From the heart of the City of London to the forefront of digital payments — a legacy of trust, innovation, and unwavering commitment to our clients.
In 1904, Mossen & Co. was established in the City of London, providing bill clearing and remittance services to merchants across the United Kingdom. For over a century, we have stood at the heart of British commerce, adapting and evolving with each generation of financial innovation.
From handwritten ledgers to electronic funds transfer, from the first online payment gateways to today's intelligent orchestration platform — Mossen has continuously pioneered new ways to move money safely and efficiently.
Today, as an FCA-authorised Payment Institution, we combine the wisdom of experience with cutting-edge technology. Our platform processes over £8 billion annually for 2,000+ businesses across 50+ countries. Yet our founding principle remains unchanged: your money is safe with us.
Six generations of payment technology, one constant: trust.
