About Marginum
Marginum is a Kuopio-based medical device company that develops the HIVEN Aspirate Tissue Detector for fluorescence-guided surgery. The device analyses fluorescence in tissue within surgical suction fluid during operations for suspected high-grade gliomas where 5-aminolevulinic acid is used, and gives neurosurgeons audio feedback. HIVEN is classified as risk Class IIb under EU MDR, and the company's quality management system is certified to ISO 13485:2016.
Its customers are neurosurgeons and healthcare institutions that perform oncological surgery. The device is sold through distribution partners, including ALMEDA in the Czech Republic and Slovakia, ABS Med for the U.S. Midwest (subject to FDA authorisation), and distributors in the Nordics, Iberia and Southeastern Europe.
Marginum was founded in 2020 and is headquartered in Kuopio, Finland. Its timeline lists EU market entry and MDR certification in 2025, a U.S. clinical study started at the University of Illinois Hospital & Clinics in Chicago in 2026, and a Red Dot Product Design Award for HIVEN in 2026. The company reports seed funding in 2023 and pre-Series A funding in 2025.
