Best B2B Data Providers in 2026: 14 Databases Compared on Coverage, Credits and Compliance

By Laurel · Updated Oct 22, 2026

If your buyers are mostly in Europe and you dial mobiles, start with Cognism. If you want the biggest self-serve pool at the lowest entry price, start with Apollo.io. If you sell into large North American accounts and have the budget for an annual platform contract, ZoomInfo is still the reference point. If you want a small, credit-based contact reveal tool for a handful of reps, Lusha, UpLead, LeadIQ and SignalHire all sell that shape of product. And if you need firmographics and corporate hierarchies rather than direct dials, D&B Hoovers is built for it.

This page is about the database itself. Which provider has usable contact and company data for your region and segment, how it says it keeps that data fresh, and what contract you sign to get it. It isn't a review of prospecting workflows, sequencers or visitor-ID tools. For the wider category of sales intelligence software, start with our guide to the best sales intelligence tools. Here we compare 14 providers on three questions that decide whether a data purchase pays off: coverage by region and data type, the credit model and contract shape, and the compliance rules that govern the records once they're in your CRM.

One caution up front. Every database size and accuracy figure in this article is the vendor's own claim, linked to the vendor page, and none of those numbers have been tested against your market. The way to settle it is to run a sample before you sign, and the testing section below shows how.

Key Facts

• Salesforce's State of Sales report puts selling at 40% of a rep's week, with 60% spent on other work, and says 46% of sales pros with agents report data quality issues hurting their sales.
• The median US worker had been with their current employer for 4.1 years in January 2026, and the BLS reports a 3.2% total separations rate in August, so a share of any contact list goes stale every month.
• France's data regulator fined contact-data vendor Kaspr EUR 240,000 in December 2024 for collecting LinkedIn members' contact details they had restricted.
• The FTC says do-not-call violations carry civil penalties of up to $53,088 each, and the TCPA lets recipients recover $500 per violation.
• The UK ICO fined a company GBP 160,000 in May 2026 for more than 700,000 unsolicited sales calls, including calls to numbers on the corporate TPS register.

Quick Comparison Table

Use this to narrow 14 vendors down to three. Prices are the vendor's own published figures with their billing term; "Pricing on request" means the vendor publishes no figure.

Coverage by Region

Regional coverage is where data buying goes wrong most often. Vendors publish global totals; you sell into a specific market. The table below shows what each vendor's own pages say about geography, and where they say nothing. "Not stated" means the pages cited in this article don't print it, so ask for it in writing.

Two patterns stand out. First, only a few vendors tell you anything about Europe specifically: Kaspr publishes a European contact count, LeadIQ publishes a lower match rate for EMEA than for global, and Cognism publishes a list of the regions where it screens phone numbers. Second, none of these vendors lists a Southeast Asia record count on the pages cited here, so ask for one in writing. If your pipeline sits in Singapore, Malaysia, Indonesia, the Philippines or Vietnam, treat every global number as unproven for your market and run the sample test below with a list of your own accounts in those countries.

North America is the best-documented region, mostly because the compliance machinery around it (CCPA, the FTC Do Not Call registry, state data broker registers) forces vendors to say more. That's a documentation advantage, not necessarily a data quality one.

Data Types: Firmographic, Contact, Mobile and Intent

"B2B data" bundles four different products, and a provider can be strong in one and thin in another. Buy for the type that limits your pipeline today.

If you only need the data attached to records you already hold, a separate class of tools does that job, and we cover them in our data enrichment roundup. If your need is specifically finding addresses, the email finder tools guide and the LinkedIn contact finder guide go deeper than this page can.

Refresh and Verification Practice

No vendor can promise a record is current today. People change jobs, and the BLS tenure figure shows a median stay of 4.1 years, which means a large share of any large list moves over a few years. What differs is how each vendor says it handles that.

Read these as claims about methods, not guarantees of outcomes. The useful distinction is between vendors that publish a refresh interval (Cognism, Lead411, Kaspr) and vendors that publish a single accuracy percentage with no interval. An interval tells you how long a bad record can sit in the database. A percentage doesn't.

