About Refeyn

Refeyn, spun out of Oxford University in 2018, specializes in mass photometry, a groundbreaking technology that allows for the precise mass measurement of single molecules in their native state without the need for labels. This innovative approach opens new possibilities for bioanalytics and the study of biomolecular functions. Refeyn's compact, bench-top instruments require minimal installation and only a few microliters of sample, making them highly accessible to the scientific community. The software automates the acquisition process and performs mass analysis in minutes, enabling researchers to intuitively interpret mass distribution results without prior knowledge. Refeyn serves academic institutions, research laboratories, and pharmaceutical companies, operating in the bioanalytics market. The company's business model revolves around the sale of its mass photometry instruments and related software, generating revenue through direct sales and potentially through service contracts and maintenance agreements.
