The Verdict
Clearbit is built for b2b marketers and growth teams, with a focus on data-enrichment and reveal-visitors. CoStar targets commercial brokers and property investors and leads with property-data and market-analytics.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Clearbit has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. CoStar requires a paid subscription from day one.
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.