Credit Models and Contract Shape

The credit model decides what a contact really costs you. Two vendors with similar sticker prices can differ several-fold per usable phone number.

The shape matters more than the price per credit. A self-serve credit plan (Apollo, Lusha, UpLead, LeadIQ, SignalHire) lets you start this week and stop next month. An annual platform contract (ZoomInfo, Cognism, HG Insights) gives you more data and a negotiator, but you commit before you've seen your own connect rate. If you're still choosing between the two shapes, our guide to choosing sales intelligence software walks through the buying process.

Compliance: GDPR, PDPA, CCPA and Phone Consent

Buying data doesn't transfer the legal duties that come with using it. This section describes the rules at a high level and links the primary sources. It isn't legal advice, so have counsel review your own outreach.

The EDPB case is the one to read before you sign. The French regulator fined Kaspr EUR 240,000, citing breaches of GDPR articles 5, 6, 12, 14 and 15, after its browser extension pulled LinkedIn members' contact details into a database the regulator put at about 160 million contacts. The lesson isn't that one vendor is off limits. It's that "GDPR compliant" on a badge is a marketing claim, and the question for any provider is where the contacts came from and how people are told.

Practical questions to put in writing to every shortlisted vendor:

1. Where do the contacts come from (public sources, contributory network, partners, scraping)?
2. How and when are data subjects notified, and how do you honour deletion requests?
3. Is phone data screened against do-not-call lists for each country you'll dial, and how often?
4. Is the vendor registered as a data broker where required?
5. What happens to your own uploaded data, and is it used to enrich other customers' records?

Stage Fit Matrix

Sizing and Persona Table

1. ZoomInfo: The Platform Contract With the Largest Stated Pool

ZoomInfo sells a platform, and its pricing page says so plainly: you pay by edition, number of licenses and credit usage, with one credit equal to one export of a contact or company profile. Sales editions are Professional, Copilot Advanced and Copilot Enterprise. Marketing editions are Demand (75,000 included credits), ABM Lite and ABM Enterprise (150,000 included credits). Payment frequency is negotiated, and integrations need a minimum bulk credit purchase.

On data, ZoomInfo's data page claims 500M+ professional profiles, 122M+ company records, 300M+ emails and 135M+ direct dial numbers, plus 96% email deliverability and 87% mobile number accuracy. It lists more than 4,500 intent topics, and badges for SOC 2 Type II, ISO 27001, ISO 27701, GDPR and CCPA. There's a free ZoomInfo Lite for business email users who aren't premium subscribers, with a monthly credit allowance that doesn't roll over.

No list price is published. Vendr reports a median annual contract value of $33,500, with a range of $7,247 to $156,032 across 1,578 purchases (reported). Treat that as a negotiating reference, not a quote.

Best for: Mid-market and enterprise teams that want data, intent and workflow under one contract. See best ZoomInfo alternatives for cheaper shapes.

2. Apollo.io: Self-Serve Data With a Free Plan

Apollo is the lowest-friction way to test a large database. Its pricing page lists Free at $0, Basic at $49 per seat per month billed annually ($65 billed monthly), Professional at $79 ($99 monthly) and Organization at $119 with a three-seat minimum (annual only). Annual plans grant credits upfront: 30,000 per seat per year on Basic, 48,000 on Professional, 72,000 on Organization. Free gets 900 credits per seat per year, granted monthly.

Credit costs are where the budget goes: an email costs 1 credit and a phone number 8. Credits pool across the team and don't roll over, including add-on credits. Features marked unlimited sit under a fair use policy with no numeric cap published. Apollo's data page claims 240M+ contacts, 30M+ companies and 98% email accuracy, with SOC 2 Type II, ISO 27001 and GDPR compliance based on legitimate interest. Ask for its written position on do-not-call screening before you dial from it.

Best for: Teams that want to start outbound this week with data and sequencing together. Compare options in best Apollo alternatives.

