A Scottish technology company is taking another major step toward commercialising graphene after raising £22.7 million to expand production of its proprietary material and push it further into the health, energy and life-sciences markets.
Stirling-based iGii, formerly known as Integrated Graphene, secured an £11.7 million Series B investment led by the Scottish National Investment Bank, with participation from PXN Ventures and Archangels. The company also received £11 million from Scottish Enterprise, bringing the total funding package to £22.7 million.
The funding arrives at an important stage for the company. Rather than remaining focused primarily on research and development, iGii is now looking to scale the manufacturing and commercial use of its graphene-based technology.
Making graphene easier to use
Graphene has attracted enormous attention in technology and materials science because of its unusual combination of strength, conductivity and other physical properties. However, one of the challenges facing manufacturers has been turning the extremely thin material into something that can be produced and handled economically at industrial scale.
That is where iGii’s technology comes in.
The company has developed a material called Gii, which is around 40 microns thick. While traditional graphene consists of a single layer of carbon atoms, Gii is designed to retain graphene-like properties while being substantially easier to handle and integrate into commercial products.
According to the company, its manufacturing process allows the material to be produced using a reel-to-reel approach, creating the possibility of much larger-scale production.
That could be particularly important for industries that want to use advanced materials without having to redesign their entire manufacturing processes around an extremely delicate material.
From research to commercial products
iGii currently manufactures electrodes for applications spanning human diagnostics and energy. Its technology is also being explored for use in life-sciences hardware and other industrial applications.
The company has already demonstrated that there is commercial interest in its technology. In 2025, iGii agreed a multimillion-pound deal with Hereford-based health-monitoring company Prymexa to develop technology for detecting perimenopause.
The new funding is intended to help the company move further into commercialisation while continuing research into the properties and possible applications of Gii.
iGii currently employs about 55 people and plans to increase that number to around 70 by the end of 2026. The company says its international workforce represents more than 22 languages, reflecting the global talent behind its Scottish operations.
A bigger opportunity for UK advanced materials
The development also comes at a time when governments and manufacturers are paying greater attention to domestic production of advanced materials.
Global supply chains for important industrial materials remain vulnerable to geopolitical disruptions and concentrated production. Materials that can reduce dependence on expensive or difficult-to-source components could therefore become increasingly important to manufacturers.
Graphene is particularly interesting because of its potential applications across electronics, energy, healthcare and industrial technology.
The UK has historically struggled to turn its graphene research strength into large-scale commercial production. iGii’s strategy is to keep manufacturing in Britain while developing products that can eventually be exported internationally.
For iGii, the immediate priority is no longer simply proving that graphene can work. The bigger challenge is demonstrating that it can be produced consistently, economically and at sufficient scale for real-world industries.
With more than £22 million in new funding behind it, the Stirling company now has additional resources to tackle that challenge.
If successful, iGii could become another example of a British deep-tech company turning advanced materials research into commercially useful technology.
