12 Best B2B Data Providers and Vendors in 2026

Quick summary:

The best B2B data provider depends on where you sell, your budget, and whether you want an all-in-one suite or waterfall enrichment: ZoomInfo for US enterprise data, Apollo.io for small teams that want data and outreach together, Cognism for Europe, and Clay for building your own waterfall. FullEnrich is the best B2B data provider overall for data accuracy: verified emails and mobile numbers in any region, found through waterfall enrichment across 20+ providers.

FullEnrich is our product. It's #1 on this list, and its entry lists its limits like every other one.

What makes a B2B data provider good, and how did we pick these 12?

A good B2B data provider sells the data type you need, holds up in the countries you sell into, lets you check its accuracy, and charges you for data you can use. We picked these 12 B2B data providers (also called data vendors) from G2's reviewer segments, each vendor's pricing page and terms, practitioner write-ups, and what we see buying data from 20+ providers every day.

• The data type you need: contact data from a B2B contact database, firmographics, technographics or buying intent. Few vendors sell all four well.
• Coverage in your region: coverage is built country by country, so test the markets on your list before you look at total database size.
• Accuracy you can check: run a few hundred contacts you already know through the tool and count how many are right. Then plan for data decay: the US Bureau of Labor Statistics put median job tenure at 4.1 years in January 2026, and RevOps writer Jeff Ignacio estimates that "Roughly 20% of CRM contacts change jobs each year."
• What you pay for: found data, searches, exports or seats. A credit spent on an empty lookup or a dead number raises your cost per usable contact.

Critics of waterfalls make two fair points. After three or four sources, adding more rarely finds much, and Rome Thorndike of GTME Pulse warns that "Cheapest-first waterfalls may return lower-quality data for records that both providers can match."

We agree with both. The providers you pick for each region, and the order you run them in, matter more than how many you stack, which is why our waterfall reorders itself for each contact's country.

Why trust us?

No data provider is good everywhere. That's the first thing you learn when you stop owning a database and start buying from twenty of them.

I co-founded FullEnrich and run its product. For every contact, our waterfall asks 20+ providers in turn, starting with the ones that are strongest in that person's country.

So I judged each provider below on three things: which data it really sells, where that data holds up, and what you pay for it.

The 12 best B2B data providers at a glance

Vendor pricing pages and G2, October 2026. Breeze has no G2 listing of its own, so its rating is Clearbit's.

Waterfall enrichment providers

Waterfall providers query several data sources in a row for each contact and keep the first answer that holds up. Waterfall enrichment suits teams that sell into more than one country, because no single source covers every market.

1. FullEnrich

FullEnrich G2 rating: 4.8/5 (247 reviews)

Three data points per contact: a mobile, a work email and a personal email.

FullEnrich is a waterfall enrichment platform that finds verified work emails, personal emails and mobile numbers for B2B contacts. It's the best B2B data provider overall for data accuracy: verified emails and mobile numbers in any region, found through waterfall enrichment across 20+ providers.

The waterfall is built around geography. FullEnrich picks the order of providers from the contact's location, so a lead in Germany starts with the sources that cover Germany best. Every email then has to pass three verification engines, and one disagreement removes it.

Teams keep ZoomInfo for intent or Apollo for sequences and send their lists to FullEnrich, run it as a step in Clay, or let an AI agent enrich prospects mid-chat through our MCP server.

Best for: the most accurate verified emails and mobile numbers in any region, from one waterfall across 20+ providers.

Key features

• Waterfall enrichment: 20+ providers in sequence, until one returns data that passes verification.
• People and company search: build a list by title, seniority, industry, headcount and location, then enrich it in the same place.
• Reverse email lookup: turn a sign-up email, work or personal, into a name, title and company.
• MCP server and API: let Claude or your own agent find and enrich prospects without opening the app.

