B Corp certification has a three-year recertification clock and an ongoing obligation to actually live what you scored. The score you submit is verified documentation. What B Lab investigates is the gap between that documentation and what's actually happening inside the business — and complaints from employees, partner organizations, and the public can open that investigation at any point, not just at renewal.
BrewDog — the Workers pillar doesn't grade on a curve
BrewDog, the Scottish craft brewer, certified in February 2021. Less than two years later, in December 2022, it was no longer a B Corp. The sequence in between matters.
A BBC documentary aired in early 2022 featuring former employees describing a "culture of fear." A separate open letter, signed by current and former staff under the name "Punks with Purpose," made similar allegations months before the film aired. B Lab opened an investigation into claims about the company's workplace practices.
The outcome is disputed in framing, not in result. BrewDog's CEO said the company had "decided to step aside" after B Lab requested additional measures the board could not implement at the time. B Lab confirmed BrewDog was no longer certified and declined to comment further. Either way, the badge was gone.
What makes this case instructive is where the complaint landed. BrewDog's initial certification score of 81.8 out of 200 was barely above the 80-point threshold, and its highest scores were in the Workers category — the same pillar where employee accounts contradicted the numbers. The Workers pillar is also the one most frequently investigated when complaints arrive, because the complaints tend to come from employees.
"A score on the B Impact Assessment is documentation. What B Lab investigates is the gap between the documentation and what's actually happening inside the business."
Etsy — when the legal structure outgrows the certification
Etsy certified as a B Corp in 2012, three years before its IPO. When it went public, a legal conflict became unavoidable.
B Corp certification for Delaware-incorporated companies requires converting from a C Corporation to a benefit corporation, a legal structure that formally embeds stakeholder commitments into the company's governing documents. Etsy's shareholders were not aligned on that conversion, and a leadership change in 2017 settled the question. Etsy voluntarily let the certification lapse rather than restructure its legal entity.
There was no allegation of misconduct. The structure no longer fit. For a small business, the equivalent risk comes at acquisition, a new investment round, or a change in legal entity. Your governance structure is part of what you're certifying, and any significant change to it should run through the certification process before it's finalized, not after.
Havas — when your parent company's client list becomes your problem
This one is instructive because the certified entities did nothing wrong on their own.
In September 2023, Havas Media, a global advertising conglomerate, signed a contract with Shell. Havas Media was not a certified B Corp. Four of its agencies were: Havas London, Havas Lemz, Havas New York, and Havas Immerse. In July 2024, B Lab revoked all four certifications following a formal complaint from a coalition of more than 20 other certified agencies and the climate advocacy group Clean Creatives.
B Lab's reasoning was that the association with Shell through the shared Havas name breached "core community values," even though the certified agencies had no direct relationship with the Shell account. B Lab also ruled that all Havas entities are permanently ineligible for future certification, which means the ruling extended beyond the four certified agencies to the entire network.
If your business operates under a parent brand, a franchise agreement, or any shared identity with an entity making decisions you don't control, that relationship is part of your certification risk profile. The precedent here is clear: B Lab treats brand association as meaningful, and it can act on conduct that isn't yours.
B Lab investigates "material, credible and specific claims" on two grounds: intentional misrepresentation of practices during the certification process, or breach of the B Corp community's core values. Both grounds have resulted in decertification. Complaints can come from employees, other certified companies, or third-party organizations — and B Lab can open a review at any point in the certification cycle, not just at renewal.
Dr. Bronner's — the exit that wasn't a failure
Dr. Bronner's holds the highest B Corp score ever recorded: 206.7 out of a possible 200 at its 2022 recertification. In February 2025, the company announced it would not renew when its certification expired in September 2025.
The reason was not a gap in the company's own practices. It was a deliberate exit over what Dr. Bronner's described as the dilution of the certification's standards. When Unilever Australia and Nespresso certified in 2022, followed by Nestlé Health Sciences in 2023, Dr. Bronner's argued that large multinationals with documented supply chain issues now shared a logo with companies that had built serious operational track records. After B Lab published its revised V7 standard in April 2025, Dr. Bronner's reviewed the changes and stood by its decision.
This is worth separating from the other cases. Dr. Bronner's didn't fail certification. It concluded the certification was no longer saying what it used to say — and that sharing the B Corp logo with companies it viewed as using the badge for marketing purposes contradicted its own mission.
What these B Corp decertification cases mean for small businesses
None of these companies were small. BrewDog had thousands of employees across multiple countries. Etsy had gone public. Havas operates globally. Dr. Bronner's has nearly $200 million in annual revenue.
But the failure modes apply at any scale. The Workers pillar catches businesses where documented culture and actual culture diverge. Governance structure has to match what you've committed to, and changes in ownership or legal entity need to be accounted for before they're finalized. Brand association is part of the certification, and if your business shares a name or parent with an entity making decisions you don't control, that gap is yours to manage.
B Corp standards are also tightening. The 2026 standard update introduced mandatory carbon measurement and overhauled how performance is assessed across all pillars. The bar is higher than it was, and the enforcement posture has been tested by real cases.
