## About

Based in Scotland, UK, founded in 2016 iGii is dedicated to creating innovative carbon nanomaterials for advanced sensing. The company is co-founded by Claus Marquordt and Marco Caffio. Currently, Jean-Christophe Granier serves as the CEO as of 2026. In September 2026, iGii raised EUR 13.65 million in series B funding led by Scottish National Investment Bank, with participation from other PXN Group, Techstart Ventures, ESM Investments and Archangels Investors Limited. The round was a part of a larger EUR 26.49 million in Series B and Grant funding.

iGii specializes in the development and manufacturing of Gii, a pure 3D carbon nanomaterial designed for advanced sensing technologies across various industries. Gii is characterized by its exceptional carbon purity, large surface area, and anti-fouling properties, enabling it to outperform traditional materials such as gold, platinum, and graphite in terms of sensitivity and cost-efficiency. The company's flagship offering includes a proof-of-concept sensing platform that demonstrates Gii’s capabilities in applications like point-of-care human diagnostics, environmental monitoring, veterinary diagnostics, soil health monitoring, and food safety. These products are aimed at diverse end-users, including healthcare professionals, environmental agencies, agriculture producers, and food safety regulators. iGii's technology is marketed primarily in Europe and North America, focusing on sectors where accuracy, scalability, and sustainability are paramount.

iGii generates revenue through direct sales of their Gii-based products and potential partnerships with entities in healthcare, environmental management, and agricultural sectors. The company structures its transactions through B2B relationships, engaging directly with clients who require advanced diagnostic and monitoring solutions. While specific pricing plans for individual products are not disclosed, the business model is centered around transactional sales agreements for the Gii sensing platform and associated services, which may include ongoing support and maintenance. The revenue model leverages strategic partnerships to enhance market penetration and scalability, particularly in high-demand applications such as health diagnostics and environmental assessments. Additionally, recent funding initiatives, such as the GBP 8.8 mn investment secured to accelerate growth, indicate a robust financial strategy aimed at expanding their manufacturing capabilities and market reach.

The company plans to use the September 2026 funding to support market expansion and expand adoption across industrial sectors.
