About Signal Watcher

Crustdata is a real-time B2B data broker that monitors over 350 B2B datapoints and provides real-time alerts for users to take action. It offers real-time company and people data via API or data feed, powering platforms with accurate, up-to-date business insights. The platform features a 'Watcher API' for real-time signals on key people and accounts, tracking promotions, job changes, and funding rounds. Crustdata aims to be a 'Google for AI agents' by providing specialized data tailored for AI platforms and agents. Additionally, it offers a full dataset delivered in bulk (CSV or JSON) for those who don't require real-time updates, covering 12M+ companies and 250M+ people profiles, refreshed monthly, quarterly, or yearly.

How to Use

Users can access Crustdata's services through a flexible REST API for real-time queries, allowing them to screen companies based on various criteria like headcount, growth, funding, and location. They can also receive live alerts on changes to people and companies they track. For bulk data needs, users can obtain a full dataset delivered as CSV or JSON. The platform also supports powering AI agents and automating workflows with dynamic, real-time data integration.
