James Watt and Martin Dickie launched the craft brewery and bar chain in Aberdeenshire, Scotland in 2007.
Watt tweeted on Sunday (29 March): “In order to protect as many jobs @brewdog as we can, many of our senior team have volunteered to take pay cuts.
“And, myself & my co-founder Martin are forgoing all salary for 2020.
“But, we have not started sleeping in the brewery (yet).”
He added that BrewDog’s chief operating officer Dave McDowall had also volunteered to take a 50% pay cut.
In 2018 the Sunday Times Rich List put the fortunes of Watt and Dickie at £262m and £228m respectively.
The company operates around 100 craft beer bars worldwide.
