The best B2B data providers in 2026, compared

The best B2B data providers in 2026 are ZoomInfo, Apollo, Cognism, Lusha, Seamless.AI, UpLead, Kaspr, Hunter and Dealfront. They differ in regional coverage, data types (emails, mobiles, company data, intent) and pricing model. The right one is the provider with the best match rate on your own target list at a price you can sustain.

Prices below come from each provider's own site as of Oct 2026; where a provider does not publish prices, we say so. GTM Plays, our product, is not a data provider, so it is not on this list; see the end for where it fits.

How we picked these providers

We looked at the providers named most often in current "best B2B data providers" search results and checked each one's own site. We kept providers that:

• sell B2B contact or company data as their core product
• explain their data types and how credits or seats work
• publish prices, or say clearly that pricing is quote-based

We did not score data accuracy, because accuracy varies by country, industry and seniority, and any single figure would mislead. Instead, the section below explains how to test it yourself.

Pricing (as of Oct 2026, hunter.io/pricing): a Free plan with 50 credits a month.

Best for: European and global teams that want to know which companies visit their site.

Watch out for: visitor identification shows companies; you still need to pick the right person.

How to test data quality before you buy

Data providers all claim high accuracy. The only test that matters is your own market.

1. Build a test list. Pick 100 people from your ideal customer profile whose details you already know, such as current customers or contacts in your CRM.
2. Run them through each provider. Use free plans or trials where you can.
3. Measure three things: how many records the provider finds (match rate), how many emails pass verification, and how many phone numbers reach the right person.
4. Check freshness. Count how many job titles and companies are out of date.
5. Compare cost per usable contact, not list price.

Where GTM Plays fits

A database tells you who exists. It does not tell you who is ready to talk. GTM Plays works the other way round: its AI agent finds people showing intent signals on LinkedIn, scores fit against your ICP, and writes and sends messages from your own LinkedIn account. Replies arrive in one inbox, where you take over. It does not book meetings by itself.

GTM Plays includes credits for email and phone enrichment and connects to HubSpot, Salesforce, Pipedrive, Zoho CRM, Attio, folk, Breakcold, Instantly, Smartlead, SmartReach, HeyReach, Slack, Clay and Zapier, plus webhooks, a REST API and an MCP server, so it can sit alongside any provider above. Pro is $149 a month with a 7-day free trial; you can start a trial here.
