The leading consultancy for ecosystem advisory and core transformations

We engaged Quantum Six to support BACB with an ISO20022 market assessment. The work was thorough and went beyond our expectations – and was even delivered in under the estimated days provided. I now consider Quantum Six as a Trusted Advisor.

We were impressed with Quantum Six’s depth of expertise, as well as the practical, results-driven approach that they took. We’d seen similar vendor selection programmes take at least 18-36 months elsewhere, whereas Quantum Six provided independent assurance and led a focussed vendor evaluation process that delivered a combined RFI and RFP in just 3.5 months – as well as supporting with detailed due diligence and risk assessments to enable us to confidently select our vendor. We really value their structured thinking, and collaborative style. This, along with their independence as a business, made them a trusted partner throughout the whole selection process.

Quantum Six delivered a clear, independent assessment of our products and market position, combining competitive analysis with direct customer insights to highlight where we could strengthen and differentiate. Their work helped us refine our customer value proposition and translate our strategy into a focused go-to-market plan that identified the right segments and approach. Throughout the engagement, they acted as a trusted advisor, offering honest, expert guidance grounded in deep knowledge of the UK banking and building society market.
