150+ Data Sources for ICP Discovery

Clay pulls from 150+ data vendors, including Ocean.io and HG Insights, to surface companies that match your ICP criteria. No single provider covers every market segment, so stacking sources closes the gaps your current list is missing.

Multi-Source ICP Consolidation at Scale

Blend firmographic data across vendors and deduplicate by domain and HQ address to raise account match rates from 60% to 90%+. One unified table replaces the manual work of reconciling exports from Apollo, PeopleDataLabs, and CPJ.

Frequently asked questions

How does Sculptor build an ideal customer profile?

You start by entering your ICP criteria, including company type, stage, size, and geography, into Sculptor. It then assembles a table of matching companies with fields like headcount, industry, total funding, and HQ location pulled from 150+ data vendors. From there you can layer in firmographic enrichments from providers such as Ocean.io and HG Insights, then push the finished list to HubSpot, Salesforce, or Apollo.

How accurate are the ICP company matches from Sculptor?

Account match rates typically rise from around 60% to 90% or higher when Clay stacks multiple data sources and deduplicates by domain and HQ address. Ocean.io, one of the integrated providers, reports a 95% verified company accuracy rate. Sculptor also lets you filter by headcount, funding stage, and tech stack so non-fit accounts are excluded before any record reaches your CRM.

Can I build an ICP list for thousands of companies at once?

Yes. You can paste a small seed list to test, then scale up with a CSV upload or a Clay table pipe for larger batches. Sculptor runs firmographic enrichments from providers like HG Insights and Ocean.io across every row automatically, and you can push the full output to Salesforce or HubSpot in a single sync step.

Is it legal to collect B2B company data for ICP building?

GDPR allows processing of business contact data under the legitimate interest basis (Article 6(1)(f)), but you must document a Legitimate Interest Assessment. In the U.S., CCPA/CPRA no longer exempts B2B personal information as of January 2023, so California contacts require the same privacy protections as consumers. Firmographic data like headcount and industry carries lower risk than personal data, but always check the rules for your jurisdiction.
