Appointments

Node4 has appointed a new chief executive following the sudden death of Neil Muller.

Mr Muller, who was group CEO of Derby-based Node4, was found fatally stabbed at his home in Claverdon, Warwickshire, on June 7.

An inquest into his death at Coventry Coroner’s Court heard that the 54-year-old was found with a single stab wound to the chest and suffered a cardiac arrest.

His family launched a JustGiving appeal for men’s suicide prevention charity ANDYSMANCLUB. The Mul Memorial Fund has raised £8,615.

New CEO Serge Lupas immediately paid tribute to his predecessor.

Mr Lupas said: “What drew me to Node4 was the strength of the people, the quality of customer relationships and the depth of capability across the business.

“While I didn’t know Neil Muller personally, I’ve heard a great deal about the energy, ambition and belief he brought to Node4. I have real confidence in the strategy and the direction that has been set.

“My immediate focus is to listen, learn and work alongside colleagues and customers and help accelerate the momentum already underway.”

Patrick De Smedt, non-executive chair, added: “Neil Muller led Node4 with enormous energy and conviction, and he is deeply missed.

“In Serge, we have found an experienced leader who recognises the strength of the strategy Neil helped shape with the board and executive team and has the capability to accelerate its delivery for our customers and our people.

“Our strategic direction remains unchanged. Serge joins us to build on the strong foundations already in place and lead Node4 through its next phase of growth.”

Prior to joining Node4, Mr Muller served as CEO of Digital Space for seven years, between 2018 and 2025.

Before that, he was group CEO of Daisy Group from 2015 to 2018 after spending more than 20 years at Computacenter.
