B2B Data Providers: The 15 Best Tools to Power Your Sales and Marketing

Choosing the right B2B data provider can be the difference between wasted outreach and real sales growth.

Sales teams don't have time to sift through bad data or chase the wrong leads.

But not all B2B data vendors are created equal.

The B2B data providers space is filled with options, each boasting unique features like LinkedIn Sales Navigator scraping, automated lead enrichment, GDPR-compliant data sourcing, or specialized data segmentation.

Top 15 B2B Data Providers Compared

Below is a deep dive into the top 16 B2B data providers.

These platforms will help you streamline lead generation, automate enrichment tasks, verify your data in real time, and ensure that you comply with major data privacy regulations like GDPR and CCPA.

Here is each one in rank order, with pricing and who it suits.

Which B2B Data Provider Is Best for Your Business?

There's no single winner. The right provider depends on your ICP, outreach motion, and budget.

1. Best for early-stage startups / solo outbound reps

Apollo.io (free tier + low-cost paid). You get 50M+ contacts, email sequencing, and basic intent signals in one tool.

It's not the cleanest data, but it's enough to test your ICP and run first outbound campaigns.

2. Best for LinkedIn-heavy prospecting

Evaboot or Kaspr. Both sit on top of Sales Navigator and clean/enrich exports in real time.

Evaboot handles bulk (500–2,500 leads per export); Kaspr gives you a Chrome extension for one-off lookups with mobile numbers.

3. Best for enterprise sales teams with budget

ZoomInfo or Cognism. ZoomInfo wins on US coverage, technographic depth, and intent data. Cognism wins on EU compliance, mobile-first contact data, and real-time phone-number verification.

Both require annual contracts starting at $15k+.

Best for GDPR-compliant EU prospecting: Cognism or Lusha. Both source EU data under GDPR frameworks and give you mobile numbers (which actually get answered in Europe).

Don't use a US-based scraper for EU lists, you'll burn your domain reputation and risk compliance penalties.

4. Best for technographic targeting (selling to companies running specific tools)

ZoomInfo (expensive, comprehensive) or BuiltWith (cheaper, tech-stack only). BuiltWith is $295/mo for 10k lookups and gives you every technology a company runs.

Pair it with Apollo or UpLead for contact enrichment.

5. Best for budget-constrained teams

Hunter.io (email-only, $49/mo for 500 searches) or Apollo free tier (10 credits/week). Both work if you're doing small-batch outreach and willing to manually verify emails.

6. Best for ABM + intent-driven outreach

6sense (enterprise-only, expensive) or ZoomInfo Intent. Both surface account-level buying signals. Use them to prioritize outreach, not replace ICP filtering.

If you're still unsure, start with Apollo (free tier) or Evaboot (if you have Sales Navigator). Run 100 leads through your outreach motion. Measure reply rate and bounce rate.

Upgrade or switch providers based on real performance, not feature lists.

What is a B2B data provider?

A B2B data provider is a company that collects, verifies, and sells contact and company information for business-to-business sales and marketing.

These providers aggregate data from public sources (LinkedIn, company websites, SEC filings), proprietary databases, user-contributed records, and web scraping, then clean, structure, and package it for prospecting, account-based marketing, and lead enrichment.

Instead of manually researching prospects one by one, you buy access to a searchable database or API that returns emails, phone numbers, job titles, company revenue, technology stacks, and buying signals filtered to your ideal customer profile.

Core data types you get from a B2B provider:

The B2B data providers space is filled with options, from all-in-one platforms like ZoomInfo and Apollo to specialized scrapers like Evaboot (LinkedIn Sales Navigator export) and enrichment APIs like Clearbit (now HubSpot Breeze Intelligence).

Most providers charge by contact credits (pay-per-email) or seat licenses (unlimited lookups per user).

A handful offer limited free tiers, though ZoomInfo's Community Edition access model changed in 2024 and may no longer be widely available.

The provider you pick depends on your ideal customer profile geography, your CRM workflow, whether you need real-time enrichment or bulk list building, and how much you care about mobile numbers and intent signals versus basic emails.

Key Factors to Consider When Choosing a B2B Data Provider

The five key factors to evaluate when choosing a B2B data provider are: data accuracy and refresh rate, GDPR/CCPA compliance, CRM and workflow integration, available segmentation filters, and customer support with data customization options.

1. Data Accuracy and Refresh Rate

Look for providers that refresh contact data at least monthly, daily or real-time updates are the gold standard. Stale records drive up bounce rates and waste rep time on contacts who've changed roles.

Two things decide whether a refresh rate is real or marketing copy.

2. Compliance With GDPR & CCPA

Navigating global data privacy laws is a must for modern businesses, especially in regulated markets like the EU. Ensuring GDPR and CCPA compliance helps protect your brand's reputation and builds trust with prospects.

Three questions tell you whether a provider's compliance claim holds up.

