If you need a single platform to find prospects, enrich their data, and run outreach sequences, Apollo.io is the smarter starting point. It covers the full workflow at a lower price and gets your team operational faster.

The best teams often use both: Apollo as the operational backbone and Clay as the enrichment layer for high-value accounts. That is the stack we recommend for teams with the budget to support it.
