Mass-produced graphene sensors for the semiconductor industry.
About Paragraf
Paragraf is a deep-tech company revolutionizing the electronics industry by enabling the mass production of graphene-based devices. A 2017 spin-out from the University of Cambridge, the company was founded by Professor Sir Colin Humphreys, Dr. Simon Thomas, and Dr. Ivor Guiney, who collectively leveraged their extensive expertise in materials science and semiconductors to overcome a long-standing challenge in electronics: producing high-quality graphene at scale. The breakthrough came from a proprietary and scalable method of depositing large-area, device-quality graphene directly onto semiconductor wafers, a process compatible with existing manufacturing infrastructure. Paragraf's business model is centered on the design, development, and manufacturing of these advanced electronic components, serving as both a product provider and a foundry service for custom 2D material applications. Paragraf's primary revenue stream comes from the sale of its graphene-based sensors and its funding rounds, having raised significant capital to scale its operations. Its clientele spans various high-tech sectors, including automotive, healthcare, quantum computing, aerospace, and industrial automation. Paragraf's investors include Amadeus Capital Partners, British Patient Capital, and In-Q-Tel, a venture capital firm associated with the CIA. Paragraf's product portfolio includes Graphene Hall Sensors (GHS) and Graphene Molecular Sensors (GMS). The GHS line offers exceptionally high sensitivity and performance in extreme conditions, such as cryogenic temperatures and high magnetic fields, making them ideal for quantum computing and electric vehicle (EV) battery management. The GMS products are electrolyte-gated field-effect transistors that provide rapid and precise detection of molecules, ions, and gases. These biosensors have applications in medical diagnostics for early disease detection, environmental monitoring, and agritech. The core benefit of Paragraf's technology is that its devices perform faster, more accurately, and with lower energy consumption compared to traditional silicon-based alternatives.
