The number of company directors under 30 has smashed through the 300,000 mark for the first time ever.
There are 311,550 directors of UK firms aged 29 or under, mid-tier accountancy firm Moore Stephens said.
Millennials and improvements in technology were cited as two reasons for growing numbers of younger directors.
“Highly intelligent and motivated graduates faced an incredibly tough time finding a job in the years following the recession in 2008," said Moores Stephens partner Mark Ayres.
“Many decided to take matters into their own hands and start their own companies – often ‘challenging’ and ‘disrupting’ the status quo.
He continued: “Of course, a major contributing factor to this has been the rise of machine learning, artificial intelligence and blockchain technologies.
“Technology gives entrepreneurs – no matter who they are or where they come from – instant access to millions of potential customers across the globe.”
