Business is like the game of Poker
Every poker player has met the man with one move. He plays a single style, bets a single way, and as long as the table does not adjust, he looks like a genius. Then the table adjusts — it always does — and his one move becomes the thing everyone at the table is waiting for. He does not decline slowly. He goes from feared to finished in a season, because a game with many variables cannot be survived with a single answer. A business built on one product has the same disease: it looks like focus right up until the day it is revealed as exposure.
The romance of the one-product company is powerful, and it is easy to see why. The founder’s story is always told at the moment of the brilliant product — the one drink, the one device, the one drug. What the story leaves out is what the survivors did next. The companies that lasted converted their first product’s cash into second and third streams before the first one faded. Coca-Cola sells a fountain of beverages around one flagship. Amazon began with books and now collects from retail, cloud computing, advertising, and subscriptions, each stream steadying the others. Berkshire Hathaway turned an insurance float into railroads, energy, candy, and shoes. The myth remembers the one product. The record shows the portfolio.
The single-product business lives, as the saying goes, one substitute away from the grave. Its dangers are not hypothetical; they are scheduled. A patent expires on a date printed in a government file. A technology shifts, and the product that was a necessity becomes a nostalgia item — ask the makers of dedicated word processors, of film, of the stand-alone GPS unit that every phone absorbed. A single big customer constituting half the revenue is acquired, goes broke, or brings the work in-house. Nothing has to go wrong inside the company. The company can execute flawlessly and still be executed by events, because one stream of income means one way to die.
I have sat on both sides of this table. In my law practice I watched professional firms — good ones, with fine reputations — that drew nearly all their fees from a single client or a single kind of case. When the client was bought, or the law changed, or the referral source retired, the firm discovered that what it had called a specialty was a dependency, and dependency does not negotiate. In development, the builder with one subdivision has bet his company on one town council, one school district’s reputation, one employer’s payroll. The builder with four projects in three towns is not smarter. He is playing more than one hand, and a man playing several hands can survive losing one of them.
Let me be fair to focus, because the opposite error is real. The young business that chases five products starves all five; concentration is how a small company gets its first product right and its first customers served. The sequence is the lesson. Focus is a starting strategy, not a finishing one. The first product’s job is to generate the cash and the knowledge that buy the second stream. The failure is not starting with one product — everyone starts with one product. The failure is falling in love with the purity of it, treating every proposal for a second stream as a distraction, and waking up ten years later as a monument to a single decision made in a world that has moved on.
The practical question is not whether to diversify in the abstract but what the second stream should be. The wise ones grow close to home: the product your existing customers already ask for, the service that uses the same equipment, the neighboring town that uses the same crews. Each new stream should share something with the first — customers, distribution, skill — so that it is an extension of the moat and not a fresh gamble in a stranger’s game. And the time to build it is while the first product is still strong, when diversification looks unnecessary and is therefore cheap. Building a second stream from the cash of a dying first one is the saddest arithmetic in business.
Here is the takeaway. Write down, honestly, what percentage of your income arrives from your single largest product, customer, or market. If the honest answer would frighten a poker player — and anything above half should — then the most important project in your business this year is not improving that product. It is building the stream beside it, while the first one is still paying for the construction. Nobody at the Big Table survives forever on one move. Neither will a business, however brilliant the move, however beloved the product, however loyal the customers — right up to the morning the table adjusts.
