Institutional Client review:
Sean has been a visionary in the fintech and digital asset space for many years and has found a way to provide innovative solutions for organisations who do not fit the risk appetite of other financial services providers. Sean takes a high profile approach to addressing the issues of digital asset businesses and advocates for better access to banking services for this under represented sector. Add to this his wealth of knowledge and experience in the sector (and others) and his open and honest approach he is a pleasure to work with and has built a likeminded team at Greengage.
