Apollo
Stands out: A large people database plus email sequences in one login, with MCP and a Chrome extension.
Watch out: Data quality varies by segment, and it does not match enterprise tools for intent data and org charts.
Not the right fit for
- Buyers who need enterprise-class intent and org charts
- Teams that want an ATS
People Data Labs
Stands out: A free API sandbox, then self-serve Pro with contact data, premium fields and CSV enrichment on monthly or annual terms.
Watch out: Free hides email, phone and address. Annual saves 20% but is paid up front. Bulk data licenses are Enterprise and custom priced.
Not the right fit for
- Non-technical users who need a prospecting UI
- Buyers who need emails on the free plan
