Why it matters
A figure is only citable when a reader can check where it came from. This page fixes the dataset, the method and the data date next to the claim itself, so a journalist, researcher or answer engine can quote the number without asking anyone for the source.
Limitations
- Counts describe Harpd Rank participation only — they are not a measure of the wider AI product market.
- A product can be listed but hold zero Rank Points; "listed" does not mean "promoted".
