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
Societeinfo
Stands out: Every plan, including free, includes API access. Credits cover company fiches, contact enrichment, and surveillance of French establishments (10 companies on free, 150 on Starter).
Watch out: No USD rate card. Unused subscription credits do not carry over. The file is France-centric (SIRENE-style company data), so it is the wrong tool for US prospecting.
Not the right fit for
- US-only prospecting teams
- Buyers who need unused credits to roll over each month
