Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.
Netpeak Spider
Some scale signal, but not a Spider-specific customer count.

Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
