Unit4 appoints Stuart Nash as Chief Operating Officer
Thu, 6th Aug 2026 (Today)
Unit4 has appointed Stuart Nash as Chief Operating Officer, bringing Customer Success and IT operations under his leadership.
Nash joins from Finastra, where he was Senior Vice President and Global Chief Information Officer. In the new role, he will oversee Customer Success, including the Success4U programme, alongside Unit4's IT operations team.
The appointment also marks a leadership departure. Jean de Villiers, Chief Customer Officer, is leaving after helping establish the company's Customer Success strategy and positioning Success4U as its main customer engagement model.
Nash's remit includes building on the current Customer Success set-up and working with the IT team on broader integration and optimisation of end-to-end business processes. Unit4 also said customers are now completing implementations in an average of 90 days.
He brings experience across customer operations, technology and business transformation. At Finastra, he led a business responsible for USD $250 million in revenue, according to Unit4, while overseeing changes aimed at improving employee and customer experience.
Earlier in his career, Nash held senior roles at NHS Test & Trace and Vodafone UK. At Vodafone, he spent more than 14 years leading customer and technology operations, as well as business-wide transformation programmes.
Leadership change
The move gives Nash responsibility for two functions closely tied to customer delivery and internal systems. For Unit4, it signals an effort to place service delivery, customer adoption and internal operational change under one executive.
Simon Paris, Chief Executive Officer at Unit4, said: "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.
"Customer Success remains central to how we support our customers and 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."
Operational focus
Nash will work on customer onboarding and adoption, while also focusing on how IT supports the wider business. That includes the relationship between internal systems, service delivery and business processes across the company.
Unit4, which sells cloud-based business software, has increasingly emphasised Customer Success as a way to support migrations and implementations. Bringing that organisation together with IT operations under one executive suggests it wants tighter coordination between customer-facing work and internal execution.
That may be particularly relevant as software groups try to cut deployment times and improve retention among existing customers. Unit4 said its current model has already shortened implementation periods to 90 days on average.
Nash said: "It is exciting to be joining Unit4 as it implements its 2030 strategy to significantly grow the business.
"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."
