Dojo (Paymentsense Limited) is a UK payment provider building card acquiring, transaction processing, EPOS integrations and consumer apps for in-person commerce.
Paymentsense Limited trades as Dojo, a UK payment provider founded in 2009 that builds card acquiring, transaction processing and EPOS integration technology for in-person commerce. The threat model here is the obvious one and the hard one: the company processes millions of card transactions weekly for over 140,000 customers, spanning hospitality bookings and a consumer restaurant app alongside the core acquiring stack. Payment data, transaction integrity and merchant-facing integrations are the assets in play, and they sit inside systems that cannot go down during trading hours.
The technical surface is broad rather than exotic. Domains include payments technology, fintech, EPOS integrations, card payment acquiring, transaction processing and mobile app development, with products ranging from sophisticated point-of-sale payment integrations to fast in-person card transactions, a hospitality bookings product and a consumer-facing restaurant app. Dojo operates from seven international offices - London, Bristol, Hull, Dublin, Madrid, Barcelona and Milan - serving customers across the United Kingdom, Ireland, Spain, Italy and France, so security work spans multiple jurisdictions and partner integrations rather than a single perimeter.
The company employs over 1,200 people and reports more than 15 years in payments, describing itself as the largest card payment acquirer in the UK and one of Europe's fastest-growing fintech companies. Its stated framing is a thriving in-person economy powered by tech and enabled by people - which, in practice, means security and engineering sit close to a business whose product is the reliability of the transaction itself.
