What Can Crustdata Do? Key Features
Watcher API
Provides real-time alerts on key people and account movements including promotions, job changes, and funding rounds. The API delivers these signals the moment they happen, enabling users to act on time-sensitive opportunities. Example alerts include 'Taylor Morgan was promoted to CMO (5h ago)' and 'Payhawk listed 4 jobs (2d ago)'.
Company & People Datasets
Offers bulk access to 12M+ company profiles and 250M+ people profiles, updated monthly, quarterly, or yearly. The datasets include comprehensive information like funding history, headcount growth, web traffic trends, and social media activity. Users can query specific segments (e.g., US tech companies with 50+ employees and $5M+ funding) through flexible SQL-like interfaces.
AI Agent Optimization
Specialized data feeds tailored for AI applications, providing structured information that's optimized for machine consumption rather than human readability. The platform describes itself as 'Google for AI agents', reshaping internet data to be more useful for automated systems in sales, recruiting, and investment workflows.
Real-time Signals Dashboard
Visual interface displaying live updates about tracked companies and people, including web traffic changes (+108.4% for Podium), hiring activity (Magnitude hired 6 people), executive movements (Ryan Sullivan left Spotify), and social media posts. Updates are timestamped with minute-level precision.
Flexible Delivery Methods
Supports multiple integration options including REST API for real-time queries and CSV data feeds for bulk processing. The API allows complex filtering (e.g., companies in Austin that raised $10M in 2025) with straightforward JSON requests and responses. Bulk data is ideal for teams needing large volumes at lower cost.
