Once proficiency is on the record, stop sending everyone the same thing. Beginners get fundamentals content and patient onboarding. Certified practitioners get advanced plays, beta invitations, and community leadership prompts.
Score accounts by certified density: a company with a dozen credentialed practitioners is a different expansion conversation than one with a single stalled learner. Skill-based segmentation typically outperforms firmographic segmentation for one reason — it is built on what people actually did, at length, rather than on what industry code somebody assigned them.
On the record
Certified density per account, computed and visible, is the single best expansion-readiness score most companies will ever have.
