7-8 West Newlands, Somersham, Cambridgeshire, PE28 3EB, United Kingdom

Overview

Paragraf develops graphene-based electronics and devices — including magnetic sensors and Graphene Molecular Sensors (GMS) — that integrate with standard semiconductor manufacturing processes. Its technology aims to deliver faster, more accurate, and lower-energy devices for extreme environments, from cryogenic quantum-computing systems to high-temperature, high-radiation industrial applications. Paragraf offers ready-to-use solutions and a platform for custom applications across healthcare, agritech, food production, chemical manufacturing, and consumer products. The company operates three facilities, two in Cambridgeshire, UK, and one in San Diego, US, following a 2023 acquisition. Paragraf is expanding its presence across the US, Europe, the Middle East, and Asia. The company recently completed a funding round intended to accelerate scaling and increase production capacity for commercial deployment of its graphene technologies. Paragraf develops commercial-quality graphene-based electronic devices using a contamination-free, scalable process that produces single-atom-thick, two-dimensional materials directly onto crystalline substrates such as silicon, silicon-carbide, sapphire and gallium-nitride. The technology is compatible with existing electronic device manufacturing processes. Its current product line includes a graphene Hall Effect Sensor range used across aerospace, semiconductor, healthcare, automotive, scientific research, industrial and quantum computing applications. The company is advancing a graphene-based biosensor targeted at transforming clinical point-of-care. Paragraf plans to use new funding to scale sales and technical capabilities in the UK, US, EU and Asia, boost R&D and product development capacity, and expand manufacturing infrastructure. The company has collaborated with CERN, the National Physical Laboratory and Rolls Royce and is led by CEO Dr Simon Thomas. Paragraf is a Cambridge, UK-based spin-out from the Centre for Gallium Nitride group at the University of Cambridge, led by CEO and co-founder Dr Simon Thomas. The company develops atom-layer-thick two-dimensional materials with a focus on graphene and holds an IP portfolio applying these materials to advanced electronic, energy and medical devices. Paragraf has achieved very early delivery to market of its first product, a super-high-sensitivity magnetic field detector. The detector offers operational capabilities over temperature, field and power ranges that no other device can currently achieve. The £3.4m Series A financing is intended to accelerate delivery of its first graphene-based electronics products to market. Paragraf, founded in 2015 as a University of Cambridge spin-out, develops graphene-based electronics and has built a manufacturing facility, graphene layer production and first device prototypes. Its first commercial product is a super-high-sensitivity magnetic field detector that the company says operates across temperature, field and power ranges unmatched by incumbents. The startup claims its IP-protected graphene technology can be produced using standard, mass-production scale manufacturing approaches and that its first sensors have shown order-of-magnitude operational improvements. Paragraf says it has strategic volume device production partners and is switching focus from development to product commercialisation. The company is transitioning into a commercial, revenue-generating phase supported by recent fundraising. CEO and co-founder Dr Simon Thomas stated the new funds will accelerate delivery and partnerships to bring devices to market. Paragraf has developed what it says is a novel, patent‑protected production technique intended to deliver functionally active graphene at commercial scale with improved uniformity, reproducibility, size and reduced contamination. Its core product focus is on producing atom‑layer thick 2D materials (starting with graphene) optimized for device‑specific applications, including sensitive detectors and improved contact layers for LEDs. The team claims the technique enables high quality and high throughput fabrication aimed at a new generation of electronic devices such as transistors, chemical and electrical sensors, and novel energy generation devices. Paragraf was spun out of Cambridge University’s Centre for Gallium Nitride group and, according to Crunchbase, was founded in 2015. The company closed a £2.9M (~$3.9M) seed round led by Cambridge Enterprise and intends to use follow‑on funding to scale development and deliver products from its IP pipeline. Management says it aims to deliver its first product by the end of the year and is planning a Series A raise expected in Q3 2019 to drive expanded development and product delivery.
