How Does ZoomInfo Get Their Data? Can You Rely on ZoomInfo's database?

Have you ever wondered where ZoomInfo gets all those company contacts and profiles?

Unlike LinkedIn Sales Navigator and other lead generation sites, ZoomInfo builds its database differently. Using sophisticated methods, it gathers, verifies, and maintains the business information you need daily.

When sales prospecting automation tools like ZoomInfo lack everything you need, you'll probably rely on contact data enrichment platforms to fill the gaps.

By understanding how ZoomInfo collects data, you can decide which business development tools to use to get the most complete view of your customers.

AI highlights

• Understand ZoomInfo's Data Collection: ZoomInfo's massive B2B database is built through web crawling, data partnerships, user contributions via Community Edition, and AI-powered verification systems. To maximize results, identify your top 20 target accounts and search for them specifically rather than browsing general categories.

• Consider data privacy implications: Before implementing ZoomInfo, develop a clear data-handling policy for your team. Document how you'll use, store, and eventually dispose of prospect data in compliance with regulations like GDPR and CCPA to avoid potential legal issues.

• Evaluate Alternatives Based on Your Needs: Instead of trying multiple options, select platforms based on your specific sales motion—choose PhantomBuster for engagement-based outreach, Apollo.io when budget constraints exist, or Clay when you need to combine data from multiple specialized sources into unified prospect profiles.

What is Zoominfo?

ZoomInfo empowers sales and marketing teams with access to company and contact information through its B2B intelligence platform. You can use it to identify decision-makers, generate leads, and create targeted outreach campaigns.

ZoomInfo is good for prospecting complex enterprise accounts with multiple stakeholders.

How does ZoomInfo get their data?

ZoomInfo collects its business information through several key methods, each contributing to its extensive database of contact details, company profiles, and market trends.

Here's a summary of how ZoomInfo collects business data for its massive intelligence database:

Web crawling

ZoomInfo uses web crawlers to continuously scan public information sources, including company websites, professional profiles, news articles, financial filings, and job postings.

The crawlers extract sensitive personal data from these sources, like contact information, company statistics, leadership structures, and technology implementations.

ZoomInfo's crawlers are particularly effective at finding the digital footprints of senior decision-makers who may not maintain active LinkedIn profiles but appear in press releases and corporate filings.

Data partnerships

ZoomInfo forms strategic partnerships with specialized data providers and business directories to significantly enhance the database's depth and breadth.

These collaborations give you access to industry-specific datasets, improve information verification processes, and expand geographic coverage beyond what web crawling alone could achieve.

These partnerships are the secret behind ZoomInfo's superior coverage of mid-market companies that often go unnoticed by other platforms.

User contributions

The Community Edition program represents ZoomInfo's innovative approach to data collection. Members share their professional contacts in exchange for platform access.

When you install the browser extension, it analyzes email signatures, captures business card information, and identifies professional relationships, creating a continuously expanding network of verified contacts.

Artificial intelligence and machine learning

ZoomInfo employs advanced AI technology as the quality control system for the entire database.

AI systems identify duplicate entries, fill in information gaps based on similar data patterns elsewhere, detect outdated records, and create connections between related data points, creating a more complete and accurate picture of companies and contacts.

What kind of data can you get from ZoomInfo?

Access contact info (email, phone, direct dial), company information (revenue, employees, industry), organizational structures, technology stacks, buying intent signals, office locations, and professional social profiles.

You can leverage this data for prospecting, and your sales and marketing professionals teams can use it for targeted campaigns, often integrating it with automated sales pipeline systems.

Is the information provided by ZoomInfo reliable?

ZoomInfo's data reliability is strong, especially for larger organizations and U.S.-based contacts. To maintain data quality, ZoomInfo regularly refreshes its database through multiple verification methods.

Jon O., a Vice President at a mid-market company, describes ZoomInfo as "a very powerful and reliable tool" for keeping Salesforce data accurate and current. He emphasizes how it helps segment, organize, and update records efficiently.

Marketing Campaign Manager Anna L. values ZoomInfo's CRM integration for providing "accurate and reliable contact information," helping her team enhance outreach effectiveness with "more accurate data for campaigns."

You'll want to supplement with other sources when targeting startups under two years old, where data quality tends to drop significantly.

Does ZoomInfo align with privacy regulations in the US and around the world?

ZoomInfo ensures compliance with major privacy regulations, including GDPR and CCPA. It provides opt-out options through its privacy center and maintains industry certifications like SOC 2 Type II.

The company collects only business information that is publicly available or user-contributed, positioning itself as a B2B data provider rather than a consumer data broker.
