Finnish laser maker Vexlum secures €10M in largest Nordic photonics seed round

What's the deal? Vexlum, a Tampere-based manufacturer of semiconductor lasers, has raised €10 million to scale its chip manufacturing and laser technology operations in Finland. The round includes €6 million in equity led by KvantedDealroom has a profile for this one. Try Dealroom →, with participation from Finnish state-owned Tesi and the EIC Fund, plus a €2.4 million grant from the EIC Accelerator and a €1.6 million loan from NordeaDealroom has a profile for this one. Try Dealroom →. The company claims this is the largest seed round to date for a photonics company from the Nordics.​

Vexlum specialises in high-power semiconductor laser systems based on its proprietary Vertical-External-Cavity Surface-Emitting Laser (VECSEL) technology. The company supplies lasers for trapped-ion quantum computers, satellite optical communications, next-generation optical atomic clocks, and semiconductor metrology.​

Why now? The funding addresses a critical bottleneck in high-tech industries: the lack of compact, cost-effective, high-power laser sources at precise wavelengths. Quantum computers, atomic clocks, semiconductor metrology, and free-space optical communication technology all depend heavily on lasers. Vexlum is moving beyond boutique production to industrial-scale capability, expanding its manufacturing capacity to meet demand from quantum, semiconductor, and space sectors.​

The company will use the capital to bring semiconductor manufacturing into a new, expanded facility in Tampere. Its chip fabrication process uses molecular beam epitaxy, where semiconductor wafers are "grown" in a reactor layer by layer at the atomic scale using III-V semiconductor materials such as gallium arsenide, indium phosphide, and gallium antimonide.​

The signal: This investment highlights Tampere's emergence as a leading hub for optoelectronics and III-V semiconductor technology. The round signals growing investor confidence in deep tech companies that can bridge the gap between laboratory precision and industrial scale. Vexlum targets €100 million in revenue by 2030, betting that the rigorous architecture developed for quantum computers will drive the next generation of industrial innovation across multiple sectors.​

The company's vertical integration strategy — controlling the entire value chain from chip manufacturing to final laser systems — positions it to address diverse customer needs across emerging high-tech applications.​