Pros

• Your credits only go on data you get: a lookup that finds nothing is free, and so is a landline returned instead of a mobile
• The highest valid-email coverage of 14 tools in a June 2026 benchmark run by Anymail Finder, a competing email finder: 87.1% of 5,000 decision-makers across the US, UK, France and Germany
• The whole team gets access: unlimited users on every plan
• Leftover credits stay usable for 3 months on monthly billing and a full year on annual billing

Cons

• Not an outreach tool: you'll need another tool to send emails or dial
• Mobiles cost 10 credits each, so a phone-heavy list uses credits ten times faster than emails

Pricing: the free trial comes with 50 credits and no card. Pro starts at $29/month for 500 credits. Each verified work email uses 1 credit and each verified mobile uses 10. Start with 50 free credits.

The cost per credit falls as monthly volume rises.

2. Clay

Clay G2 rating: 4.6/5 (234 reviews)

Each provider fills the rows the one before it left empty.

Clay is a GTM data orchestration platform that connects to 150+ data and AI providers, so you can build your own enrichment waterfall. GTM engineers choose it to set which provider runs first and what happens to each row afterwards. The emails, phone numbers and company details it returns come from those providers, with phone enrichment starting on the Launch plan.

Clay bills on two meters. Data Credits pay for data bought from providers in its marketplace, starting at $0.05 each, and Actions pay for the platform work, from under a cent. An enrichment that returns nothing costs neither, and bringing your own API keys skips Data Credits entirely.

What you're paying for is orchestration. The provider list, the order and the repairs when a provider changes its API all sit with you. Clay's no-charge rule covers enrichments that return no result.

When a provider returns data that turns out to be invalid, Clay refunds the Data Credits only if that provider refunds Clay. Unless someone documents the setup, it's also easy to lose track of which provider filled a cell.

Best for: building your own enrichment waterfall across 150+ providers, for teams with a GTM engineer to run it.

Key features

• Waterfall builder: chain providers from a marketplace of 150+ and stop at the first valid match.
• Bring your own keys: plug in contracts you already pay for and use only Actions on top.
• Job change and signal tracking: watch accounts and contacts for moves, then trigger the next step in the same table.

Pros

• Full control of the order, so you decide which provider runs first for each segment
• A free plan with 100 Data Credits and 500 Actions a month is enough to prototype a waterfall

Cons

• Cost per row is hard to forecast: two meters, and how many providers a row touches depends on the list
• Upkeep falls on your team: a provider that changes or degrades can quietly weaken a waterfall until someone notices

Pricing: free plan, then Launch at $167/month billed yearly or $185 month to month, and Growth at $446/month billed yearly. Before you commit, see how Clay's two meters add up on a real list.

Each Clay plan lists actions and data credits separately.

Skip it if you want checked emails and mobile numbers without building or maintaining a waterfall. If you already live in Clay, FullEnrich runs inside it as a provider: the FullEnrich Clay template adds separate work email and mobile columns.

Sales intelligence data provider

Suites sell their own contact and company database together with the tools to work it: intent, signals, sequences or a dialer. Sales teams that want one login and one contract buy them.

3. ZoomInfo

GTM Workspace (ZoomInfo) on G2: 4.5/5 (9,205 reviews)

GTM Studio fills ZoomInfo's gaps with 25+ outside vendors.

ZoomInfo is a sales intelligence suite that sells contact data, company data, technographics and buyer intent under one contract. It's the default for mid-market and enterprise teams selling into the US, where its data is deepest.

What you pay for is exports. A ZoomInfo credit is spent each time a contact or company profile leaves the platform, and the price depends on seats, features and credit volume.

Since GTM Studio, a missing email or mobile triggers a waterfall across 25+ outside vendors at no extra cost, but only when ZoomInfo has nothing of its own. A ZoomInfo record that's out of date doesn't trigger it.

That's where the trade-off shows. The suite is built on US data, and teams that sell into the UK, Germany or the Nordics tell us whole account lists come back thin. Others find job titles that lag LinkedIn by a few months. Many keep ZoomInfo for intent and run their contact lists through FullEnrich.

Best for: deep US contact, company and intent data on one platform, for mid-market and enterprise sales teams.

Key features

• Contact and company data: search people and accounts by role, seniority, industry and company size, so one tool builds both the account list and the contact list.
• Buyer intent: see which accounts are researching topics you sell into.
• GTM Studio waterfall: fill missing emails and mobiles from 25+ outside vendors.

