Refeyn is the world's pioneer in mass photometry – a ground-breaking technology that weighs individual molecules and particles with light. It transforms our ability to characterise the composition, structure and dynamics of biomolecules and biomolecular complexes, nanostructures, and viral capsids.

Since being spun out of the University of Oxford in 2018, Refeyn has been developing mass photometry instruments and delivering them to customers around the world – at leading academic institutions and in biopharma. We are continuously pushing the boundaries of what mass photometry can achieve.

With headquarters in Oxford, UK as well as offices in the US, we are a growing, global company with a team of over 170 employees (and growing). In addition to achieving market success, Refeyn has attracted a high level of investment – we raised $70m in our Series B funding round in March 2022.

At Refeyn, we are fiercely proud of our talented workforce, whose creativity, tenacity and skills have enabled us to evolve into a successful, well-funded and rapidly growing company in just a few years. To achieve our ambitions – to transform analytical workflows in the life sciences, biopharma and beyond with mass photometry – we are continuing to expand our workforce.

We strive to be an outstanding place to work – by maintaining a positive and inclusive culture, offering competitive salaries and benefits, encouraging ongoing training and development, plus, of course, plenty of other perks.
