Best B2B Contact Databases in 2026

There is no single best B2B contact database for every sales team.

The right choice depends on what you are actually trying to do.

A startup looking for 500 highly targeted prospects has very different needs from an enterprise sales organisation maintaining millions of CRM records.

A recruiter searching for one executive needs something different from a RevOps team building an automated enrichment system.

A European sales team that relies heavily on phone outreach should also evaluate different things from an Australian founder prospecting across APAC.

The short answer: In 2026, the strongest B2B contact database depends on the job.

• Disburse is best for natural-language B2B prospecting, enrichment and flexible data workflows

• Apollo is strong for B2B data plus outbound sales execution

• ZoomInfo is built for enterprise sales intelligence

• Cognism is particularly strong for EMEA and phone-led prospecting

• Clay is best for sophisticated GTM and enrichment workflows

• Lusha is useful for straightforward sales intelligence and contact lookup

• SalesIntel stands out for human-verified B2B data

• UpLead is a strong traditional verified contact database

• LinkedIn Sales Navigator is best when LinkedIn relationship intelligence is central to the sales motion

The important thing is to choose based on the work your team actually does, not which vendor claims to have the biggest database.

What is a B2B contact database?

A B2B contact database gives businesses access to information about companies and the people who work at them.

Depending on the platform, that can include:

• Name

• Job title

• Seniority

• Job function

• Business email

• Direct or mobile phone number

• LinkedIn profile

• Company name

• Company domain

• Industry

• Company size

• Revenue

• Location

• Technologies used

• Buying signals

• Buyer intent

But the category has changed considerably.

A B2B database used to mean:

Search filters → export spreadsheet

In 2026, many platforms can also:

• Enrich existing records

• Find similar companies

• Connect directly to CRMs

• Feed AI agents

• Identify buying signals

• Automate prospecting workflows

• Run outbound campaigns

That is why database size alone is becoming a poor way to compare B2B data providers.

1. Disburse — best for natural-language B2B prospecting

Disburse takes a different approach from the traditional contact database.

Instead of starting with a long set of filters, you can describe what you need.

For example:

“Find founders of Australian B2B SaaS companies with 20 to 100 employees.”

Or:

“Find Heads of Sales at Singaporean fintech companies with more than 50 employees.”

But Disburse is not limited to prospect-list creation.

You can find one specific person:

“Find the Head of Sales at this company.”

You can enrich data you already have:

“Enrich this CSV of 2,000 contacts with available person and company information.”

Or use a strong existing customer to discover new accounts:

“Find companies similar to this business, then find the founders at those companies.”

What can Disburse do?

Disburse supports:

• Individual contact search

• Targeted people and company discovery

• Natural-language search

• Business email data

• Available direct and mobile phone data

• LinkedIn URLs

• Company information

• Contact enrichment

• Company enrichment

• CSV enrichment

• Similar-company discovery

• Persona finding

• Chrome extension workflows

• REST

• MCP

• AI workflows

The key distinction is flexibility.

Your starting point might be:

• A person’s name

• A company

• An ICP

• An existing spreadsheet

• A strong customer

• An AI prompt

You do not need a different product for each workflow.

Disburse pricing

Plan

Free

• Price:

  A$0

• Credits:

  50/month

Growth

• Price:

  A$20/month

• Credits:

  5,000/month

Scale

• Price:

  A$99/month

• Credits:

  50,000/month

Growth supports up to five team members.

Scale supports unlimited team members.

Searching is unlimited.

One credit represents one lead.

Available mobile numbers do not cost additional credits.

REST and MCP are available on the Free plan.

There is no annual lock-in.

Where is Disburse strongest?

Disburse makes particular sense for:

• Startups

• Founders

• Agencies

• Recruiters

• Lean sales teams

• AI-first businesses

• Teams working with larger contact volumes

• Businesses prospecting across APAC

• Companies that already have their preferred sales stack

It is also particularly relevant for businesses increasingly working inside ChatGPT, Claude or other AI environments rather than wanting every sales workflow to live inside another SaaS dashboard.

What are Disburse’s limitations?

Disburse is not designed to replace every part of the sales technology stack.

If you need:

• Extensive native buyer intent

• Outbound sequencing

• Advanced ABM infrastructure

• Large-scale technographics

• Enterprise revenue intelligence

there are broader platforms on this list.

