Who was Mike Lynch, the tech entrepreneur who died in Bayesian yacht sinking?

The Autonomy founder, who beat the odds in a 13-year legal battle, has died after his yacht sank off the coast of Sicily

Just weeks ago, Mike Lynch was walking out of a San Francisco court room a free man with tears in his eyes.
The technology tycoon known as “Britain’s Bill Gates” had beaten the odds in a bitter US legal dispute with technology giant HP, convincing a jury that he was not guilty of claims of massive fraud.
Cleared after a 13-year legal fight, the entrepreneur vowed to fight to reform Britain’s extradition laws after he was flown to San Francisco to face trial and kept under house arrest.
Yet tragedy has now struck the 59-year-old so soon after his victory. Mr Lynch has been confirmed dead after his yacht sank off the coast of Sicily in the early hours of Monday morning, while his daughter Hannah remains missing.
The 56-metre Bayesian sank to the seabed off the coast of Palermo after locals reported a freak tornado.
Angela Bacares, Mr Lynch’s wife, was also on board and was among the 15 passengers rescued.
Mr Lynch was one of Britain’s best-known and most controversial technology entrepreneurs.
Born to an Irish immigrant family and raised in London in the 1960s, Mr Lynch had a modest upbringing but won a scholarship to the private Bancroft’s School aged 11.
He went on to graduate from Cambridge University and subsequently founded the business that would make his name: Autonomy. The software company, set up in 1996, used complex statistical analysis to help businesses manage their data.
Autonomy grew rapidly and joined the ranks of Britain’s blue chips on the FTSE 100 before being sold to HP for more than £8bn in 2011.
Mr Lynch used his wealth to become a founding investor in Darktrace, the FTSE 100 cyber security company, and set up venture capital firm Invoke Capital to back other start-ups. His successes once led him to be lauded as “Britain’s Bill Gates”.
For 13 years, however, Mr Lynch was dogged by claims that his success was built on the back of fraud. HP wrote off much of the value of Autonomy shortly after acquiring the business and accused Mr Lynch of exaggerating the business’s success to get HP to overpay.
In 2022, Mr Lynch lost a $5bn (£3.9bn) fraud civil dispute against HP in the British High Court over the sale and was later charged with multiple counts of criminal fraud by the US government for his alleged role.
Last year, he was extradited from Britain to stand trial before a California court. He faced up to 25 years in prison.
In the run up to the trial, the entrepreneur spent months under house arrest with constant monitoring by an armed security detail. Mr Lynch was forced to wear a GPS tag and subject to a $100m bail bond.
Few observers gave Mr Lynch much hope of beating the charges, given the high conviction rate in such cases. The US government had spent years and large amounts of money to prove Mr Lynch had masterminded a scheme to artificially inflate the revenues of Autonomy.
But on June 7, after an 11-and-a-half-week trial, Mr Lynch was acquitted and walked from court a free man – a remarkable moment of vindication for the technologist who had always denied wrongdoing.
In a last-minute gambit, Mr Lynch had taken to the witness stand to defend his record, denying he had been the “driving force” behind the complex fraud. He told the jury that while he had been in charge of the technological vision, he was not involved in the minutiae of the company’s accounting.
The high-risk defence paid off and Mr Lynch was acquitted by the jury after three days of deliberation. Moments after he was declared “not guilty” to each of the 15 charges, his wife rushed over to embrace him.
“I am elated with today’s verdict and grateful to the jury for their attention to the facts over the last 10 weeks,” Mr Lynch said at the time.
“My deepest thanks go to my legal team for their tireless work on my behalf. I am looking forward to returning to the UK and getting back to what I love most: my family and innovating in my field.”
Having returned to the UK, Mr Lynch was preparing to campaign against what he viewed as Britain’s one-sided extradition treaty with the US.
In 2023, he had been escorted from his country home in handcuffs to a waiting plane and spirited across the Atlantic after then-home secretary Priti Patel signed off on his extradition. This was despite the UK’s Serious Fraud Office dropping a case against him years earlier.
“The system can sweep individuals away,” he said in a recent interview.
Mr Lynch owned a home in west London but lived primarily at a farm in Suffolk, where he raised rare breeds of pigs and cows.
In recent years he had suffered from health issues including a lung condition.
Last month he told a newspaper in his first interview since being found not guilty: “Now you have a second life. The question is, what do you want to do with it?”
Over the weekend, Mr Lynch was aboard his personal yacht off the coast of Sicily. The boat, Bayesian, was named for the branch of statistics which was the subject of Mr Lynch’s Cambridge PhD.
Built in 2008, the 56-metre, 473-tonne superyacht is reported to have had capacity for 12 guests and 10 crew members with a top speed of 12 knots. Its listed owner is Ms Bacares, Mr Lynch’s wife.
On board with the couple were Charlotte Golunski, a partner at Invoke Capital, and her husband, James Emsley. Others on the vessel were business associates and legal advisers to Mr Lynch as well as the ship’s crew.
They included Jonathan Bloomer, the former chairman of Morgan Stanley International, and Chris Morvillo, a legal adviser to Mr Lynch and a partner at Clifford Chance.
Ms Golunski, who was rescued from the vessel with her husband and baby daughter, told Italy’s Corriere Della Sera newspaper they were “all guests of our boss” who she described as an “extraordinary person”.
The vessel was reported to have travelled from Aeolian Islands to Milazzo and Cefalù before arriving at Palermo.
There it was reportedly hit by a freak storm, described by local fisherman as a tornado. Fifteen passengers were reportedly rescued by Italy’s coast guard helicopters.
A local fisherman told Corriere Della Sera: “At about 3:55 we saw the whirlwind. A quarter of an hour later we saw a rocket 500 metres from the dock. At about 4:35 we went out to sea to provide assistance, but we only saw the remains of the vessel floating.
“There were no men in the sea. So we immediately called the port authority.”
Mr Lynch and Ms Bacares had two daughters, aged 18 and 21, students at Oxford and Imperial College London respectively. The couple’s daughter Hannah, who was on board the superyacht when it sank, is still missing and feared dead.
Mr Lynch’s personal net worth was estimated at $450m by his US lawyers last year, although a lot of the couple’s wealth is held by Ms Bacares.
A private couple, public records suggest Ms Bacares, 57, and Mr Lynch married in 2001 in London. 
The millionaire’s wife stood by Mr Lynch throughout his legal trials, attending every day of his US criminal court battle in San Francisco.
To keep Mr Lynch company during his house arrest, Ms Bacares bought her husband a sheep dog named Faucet.
Having survived the disaster on the Bayesian, Ms Bacares was reportedly using a wheelchair after sustaining cuts to her feet during the escape.
