The Verdict
Clearbit is built for b2b marketers and growth teams, with a focus on data-enrichment and reveal-visitors. FullStory targets product teams and ux designers and leads with session-replay and heatmaps.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
