Best B2B data providers in 2026, compared

The best B2B data provider depends on where your buyers are and how much you can commit. ZoomInfo leads on US depth for enterprise budgets, Cognism is the common pick for European contact data, Apollo gives SMB teams data and sequencing in one tool, and Lusha and Kaspr suit smaller teams that need direct dials without an annual platform contract. Dealfront focuses on European company data, and Clay sits on top of several providers to fill gaps.

TL;DR

• Choose by region first. US-heavy and EU-heavy data coverage differ more than most demos admit.

• Annual platform contracts (ZoomInfo, Cognism) start in the tens of thousands per year. Seat-based tools (Apollo, Lusha) start under $100 per user per month.

• Test on your own ICP: pull 200 records, verify emails and call the numbers before you sign.

• In the EU, check how each vendor documents GDPR compliance and opt-outs.

B2B data providers at a glance

Pricing reflects published plans and typical contract ranges, checked September 2026. Enterprise vendors quote per deal, so treat ranges as a starting point for negotiation.

How we grouped these providers

B2B data vendors sell three different things, and mixing them up leads to the wrong purchase:

• Contact databases give you people, emails and phone numbers to prospect (ZoomInfo, Cognism, Apollo, Lusha, Kaspr).

• Company intelligence gives you firmographics, technographics and signals about accounts (Dealfront, and the account layers of ZoomInfo and Cognism).

• Enrichment layers combine several sources to fill gaps in lists you already have (Clay).

Most teams need one contact source plus, later, an enrichment layer. Few need three overlapping databases.

The best B2B data providers

1. ZoomInfo

ZoomInfo has the broadest US coverage and the deepest intent and technographic layers. Real contracts typically run from about $15,000 a year for a small entry deployment to $75,000+ for full-stack setups, with extra costs for seats, credits and add-ons such as intent data. Our ZoomInfo pricing breakdown covers the tiers in detail.

• Best for: enterprise and mid-market teams selling mainly into North America, with 10+ sellers.

• Watch out for: annual contracts, credit systems that burn fast, and renewal uplifts.

2. Cognism

Cognism is the usual choice for teams that sell into Europe and need phone-verified mobile numbers. For typical SMB and mid-market teams of three to five seats, contracts commonly land in the $20,000 to $30,000 range per year, based on our ZoomInfo vs Cognism comparison.

• Best for: outbound teams selling into the UK and EU who rely on phone.

• Watch out for: platform fees plus per-seat costs, both paid annually and upfront.

3. Apollo

Apollo combines a large contact database with sequencing, a dialer and basic enrichment. Plans run from Free to Basic ($59), Professional ($99) and Organization ($149) per user per month on monthly billing, with lower annual rates, as covered in our Apollo pricing guide.

• Best for: SMB and scale-up teams that want data and outreach in one place.

• Watch out for: European contact accuracy is weaker than specialist EU vendors, and credit top-ups add up at volume.

4. Lusha

Lusha is a quick way for small teams to get emails and direct dials through a browser extension. Annual plans run from a free tier through Starter ($37.45 per user per month), Pro ($52.45) and Premium ($299.95), with Scale as a custom contract, per our Lusha review.

• Best for: small sales teams and founders prospecting on LinkedIn.

• Watch out for: credit limits on lower tiers, and monthly billing costs roughly a third more.

5. Kaspr

Kaspr is a LinkedIn-first contact finder popular with European SDRs, with credit-based plans that suit individual sellers. See our Kaspr review for plan details and how its data compares.

• Best for: SDRs and founders who prospect mainly from LinkedIn and Sales Navigator.

• Watch out for: it's a contact finder, not a full database or account intelligence tool.

6. Dealfront

Dealfront focuses on European company data and website visitor identification. In 2026 the company markets its products under the Leadfeeder brand, with prospecting modules such as Target sold on custom quotes and covering 60 million+ companies and 400 million+ contacts, according to a ZoomInfo analysis of Dealfront pricing. The visitor identification product starts around €99 a month, with a free tier (Capterra).

• Best for: teams selling into the DACH region and wider Europe who want account-level data and web visitor signals.

• Watch out for: the modules you'll actually need are quote-based, so compare total cost carefully.

7. Clay

Clay isn't a database. It's an enrichment and workflow layer that queries many providers in sequence (waterfall enrichment) to fill gaps. See our Clay review and Clay pricing.

• Best for: RevOps teams and agencies that want the best coverage per record and have someone to build workflows.

• Watch out for: credits and complexity. It's powerful, but not plug-and-play.

How to choose a B2B data provider

1. Start with geography. Pull a sample of your real ICP in each region you sell to. Coverage gaps show up immediately.

2. Test accuracy yourself. Take 200 records per vendor, run emails through a verifier and call a sample of numbers. Our guide to email verification tools covers the first step.

3. Count real usage. Estimate exports per month, then check credit limits and overage prices.

4. Check compliance. Ask how the vendor sources data, handles opt-outs and supports GDPR requests. The GDPR's rules on lawful processing apply to you as the sender, not only the vendor.

5. Negotiate at quarter end. Enterprise vendors discount most when they're closing the quarter.

If you already have a CRM full of partial records, an enrichment tool may do more than a new database. Compare options in our lead enrichment tools guide and our email finder tools test.

FAQ

What is a B2B data provider?

A company that sells business contact and company data, such as names, job titles, emails, phone numbers, firmographics and buying signals, for prospecting, enrichment and targeting.

Which B2B data provider is best for Europe?

Cognism is the common pick for European contact data with verified mobile numbers, and Dealfront focuses on European company data. Test both on your own ICP before signing.

How much does B2B data cost?

Seat-based tools like Apollo and Lusha start under $100 per user per month. Enterprise platforms like ZoomInfo and Cognism are sold on annual contracts that typically start in the tens of thousands of dollars per year.

Is buying B2B data legal under GDPR?

B2B outreach using third-party data can be lawful under legitimate interest, but you must document your basis, tell people where you got their data and offer an easy opt-out. This isn't legal advice, so check with counsel for your target countries.

Should I use one data provider or several?

Most teams start with one contact source. Add an enrichment layer such as Clay when you need higher coverage, rather than paying for several overlapping databases.
