Brewdog co-founder James Watt has apologised to staff and investors and admitted he made "many mistakes" after hundreds of jobs were lost following the sale of the brewer and pub chain this week.
The company's brewery and 11 bars were bought by US firm Tilray for £33m after it went into administration on Monday - but 38 other pubs closed and 484 staff have been made redundant.
Unions, staff and investors have voiced anger at how the sale of the business was handled.
In a statement posted online, Watt said it had been an "incredibly hard" week and that he was "heartbroken" for those who had lost their jobs and invested in its Equity For Punks scheme.
Watt co-founded the company in Aberdeenshire with Martin Dickie in 2007.
