It listens to your PostHog events and applies your rules: when enough different people at one company start using the product, or when somebody keeps failing onboarding, it opens a follow-up with the actual events attached and creates one task on the right company in your CRM. No model decides who gets chased. The rules are arithmetic over events your product really sent, so the same activity always produces the same answer, and every follow-up shows you exactly which people did what.
