Why teams replace Factors.ai
The Lite/free-trial tier unmasks a limited share of visiting companies and converts to $199/month after trial; the meaningful company-unmasking rate (over 75%) and CRM sync only start on the Basic annual plan at $6,000/year, so teams wanting always-free or low-commitment usage are better served elsewhere. Predictive account scoring, dynamic audience sync to Google/LinkedIn, and enhanced Google Ads conversions are Enterprise-only ($30,000+/year), so mid-size teams wanting those specific features must buy the top tier rather than add them incrementally.
