Data enrichment fills the gaps in your contact and account records. When a lead fills out a form with just their name and email, enrichment can append their job title, company name, company size, industry, phone number, and social profiles. This additional context powers lead scoring, segmentation, routing, and personalization.
The main enrichment providers in B2B include ZoomInfo, Clearbit (now Breeze by HubSpot), Apollo, Lusha, and Clay. Each has different strengths. ZoomInfo has the largest B2B database. Clearbit excels at real-time form enrichment. Apollo combines enrichment with outbound sequencing. Clay aggregates multiple data sources through a spreadsheet interface.
Enrichment can happen at different trigger points: on form submission (real-time enrichment to shorten forms), on record creation in the CRM (automated enrichment rules), or in batch (periodic enrichment runs to refresh existing records). Real-time enrichment on forms is particularly valuable because it lets you collect fewer form fields while still getting the data you need for scoring and routing.
The cost of enrichment varies widely. ZoomInfo contracts start in the tens of thousands for annual licenses. Clearbit and Apollo offer per-record pricing that scales more predictably. Clay charges per enrichment credit. Before committing to a provider, test data quality on a sample of your existing records to see how well they match.
Enrichment is not a one-time activity. Data decays, people change jobs, and companies evolve. Set up recurring enrichment runs to keep your database current, and build logic to handle conflicts when enriched data contradicts existing values.
