The business was real. The conditions were not. Growth, revenue, valuations — all genuine in the moment, all contingent on an external environment that was temporary, not structural. Leaders in this zone did not misread their business. They misread the world around it — and assumed permanence where there was only a window.
The ZIRP-era company scaled on free capital. The pandemic business scaled on forced behaviour. The regulatory darling scaled on policy conditions that reversed. The dot-com play scaled on a market that didn't yet exist at the required size. In each case the metrics were accurate. The error was treating them as proof of something durable.
DZ3 is dangerous precisely because it looks like success until the moment it doesn't. The numbers validate the model. The team believes the model. Investors believe the model. The model is real — it just depends on conditions that will not last. By the time those conditions shift, the business has typically been built, capitalised and committed to a scale that assumes they will.
