Crustdata

Crustdata is a real-time B2B data broker that delivers live company and people data through APIs, data feeds, and bulk datasets. Backed by Y Combinator and serving hundreds of enterprise customers, Crustdata provides a data infrastructure layer purpose-built for AI agents, sales automation, recruiting platforms, and investment workflows. The platform indexes over 60 million companies and 1 billion people profiles, refreshed continuously from multiple sources of truth including LinkedIn, company websites, SEC filings, job boards, social media, and news outlets.

How It Works

Crustdata organizes its data products around two main delivery methods. The real-time API provides credit-based access to live company signals such as headcount changes, funding rounds, leadership moves, job postings, and social media activity. Developers integrate via a REST API with flexible filtering, pagination, and webhook-based alerts. For teams that do not require real-time data, Crustdata also offers flat-file company and people datasets unified from 11 or more trusted sources, delivered monthly as CSV or JSON. These bulk datasets can be filtered by funding stage, headcount, industry, geography, and many other attributes.

Key Capabilities

• Company Search and Enrichment: Query and enrich company profiles by name, domain, industry, location, headcount range, funding history, and technology stack. Retrieve up-to-date attributes like total funding raised, employee growth metrics, web traffic trends, and Form D filings.
• People Search and Enrichment: Search for individuals by name, job title, company, location, and skills. Access profile attributes including current and past roles, education, certifications, social media links, and open-to-work signals.
• Real-Time Signals and Alerts: Monitor people and companies for changes such as job switches, promotions, new hires, departures, funding announcements, product launches, and web traffic spikes. Webhooks push notifications the moment a signal is detected.
• AI Agent Integration: Crustdata works natively with AI agents through an MCP (Model Context Protocol) server, allowing tools like Claude to query real-time company and people data directly within conversational workflows.
• Bulk Data Delivery: Full company and people datasets available for download, refreshed monthly. Suitable for enrichment of internal CRM systems, analytics pipelines, and machine learning models that do not require live API calls.
