The Best ZoomInfo Alternative for Contact and Company Data
ZoomInfo is a go-to-market intelligence platform designed primarily for sales and marketing teams. Crustdata is built to deliver real-time, structured B2B intelligence via APIs for AI agents and data-driven products. Discover why Crustdata might be the best ZoomInfo alternative for your needs.
Why People Choose Crustdata over ZoomInfo
ZoomInfo is built primarily for human-driven sales workflows within its SaaS interface. Crustdata’s APIs are built for products that require live data to function. From real-time enrichment to discovery and event tracking, Crustdata is the infrastructure layer designed for AI agents and platforms that must react instantly to changes.
ZoomInfo lacks real-time search APIs
ZoomInfo focuses on contact data, firmographics, intent data, and sales intelligence features within its GTM platform. Its platform is database-driven and accessed primarily through its application and standard APIs. Crustdata provides real-time discovery and enrichment APIs that enable any company, person, or post to be discovered, enriched, and tracked in real time across multiple verified sources.

Crustdata is real-time
ZoomInfo updates its database regularly but does not provide enrichment at the exact moment of request. Crustdata retrieves and enriches people and company data at the moment of request using live crawlers and real-time pipelines.
Better discovery and list-building capabilities
Use filters to discover companies and people and build lists that get auto-updated anytime a new profile matches the criteria of your lists. With Crustdata’s real-time search APIs, you receive profiles that match your criteria now instead of profiles discovered during past database refresh cycles. With webhooks, you can track custom events to identify profiles that fit your criteria immediately.
