I run an agency with a client list in the dozens. So the risk I think about most is not a Google update. It is dependency. What happens to a business when the customer it was built around makes a call it had no vote in?
There is a textbook version of this playing out right now, in an industry I have zero connection to. Gucci Beauty is changing hands. And the suppliers who make its bottles, caps and pumps are about to find out what that costs them.
Stay with me, because the lesson has nothing to do with perfume.
Gucci does not make its own beauty products. It licenses the name out. Coty has held that licence since 2016 and grew it into a business worth around 570 million dollars a year, by most estimates.
Now L'Oréal has taken it off them. The new licence runs 50 years and starts on 1 July 2027, a full year before Coty's deal was due to end. Coty walks away with roughly 400 million dollars and the loss of about 115 million in yearly profit. That is close to 15 percent of the company's earnings, handed over by agreement.
L'Oréal is not being modest about the plan either. The Financial Times reported that the goal is to more than triple Gucci beauty sales. L'Oréal's own luxury boss described the target as "a new multi-billion-euro house."
So the pie is about to get much bigger. Great news for everyone who supplies it, surely.
Not quite.
Here is the bit most people miss. A licence transfer is not a change of logo on the invoice. It is a full reset of the supply chain.
Every glassmaker, every cap manufacturer, every pump specialist currently on Coty's Gucci programme now has to prove themselves again to a company that never chose them. L'Oréal has its own approved vendor list. It also makes every single one of its fragrances in its own French plants. So the volume triples, and it routes straight past the incumbents.
We have seen this exact film before. When Yves Saint Laurent moved to L'Oréal, the packaging got value-engineered. Metal parts came out and metallized plastic went in. Different owner, different cost model, different suppliers.
Meanwhile the trade press caught the mood perfectly. One packaging executive said the deal "caught the supplier community completely off guard". Another admitted straight out that the dependency now worries them.
Now think about how slow this industry moves.
A glass furnace is not something you switch on next quarter. Pochet spent around 40 million euros and seven months of construction on one electric furnace, and that came after years of planning. Tooling for a metal cap runs weeks. Qualifying a new supplier runs months.
So the decisions that determine who wins Gucci volume in 2028 are being made right now, in 2026. Anyone waiting for a formal brief has already lost.
Then add the costs landing on top. The United States put a 50 percent tariff on derivative metal packaging components. Europe's new packaging regulation kicked in this August and tightens recyclability and refill rules year after year. Suppliers are facing a demand surge and a margin squeeze in the same breath.
You probably do not sell perfume bottles. Neither do I. But swap the nouns and this is a story about every business with a concentrated client base.
Pochet, for context, draws roughly 80 percent of its revenue from about 15 customers. That is an efficient business right up until one of those 15 gets bought.
I have watched smaller versions of this play out with our own clients. An agency lands a big retainer and quietly reshapes itself around that account. Then the client hires a new marketing director, or gets acquired, or brings the work in-house. Nothing went wrong with the work. The relationship simply stopped being theirs to control.
That is the uncomfortable truth here. Your best client's decisions are not your decisions. Their loyalty lives with the individual who signed you, and that individual can leave.
First, know your real numbers. Not gut feel, but the actual percentage of revenue sitting with your top three accounts. Most owners guess low.
Second, treat concentration as a live risk rather than a nice problem. If one client is over a quarter of your revenue, you are running a countdown you cannot see.
Third, build the relationship sideways. Get known by three people at the client, not one. Because when the org chart shifts, a contract protects you far less than a group of people who want you there.
Finally, watch the ownership signals. Funding rounds, acquisitions, a new CFO, a parent company restructure. The packaging suppliers who read the Kering and L'Oréal news in October 2025 had eighteen months of runway. The ones who waited for the official notice got a much shorter window.
Growth in someone else's business is not the same as security in yours. Gucci Beauty is about to get three times bigger, and plenty of the people who built it will not be there for the ride.
So the question is not whether your biggest client is doing well. It is whether you would still have a business if they made one decision tomorrow without asking you.
Go and check the number. It usually says something.
