The two solve different jobs. Apollo is built for sales teams running outreach inside one platform, including verified emails and phone numbers. Captain Data is built for developers and product/GTM engineers who want real-time people and company data via a clean REST API (and MCP for agents), and who handle outreach, if any, elsewhere. Captain Data does not provide email or phone enrichment.
