Crustdata

Crustdata is a B2B data platform built for agents rather than for a dashboard. It continuously indexes the public web into a single live graph of people and companies, then exposes that graph through REST APIs, flat-file feeds and a Model Context Protocol server that drops the whole dataset into an agent in one line of configuration.

Coverage is the headline: more than 1 billion people and over 60 million companies. Company records are enriched with 250+ live datapoints and people records with 90+, spanning headcount trends, open roles broken down by function, funding history and investors, detected tech stack and web-traffic estimates on the company side, and job history, tenure, promotions, skills, education and verified contact details on the people side.

The API splits into a few clear pieces. People Search and Company Search run live queries against the graph. People Enrichment and Company Enrichment resolve an email, profile URL or domain into a full record. The Jobs and Posts APIs cover listings and social activity. The Watcher API is the distinctive one — it monitors entities and fires real-time signals the moment something changes, so a job change, a promotion or a funding round reaches your workflow as an event rather than as a row you notice on the next weekly refresh.

That event model is what makes it a fit for AI SDRs, recruiting platforms, VC deal-sourcing tools and customer-success teams: the trigger for outreach is usually a change, not a static attribute. Crustdata is a Y Combinator company and says it reached $10M ARR running its own go-to-market entirely on its own APIs.

Pricing is credit-based across usage tiers with monthly and annual plans, alongside monthly-refreshed flat-file datasets and custom enterprise arrangements; figures are quoted rather than published, and sample data is available on request. Note that people data of this kind carries real compliance obligations — check GDPR and CCPA scope before wiring it into outbound workflows.
