metric snapshot
| segment | share of ai down rounds | common issue |
|---|---|---|
| middleware wrappers | 44% | weak differentiation |
| model infra tooling | 27% | long sales cycles |
| vertical apps | 19% | distribution bottlenecks |
| core model labs | 10% | capex intensity |
signal braid
- Investors now demand clearer proprietary value beyond model routing.
- Teams with deep workflow integration held valuations better.
- Pricing compression exposed fragile assumptions in quick-growth periods.
my take
The correction is rational. If your product can be rebuilt in a weekend with cheaper APIs, valuation gravity eventually catches up.