Pros

• One contract covers contacts, company data, technographics and intent, so smaller tools don't pile up
• Deep coverage of US companies and contacts, its home market

Cons

• Credits are spent on every export, including CRM syncs, so volume drives the bill
• Data outside the US is thinner, so a European pipeline often needs another source

Pricing: custom quotes based on seats, features and credit usage. Because every export spends a credit, the credit volume in this ZoomInfo package breakdown shapes the bill alongside the seat count.

Skip it if your list is mostly UK, German or Nordic accounts, or you only need emails and mobiles. These ZoomInfo competitors are lighter options.

4. Apollo.io

Apollo.io G2 rating: 4.7/5 (9,850 reviews)

The data page opens on a free sign-up.

Apollo.io is a sales intelligence suite that pairs its own B2B database with sequences, a dialer and a Chrome extension. A free plan or a $49 seat covers finding people and contacting them from one login, which is why many small outbound teams try it first.

Everything draws on a single credit pool. An email never costs more than 1 credit per contact, a phone number costs 8, and leftover credits expire at the end of each billing cycle, purchased add-ons included.

Apollo also runs a waterfall across 20+ outside vendors, but its own data fills each field first and the waterfall only covers the gaps.

Apollo's data is deepest in the US and patchier in smaller European markets. Teams we work with that sell into France and the UK usually keep Apollo's sequences and dialer and run their lists through FullEnrich for verified mobiles.

Best for: data, sequences and a dialer in one low-cost tool, for small outbound teams getting started.

Key features

• Sequences and dialer: email steps and calls run on the contacts you just searched.
• 65+ search filters: job changes, new hires, funding rounds and company news turn the database into a trigger list.
• Bombora intent: third-party intent topics show which accounts are researching what you sell.

Pros

• Cheap to start: a free plan, then $49 a seat
• Job-change and funding filters give reps a reason to reach out today

Cons

• Mobile lists drain the plan: each number costs 8 credits, and leftovers vanish when the cycle ends
• Coverage drops in smaller European markets: building a waterfall for a Dutch SaaS scale-up, GTM consultant Erik Hooijer found that "Apollo is strong in the US, weak in NL/BE."

Pricing: Apollo's free tier grants 900 credits per seat each year, spread across the months, and Basic is $49 per seat a month on annual billing with 30,000 credits per seat a year. Whether a plan is enough comes down to mobiles, and this Apollo plan math prices them at 8 credits each.

Yearly billing grants Basic's credits upfront.

Skip it if your reps call more than they email, since phone credits are where Apollo plans run out. For calling-heavy teams, our list of Apollo alternatives is the next stop.

5. Seamless.AI

Seamless.AI G2 rating: 4.4/5 (5,421 reviews)

Seamless pitches itself as an AI prospecting platform.

Seamless.AI is a sales intelligence suite built around real-time contact search, with buyer intent, job changes and CRM enrichment in the same product. Very large lists are the draw for US small businesses that need thousands of contacts fast.

Every price goes through sales, and the pricing page leads to an inquiry form. A credit-back program covers email addresses found invalid during verification, and those credits "may be" returned.

Volume is the selling point, and precision is what it costs: lists built there often need a second source for the phone numbers reps actually dial.

Best for: building very large US prospect lists fast, for high-volume small-business sales teams.

Key features

• Real-time search: contacts researched when you search, across emails, cell phones and direct dials.
• Buyer intent: flags accounts showing interest in your topics, so reps start with companies already researching the problem.
• Job changes: tracks contacts who move, so a champion's new company becomes a lead.

Pros

• A very large pool to search, 1.8B+ business emails on the vendor's own count, for teams that need thousands of contacts a month
• Switching mid-contract costs less, with offers matching up to 50% of the remaining value

Cons

• Lists need a second check before sending: a Seamless.AI G2 review found that "Sometimes the contact information isn't accurate or up to date, so finding verified leads can take extra time."
• Phones have no safety net: the credit-back program covers invalid emails only

Pricing: no public prices; budgeting starts with a demo and a quote.

Skip it if phone numbers matter more than list size. UpLead, further down this list, includes a contact's direct mobile in the same credit as the email.

Contact databases provider

A B2B contact database sells emails and phone numbers from records it collects and verifies itself. Teams buy one when its home region and its verification method match the people they call.

