Unit4 Hires Stuart Nash as Chief Operating Officer

Customer Success and IT Operations to align under Nash’s leadership 

London, UK, 6th August 2026 – Unit4, a leader in enterprise cloud applications for people-centric organisations, today announced that Stuart Nash is joining the company as Chief Operating Officer (COO). He will assume responsibility for Customer Success, including the Success4U programme, and Unit4’s IT operations team. Stuart joins the company from Finastra where he was Senior Vice President and Global Chief Information Officer and brings a wealth of experience from a variety of executive customer, IT and transformational leadership roles.

Unit4 has appointed Stuart as COO to build on the significant achievements of the Customer Success organisation, which has established a highly efficient and effective model for delivering services to customers. He will be responsible for building on the accelerated onboarding and adoption cycles for customers, who now experience implementations in just 90 days on average. He will also work closely with the IT team to enhance its role as a digital enablement partner for the business, as well as focusing on the broader integration and optimisation of Unit4’s end-to-end business processes.

“Stuart brings 30 years of experience in operational leadership and transformation which will be invaluable in helping us raise the bar for our customers as we continue to innovate,” said Simon Paris, CEO, Unit4. “Customer Success remains central to how we support our customers, helps us deliver the highest levels of satisfaction and retention. Stuart’s brief is to build on the excellent work of the Success4U programme, which is accelerating customer migrations and delivering tangible and rapid time-to-value for our customers.”

As part of the transition, Jean de Villiers, Chief Customer Officer, will be leaving Unit4 having laid the foundations of the Customer Success strategy and established Success4U as Unit4’s primary customer engagement approach. Stuart brings significant experience from Finastra, where he led a business responsible for $250m in revenue while driving improvements in both colleague and customer experiences. Prior to Finastra, Stuart held several senior leadership roles, including with NHS Test & Trace and Vodafone UK, where he spent more than 14 years leading customer and technology operations and business wide transformation programmes.

“It is exciting to be joining Unit4 as it implements its 2030 strategy to significantly grow the business,” added Stuart Nash, COO, Unit4. “Our Customer Success strategy will be integral to bringing our customers on the journey with Unit4 to maximise the value they receive from our AI-native ERP capabilities. Likewise, we must continue to drive innovation and operational transformation in our approach to IT and business processes to best support our teams as they look to deliver value to our customers.”
