iGii Raises £11.7M Series B Led by Scottish National Investment Bank

iGii Secures £11.7M in Series B Funding

iGii, a Stirling-based deep-tech advanced materials company, has raised £11.7 million in Series B funding. The round was led by the Scottish National Investment Bank, with participation from Archangels and PXN Ventures.

What iGii Does

iGii develops and manufactures Gii, a proprietary 3D porous pure carbon nanomaterial that is grown in the lab rather than mined. The company was formerly known as Integrated Graphene.

The same material platform underpins several distinct technologies:

• Multi-analyte sensing
• Flexible printed battery electrodes
• Microheater technologies

These technologies address applications spanning human and veterinary diagnostics, environmental monitoring, IoT devices and industrial manufacturing.

iGii partners with global manufacturers to turn its material science into differentiated next-generation products.

The Round at a Glance

• Company: iGii
• Round type: Series B
• Amount raised: £11.7 million
• Lead investor: Scottish National Investment Bank
• Additional investors: Archangels, PXN Ventures
• Funding date: September 15, 2026
• Headquarters: Stirling

Why It Matters

The Series B marks a significant step for a deep-tech materials business built on a proprietary platform rather than a single product. Because Gii supports sensing, battery electrodes and microheaters from one material foundation, iGii's commercial reach extends across diagnostics, environmental monitoring, connected devices and industrial manufacturing.

For acquirers and strategic partners, the appeal of a platform like Gii lies in its breadth. A single validated material can be licensed or integrated into multiple product categories, creating several potential paths to revenue and multiple points of technical differentiation. iGii's stated model of partnering with global manufacturers reinforces this, positioning the company as a supplier of enabling technology rather than a single end-product vendor.

The involvement of the Scottish National Investment Bank as lead investor, alongside Archangels and PXN Ventures, provides backing from both institutional and venture sources.

What to Watch

With Series B capital in place, the key questions for observers and potential acquirers will center on commercialization milestones: how quickly Gii-based sensing, battery electrode and microheater technologies move from development into manufacturing partnerships, and which application areas gain traction first. The breadth of the platform is an asset, but execution across multiple verticals will determine how the company scales.

For now, iGii enters its next phase with £11.7 million in new funding and a clear mandate to convert its lab-grown carbon nanomaterial into differentiated products alongside global manufacturing partners.
