"We are very pleased to have Jeremy on board focusing on further improving our customer experience and ensuring we get our customers the business results they want," said chief executive Stephan Sieber.
"Under Jeremy's lead we will further align product management and product marketing to deliver a premium end-to-end experience for customers and ensure that our product roadmaps and go-to-market offerings fulfil sector and customer needs.
"Jeremy takes over from Ivo Totev who has contributed a great deal to Unit4 over the last three years.
Roche was one of the founders of Unit4 and was active at board level during his previous 'day job' as CEO of cloud ERP vendor FinancialForce, which was part-owned by Unit4. He will continue to serve FinancialForce as founder and special advisor to the management team. The new CEO of FinancialForce is Tod Nielsen, who previously worked for Salesforce.com.
Roche holds a degree in Business Studies from Thames Polytechnic in the UK.
"I relish this new challenge and look forward to putting my experience to good use," he said.
"Unit4 continues to innovate to meet the needs of its customers at a time of rapid cloud adoption and digital transformation. It's an exciting time for the company and for me as we capitalise on the cloud opportunity that exists today."
