ICP Scoring Rubric B2B SaaS Definition (Clear Explanation)

An ICP Scoring Rubric in B2B SaaS is a structured framework used to evaluate and rank companies based on how closely they match your Ideal Customer Profile.

If your ICP is:

SaaS companies
50–200 employees
Using HubSpot
Revenue $2M–$20M
US-based

Then you assign points for each match.

The higher the score, the better the fit.
