API Signals Data
Overview
Crustdata provides real-time firmographic and people data through APIs, covering headcount growth, web traffic, funding, and LinkedIn-derived signals on private companies. It is built for teams that want to pipe fresh data into their own sourcing models, Clay tables, or internal agents rather than browse a UI. Venture funds use it to enrich watchlists on a schedule, trigger alerts on hiring inflections, and keep proprietary sourcing databases current without manual refreshes.
