B2B contact and company database for go-to-market teams.
5 hand-curated alternatives from MintedSaaS's directory. See the ZoomInfo listing →
ZoomInfo is a B2B contact and company database that aggregates verified business data—contact names, titles, emails, phone numbers, company firmographics—into a searchable platform. It's built for go-to-market teams: sales development reps, account executives, and marketing ops who need to research companies, build prospect lists, and validate contact information at scale. The platform sits at the center of the B2B data category, bundling data enrichment, list-building, and identity verification under one subscription.
Teams use ZoomInfo in their daily prospecting workflow: searching for decision-makers at target accounts, enriching CRM records with current job titles and direct dials, and exporting lists for outbound campaigns. It's typical for a sales org with 10+ reps to license it because the cost scales with team size, while a smaller agency or freelancer might find the per-seat pricing too steep. The product assumes you're doing high-volume outbound—you'll run dozens of searches, maintain lists, and expect the data to be current within months, not years.

Clay, Hunter, Lusha, Apollo.io, and Clearbit all offer B2B contact lookup and list-building, but they differ in scope and pricing. Clay focuses on automation and custom workflows; Hunter specializes in email-finding; Clearbit does real-time verification; Apollo.io competes directly on feature parity and team size; Lusha emphasizes verified mobile numbers. Compare based on your primary use case—email-only finding, full firmographics, or multi-channel outreach.
Hunter and Clearbit both offer free tiers: Hunter includes up to 50 searches per month; Clearbit's free tier gives limited API calls for email verification. Clay has a free plan for automation workflows. None match ZoomInfo's scale or data volume for free, but they work for light prospecting or validation without cost.
You need email and phone validation to avoid wasted outreach, a search API or UI to find contacts by company and role, data freshness guarantees (ideally monthly updates), and CRM sync to push lists directly into Salesforce or HubSpot. Export limits and per-search costs also matter if you're doing high-volume campaigns.
Smaller teams under five reps should evaluate Hunter or Clearbit because per-search costs or credit-based pricing won't bankrupt you; mid-market (5–20 reps) often picks Apollo.io or Lusha for per-seat plans; enterprises often stick with ZoomInfo for compliance and volume discounts. Check whether your CRM integrations are free or add-ons, too.
Yes. Clay excels at building custom ABM workflows with data enrichment; Apollo.io and Lusha let you target entire company headcount by department; Hunter is limited to email-finding but works in campaign research. All of them can export lists for paid advertising audiences, but ZoomInfo's larger firmographics dataset gives it an edge for complex account selection.
All five do. Clay and Apollo.io have official Salesforce apps; Hunter integrates via native connectors or Zapier; Clearbit pushes verified emails directly into both platforms; Lusha has Salesforce sync built in. Check whether the integration is native, requires credits per sync, or needs a third-party tool.
Apollo.io and Lusha claim monthly or quarterly updates; Clearbit refreshes identity data in real-time via API; Hunter's email database is crowd-sourced so freshness varies; Clay relies on source data quality and enrichment partners. ZoomInfo typically updates verified records monthly. Ask for freshness SLAs in writing before signing a contract.
No major alternative offers self-hosting. All operate as cloud SaaS with data stored on their servers. If data privacy or compliance is critical, evaluate whether GDPR and CCPA compliance are documented, what's their data retention policy, and whether they allow you to control or delete prospect records.
