Clearbit is designed to enrich CRM records and identify website visitors, not to act as a real-time intelligence infrastructure for AI systems.
Our APIs are built for products that need live data to function. From real-time enrichment to discovery and event tracking, it’s the infrastructure layer designed for AI agents and platforms that must move as fast as the world does.
Clearbit is not real-time
Clearbit enriches CRM records using its proprietary database. Instead of crawling the web at query time, Clearbit matches records against its maintained dataset, which is refreshed and updated every 30 days. Crustdata retrieves and enriches people and company data at the moment of request using live crawlers and real-time pipelines.

Crustdata covers more data types
Crustdata provides structured people, company, post, and event-level data across multiple verified sources. Clearbit focuses on contact enrichment, firmographics, lead scoring, and website visitor identification for marketing and sales teams.

Clearbit lacks real-time search APIs
Clearbit does not provide real-time people or company search APIs that fetch data from the web at query time. Its enrichment and prospecting workflows are database-based, updated every 30 seconds, and integrated within CRM ecosystems such as Salesforce and HubSpot.

APIs in action
Use filters to discover companies and people and build lists that get auto-updated anytime a new profile matches the criteria of your lists. Clearbit’s workflow requires searching, saving, and exporting leads into CRM or engagement tools as part of a multi-tool stack. With Crustdata’s real-time search APIs, you receive profiles that fit your criteria now instead of profiles surfaced during earlier database refreshes. With webhooks, you can track custom events to identify profiles that match your criteria immediately.

People Enrichment

All Crustdata company and people profiles are enriched with more than 350+ datapoints, including granular information such as job start and end dates, education history, job descriptions, skills, company growth signals, public web presence, reviews, and live activity signals.
