The Verdict
Apollo.io is built for startups and sdrs, with a focus on contact-database and sequences. Clearbit targets b2b marketers and growth teams and leads with data-enrichment and reveal-visitors.
Clearbit uses custom enterprise pricing, while Apollo.io starts at $49/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Clearbit offers broader built-in capabilities (7 features vs 6), while Apollo.io takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for growth teams — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
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.