3. Cognism: Phone-Verified Mobiles With Do-Not-Call Screening

Cognism's pricing page publishes plans (Standard and Pro) but no price. It's seat-based with five seats included, each carrying credits, and one credit reveals one contact. Re-viewing a revealed contact is free; you're charged again only when that contact changes jobs. There's no stated free trial, but you can get a demo and a free data sample. For like-for-like replacements, see the Cognism alternatives.

The data case is regional. Cognism says its phone-verified mobiles connect up to three times more often and that Director-and-above data is refreshed every 30 days. Its compliance page lists GDPR and CCPA coverage, do-not-call screening for the UK (TPS and CTPS), the US, Australia, New Zealand and several European countries, ISO 27001 and ISO 27701, SOC 2 Type II, and a California data broker registration. Cognism also owns Kaspr, acquired in 2022.

On price, an Amplemarket write-up citing Vendr reports roughly $15,000 for the platform plus about $1,500 per user per year on Standard, and about $25,000 plus $2,500 per user on Pro (reported, Amplemarket). Confirm current figures with Cognism.

Best for: Outbound teams in Europe and the UK that dial mobiles and need screening built in.

4. Lusha: Flat Plans With Seats Bundled

Lusha prices the plan, not the seat. Its pricing page shows Free at 40 credits a month, Starter at $49.90 a month billed monthly or $37.45 billed annually ($449.10 a year) for 400 credits a month or 4,800 a year, Pro at $69.90 monthly or $52.45 annually ($629.10 a year) with two free seats, and Premium at $399.90 monthly or $299.95 annually ($3,599.10 a year) with five free seats. Scale is custom, with Lusha saying 50% or more off the price per credit.

Email costs 1 credit and a phone number 5. CSV or CRM exports cost 1 credit per 1 to 25 results. Monthly plans roll unused credits over up to 2x the monthly cap; annual credits are issued upfront and reset at year end. The homepage claims 515M+ contacts, 29M+ companies, 98% email accuracy and 85% US and 86% global phone accuracy, with GDPR (ePrivacyseal), CCPA (TrustArc), SOC 2 Type II and ISO 27701 listed. The plan comparison includes a Do Not Call list row.

Best for: Small teams of one to five who want a predictable monthly bill.

5. D&B Hoovers: Firmographics and Hierarchies First

Dun and Bradstreet's pitch is company data. Its data page cites 650M+ entities in the D&B Commercial Graph. The enterprise D&B Hoovers page lists no price and offers a free trial request. A smaller self-serve tier, D&B Hoovers Essentials, costs $49 a month for 150 company and 150 contact credits, or $529 a year for 1,800 of each, with the first month free and auto-renewal at the list price then in effect.

Vendr reports a median of $41,400 a year across 109 Dun and Bradstreet purchases (reported), but that covers all D&B products, not Hoovers alone. Clearlake Capital completed its acquisition of D&B on August 26, 2025, making it a private company.

Best for: Marketing and RevOps teams building account lists and territory models where company structure matters.

6. UpLead: One Credit for Email Plus Mobile

UpLead's pricing page is the simplest on this list. A 7-day trial gives 5 credits. Essentials is $99 a month billed monthly or $74 a month billed annually for 2,040 credits a year; Plus is $199 monthly or $149 a month billed annually for 4,800 credits a year; Professional is custom and annual only. Extra credits cost $0.60 on Essentials and $0.50 on Plus.

One credit equals one contact and unlocks email and mobile direct dial together, which is cheaper per usable record than vendors that charge separately for phones. UpLead claims a 95% accuracy rate on email verification. Free, Essentials and Plus are single-user accounts, so a team means Professional.

Best for: An individual rep or founder who wants a cheap, predictable cost per contact.

7. Lead411: Verified Contacts With Buyer Intent on Annual Plans

Lead411's pricing page has a 7-day Pilot Light trial with 50 exports, then Spark at $49 a month for 1,000 exports a month or $490 a year for 12,000 exports (annual includes Buyer Intent). Ignite starts at $150 a month for 1,000+ exports with API access, or $1,500 a year with intent as an add-on. Blaze is pricing on request with unlimited exports a year. Unused exports roll over on all plans.