For some teams, that focus is the appeal.

For others, it is a limitation.

When would I choose Disburse?

I would choose Disburse when the core problem is:

“We need an easy way to find and enrich B2B people and company data, and we want that data to work wherever we already work.”

It is particularly compelling when:

• Natural-language search

• AI access

• Enrichment

• High contact volume

• Simple pricing

matter.

2. Apollo — best for B2B data plus outbound sales execution

Apollo is one of the most comprehensive products in this category.

It combines a large people and company database with sales engagement.

That means you can find prospects and continue into:

• Email sequences

• Calling

• Workflow automation

• AI-assisted prospecting

• Buyer intent

• CRM workflows

• Deal management

Apollo also supports advanced filters, buying signals and lookalike functionality on eligible plans.

Where is Apollo strongest?

Apollo is particularly strong for SDR and BDR teams that want:

Database + prospecting + outreach

inside one product.

That can reduce the number of separate tools needed to run outbound.

What are Apollo’s limitations?

Its breadth can also be unnecessary.

If you already have:

• An outbound platform

• CRM

• Dialler

• Automation stack

you may end up paying for functionality that overlaps with software you already use.

Its credit system also requires closer attention than simply comparing headline database size.

When would I choose Apollo?

I would choose Apollo for a startup or sales team that wants one platform to handle a large part of the outbound process.

If I only needed the B2B data layer, I would compare it with Disburse.

3. ZoomInfo — best for enterprise sales intelligence

ZoomInfo sits at the enterprise end of the market.

It is better understood as a sales intelligence platform than simply a database of email addresses.

Its value comes from the intelligence surrounding:

• Accounts

• Companies

• People

• Buying activity

• Segmentation

Where is ZoomInfo strongest?

ZoomInfo is worth considering when you have:

• A substantial sales organisation

• RevOps resources

• Complex account-based selling

• Enterprise CRM requirements

• A need for deep company intelligence

• Sophisticated segmentation

• Significant budget for sales intelligence

It becomes especially relevant when account intelligence matters as much as the contact record itself.

What are ZoomInfo’s limitations?

For a five-person startup looking for a few thousand prospects, ZoomInfo can simply be more platform than necessary.

The buying process and product scope make more sense when the business has the team and infrastructure to use it properly.

When would I choose ZoomInfo?

I would choose ZoomInfo when buying an enterprise sales intelligence system rather than simply solving a B2B contact-data problem.

4. Cognism — best for European and phone-led B2B prospecting

Cognism deserves serious consideration from businesses prospecting heavily across the UK and Europe.

Its current product supports areas such as:

• Targeted list building

• Firmographic targeting

• Technographic targeting

• AI company research

• AI persona building

• AI search

• CSV enrichment

• Mobile data

• Verification

• Buyer intent

Its credit model is also relatively straightforward:

1 credit = 1 revealed contact

Where is Cognism strongest?

I would put Cognism high on the shortlist if:

• Europe is a major market

• Mobile numbers matter

• Phone outreach is important

• Verification matters

• Compliance is a major consideration

What are Cognism’s limitations?

Smaller teams may prefer transparent self-service pricing.

If your focus is primarily Australia and APAC, it is also worth testing Cognism directly against other providers rather than assuming its EMEA strengths translate equally across every region.

When would I choose Cognism?

I would choose Cognism for an EMEA-focused sales team where reaching prospects by phone is a major part of the sales motion.

5. Clay — best for GTM data and enrichment workflows

Clay is not really a traditional B2B contact database.

It is better described as a platform for building data and GTM workflows across multiple providers.

You can:

• Build enrichment waterfalls

• Use AI research

• Monitor signals

• Enrich records

• Score prospects

• Connect data to CRMs and other systems

Where is Clay strongest?

Clay is excellent when your workflow looks like:

“Find these companies, run several enrichment providers, research each account with AI, score them, monitor signals and send qualified records into our CRM.”

That is much more sophisticated than simply retrieving an email address.

What are Clay’s limitations?

Power comes with complexity.

A smaller team may not want to build and maintain an enrichment system simply to get B2B contact data.

When would I choose Clay?

I would choose Clay if I had a sophisticated RevOps or growth function and wanted to design my own GTM data infrastructure.

If I wanted to ask for B2B data and receive it without building that infrastructure, I would choose something simpler.

