When Mike Lynch, described at one time as Britain’s Bill Gates, passed away last week, it was a shocking turn of events that would have sounded like a plot twist in an HBO show if it hadn’t been starkly real. Lynch was originally among six people listed as missing in the aftermath of an accident that sank a superyacht, named the Bayesian, in the Mediterranean. Lynch’s 18-year old daughter also died in the accident. 

Lynch was only 59, and was just embarking on a new chapter in his life: He had just been acquitted on all charges in a fraud case that played out for more than a decade, and was on the Bayesian with friends, celebrating the turning page. 

Lynch was an unlikely tech founder in an unlikely place, as my colleague Ryan Hogg writes: 

Lynch was born in Ireland and raised in Chelmsford, Essex. His mother was a nurse, and his father was a firefighter. Speaking in 2016, Lynch said his father gave him the advice to “get a job that doesn’t involve running into burning buildings.”

Lynch’s software company Autonomy would prove to be both his making and his albatross. The startup—focused on enterprise and in part built on Bayesian inference methods (hence, the name of the yacht)—grew rapidly after Lynch cofounded it in 1996. Autonomy did a number of high-profile acquisitions through the 2000s, and was acquired by HP in 2011 for more than $11 billion. That’s where things get complicated: HP wrote the investment down by $8.8 billion just a year later, citing “accounting irregularities.” This kicked off a legal battle that would last for years in which HP accused Lynch of fraud, while Lynch consistently denied the charges. Autonomy’s former CFO was found guilty of fraud in the U.S. in 2018. 

But in July, Lynch was acquitted on all 17 charges brought against him. And on the yacht, Lynch was said to be celebrating his new lease on life.

Lynch leaves behind a complex legacy, and some outstanding questions. He, through his VC firm Invoke Capital, was an early key investor in cybersecurity company Darktrace, which Lynch first invested in in 2012. As my colleague Leo Schwartz writes: 

One of its most profitable investments was Darktrace, a cybersecurity firm that shared deep connections with Autonomy, including, as of early 2020, half of Darktrace’s board and six of its eight top executives. Lynch and his wife held a combined stake of around 7% in Darktrace as of April 2024.

In part thanks to its ties to Autonomy, Darktrace soon became mired in scandals, including a Forbes investigation that alleged widespread sexual harassment. Despite the bad press, Darktrace went public in April 2021, with its price soaring from an initial valuation of $2.4 billion by 43% on its first day of trading.

The honeymoon didn’t last. In September 2022, discussions of an acquisition between Thoma Bravo and Darktrace fell through, sending share prices tumbling. And then in early 2023, the short-selling firm Quintessential Capital Management published a 70-page report accusing Darktrace of similar misconduct that had sunk Autonomy. 

Thoma Bravo announced plans to acquire Darktrace in April for $5.3 billion, a deal that’s likely to proceed as planned, as my colleague Luisa Beltran reports: 

The deal still needs regulatory approval, but Thoma Bravo is expected to complete the acquisition by the end of 2024, a person familiar with the transaction said.

“If the shares have already been voted, there is no obvious mechanism or need for further approval or action to be taken by any shareholders, including the Lynch family or estate,” an attorney who advises on M&A transactions told Fortune.

Lynch’s passing may not change the outcome for Darktrace, but it does highlight the harsh reality that even when we get second chances, we never know how long we have to make the most of them.
