Tech boss Neil Muller died from a single stab wound to the chest, an inquest has heard.
Mr Muller was 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.
The 54-year-old was found with fatal injuries in a downstairs bathroom at his home in Claverdon, in Warwickshire, on June 7th.
More details emerged at the opening of his inquest at Coventry Coroner’s Court, on Friday.
The four-minute hearing, which was overseen by coroner Sean McGovern, heard that Mr Muller was found with a single stab wound to the chest and suffered a cardiac arrest.
The inquest was adjourned to a date to be fixed pending further investigations.
At the time of his death, a spokesperson for Warwickshire Police, said: “We have launched an investigation following the death of a man at a house on Langley Road in Claverdon on Sunday morning.
“We received a report from ambulance services at 6.15am about a man in his 50s who required emergency medical care following a stab wound to his chest.
“Sadly, he was declared deceased at the scene at 6.37am.
“At 7.33am, a 55-year-old woman from Birmingham was arrested on suspicion of murder. She has since been released on bail. An investigation is underway.”
Prior to joining Node4, Mr Muller was served as CEO of Digital Space for seven years between 2018 and 2025.
Before that, he was group CEO of Daisy Group from 2015-2018 after spending more than 20 years at Computacenter.
