What Is a B2B Data Provider?

A B2B data provider is a company that collects, verifies, and sells business information to other companies. This data typically includes:

• Contact data: Email addresses, phone numbers, direct dials, and mobile numbers
• Firmographic data: Company size, revenue, industry, location, and founding year
• Technographic data: The software and tools a company uses
• Intent data: Signals that indicate a company is actively researching or ready to buy
• Job data: Open positions, hiring trends, and organizational changes

B2B data powers several critical business functions:

• Sales prospecting: Finding and contacting decision-makers
• Lead generation: Building targeted lists for outreach campaigns
• Account-based marketing (ABM): Targeting specific high-value accounts
• CRM enrichment: Keeping your database accurate and complete
• Market research: Understanding industry trends and competitor activity
• Risk assessment: Evaluating potential partners and suppliers

The data comes from various sources, including public records, web scraping, third-party partnerships, and proprietary collection methods. For a deeper dive into how companies gather this information, check out our guide on data sourcing.

Why Data Quality Matters More Than Quantity

Here’s something most vendors won’t tell you: B2B contact data decays at roughly 2.1% per month. That adds up to 22.5% annually, according to HubSpot research. Some estimates put annual decay as high as 70%.

This happens because people change jobs, companies get acquired, phone numbers change, and email addresses become invalid. A database with 100 million contacts sounds impressive until you realize a significant portion might be outdated.

The takeaway? Focus on data freshness and verification processes, not just database size.

Types of B2B Data Explained

Before comparing providers, it helps to understand what you’re actually buying:

Contact Data

Names, job titles, email addresses, phone numbers (including direct dials and mobile), and social media profiles of individual professionals. This is the bread and butter of sales prospecting.

Firmographic Data

Company-level information like industry classification, employee count, annual revenue, headquarters location, and founding year. Think of it as demographics for businesses.

Technographic Data

Information about what technology a company uses. Knowing that a prospect runs Salesforce, HubSpot, or a specific ERP system helps tailor your pitch and identify compatibility.

Intent Data

Behavioral signals that suggest a company is actively researching solutions like yours. This might include visiting competitor websites, downloading whitepapers on relevant topics, or searching for specific keywords. Intent data helps prioritize accounts that are ready to buy.

Job Posting Data

Current open positions at target companies. Hiring patterns reveal budget allocation, growth areas, and potential needs. A company hiring multiple SDRs probably needs sales tools.

How to Choose the Best B2B Data Provider

Not all data vendors are created equal. Here’s what to evaluate:

Data Quality and Accuracy

Look for providers that disclose their accuracy rates and verification methods. Some vendors verify emails in real-time, while others rely on periodic batch updates. Ask about bounce rates and invalid phone number percentages.

Coverage and Depth

Consider both geographic coverage and the depth of information per record. A provider might have strong US data but limited European coverage. Similarly, some excel at enterprise contacts but miss SMBs.

Data Freshness

How often is the database updated? Real-time verification beats monthly or quarterly refreshes. Ask specifically about their data refresh frequency and decay management.

Compliance

GDPR, CCPA, and other privacy regulations matter. Vendors should be transparent about how they source data and maintain compliance. Some providers check against Do Not Call (DNC) lists, which is critical if you’re doing phone outreach.

Integration Options

Can the data flow directly into your CRM (Salesforce, HubSpot, Pipedrive)? Look for native integrations, APIs, and export formats that match your workflow.

Pricing Model

Some charge per contact or credit, others offer unlimited access within tiers. Credit-based systems can get expensive fast if you need high volume. Understand what “credits” actually mean for each provider.

Support and Onboarding

Access to customer support, especially when you’re getting started, can save significant time. Some providers include dedicated account managers; others rely on self-service.

Free Trial or Sample Data

Testing before buying is ideal. Many providers offer free trials, sample datasets, or limited free tiers.

Common Mistakes When Buying B2B Data

1. Focusing Only on Database Size

A vendor claiming “500 million contacts” sounds impressive, but size without accuracy wastes money. Ask about verification methods and decay rates.

2. Ignoring Integration Needs

If data doesn’t flow into your CRM or outreach tools, you’ll spend hours on manual imports. Check native integrations before buying.

3. Underestimating Credit Costs

Credit-based pricing can surprise you. Calculate your actual usage patterns before committing. Some vendors charge separately for emails and phone numbers.

4. Skipping Compliance Checks

Using non-compliant data can result in fines and reputation damage. Verify GDPR and CCPA compliance, especially for European outreach.

5. Not Testing First

Most reputable providers offer trials or samples. Use them. Test data quality against your ICP before signing contracts.

Frequently Asked Questions

What is the difference between a B2B data provider and a sales intelligence platform?

A B2B data provider primarily sells contact and company information. A sales intelligence platform combines that data with additional tools like email sequencing, calling, intent signals, and CRM integration. Some vendors (like Apollo.io) offer both. Others (like Bright Data) focus specifically on data.

How do B2B data providers collect their data?

Methods vary by provider but typically include:

• Web scraping and crawling public sources
• Partnerships with third-party data vendors
• User contributions (some platforms)
• Public records and filings
• Email and phone verification services

How often should B2B data be updated?

Given that contact data decays at roughly 22.5% per year, look for providers that refresh data at least monthly. Real-time verification at the point of access is ideal for phone numbers and emails.

Is using B2B data legal?

Yes, when sourced and used in compliance with applicable regulations. Key considerations:

• GDPR (Europe): Requires legitimate interest or consent for processing personal data
• CCPA (California): Gives consumers rights over their data; business data generally exempt
• CAN-SPAM (US): Governs commercial email; doesn’t restrict data purchase itself

Reputable vendors handle compliance on their end, but you’re responsible for how you use the data.

What’s the best B2B data provider for small businesses?

For budget-conscious teams, Apollo.io, Lusha, and UpLead offer the best combination of usability, free tiers, and transparent pricing. Kaspr works well if you’re focused on LinkedIn prospecting.

How do I evaluate data quality before purchasing?

Request sample data matching your Ideal Customer Profile (ICP). Test email deliverability and phone connectivity. Ask vendors about their accuracy rates, verification processes, and data freshness metrics.

What’s intent data and is it worth paying for?

Intent data identifies companies showing buying signals, like researching topics related to your product. It’s valuable for prioritizing outreach but typically comes at premium pricing. It’s most useful for ABM strategies where you need to identify ready-to-buy accounts.

Conclusion

Choosing a B2B data provider depends on your specific needs: budget, target geography, integration requirements, and how you’ll use the data.

For organizations needing large-scale, customizable datasets from multiple business platforms, Bright Data offers the most flexibility and global coverage with 1B+ business records.

Enterprise teams focused on North American sales will find ZoomInfo comprehensive. SMBs and startups often get the best value from Apollo.io. European-focused teams should prioritize Cognism, Kaspr, or Dealfront for compliance and regional coverage.

Beyond B2B data, Bright Data’s marketplace includes:

• Social Media Datasets: Facebook, Instagram, YouTube, Reddit
• Ecommerce Datasets: Amazon, Walmart, Target, and more
• Financial Datasets: Yahoo Finance, MarketWatch, Investopedia
• Real Estate Datasets: Zillow, MLS, and others

Whatever provider you choose, test before you commit, verify compliance, and remember that data quality beats database size every time.
