One of the largest banking groups in the Nordics was losing market share in small business banking. We partnered with the bank to redesign its commercial operating model end-to-end, from acquisition to retention. Within 18 months, the bank moved from negative growth to gaining more than 700 net new customers per month.

Outcome 1: Gained 700+ net new customers per month from Q4 2025 after reversing customer and market share decline

Outcome 2: Reduced customer onboarding time from 30+ days to as little as 2 days

Outcome 3: Increased website conversion to new customer applications by 40%+

The challenge

The Nordic small business banking market has become increasingly competitive, with digital-first challengers reshaping customer expectations around speed, simplicity and pricing. At the same time, regulatory requirements and growing operational complexity have made it harder for incumbent banks to respond quickly.

Our client had been steadily losing market share in the SMB segment. To reverse this trend, the bank set an ambitious goal: return to sustainable growth and regain market share within five years. Achieving this required a fundamental redesign of its commercial operating model.

A commercial maturity assessment identified structural weaknesses across acquisition, onboarding, retention and the use of customer data. Advisors spent much of their time on administrative and compliance activities, leaving limited capacity for proactive sales.

Customer portfolios lacked clear segmentation, value propositions were inconsistent and growth depended more on individual effort than systematic, data-driven execution. Lengthy, resource-intensive onboarding processes further constrained growth. The challenge was to improve productivity and accelerate customer acquisition without increasing frontline headcount or compromising risk and compliance.

The approach

Working closely with the executive team and commercial leaders, we designed a new operating model tailored to the SMB segment.

The transformation spanned the entire customer journey, from acquisition and onboarding through to retention and cross-sell. We introduced a new customer segmentation model, significantly expanded digital marketing and paid media, and repositioned the website as a high-performing digital sales channel. Onboarding was redesigned end-to-end through a combination of new technology and streamlined processes, while data-driven activation programmes and four coordinated transformation workstreams ensured consistent execution across markets.

The impact

The results were both rapid and tangible.

The bank moved from losing customers to acquiring more than 700 net new customers per month by Q4 2025. Onboarding times fell from more than 30 days to as little as two days in implemented markets, releasing significant operational capacity while maintaining compliance standards. Website conversion to new customer applications increased by more than 40%.

More broadly, the transformation replaced a fragmented, advisor-led approach with a scalable, data-driven commercial engine capable of delivering sustained growth and long-term market share gains.
