Inspiring. Unique CEO. Brightest spark. Great guy. Natural born leader.
These are just some of the descriptions of Neil Muller, the 54-year-old tech boss who died on Sunday after being found with stab wounds at his home.
As reported by BusinessCloud yesterday, he was only appointed group CEO of Derby-based Node4 in April 2026, having previously served as CEO of Digital Space for seven years between 2018 and 2025.
Prior to that, he was group CEO of Daisy Group from 2015 to 2018 after spending more than 20 years at Computacenter.
Warwickshire Police are currently investigating his death but have confirmed that a 55-year-old woman from Birmingham was arrested on suspicion of murder and has since been released on bail.
A spokesperson for Node4 said they remain ‘absolutely devastated’ by his death and are supporting each other through the tragedy.
“Neil was a much-valued colleague and a genuinely inspiring leader,” they said in a statement.
“Our thoughts are with everyone who knew him, especially his colleagues, family, friends and loved ones, at this incredibly difficult time.
“Neil has made a real and lasting impression at Node4. He brought energy, drive and a genuine passion for what we are building together.
“Neil cared deeply about Node4 and its people and had invested his time to speak to every colleague in the business, creating a sense of momentum, belief and connection in all of us.
“As a team, we’re supporting each other through this, united by Neil’s vision and the direction he set.”
Brie Birds, a senior account manager at Node4, said: “Neil was inspirational and made a huge impact on a lot of people in such a short period of time.
“His strategy for our business was delivered personally to every member of staff and therefore still stands strong. We are all now responsible for bringing it to life. My thoughts are with his family, friends, and everyone who had the privilege of knowing him.”

Thomas Bevan, AI strategy and innovation director at Node4, said: “Having only worked with Neil for a few short months, I’ve been blown away by his energy, enthusiasm and single-minded focus on the plan, his plan.
“The impact he’s had in the last few months cannot be understated and is a testament to the vision and commitment he had. What a man. What an incredible loss to our business and industry as a whole.”
Clay Van Doren, CEO of Avenga, said: “Deeply saddened by the unexpected passing of a close friend and work colleague, Neil Muller.
“We have lost one of the brightest sparks I’ve known. Neil lit up every room he walked into, and everyone felt moved by his presence and grace. My thoughts are with Neil’s family. I’ll miss him more than I can say.”
Former colleague Karen Yeadon wrote on LinkedIn: “When I first saw the news, I hoped it wasn’t the Neil Muller I worked with at Computacenter, who played such an important role in shaping my career.
“Neil had a wonderful personality, a great sense of humour, and a way of connecting with people that made him a pleasure to work with. I will always remember his positivity, encouragement, and the support he gave to those around him.”
Disbelief
Craig Routledge of Lenovo said: “When I saw the first reports about the death of Neil Muller, I hoped that it wasn’t the Neil Muller who I had helped hire, develop, coach and promote through his early career years at Computacenter.
“Sadly, it was the Neil that I knew. Very sad news. My thoughts go out to his family and friends. He was a great guy to be around.”
Gary Sales, who previously worked at Dell Technologies, said: “This is mental news. Condolences to Neil’s family at this very sad time. A football-loving family man and also a natural born leader.”
Experienced executive Declan Sharpe said: “Such terribly sad news. Neil was so highly regarded by so many. He will be badly missed.”
Gareth Grey wrote : “I’ve worked in many settings over 12 years, from the public sector to small outfits, and Neil was the most unique CEO I had ever met. in the most positive way.
“No other CEOs that I know of would have taken time to make sure he met every employee face-to-face or took any questions encouraging people to ask away. I respected him immensely from only meeting once. and would have followed him anywhere.”
