Hunter
Stands out: The default finder API, with MCP and a widely used free Chrome extension.
Watch out: Built around work email, so it is not a mobile-number product.
Not the right fit for
- Teams that need mobiles as the core product
- Buyers who want a sequencer in the same login
SignalHire
Stands out: Chrome extension, bulk export and built-in email sequences, with both an MCP server and a REST API.
Watch out: It runs on credits, so budget for list volume. Sequences send from your own connected mailbox, so deliverability rests on that account, not on SignalHire.
Not the right fit for
- Teams that need an ATS or CRM in the same product
- Buyers who want a flat fee instead of credits