The vendor says emails are "triple verified" (SMTP, human and open validation) and re-verified every three to six months, with direct dials "double verified". It lists itself as a Texas-registered data broker and links CCPA and Do Not Sell controls. No database size is published.

Best for: Small outbound teams that want published verification practice and intent signals at a low annual price.

8. RocketReach: Pay for Found Contacts, Mind the Caps

RocketReach prices per seat on its pricing page. Monthly plans are Essentials $49, Pro $99 and Ultimate $209, with lookups capped at 100, 250 and 1,000 a month. Annual plans start from $399 a year on the US list, with Ultimate at $1,699 a year. Annual plans carry "unlimited" lookups, but the fair-use FAQ sets a cap of 10,000 lookups a month, and bulk lookups, API calls, CSV and CRM pushes count as exports (1,200, 3,600 or 20,000 a year by tier), not lookups.

Lookups are only charged if a verified email or phone is found. A free account gets 5 lookups, and team plans start at $6K annually. The vendor claims 700 million professionals, 60 million companies and 98% accuracy, lists SOC 2 Type II and ISO 27001 on its security page, and publishes CCPA request metrics in its privacy policy. Annual prices differ by region, so confirm the figure you'll be billed.

Best for: Individual lookups and light API use where you only want to pay for hits.

9. Seamless.AI: Real-Time Search and a Bulk Quote

Seamless.AI doesn't publish a price on its pricing page; you request a quote based on contacts per month, with unlimited users, bulk credits, volume discounts and a switch-from-competitor credit of up to 50%. The homepage offers a free plan of up to 50 credits and refunds a credit automatically when an email is invalid. It positions itself as a real-time search engine, not a database, so there's no database size to compare.

It lists GDPR, CCPA, SOC 2 Type II and ISO compliance. Vendr shows plan tiers (Free, Pro with daily credit refresh, Enterprise) but no price figure, so get a quote before you plan around it.

Best for: Teams comfortable with a quote process who want real-time search and bulk volume.

10. LeadIQ: Capture From LinkedIn Into the CRM

LeadIQ's pricing page offers a free plan with 1 user and 50 credits. Pro has a credit slider with five users included: 200 credits a month costs $20 billed monthly or $15 billed annually, and the top slider tier of 6,750 credits costs $290.25 a month on monthly billing. Enterprise is annual only, contact us. Credits cost 1 for an email, 10 for a phone number, 11 for both and 3 for account enrichment. Any plan has a 30-day free trial.

The vendor claims 750 million+ profiles with up to 200 million re-verified monthly, an 85% global mobile match rate (70% for EMEA) and phone accuracy above 90%. It says every supplier passes a GDPR and CCPA compliance review. LeadIQ is independent, with a $30M Series B in 2021.

Best for: SDRs capturing contacts while browsing LinkedIn and pushing them into a CRM.

11. Kaspr: A European Contact Pool With a Regulatory History

Kaspr prices per user on its pricing page, in euros, pounds and dollars. Starter is EUR 45 a month billed annually or EUR 59 monthly (about $49 or $65, GBP 39 or 51) with unlimited B2B email, 100 phone credits a month and 5 direct emails. Business is EUR 79 billed annually or EUR 99 monthly ($79 or $99, GBP 69 or 85) with 200 phone and 200 direct email credits a month. Organization is annual only with a five-user minimum. A free plan has a small monthly allowance. Phone add-ons start at EUR 0.35 each. Credits roll over on paid plans, and the "unlimited" claim carries a 10,000 credits per account per month fair-use cap.

Kaspr claims 200 million+ European B2B contacts from 120+ sources, with emails re-validated every two months. It says it's "GDPR and CCPA aligned." Read that alongside the CNIL's EUR 240,000 fine in December 2024, and ask about changes made since. Cognism bought Kaspr in 2022.

Best for: European sales teams that want low-cost reveal and are prepared to do compliance diligence.

