Content mills and SEO agencies
Per-article pricing against a substitute with no marginal cost. The clients who used to buy now produce it themselves, badly, and don't care.
- ·Priced per article
- ·Buyers have moved production in-house

Generic outsourced back-office work
The billing unit is the hour, and the hour is the thing being replaced.
- ·Revenue is indexed to the unit under pressure
- 3
Thin AI wrappers with no data of their own
Your supplier is also your competitor, and they ship your feature as a checkbox at no incremental cost to your buyer.
- ·No proprietary data
- ·Feature parity arrives from the model provider

Commercial office real estate
Demand didn't come back. The debt is still there, and leases signed before 2020 keep rolling off into a smaller pool.
- ·Pre-2020 leases expiring into lower demand

Consumer subscription apps

- ·Rising paid acquisition
- ·Flat conversion
How I put this in order. This is my judgment, not a dataset. I rank on structural trouble rather than a bad quarter: shrinking demand, a cost base that can't shrink with it, and a substitute that is already good enough. The lines underneath each entry are what I'm watching, not citations.
