FullContact
Identity resolution and data enrichment platform for customer intelligence.
API & MCP Analysis
For AI-native operators choosing between Apollo.io and FullContact, the decision comes down to API accessibility and how easily your agent can interface with each tool.
Apollo.io has the edge here with an official MCP server, letting you connect it directly to Claude or Cursor. FullContact requires a REST API integration, which means your agent needs the API docs to build the connection.
"Claude, use the Apollo MCP to search for 50 VP Sales at Series B SaaS companies in New York, enrich their contacts, and add them to my 'Q3 Outreach' sequence."
"Claude, use the FullContact API to enrich this list of 100 email addresses with LinkedIn URLs, job titles, and current company details."
