Polar Light completes $3.4m funding round
Sweden-based microLED company Polar Light Technologies has closed a fully subscribed funding round of $3.4m, drawing strong interest from both existing and new investors.
All major shareholders participated in the round – including Stoaf SciTech and fam Bo Eklöf, which increased its stake beyond its pro rata share, as well as Almi Invest, Sustainable Energy Angels, Butterfly Ventures, and LiU Invest. J2L Holding has joined as a significant new investor.
With this strengthened backing, the company says it can now enter its commercialisation phase, aiming to bring its patented microLED technology to market in 2026. A larger financing round is planned for 2026 to support full-scale market entry.
Polar's technology enables significantly smaller, more efficient microprojectors and displays. It emits red, green, and blue light from the same material compound—without the compromises or added complexity typically required by competing approaches.
“This is a major milestone for us,” says Oskar Fajerson, CEO of Polar Light Technologies. “We’ve methodically advanced from deep research to a commercially viable solution. Investor interest confirms both their belief in our technology and our ability to deliver. This capital will allow us to accelerate our journey toward product launch in 2026.”
In December 2024, the company achieved a pivotal technical breakthrough: red emission at 625 nm using its bottom-up pyramidal microLED design. With red, green, and blue now all achieved using the same material system, Polar Light Technologies is laying the foundation for truly monolithic RGB displays.
Among the participating investors, Stoaf SciTech took a particularly strong position. “We chose to invest more than our pro rata share because we strongly believe in Polar Light Technologies’ potential to transform the microLED market,” says Klaus Gottwald from Stoaf SciTech. “What the team has achieved—technically and strategically—is rare. This is not just a great technology; it’s a company ready to lead. We’re proud to be part of their journey and to support them in scaling toward commercialisation.”
“The semiconductor sector is buzzing with new players and innovation, and we believe Polar Light Technologies stands out in a very exciting way,” says Johan Lindh from J2L Holding. “MicroLEDs and next-gen display technologies are strategic not just for the industry, but for Europe as a whole—and it’s remarkable to see a Swedish company leading at the frontier.”

Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
