## About

Based in Finland, Vexlum specializes in high-performance semiconductor laser technologies designed for applications in quantum technology, medicine, and the semiconductor sector.Founded in 2017 and headquartered in Tampere, Finland, Vexlum focuses on developing advanced semiconductor laser technologies. The company was co-founded by Jussi-Pekka Penttinen and Mircea Guina. Vexlum has completed a total of 3 deals, with the most recent funding round being a Grant of EUR 2.40 mn raised in February 2026 from the European Innovation Council, totaling EUR 6.00 mn raised to date.Vexlum specializes in the development of advanced semiconductor laser technologies tailored for high-impact applications across various sectors, including quantum technology, medicine, and the semiconductor industry. The company’s core products utilize Vertical External Cavity Surface Emitting Lasers (VECSELs), which merge the advantages of semiconductor lasers with those of optically-pumped external-cavity disk lasers to provide high-power, low-noise single-frequency lasers. These products offer broad wavelength coverage extending into both the visible and near-infrared spectrum, making them suitable for diverse applications such as optical communication, medical diagnostics, and industrial laser processing. Vexlum serves a global client base that includes research institutions, medical device manufacturers, and semiconductor companies, delivering its solutions to markets in North America, Europe, and Asia.Vexlum generates revenue through direct B2B transactions with clients, which include academic institutions, research laboratories, and companies within the semiconductor and medical sectors. The company operates on a model where customers purchase laser systems tailored to specific applications, often leading to recurring orders for consumables or service agreements. Pricing structures reflect the advanced technology and customization involved, ensuring that each laser system meets the unique performance needs of its end users.In February 2026, Vexlum raised EUR 6 mn in funding, led by Kvanted Ventures, with additional participation from Tesi and the European Innovation Council. This funding will be utilized to increase production of VECSEL lasers and support the development of new quantum technology applications. The company aims to expand into new markets, particularly targeting additional regions in Europe and Asia by the end of 2026, while launching new products designed to enhance their offerings in high-performance laser technology.