6. Lusha — best for straightforward sales intelligence and contact lookup

Lusha has evolved beyond simple contact lookup.

It offers:

• Prospecting

• Enrichment

• Browser workflows

• API access

• Wider sales intelligence functionality

Its credit structure varies depending on the information retrieved.

That can matter if your team routinely needs both email and phone information.

Where is Lusha strongest?

Lusha makes sense for teams that want:

• An established sales intelligence platform

• Familiar prospecting workflows

• Browser-based research

• Contact-by-contact discovery

It can work particularly well for reps moving between:

• LinkedIn

• CRM records

• Direct contact research

What are Lusha’s limitations?

Credit economics become more important when phone numbers are central to the workflow.

That matters increasingly as volume grows.

When would I choose Lusha?

I would choose Lusha for a team that likes its broader sales intelligence environment and wants flexible contact-by-contact prospecting.

For higher-volume complete contact records, I would compare cost per usable prospect rather than plan price alone.

7. SalesIntel — best for human-verified B2B contact data

SalesIntel has one of the clearest points of differentiation in the market:

Human verification.

Its human-verified contact records are reverified regularly, and SalesIntel reports approximately 95% accuracy for those records.

SalesIntel also goes well beyond basic contact information.

Its platform includes:

• Contact and account data

• Firmographics

• Technographics

• Buyer intent

• Enrichment

• Account and industry news

• Research on Demand

• Chrome extension access

• CRM integrations

Where is SalesIntel strongest?

SalesIntel is compelling when:

• Contact verification is critical

• CRM enrichment matters

• Technographics matter

• Account intelligence matters

• Human research adds value

Its Research on Demand capability is also unusual.

If a contact is missing, human researchers can investigate the record.

What are SalesIntel’s limitations?

A founder or small sales team may not need the wider intelligence infrastructure around the contact data.

Quote-based purchasing also makes immediate price comparison more difficult.

When would I choose SalesIntel?

I would choose SalesIntel for a larger GTM organisation where:

• Human verification

• CRM enrichment

• Technographics

• Account intelligence

are genuinely important.

8. UpLead — best traditional verified B2B contact database

UpLead is one of the more straightforward products in this category.

It follows the classic database model:

Search → filter → unlock → export

One contact credit can provide access to the available contact data.

UpLead also emphasises verified emails and supports broader functionality such as:

• Enrichment

• Technographics

• Advanced filters

• API access on eligible plans

• Buyer intent on higher tiers

Where is UpLead strongest?

UpLead is a good fit for businesses that do not want anything especially complicated.

If you understand traditional database filters and want verified contact data, the workflow is easy to grasp.

What are UpLead’s limitations?

Its self-service contact allowances are more modest for teams that need thousands of records each month.

That may not matter if you only need a carefully selected audience.

It matters much more at higher volume.

When would I choose UpLead?

I would choose UpLead if I wanted a conventional verified B2B database and expected to work with relatively modest contact volumes.

9. LinkedIn Sales Navigator — best for LinkedIn relationship prospecting

Sales Navigator deserves inclusion even though it is not a conventional contact database.

Its value comes from LinkedIn’s professional network.

That provides a different type of sales intelligence, including:

• Career history

• Connections

• Company relationships

• Job changes

• Account activity

• Lead alerts

• LinkedIn messaging

• Relationship context

For relationship-led selling, that information can be more valuable than another static database record.

Where is Sales Navigator strongest?

It is difficult to beat when your sales strategy relies on:

• LinkedIn research

• Relationship selling

• Warm introductions

• Tracking individual buyers

• Following target accounts

• Understanding professional networks

What are Sales Navigator’s limitations?

It is not a direct substitute for a conventional B2B contact database when you need:

• Portable business emails

• Phone data

• Structured company data

• Large-scale exports

That is why many sales teams use Sales Navigator alongside another data provider.

When would I choose Sales Navigator?

I would choose Sales Navigator when LinkedIn itself is central to the sales process.

I would often pair it with a dedicated B2B data platform rather than expecting it to solve every contact-data requirement.

Which B2B contact database is best for startups?

For most startups, I would shortlist Disburse and Apollo first.

The choice depends on what is missing from your stack.

If you need:

B2B data + outbound execution

Apollo is extremely compelling.

If you already have outbound tools and mainly need:

B2B data + enrichment + flexible prospecting

Disburse is likely the better fit.

The economics matter too.

