Paragraf

Paragraf is a University of Cambridge spinout founded in 2017 by Simon Thomas (CEO), Professor Sir Colin Humphreys, and Ivor Guiney. The company commercialises graphene and other two-dimensional materials at scale using standard semiconductor fabrication equipment, with a proprietary direct deposition technique that produces device-quality graphene on 8-inch wafers without metal catalysts or transfer processes. Paragraf launched its first product in 2019, a graphene-based Hall-effect sensor offering 30x greater sensitivity than conventional silicon at one-tenth the power. The sensor portfolio has expanded to include molecular sensors for healthcare, agritech, food production, and chemical manufacturing. The company has raised over £140M across four rounds, including a $55M Series C in 2025 led by Mubadala.
