About Optima

Experienced, passionate payments professionals.

Optima is a Manchester-based specialist payments consultancy founded in 2007. We work with the organisations that move money: tier-one issuers, challenger banks, fintechs, card schemes and lenders. Payments is the only thing we do. That is why clients bring us the problems that sit too deep in the detail for a generalist firm to reach.
