LeadMagic works to be the enrichment layer that other GTM tools call on, positioning itself as an API-first data provider built for AI agents and technical GTM builders rather than as a standalone sales tool end users log into. It shows up in practitioner conversation as one link in a waterfall, the enrichment step operators chain inside Clay alongside competing providers when one tool misses a contact, and as a subject of ongoing accuracy and cost benchmarking against the rest of the category. That conversation is dense and rising, spanning workflow walkthroughs, provider comparisons, and a founder appearance discussing AI-assisted outbound build.

Business Profile
LeadMagic was founded in 2021 and runs lean at 11 employees, reporting $1.2M in revenue. The company positions itself explicitly as infrastructure for other tools rather than a destination platform, an enrichment API that other point solutions and increasingly AI agents call into. It says it serves more than 3,000 teams and stays independent, competing on data accuracy and speed (sub-200ms response times, a pay-per-valid-result pricing model) rather than on breadth of the interface layer non-technical reps interact with.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
LeadMagic ships four parallel access paths to the same enrichment data, a REST API, a CLI, a natural-language chat interface for building prospect lists, and a Model Context Protocol server that plugs directly into agent-facing tools such as Claude, Cursor, and Windsurf. The MCP server covers contact and company enrichment, decision-maker search, and hiring and intent signals, authenticated by OAuth rather than a shared API key, with setup documentation written for each supported client.
