Crustdata is the real-time data layer for teams that would rather build their own tooling than buy it off the shelf. It covers 60M+ companies and 1B+ people, pulled live from 15+ sources, and reaches every team through one API, bulk datasets, and an MCP server. The platform runs on three APIs. Search finds people and companies across 350+ filters like industry, headcount, headcount growth, funding, location, seniority, title, technology, and hiring activity. Enrich turns a domain, name, or profile URL into a full record with dozens of data points, including verified work emails and phone numbers, job history, firmographics, live and historical headcount, web traffic, funding, and company and CEO approval ratings. Watch monitors the accounts and people a team cares about and fires an alert the moment something changes, like a job switch, a new role, a funding round, or a spike in web traffic. For teams working with LLMs, the Crustdata MCP exposes all three in plain language. It connects to Claude and other AI tools so research, enrichment, and monitoring run inside agents and workflows with no code.

Investment teams track founders, executives, and portfolio companies. Recruiters and agencies build sourcing tools that match the way they think. Product teams go further and ship Crustdata inside what they sell, like AI SDRs that draft outreach off live signals and recruiting agents that source and reach candidates on their own.