6. Cognism

Cognism G2 rating: 4.5/5 (1,377 reviews)

Cognism leads with phone-verified mobiles.

Cognism is a contact database built for European sales teams, with mobile numbers its team has verified by phone. Someone rang those numbers and confirmed the right person picked up, so teams calling the UK and Europe shortlist it.

Credits follow the person. One credit reveals one contact, opening that contact again later is free, and the credit only gets spent again if the person changes jobs. The data is also cross-checked against 16 do-not-call lists, from the UK's TPS to registries in France and Germany. Coverage still varies inside Europe, so test the countries you call before you sign.

Best for: phone-verified mobiles and DNC-screened data in the UK and Europe, for sales teams that call.

Key features

• Phone-verified mobiles: numbers confirmed by a call that checks the right person answers.
• Do-not-call screening: data checked against 16 DNC lists, including the US, UK, France and Germany.
• One credit per person: re-opening a revealed contact is free until they change jobs.

Pros

• Verified numbers connect more often: Cognism puts them at 3X more likely to connect, from an independent organisation's calls to 1,000 mobiles
• Do-not-call screening across 16 territories takes compliance work off the rep

Cons

• Quality varies by country, even in Europe: a reviewer invited by Cognism wrote that "Cognism's data quality is not uniform in every market. It lacks reliable data in my market, Spain."
• Phone verification covers only part of the database, and verifying the rest on demand is a premium feature

Pricing: Cognism tailors quotes to the product mix, team setup and expected usage, with 1 credit per revealed contact; a Cognism quote breaks it down.

Skip it if most of your pipeline is in the US, since Cognism's data is built around European calling. For a US-weighted list, Cognism alternatives with deeper North American data fit better.

7. Lusha

Lusha G2 rating: 4.3/5 (1,671 reviews)

Lusha now pitches itself as a data layer for GTM teams and AI agents.

Lusha sells emails and phone numbers through a browser extension, revealed while reps prospect on LinkedIn. Reps who look people up one at a time like the low friction, with a free plan and prices on the page.

A phone reveal from Lusha's own data costs 5 credits. On every paid plan, Lusha's waterfall charges only when it finds a match, at 2 credits per work email and 8 per phone. The waterfall only runs on contacts Lusha already has, so it improves records in its own database and won't find people missing from it.

Phones from that waterfall need care, since numbers returned by waterfall vendors aren't scrubbed against do-not-call lists. Annual plans also reset unused credits at the end of the year. Coverage holds up well in France, Benelux and DACH, so some teams keep Lusha for their European reps.

Best for: quick email and phone lookups from LinkedIn on a free or low-cost plan, for individual reps.

Key features

• Browser extension: reveal contact details on LinkedIn without switching tabs.
• Data waterfall: outside vendors fill gaps in Lusha's records, charged only on a match.
• Signal Score (API teams): a single buying-activity score between 0 and 1 for each record, to rank who gets called first.

Pros

• Free to start: 40 credits a month, no card needed
• Teams on the API can rank records by buying activity before reps start dialing

Cons

• Whole accounts can come back empty: a Lusha G2 review found it "Hard to find the relevant prospects in companies as they aren’t populated or it's outdated."
• Waterfall phones need your own DNC check before anyone dials

Pricing: Lusha's free tier gives 40 credits each month; Starter is $37.45/month billed yearly for 4,800 credits a year, and Premium $299.95/month billed yearly for 40,800 credits a year. Phones cost more credits than emails, so the Lusha credit math depends on your mix.

Annual plans hand over the year's credits upfront.

Skip it if your team dials US numbers at volume from waterfall results, since those arrive unscrubbed.

8. SalesIntel

SalesIntel G2 rating: 4.3/5 (540 reviews)

SalesIntel now calls itself a pipeline generation platform, built on AI automation and human-verified data.

SalesIntel sells contact records that people check as well as software, at one flat price. Mid-market US teams that want verified contacts and technographics without counting credits are its core buyers.

The pitch is a flat fee for checked data. Credits are unlimited for every user each month, and SalesIntel claims 95% accuracy. Your bill doesn't move with usage, and records go through a 90-day refresh cycle. That promise is easy to test on your own data: pull 200 contacts, pull the same 200 again 60 days later, and count what changed.

