Best Data Enrichment Tools For 2027
1. Clay — Waterfall Enrichment From Many Providers
Clay connects to many data providers and runs them one after another until it finds a match, which raises coverage well beyond any single source. AI research steps can add custom fields, such as recent funding or hiring signals.
It suits teams that want full control over how enrichment works.
2. ZoomInfo — Deep Company And Contact Data At Scale
ZoomInfo can enrich and continuously refresh Salesforce, HubSpot and Dynamics records with firmographics, technographics, contacts and intent data. Form enrichment shortens web forms by filling fields in the background.
It is a natural fit for large teams already using ZoomInfo for prospecting.
HubSpot acquired Clearbit and rebuilt it as Breeze Intelligence. It enriches contacts and companies inside HubSpot, shortens forms and identifies companies visiting your website.
If HubSpot is your CRM, this is the simplest way to add enrichment.
4. Cognism — Compliant Enrichment With Verified Mobiles
Cognism enriches CRM records with verified mobile numbers and emails, with strong coverage in the UK and Europe. Its compliance features make it a safe choice for teams under GDPR.
Enrichment can run on demand or in bulk through CRM integrations.
People Data Labs sells person and company data through APIs and bulk datasets. Product teams use it to enrich signups, power search features or build their own models.
It is built for developers rather than sales reps, so expect to do some engineering.
6. Apollo.io — Affordable Enrichment With Prospecting Included
Apollo.io can enrich CRM records and CSV uploads from its large database, and it includes prospecting and sequencing in the same platform.
For small teams, it is often the cheapest way to fill in missing fields.
Lusha enriches lists and CRM records with contact details and company data through a straightforward interface. Reps can also enrich one record at a time with its extension.
FullEnrich focuses on one job: finding emails and mobile numbers by checking many vendors in a waterfall. It integrates with common CRMs and with Clay.
Pay-per-result pricing suits teams that only need contact fields filled.
9. Datagma — Lightweight Enrichment For Lean Teams
Datagma offers person and company enrichment through an API, Google Sheets add-on and integrations. It is a lightweight option for small teams that want enrichment without an enterprise contract.
Coverage is narrower than the larger providers, so test it on your own lists.
How To Choose A Data Enrichment Tool
What Fields Do You Actually Need?
Decide whether you need contact details, firmographics, technographics or intent. Paying for a full platform makes little sense if you only need emails and phone numbers.
Single Provider Or Waterfall?
A single provider is simpler to manage. Waterfall tools like Clay and FullEnrich raise match rates by combining sources, at the cost of more setup.
How Fresh Must The Data Stay?
Look for automatic refresh schedules if your CRM is large, since job changes quickly make records out of date.
Does It Fit Your Stack And Rules?
Confirm native CRM integrations, API limits and compliance with GDPR and CCPA before you buy.
