iGii has secured £22.7 million (about US$30.4 million) in new funding to accelerate the commercialization and industrial adoption of its patented 3D graphene foam, Gii. The round comprises an £11.7 million (about US$15.7 million) Series B investment led by the Scottish National Investment Bank, with additional backing from PXN Ventures and Archangels, plus £11 million (about US$14.7 million) from Scottish Enterprise. This follows an earlier £8.8 million raise in 2024, also led by SNIB, which funded scaling of Gii-Sens, the company's diagnostic-sensor component.
Gii is a patented, porous 3D graphene foam that iGii says can be produced directly onto any surface at room temperature in seconds, a manufacturing approach designed to avoid the scale-up challenges that have historically limited graphene's use in mass-market applications. The company said the new funding marks a shift from years of R&D into commercial execution, and will support continued growth across its team, which is set to climb from 55 to 70 employees by the end of the year.
"Every industrial revolution has been enabled by a breakthrough in materials, and this funding means iGii can help enable the next one," said Jean-Christophe Granier, CEO of iGii. "We've spent years proving what Gii can do and building the manufacturing capability to take it from scientific breakthrough to industrial reality."