Best for: human-verified records refreshed every 90 days at one flat price, for mid-market US sales teams.

Key features

• Human-verified contacts: AI and human checks on a 90-day refresh cycle, so fewer emails bounce on people who moved.
• Verified mobiles: direct numbers checked on the same 90-day cycle, so reps dial fewer dead lines.
• Technographics: 42,000+ technologies tracked, for filtering accounts by their stack.

Pros

• The budget stays put however much the team exports
• Records are refreshed on a 90-day cycle, so you know how often they are re-checked

Cons

• Reviewers want more contacts: a reviewer invited by SalesIntel wrote that "While the contacts are well verified, increasing the quantity could greatly enhance the service."
• A flat fee pays back only at heavy usage, which is hard to judge before a demo

Pricing: request pricing; SalesIntel sells "unlimited data and enrichment, all at a single price."

Skip it if you can't test it on your own markets first, since SalesIntel's site doesn't list the regions it covers.

9. UpLead

UpLead G2 rating: 4.7/5 (833 reviews)

UpLead puts its accuracy guarantee next to its database counts.

UpLead is a contact database that verifies each email at the moment you export it, with technographic filters on top. Small teams buying US-heavy lists month to month pick it because the plans are public and need no annual contract.

Verification happens on the way out. Every export triggers an email check, and UpLead backs it with a 95%+ accuracy guarantee, so lists leave the platform freshly checked for a team that sends the same week it exports.

The homepage promises refunds for bounces and poor data. The terms say subscription fees are non-refundable and disclaim the accuracy of the data. Verification also can't tell you the person still holds the job or fits your list, because a mailbox can keep accepting mail long after its owner left. Check titles by hand on a sample before a big send.

Best for: emails verified at the moment you export them, on month-to-month plans, for small US teams.

Key features

• Export-time verification: each email is checked when it leaves for a download or a CRM.
• Mobile phones: direct mobile numbers alongside verified emails, so one export covers both email and call steps.
• Technographics: filter accounts by the technologies they use, from the Plus plan.

Pros

• Public monthly prices, so you can start and stop without a sales call
• Technographic filters help small teams target accounts by their stack

Cons

• Subscription fees are non-refundable: UpLead refunds bounces, but the terms make fees non-refundable and disclaim data accuracy
• A small monthly allowance: 170 credits on monthly Essentials runs out fast on a real campaign

Pricing: Essentials costs $99/month for 170 credits, or $74/month billed yearly for 2,040 credits a year. The cost per contact on each UpLead plan shows where yearly billing pays off.

The monthly view opens with a 7-day free trial.

Skip it if your campaigns run on lists exported weeks earlier, since the email check happens only at export.

Company and intent data: which accounts to work, and when

Company and intent providers fill in company fields or rank accounts by buying signals, and sell contact data only as a side product or a separate purchase. Marketing and RevOps teams buy them to decide where reps should look.

10. HubSpot Breeze Intelligence

Clearbit listing on G2: 4.4/5 (632 reviews)

Enrichment suggestions appear inside the CRM record.

HubSpot Breeze Intelligence is the data enrichment inside HubSpot's Smart CRM, built on Clearbit, which HubSpot acquired in 2023. HubSpot teams use it to fill missing company and contact fields on records they already hold.

There's no separate contract. Enrichment works from the first name, last name and business email submitted to HubSpot.

Breeze completes records you already hold, and it won't go looking for new people. A sign-up with a Gmail address gives it little to match, and it isn't built to supply mobile numbers for a calling team.

Best for: filling company fields inside HubSpot without another tool, for teams that already run on HubSpot.

Key features

• Automatic CRM enrichment: keeps contact and company records complete as data changes.
• Form enrichment: fills fields when someone submits a form, so forms can ask for less.
• Lead scoring inputs: enriched company data feeds HubSpot's automated scoring.

Pros

• Works inside the CRM, so reps never leave HubSpot to see company data
• HubSpot reports its international coverage on par with the US, which helps teams selling abroad

Cons

• Needs a business email to start, so personal-address sign-ups stay thin
• Built for record completion, so a calling team still needs a source of mobiles

Pricing: no extra charge on any paid Smart CRM plan. For what the product cost before it moved into HubSpot, see Clearbit's old pricing.