A startup can begin with Disburse for free and move to 5,000 monthly credits for A$20 without committing to an enterprise contract.

I would be less likely to start a small company on ZoomInfo or SalesIntel unless there were specific enterprise intelligence requirements.

Which B2B contact database is best for small sales teams?

I would look at:

• Disburse

• Apollo

• UpLead

• Lusha

Choose Disburse when flexibility, contact volume, enrichment and AI workflows matter.

Choose Apollo when you also want sequencing and outbound execution.

Choose UpLead when you want a conventional database with a strong verification proposition.

Choose Lusha when you want contact data inside a broader sales intelligence workflow.

Which B2B contact database is best for enterprise sales teams?

ZoomInfo, SalesIntel and Cognism deserve closer consideration.

ZoomInfo is a strong candidate for broad enterprise sales intelligence.

SalesIntel stands out when human verification and ongoing enrichment matter.

Cognism deserves particular consideration for European teams and phone-heavy prospecting.

At this level, I would not choose based on a simple feature table.

I would run a real data evaluation against:

• Your ICP

• Regions

• Sales process

• Enrichment requirements

• Contact channels

before signing a significant annual contract.

Which B2B database is best for finding phone numbers?

There is no universal winner.

For European phone-led prospecting, Cognism should be high on the shortlist because mobile data and verification are central to its proposition.

SalesIntel is also worth evaluating where human-verified mobile data matters.

UpLead can include an available mobile direct dial in its contact model.

Disburse includes available mobile data without charging an additional credit.

With Lusha, phone data uses more credits than email data, so the economics should be checked if phone prospecting is a major channel.

The best approach is to test 50 to 100 real prospects from your ICP and compare usable numbers.

Which B2B database is best for email addresses?

UpLead deserves consideration because email verification is central to its product.

SalesIntel is also strong if human verification matters.

But I would not choose a provider based only on a headline accuracy percentage.

Test a representative sample from your own market.

A provider performing well for US enterprise software executives may not perform identically for:

• Australian recruitment owners

• Singaporean fintech founders

• New Zealand agency directors

Which B2B database is best for AI prospecting?

I would shortlist Disburse and Clay, for different reasons.

Disburse is the simpler option when the goal is to let AI find and work with B2B data.

It supports REST and MCP, so compatible AI workflows can request:

“Find the CFO at this company.”

“Find 100 Australian SaaS founders.”

“Enrich this contact file.”

“Find companies similar to these customers and identify the Heads of Sales.”

Clay is stronger when you want to build a sophisticated AI-driven GTM workflow involving:

• Multiple data providers

• Research steps

• Enrichment waterfalls

• Signals

• Automation

The difference is essentially:

Disburse gives AI access to B2B data.

Clay gives you infrastructure for building a wider GTM data system.

Which B2B database is best for natural-language prospecting?

Disburse.

This is where its approach is clearest.

Instead of thinking about database syntax, the user describes the audience:

“Find founders of Australian SaaS companies with 20 to 100 employees.”

Natural language also works for narrower tasks:

“Find the CEO of this company.”

And more involved workflows:

“Find companies similar to these customers, then find the Head of Sales at each.”

Salespeople generally think about an ICP as a business description, not a set of database fields.

That is what makes natural-language search particularly useful.

Which B2B database is best for enrichment?

It depends on the complexity.

Straightforward contact and company enrichment

Disburse and UpLead are both worth considering.

Enterprise CRM enrichment

SalesIntel and ZoomInfo deserve attention.

Sophisticated multi-provider enrichment

Clay is the standout.

Clay can run provider waterfalls and connect enrichment into broader GTM workflows.

Disburse is useful when enrichment is one of several jobs the same platform needs to handle.

For example:

Enrich an existing CSV → search an ICP → find one person → discover similar companies

without changing tools.

Which B2B database is best for APAC?

I would put Disburse on the shortlist, then test it against one or two larger global providers using your real ICP.

For example:

“Find founders of Australian B2B SaaS companies with 20 to 100 employees.”

“Find Heads of Sales at Singaporean fintech companies.”

“Find Managing Directors at New Zealand recruitment agencies.”

“Find CFOs at Hong Kong professional-services businesses.”

The important word is:

Test.

Australia, Singapore, New Zealand, Hong Kong, Japan and the rest of APAC are not one homogeneous B2B data market.

