Staff wrote the warning in 2021. Nobody treated it like one.
BrewDog was once the loudest success story in British business. It was said to be worth more than $1bn and owned about 100 bars around the world.
In March 2026, the original company went into administration and its best parts sold for £33 million. Hundreds of people lost their jobs on a short conference call.
Five years earlier, more than 100 former staff had put their names to an open letter describing a culture of fear.
The 2026 statistic every founder should read
The CIPD Good Work Index 2026, published in July and based on more than 5,000 UK employees, found that a quarter of workers have experienced conflict at work. Most of them (51%) just let it go.
One in five employees say they have no way to express their views at work at all. And unhappiness with senior management is one of the top three reasons people change jobs.
Put simply: when things go wrong, most people don’t complain. They go quiet, and then they go.
Why this happens, and when
It happens fastest in founder-led businesses that grow quickly. The founder’s energy builds the brand. The same energy, without checks, can make disagreement feel pointless or unsafe.
It usually starts when growth is the only thing anyone measures. Pressure goes up, people burn out, and the ones who could warn leadership decide it isn’t worth it. By the time the warning goes public, it’s already a reputation problem.
What happened at BrewDog
Here is what has been publicly reported, with sources.
In 2021, more than 100 former employees signed an open letter under the name Punks With Purpose, accusing leadership of fostering a culture of fear driven by relentless pressure and burnout (The Tab, March 2026; BBC).
The company went on to report a £62.7m loss in 2023 and a £34.1m loss in 2024, then closed its distillery in Port Ellen (The Drinks Business, September 2026).
On 2 March 2026, the original company entered administration. Tilray Brands bought selected assets, including the brand, UK brewing operations and a group of bars, for £33 million. Unions criticised the way staff learned about job losses, on a 15-minute conference call with 25 minutes’ notice (BBC).
Administrators have reported that £489,000 owed in wages and holiday pay won’t be paid through the administration. Affected employees will receive compensation through the Insolvency Service instead (The Drinks Business, September 2026).
BrewDog’s response
Co-founder James Watt, who stepped down as CEO in 2024, said on LinkedIn that he made many mistakes during his 17 years in charge. He said the company at times expanded too fast and diversified too broadly, and that he did not respond to some of its crises in a way that was authentic and true to who he is. Under Tilray, the business now says it is putting people first, with a culture people are proud to be part of.
The MoodyBot probability model: what BrewDog could have saved
MoodyBot, the AI layer inside Moody At Work, reads anonymous daily mood check-ins across teams, bars and head office. It can’t fix a balance sheet. What it could have done is show leadership, every day, what staff were feeling long before they wrote an open letter.
At a business like BrewDog, the signals MoodyBot could have surfaced include sustained stress and burnout scores in bar and brewery teams, check-in reasons clustering around pressure, fear or not being heard, falling participation as staff stop believing honesty is safe, and a widening gap between how head office and frontline teams feel.
The 2021 letter was the warning, delivered publicly. Daily anonymous data could have given the board the same warning privately, and years earlier.
| Risk | Publicly reported loss | Model assumptions | What MoodyBot could have saved |
|---|---|---|---|
| Operating losses | £62.7m (2023) plus £34.1m (2024), total £96.8m | 10% to 20% linked to culture (expansion, the pandemic and market conditions also played a role); 30% to 50% chance early signals lead to action | £2.9m to £9.7m |
| Unpaid staff wages | £489,000 in wages and holiday pay not covered by administration | Owed to staff, not a company saving | Not counted |
| Enterprise value | Once said to be worth more than $1bn; assets sold for £33m | Drivers too mixed to attribute | Not quantified |
| Jobs and bars | Hundreds of jobs lost and bars closed in March 2026 | Redundancy costs not disclosed | Not quantified |
| Total quantified | £2.9m to £9.7m |
How the numbers were built: £96.8m x 10% x 30% gives £2.9m. £96.8m x 20% x 50% gives £9.7m. The culture share stays low on purpose, because Watt himself pointed to fast expansion and spending, and the pandemic hit bar-heavy businesses hard.
What every founder can take from this
Most people don’t write open letters. The CIPD data says they let it go and quietly leave. BrewDog’s staff did go public, and it still didn’t change the ending. If you only find out how your people feel when they tell the press, you’ve found out too late.
It’s the same lesson we saw with what workplace silence cost KPMG Australia.