Data enrichment comes with the paid Smart CRM plans.

Skip it if you need mobiles or emails for people who aren't in HubSpot yet. Keep Breeze for company fields and add contacts through FullEnrich's HubSpot integration, which pushes verified data into your records.

11. 6sense

6sense G2 rating: 4.2/5 (1,570 reviews)

6sense sells prediction: which accounts to prioritize and when.

6sense is an intent and account intelligence platform that predicts which accounts are getting ready to buy. Account-based marketers buy it for one thing: a score of buying stages across the whole account list.

Its buying stages estimate how likely an account is to open or move an opportunity forward in the next 90 days. Contact data is a separate purchase: packages pair Sales Intelligence with Data Credits, Predictive AI or both, and one credit unlocks a person's emails or phone numbers only if the data exists. So you buy a ranking of accounts first and pay for people second.

The ranking tells reps where to look. It doesn't hand them someone to call, so the people at those accounts come from a contact source or from 6sense's separate Data Credits. FullEnrich works as that contact source: send it the people at flagged accounts and it returns their emails and mobiles. The scoring also leans on the US, and European teams selling to smaller companies often see fewer accounts light up.

Best for: spotting which accounts are getting ready to buy, for account-based marketing teams.

Key features

• Predictive buying stages: each account's likelihood of opening or progressing in the next 90 days.
• Buyer signals: research activity rolled up to the account level, so marketing sees which accounts are researching before anyone fills a form.
• Data Credits: unlock emails and phones for people at those accounts.

Pros

• Account scoring tells marketing and sales which slice of the list to work this quarter
• Predictions can be bought without the contact data, if you already have a source

Cons

• Campaign engagement doesn't always come with names: a reviewer invited by 6sense disliked "Being unable to see or pull the contacts that are interacting with our campaigns"
• Reps can end up buying data elsewhere: one r/gtmengineering user reported in April 2026 that "The reps start to buy their own contact data because it's awful on the platform."

Pricing: three packages, all quoted after a demo. The ZoomInfo vs 6sense comparison sets them against the biggest suite.

Skip it if you need people to call this week more than a ranking of accounts, or your team is too small to run account-based programs.

Data APIs: raw records for your own product

A data API sells person and company records by the call, for developers to build into software. Product and data teams buy it, usually to power a feature their own customers use.

12. People Data Labs

People Data Labs G2 rating: 4.3/5 (17 reviews)

A sample profile shows the fields PDL can return.

People Data Labs is a data API that sells person and company records to developers. Product and data teams use it to put those records inside their own software.

You pay per match, and you decide what counts as one. A request parameter makes sure you're only charged for responses that include the fields you asked for. Every match also carries a likelihood score: at 2, there's roughly a 10-30% chance it's the person you requested, and PDL recommends 6 or above where accuracy matters.

That control assumes someone writes the code. Records arrive through APIs and data feeds, and the free plan leaves contact data out, so testing email and phone coverage means paying for the Self-Serve plan first. The profiles are strongest on career history; contact fields are the thinner part, so teams that need US mobiles for calling usually add a second source.

Best for: pay-per-match person and company data through an API, for developers building it into a product.

Key features

• Person enrichment API: send what you know about someone and get back a full profile.
• Required fields: pay only for responses that contain the fields you need.
• Likelihood score: a confidence value on every match, with a threshold you choose.

Pros

• A clear accuracy dial, so precise use cases can demand a high likelihood score
• Self-serve from $98 a month, with monthly or annual plans

Cons

• Contact coverage can't be tested for free: the free plan excludes contact data
• Engineering time comes first: nothing works until someone builds the integration

Pricing: free up to 100 credits a month, without contact data; Self-Serve starts at $98/month.

The free Testing plan leaves out contact data.

Skip it if your reps need emails and mobiles this week and nobody on the team has time to build an integration.

What can you do with FullEnrich on a list?

FullEnrich turns a list of people, from a CSV, a Clay table, your CRM or an AI agent, into verified emails and mobile numbers, and charges only for what it finds.

