Our Story

The go-to payments advisors for leading retailers around the globe.

CMSPI is the advisory firm that finance, payments and fraud teams turn to when they want to boost performance, navigate the market, and grow their businesses. Our payments experts use proprietary technologies to equip clients with data-driven insights to achieve best-in-market results through more legitimate transactions, with less fraud, all at a market leading cost.

Our Story

In 2011, after a career advising banks and merchants on improving payments, Brendan Doyle, Founder & CEO, set out to build a business that would change the global retail payments landscape for the better. The result is CMSPI; using a unique combination of knowledge, data and technology to improve the productivity of payments. This means a better outcome for merchants, payments companies and, ultimately, consumers.

Since then, CMSPI has become the go-to advisory firm for leading merchants across the globe, looking to supercharge their payments arrangements. In 2021, Inflexion, a global private equity firm, invested in our vision, helping to fuel our growth and develop new technologies that will drive future improvements in payments productivity.
