Paragraf Closes $55M Series C Funding Round

September 2, 2025

Paragraf, the UK-based company leading the way in mass-producing graphene-based electronics using industry-standard semiconductor processes, has completed a $55m Series C funding round.

The funding will accelerate scaling of Paragraf’s manufacturing capabilities and boost production output to enable the adoption of graphene electronics in mass markets. Paragraf’s technology integrates seamlessly with the established semiconductor ecosystem, providing customers with ready-to-use solutions and the platform on which to develop bespoke applications tailored to their needs.

Graphene’s unique properties enable devices to perform faster, more accurately and with lower energy consumption than silicon-based alternatives — especially in extreme environments, from cryogenic systems in quantum computing to high-temperature and high-radiation applications in an array of industries. In molecular sensing, Paragraf Graphene Molecular Sensors (GMS) are being used to produce liquid and gas sensors for the early detection of disease and use in various other healthcare, agritech, food and chemical manufacturing, and consumer solutions. Graphene-based technologies are opening new possibilities across a range of sectors.

Dr Simon Thomas, Co-Founder and CEO of Paragraf, said: “This investment is a strong signal of confidence in Paragraf and our mission in the face of global economic uncertainty. This new funding will enable us to expand production of faster, more energy-efficient technologies to the scale required by major commercial opportunities. In what is a particularly challenging funding environment, we’ve attracted strong interest and are pleased to have secured the backing of both new and existing partners who share our vision for transforming electronics with graphene.”

About Paragraf

Some of Paragraf’s investors include Amadeus Capital Partners, British Patient Capital, Cambridge University, IQ Capital, IQTI LLC, Martlet Capital Ltd, Molten, Mubadala Capital, New Science Ventures, Openfield Capital, and Parkwalk Advisors (IP Group).

Founded in 2015, Paragraf is pioneering the development and commercial adoption of graphene-based electronic devices using industry-standard semiconductor processes.

With lines of magnetic sensors and GMS already in production, and other advanced semiconductor devices in development, Paragraf’s proprietary graphene growth process unlocks the full potential of this remarkable material.

The company operates three facilities — two in Cambridgeshire, UK, and one in San Diego, US, following the rare 2023 acquisition of a US-based company by a UK scale-up. Paragraf now has a growing footprint throughout the US, Europe, the Middle East and Asia.