3. Integration With CRM and Workflows

Seamless integration with your CRM keeps vital information at your team's fingertips. When data flows effortlessly across platforms, your sales and marketing operations become far more efficient.

The detail below is what separates a usable integration from a brittle one.

4. Available Segmentation Filters

Precise targeting begins with having the right filters to isolate your ideal prospects. Better segmentation means more personalized interactions and improved conversion rates.

5. Customer Support and Data Customization

A responsive support team can make all the difference in swiftly resolving any platform issues.

Data customization goes hand in hand with strong support, allowing you to shape the tool around your specific business needs.

Support and customisation decide how well a tool survives contact with your workflow.

Types of B2B Data Explained

Not all B2B data is the same. Providers specialize in different categories, and what you need depends on whether you're building a cold-outreach list, researching accounts, or timing your pitch.

Contact data gives you email addresses, direct dials, and LinkedIn URLs. This is table-stakes. Every provider in this guide offers it; the difference is coverage and accuracy.

Firmographic data describes the company: revenue, employee count, location, industry. Use it to filter out accounts that are too small, too enterprise, or outside your vertical.

Technographic data identifies the specific software, platforms, and tools a company currently uses, such as Salesforce as their CRM or AWS as their cloud provider, enabling sellers to target accounts by tech stack.

If you sell to Salesforce users or HubSpot shops, this narrows your list fast. ZoomInfo and BuiltWith lead here.

Intent data is behavioral signal data, content downloads, keyword searches, competitor page visits, that indicates a company is actively researching a purchase in your category.

It flags companies researching topics related to your product, think "downloaded a whitepaper on API security" or "visited five competitor pricing pages this month." Bombora, 6sense, and ZoomInfo Intent specialize in this.

It's not prospecting data; it's timing data.

Job-posting and event data surfaces hiring signals (new VP Sales = potential budget) and trigger events (funding round, office move).

Apollo and Crunchbase surface some of this; dedicated signal providers like Common Room go deeper.

Match your provider to the data type you actually need. If you're doing cold outreach, contact + firmographic filters are enough. If you're running ABM, add intent.

If you're selling dev tools, technographic filters save you hours.

How to Evaluate Intent Data Providers

To evaluate an intent data provider, request a sample report, confirm signal types (first-party vs. third-party), and verify it can push signals into your CRM.

Providers that only surface data in a separate dashboard rarely get used.

Intent data tells you when to reach out, not just who. A company visiting competitor pricing pages, downloading category whitepapers, or searching for "best [your solution] alternatives" is warmer than a cold lead.

What B2B intent data actually captures:
Content consumption (whitepapers, webinars), web activity (category keyword searches), engagement spikes (job postings for roles that use your product), and third-party signals aggregated across publisher networks.

Pick the network that matches how you actually buy.

Make sure the provider can push intent spikes into your CRM or outreach tool, intent data that lives in a separate dashboard gets ignored.

Intent works best when layered onto an existing ICP filter. Don't buy intent alone and hope it replaces list-building. Use it to prioritize the list you already have.

B2B Data Subscription Models: How Pricing Works

B2B data providers charge in three ways: annual seat licenses, credit-based plans, or API subscriptions. The model shapes how much you pay and how fast you'll burn through your budget.

Annual seat licenses

You pay per user, per year. ZoomInfo, Cognism, and Lusha all use this model. Each rep gets unlimited searches and exports within their territory or role limits.

Best for: Teams with predictable headcount and high per-rep usage. If your SDRs export 200+ contacts per month, unlimited seats beat pay-per-record.

Watch out for: Minimum seat commitments. Most enterprise contracts start at 5–10 seats, so a solo founder can't buy just one. Auto-renewal clauses also lock you in for 12–24 months.

Credit-based plans

You buy a monthly or annual bucket of credits. Each export costs 1–5 credits depending on data type (email = 1, mobile = 3, intent signal = 5).

Apollo, Adapt.io, and Kaspr all use credits.

Best for: Small teams or variable usage patterns. If you only prospect in Q1 and Q3, you're not paying for seats you don't use.

Watch out for: Credit expiration. Most providers reset unused credits monthly, so a 500-credit plan becomes expensive if you only use 200.

Also, phone numbers cost 3–5× more than emails, which drains budgets fast.

API subscriptions

You pay for API call volume or per-record enrichment. People Data Labs, Coresignal, and Clearbit charge this way. There's no UI, you're piping data into your own systems.

Best for: RevOps teams enriching CRM records in bulk, product teams building features on top of B2B data, or data teams training ML models.

Watch out for: Engineering dependency. If you don't have a developer to write the API calls and handle rate limits, you can't use the data.

Also, most API providers bill overage at 2–3× the base rate once you exceed your monthly quota.

How to choose

Most teams outgrow credits around 5 seats. At that point, the math tilts toward annual licenses, but only if every seat will actually use the data.