12. Leadfeeder (formerly Dealfront): Company Data Rooted in Europe

Dealfront became Leadfeeder on March 24, 2026. The rebrand FAQ calls it a brand change only, with contracts remaining with Dealfront Group GmbH, Germany GmbH and Finland Oy. Prices on the pricing page are in euros: Lite is free (last 100 companies a month, 20 credits), Discover starts at EUR 79 a month billed annually or EUR 113 monthly, Activate from EUR 369 annually or EUR 527 monthly, Scale from EUR 599 a month annual only, and Enterprise is custom. There's a 14-day trial, plan credits don't roll over at contract end, and add-on credits last two years.

Leadfeeder is closer to company-level intelligence tied to website visitors than a contact database, and it publishes no database size. It does suit teams that want a European vendor under EU entities. For alternatives, see best Leadfeeder alternatives.

Best for: European teams that want company-level data and visitor identification in one tool.

13. HG Insights: Enterprise Technology-Spend Data

HG Insights sells account-level technology and spend data. Its pricing page lists Starter, Growth and Enterprise plans under "HG Copilots" (Data Studio, Market Analyzer, Sales Copilot), priced on request by seats, intelligence credits and leads processed. The standard term is two years, with one year at a higher price and quarterly billing at a premium. Credits are allocated annually, distributed monthly with a maximum 20% monthly rollover. There's no free trial.

The homepage claims 70M+ companies. Vendr reports a median of $90,000 a year, with a range of $31,498 to $173,119 across 46 purchases (reported). HG Insights announced its acquisition of TrustRadius in June 2025. For the technographic angle, see our technographic data providers guide.

Best for: Enterprise RevOps and marketing teams sizing markets by technology footprint.

14. SignalHire: Unlimited Users and Pay-on-Success Credits

SignalHire's pricing page offers a free tier with 5 credits (10 credits a month with the browser extension). Email plans are $49 a month for 600 credits or $69 for 1,000 on monthly billing; annual plans are $469 a year for 7,200 credits or $689 a year for 12,000 (shown as $39 and $57 a month). Phone and email-and-phone plans run $49 for 300 credits or $69 for 435 monthly, and $469 or $689 a year for 3,600 or 5,400. "Unlimited" email is $79 a month monthly or $63 a month billed annually; unlimited email and phone is $99 monthly or $83 billed annually, with a fair-use cap of 2,000 credits a month.

A credit is spent only when at least one email or phone is returned, all plans have unlimited users, and credits are shared. The vendor claims 900M+ profiles and 30M+ companies with no accuracy percentage, and states GDPR and CCPA compliance in its privacy FAQ.

Best for: Small teams or recruiters who want shared credits without per-seat costs.

How to Test a Data Provider Before You Sign

Vendor accuracy numbers are marketing until you test them against your market. A fair test takes about two weeks and costs little, because every vendor above offers a free plan, trial or sample (Cognism offers a data sample on request, D&B Hoovers Essentials has a free first month, and Lead411, UpLead and LeadIQ offer trials).

A few rules keep the test honest. Use the same list for every vendor so you compare like with like. Split results by region, because a vendor that wins in North America can fail in Southeast Asia. Don't tell vendors which competitors you're testing. And record the credit cost of every reveal, because a cheap credit can hide an expensive phone number.

Whichever vendor comes out on top, write the test results into your agreement as an acceptance threshold. Many annual contracts let you walk away only in the first 30 days, so run the test inside that window if you can't run it before signing. For an ICP-aligned sample list, see our library on ideal customer profile, and for how data feeds your pipeline, the prospecting strategy guide.

How to Choose

If you're comparing against enrichment-only tools, our lead data enrichment library page explains where a database ends and an enrichment layer begins, and intent data covers the signal side.

What to Do Next

Pick two or three providers from the How to Choose table, build one sample list of 200 to 300 accounts that mirrors your real regions and titles, and run the bounce, mobile connect and credit-burn tests in the same two weeks. Send the compliance questions to every vendor at the same time. Then sign the one that wins on cost per usable contact in your market, and write the test thresholds into the contract.