A target list across the US and Europe. Upload a CSV of names and companies, or build the list in Search by title, headcount and country. You get one file back with a verified work email and mobile for each contact it finds, whatever mix of countries you started with.

A Clay table that needs emails and mobiles. Keep Clay for research and signals, and make FullEnrich the step that fills contact fields. The Clay template sets it up as two columns, one for work emails and one for mobiles, and only data that passed verification comes back into the row.

HubSpot contacts with missing phone numbers. Enrich the contacts your reps need to call and push the verified emails and mobiles back to HubSpot through the integration, so reps see the numbers on the records they already work.

An AI agent that prospects for you. Connect Claude or your own agent to the MCP server, ask for heads of sales at software companies in Germany with 50 to 200 employees, and the agent searches, enriches and hands back verified contacts in the chat.

Every setup draws on the same credits. Try it on your own list with 50 free credits.

Which B2B data provider fits your team?

Pick by region, team size and the data you need: FullEnrich for verified contacts anywhere, a suite when you also want intent or sequences, and an API when you're building a product.

Get verified contacts in every region from one provider

Teams that sell into more than one region should pick FullEnrich for their contact data, because it's the best B2B data provider overall for data accuracy: verified emails and mobile numbers in any region, found through waterfall enrichment across 20+ providers. Keep a suite for intent or sequences if you need one. FullEnrich sits next to it and bills only for data that passes verification.

The workflow stays simple: pick the countries and titles you sell to, build or upload the list, get a verified email and mobile for each person, and send them to your CRM, your sequencer or the agent doing the prospecting.

Try FullEnrich on your own list with 50 free credits, no card required.

FAQ

What is a B2B data provider?

A B2B data provider sells information about businesses and the people who work there: contact data such as work emails and mobile numbers, company data such as size and industry (firmographics), technographics and buying intent. Some own a database, some query many sources in a waterfall, and some sell raw records through an API.

What's the difference between a data provider, a contact database and an enrichment tool?

A data provider is the broad term. A contact database is one kind: you search its records and reveal emails and phone numbers. An enrichment tool starts from a list you already have and fills in the missing fields, often from several sources. LinkedIn Sales Navigator is neither: it helps you find and track people but doesn't sell their emails or mobile numbers.

Which B2B data provider is the most accurate?

FullEnrich is the best B2B data provider overall for data accuracy: verified emails and mobile numbers in any region, found through waterfall enrichment across 20+ providers. Every email has to pass three verification engines, and data that fails is neither delivered nor billed. 31.53% of the data we buy fails our verification and never reaches you or your invoice.

Do I need a different data provider for each region?

With single databases, often yes. Coverage is built country by country, so a database that's strong in the US can be thin in Germany or France, and many teams end up with one contract per region. A waterfall that draws on many regional providers can cover several regions from one account.

How much does B2B data cost?

Anywhere from a free plan to an annual contract quoted by sales. Self-serve tools publish prices: FullEnrich from $29 a month, Lusha from $37.45 a month billed yearly, Apollo.io from $49 a seat. ZoomInfo, Cognism and 6sense quote on request. Compare cost per usable contact, since a credit spent on a miss or a dead number buys nothing.

How fast does B2B contact data go out of date?

By one RevOps practitioner's estimate, roughly 20% of CRM contacts change jobs each year. The US Bureau of Labor Statistics put median job tenure at 4.1 years in January 2026. That data decay hits titles and companies first, which is why recently checked data is worth more than a big archive.

Is it legal to use B2B contact data under GDPR?

Yes, when you have a lawful basis, usually legitimate interest for relevant B2B outreach, and you honor people's right to object or be erased. Choose providers that explain where their data comes from, sign a data processing agreement, and screen phone numbers against do-not-call lists where calling rules require it. If you sell into California, the CCPA also covers B2B contacts and gives them the right to know, delete and opt out of the sale of their data.

Does FullEnrich sell intent or technographic data?

No. FullEnrich sells contact data: verified work emails, personal emails and mobile numbers, plus person and company profiles and a search to build lists. For intent or technographics, pair it with a platform like 6sense or ZoomInfo and use FullEnrich for the people at those accounts.
