Sweden's SweGaN Raised 12 Million Euros for a European Power Chip

SweGaN, a Linkoping wafer maker that already supplies Ericsson and Saab, closed a 14 million dollar Series B on August 17, taking its total funding to 41 million dollars. The bet is on a European source for the gallium nitride wafers that power EV chargers, 5G base stations and data-center supplies.

Sweden's SweGaN Raised 12 Million Euros for a European Power Chip

Key takeaways

SweGaN AB, based in Linkoping, Sweden, closed a Series B of 14 million dollars, 12.09 million euros, on August 17, 2026, taking its total funding to 41 million dollars, according to the company's own announcement.
The round was led by Thisbe AB, part of the Wallenberg investment ecosystem, and North Ventures of Copenhagen, with participation from existing shareholders. SweGaN's own CFO, Stefan Axelsson, described it as an up-round, meaning the company raised at a higher valuation than its previous round, though the exact figure was not disclosed.
SweGaN makes gallium nitride on silicon carbide, GaN-on-SiC, epitaxial wafers, the material that goes into power amplifiers and power electronics for 5G and 6G base stations, EV fast chargers, and increasingly the power-conversion hardware inside data centers.
The company already counts Ericsson, Saab and Chalmers University of Technology among its customers for 6G power-amplifier work, according to SweGaN and independent industry press, meaning this raise funds expansion of an already-selling business rather than a first product.
For a European buyer sourcing power electronics, the relevant fact is not the round size but the geography: most GaN wafer supply today runs through a small number of Asian and US producers, and a funded, customer-validated European alternative changes who a procurement team can call when it wants a second source.

A Small Round, an Existing Customer List

SweGaN announced on August 17 that it had closed a Series B round of 14 million dollars, 12.09 million euros, led by Thisbe AB and North Ventures, with existing shareholders also participating. That brings the Linkoping-based company's total funding to 41 million dollars since founding. SweGaN's own CFO, Stefan Axelsson, called it an up-round, the company's language for a raise priced above its previous valuation, though neither SweGaN nor its investors disclosed the actual number.

What separates this raise from a typical early-stage semiconductor round is that SweGaN is not funding a first product. The company already sells gallium nitride on silicon carbide epitaxial wafers to customers that include Ericsson, Saab and Chalmers University of Technology, largely for power-amplifier work tied to 6G research. This is expansion capital for a business with paying customers, not seed money for a lab result.

Why a Wafer Material Matters Beyond the Lab

Gallium nitride on silicon carbide is not a consumer-facing product, but it sits underneath several things a European operator does care about. GaN-based power electronics run more efficiently at higher frequencies than the silicon they replace, which is why they show up in EV fast chargers, 5G and 6G base station power amplifiers, and increasingly in the power-conversion stages of data centers, where every efficiency point matters as AI compute pushes electricity demand higher.

That last use case is the one worth watching. As data-center operators and utilities across Europe grapple with rising power demand from AI workloads, the components that convert and manage that power efficiently are not a side detail, they are part of the cost and capacity equation. A wafer supplier feeding that chain is adjacent to a story this outlet has covered repeatedly this year: European grid capacity and data-center power are becoming a genuine constraint on how fast AI infrastructure can be built.

The Procurement Argument, Not the Venture One

For most readers, a 12 million euro Series B in a Swedish deep-tech company is not itself the story. The reason it belongs on a procurement radar is geography: GaN wafer manufacturing today concentrates among a small number of producers based in Asia and the United States. A funded, revenue-generating European alternative does not replace that supply chain, but it gives a hardware, telecom or data-center buyer doing supplier diversification a second name to call, backed by customers that already include a major European telecom equipment maker and a defense contractor.

That is the practical takeaway for a European hardware or infrastructure team: this is not a company to invest in from this article, it is a supplier worth adding to a sourcing shortlist the next time a GaN-based component contract comes up for renewal, particularly for teams already thinking about supply-chain concentration risk under the EU's broader chip-sovereignty push.

Frequently asked questions

How much did SweGaN raise, and who led the round?

SweGaN closed a Series B of 14 million dollars, 12.09 million euros, announced August 17, 2026. The round was led by Thisbe AB, part of the Wallenberg investment ecosystem, and North Ventures of Copenhagen, with participation from existing shareholders. Total funding since founding now stands at 41 million dollars, according to the company.

What does SweGaN actually make?

SweGaN produces gallium nitride on silicon carbide, GaN-on-SiC, epitaxial wafers, a material used in power amplifiers and power electronics for applications including 5G and 6G base stations, EV fast chargers, and power-conversion hardware in data centers.

Why would a European business care about a Swedish wafer supplier's funding round?

Because most GaN wafer supply currently runs through a small number of Asian and US producers. A funded, customer-validated European alternative, one that already supplies Ericsson, Saab and Chalmers University of Technology, gives European hardware and infrastructure buyers a second source to consider for supply-chain diversification, independent of any decision to invest in the company itself.

The round is small. The supply chain it sits in is not. Add SweGaN to the shortlist the next time a GaN-based power component contract comes up, not because of the funding, but because of who is already buying from it.