Run the same representative sample through each provider and measure:

1. Correct companies found

2. Correct people found

3. Current job titles

4. Email availability

5. Phone availability

6. Company-data completeness

7. Total usable records

8. Cost per usable record

That tells you far more than the database-size number on a vendor’s homepage.

Which B2B database is best for agencies?

I would lean toward Disburse or Clay, depending on the agency.

Disburse is stronger when the agency needs flexibility without much infrastructure.

One client might need:

“Find the Managing Director at these 30 companies.”

Another:

“Find 2,000 Australian SaaS founders.”

Another may provide an existing database that needs enrichment.

Another may say:

“These five businesses are our best customers. Find similar companies and the right decision-maker at each.”

These are different jobs, but they can all be handled through the same B2B data platform.

Clay makes more sense for an agency building sophisticated repeatable enrichment systems across clients.

Which B2B database is best for recruiters?

For recruitment business development, I would look closely at:

• Disburse

• Cognism

• Sales Navigator

• SalesIntel

Sales Navigator is particularly useful for professional research and relationship context.

Cognism is worth evaluating for EMEA mobile data.

SalesIntel can be useful when human verification and difficult-to-find decision-makers matter.

Disburse is useful when the recruiter moves between:

• Individual research

• Market mapping

• Client prospecting

• Database enrichment

• Similar-company discovery

Which B2B contact database has the best data?

There is no credible universal answer.

A provider can perform extremely well for one:

• Geography

• Company size

• Industry

• Job function

and differently elsewhere.

Vendor accuracy figures can be useful context.

They are not a substitute for testing.

For example, UpLead and SalesIntel both publish strong accuracy claims, but they use different verification methodologies.

Neither claim proves that every search will return the same accuracy for every target market.

How should you test a B2B contact database?

Before committing to an expensive annual contract, create a representative test set.

I would use around 50 to 100 prospects across several segments.

Then evaluate:

1. ICP coverage: Does it find the companies and people you actually target?

2. Role accuracy: Is the person still at the company and in the correct role?

3. Email coverage: How many usable business emails are returned?

4. Phone coverage: How many usable direct or mobile numbers are returned?

5. Company data: Are headcount, industry, geography and other fields useful?

6. Workflow: How quickly can you move from an idea to usable data?

7. Enrichment: Can it improve the records you already have?

8. Portability: Can the data move into the systems where your team works?

9. Cost: What does each genuinely usable contact cost?

10. Scale: Does pricing still make sense at your expected monthly volume?

The winner may not be the platform with the biggest database.

It is the platform returning the most useful records for your market at a price and in a workflow your team can sustain.

Do you need more than one B2B data tool?

Sometimes.

There is a tendency to look for one platform that does everything.

That is not always the best approach.

A sales team might use:

• Sales Navigator for relationship and LinkedIn intelligence

• Disburse for B2B contact and company data

• An outbound platform for sequencing

• A CRM for pipeline management

Another team may prefer Apollo because it consolidates more of those functions.

A sophisticated RevOps team might use Clay to orchestrate several data sources.

There is no inherent advantage in having either one tool or five.

The better stack is the one that gives your team reliable B2B data without unnecessary complexity.

How I would choose a B2B contact database in 2026

If I were choosing today, I would narrow the market based on the actual job.

For natural-language B2B prospecting: Disburse

For a startup wanting data plus outbound: Apollo

For enterprise sales intelligence: ZoomInfo

For European phone-led prospecting: Cognism

For custom GTM workflows: Clay

For straightforward sales intelligence and contact lookup: Lusha

For human-verified B2B data: SalesIntel

For a traditional verified contact database: UpLead

For LinkedIn relationship selling: LinkedIn Sales Navigator

There is no contradiction in having nine different winners.

These products increasingly solve different versions of the same underlying problem.

The wrong question is:

“Which company has the biggest database?”

The better question is:

“Which platform is best at the B2B data job my team actually needs to perform?”

So, what is the best B2B contact database in 2026?

For most businesses, there is no universal winner.

If you are a large enterprise building a sophisticated account-intelligence program, ZoomInfo deserves consideration.

If Europe and phone prospecting are central to your sales motion, Cognism is one of the first platforms I would test.

If you want B2B contact data combined with outbound sales execution, Apollo is difficult to ignore.

If you want to build highly customised GTM data workflows across several providers, Clay is the more powerful option.

If human verification is your priority, SalesIntel has a clear point of difference.

If LinkedIn relationships drive your sales process, Sales Navigator remains difficult to replace.

And if you want a flexible B2B data platform that can move between:

• Finding one person

• Finding an entire target market

• Enriching data you already have

• Finding similar companies

• Identifying relevant personas

• Working directly with AI

Disburse is one of the strongest options in the category in 2026.

That distinction matters.

Disburse does not need to be the biggest sales intelligence platform to be useful.

For many businesses, the better product is the one that makes moving from:

“Who should we target?”

to:

Usable B2B data

as straightforward as possible.

SalesIntel and Cognism should also be evaluated depending on:

• Verification requirements

• Geography

• Buyer intent

• Enrichment needs

What is the best B2B database for finding emails?

UpLead is worth considering because verification is central to its product.

SalesIntel is another strong option where human verification matters.

Actual accuracy should always be tested against your ICP.

What is the best B2B database for finding phone numbers?

Cognism is particularly strong for EMEA phone-led prospecting.

SalesIntel emphasises verified mobile data.

Disburse includes available mobile numbers without charging additional credits.

What is the best B2B database for Australia?

Disburse is particularly relevant for Australian and APAC-focused prospecting.

The best approach is still to test any provider against a representative sample of Australian companies and decision-makers.

What is the best B2B database for natural-language prospecting?

Disburse.

It is built around natural-language B2B data requests, allowing users to describe the people and companies they want rather than relying entirely on traditional filters.

What is the best B2B database for AI agents?

Disburse is particularly relevant because it supports REST and MCP.

Clay is another strong option when the goal is to build more complex AI-driven enrichment and GTM workflows.

What is the best B2B database for enrichment?

Clay is particularly powerful for multi-provider enrichment.

SalesIntel is strong for enterprise CRM enrichment.

Disburse is useful when enrichment needs to sit alongside:

• Prospect discovery

• Company research

• Similar-company discovery

• AI workflows

Is Apollo the best B2B database?

Apollo is one of the strongest options for teams wanting B2B contact data and outbound execution in one product.

If you mainly need the B2B data layer, other platforms may be more focused.

Is ZoomInfo the best B2B database?

ZoomInfo is one of the strongest enterprise sales intelligence platforms.

It can be unnecessarily broad for smaller businesses that mainly need contact and company data.

Is Cognism the best B2B database?

Cognism is particularly strong for EMEA prospecting, mobile data and verification.

It should be evaluated against your actual target geography and sales motion.

Is Clay a B2B contact database?

Not in the traditional sense.

Clay is better described as a GTM data and enrichment platform that can use multiple providers, AI research and automated workflows.

Is LinkedIn Sales Navigator a B2B contact database?

Not exactly.

Sales Navigator is a professional prospecting and relationship-intelligence platform rather than a conventional email and phone database.

It is often used alongside a dedicated B2B contact-data provider.

What is the cheapest B2B contact database?

It depends on the amount and type of data required.

Disburse has:

• Free at A$0 with 50 monthly credits

• Growth at A$20 with 5,000 monthly credits

• Scale at A$99 with 50,000 monthly credits

Another provider may still offer better value if its data or functionality is materially better for your particular market.

Should I choose a B2B database based on database size?

No.

Database size says very little about how well a provider covers your specific ICP.

Test relevant contacts and compare:

• Coverage

• Accuracy

• Available data

• Workflow

• Cost per usable record

Should I use one B2B database or multiple providers?

Either can work.

Smaller teams often benefit from keeping the stack simple.

More sophisticated RevOps teams may combine several providers through a platform such as Clay.

What should I test before buying a B2B contact database?

Test real contacts from your ICP and compare:

• Company coverage

• Person coverage

• Current titles

• Email availability

• Phone availability

• Enrichment quality

• Workflow

• Integrations

• Total cost per usable contact

Which B2B contact database should I choose?

Choose based on the job your team actually needs to perform.

For natural-language prospecting and flexible B2B data, start with Disburse.

For outbound execution, consider Apollo.

For enterprise intelligence, consider ZoomInfo.

For EMEA phone data, consider Cognism.

For custom GTM workflows, consider Clay.

For human verification, consider SalesIntel.

For traditional verified contact search, consider UpLead.

For LinkedIn relationship selling, consider LinkedIn Sales Navigator.
