12 Best Data Enrichment Tools for B2B in 2025 (Free + Paid)

We've been in the B2B data space for years now. We've tested dozens of data enrichment tools, burned through thousands of dollars in subscriptions, and learned the hard way that most platforms overpromise and underdeliver when it comes to finding accurate contact information.

Here's the thing: no single data vendor has a 100% enrichment rate. Not even close. The best ones hover around 40-60% for emails and even lower for mobile phone numbers.

That's why we built FullEnrich around waterfall enrichment, and it's also why we've become obsessed with understanding what each tool on the market actually does well.

We'll be honest about our own limitations too.

The goal is to help you pick the right data enrichment solution for your specific needs, whether that's enriching your CRM data, finding verified emails for cold outreach, or getting mobile phone numbers for your sales team.

Let's dig into the best data enrichment software of 2026.

• Category: Waterfall Enrichment Platform

• Best for: Maximum match rates across multiple data sources

• Ease of use: Beginner

• Pricing: Free trial (50 credits), paid plans start at $29/month

Yes, we're putting ourselves first, but hear us out. FullEnrich was built to solve the fundamental problem with B2B data enrichment: no single vendor has complete coverage.

We aggregate 15+ premium data providers including sources like Apollo, Hunter, Datagma, ContactOut, and others.

When you enrich data, our system cascades through each provider until it finds verified contact information. If the first source doesn't have the email, we try the second, then the third, and so on.

This waterfall enrichment technology consistently achieves 65-85% match rates compared to 25-40% from single-source tools.

How FullEnrich works

• Upload a CSV or connect via API with your prospects' names and companies. Our algorithm selects the best data sources based on the prospect's geographic location and industry.

• For US contacts, certain providers perform better. For EMEA or APAC, using different third-party data providers excel. We handle the routing automatically.

• In the data enrichment process every email goes through triple verification before you're charged credits, keeping bounce rates under 2%.

• Best for: Large sales teams needing comprehensive B2B data

• Ease of use: Intermediate to Advanced

• Pricing: Starts at approximately $15,000/year (contact sales)

ZoomInfo is the 800-pound gorilla in the B2B data space. They've been around since 2000 and have built one of the largest databases of business contacts and company information. If you work in B2B sales, you've almost certainly heard of them.

The platform goes way beyond simple enrichment features. You get intent signals showing when companies are researching solutions like yours, technographic data revealing their tech stack, org charts, department budgets, and real-time alerts for funding rounds and leadership changes.

It's a proper sales companion with powerful sales intelligence automation tools. 

How ZoomInfo works

• ZoomInfo combines data from multiple sources including web scraping, public records, and community-contributed information.

• Their SalesOS product lets you search their database with 200+ filters, export contacts to your CRM, and integrate with your sales engagement tools like Salesforce and HubSpot.

The platform uses a credit-based system where more detailed information (like technographics and org charts) costs more credits than basic contact info.

Who is ZoomInfo for?

• Enterprise sales and marketing teams with substantial budgets.

• Companies doing account-based marketing who need deep firmographic and intent data.

•  Organizations that want an all-in-one sales intelligence and sales engagement platform.

For teams that want to consolidate their tech stack in one place, Apollo is compelling.

They claim over 275 million contacts with 70+ data points per profile. The free plan is genuinely useful, making it a great starting point for teams testing the waters with sales intelligence tools.

However, many teams report accuracy gaps for lead data.

How Apollo works

• Build contact lists, enrich your existing CRM data, and launch automated email sequences directly from the platform.

• Category: B2B Sales Intelligence with Compliance Focus

• Best for: Teams targeting European markets or needing GDPR-compliant data

• Ease of use: Intermediate

• Pricing: Custom pricing (contact sales)

Cognism has carved out a strong niche as the go-to B2B data provider for European markets. While US-focused tools often struggle with EMEA data quality, Cognism has invested heavily in verified, compliant contact information for European prospects.

Their Diamond Data feature provides phone-verified mobile numbers, meaning a human has actually called to confirm the number is correct.

For teams doing cold calling, this dramatically improves connect rates.

However data available in the US is lacking depth. 

How Cognism works

• You can search for contacts, build lists, and export to your CRM.

• Their data includes direct dials, verified emails, and intent data powered by Bombora.

Who is Cognism for?

• Sales teams targeting European markets where GDPR compliance matters.

• Organizations that rely on phone outreach and need verified direct dials.

• Companies expanding internationally who need consistent data quality across europe.

Pricing plans

Which Data Enrichment Tool Should You Choose?

After testing all these tools, here's our honest take on who should use what:

• Choose FullEnrich if: You want the highest possible match rates without managing multiple subscriptions. Our waterfall enrichment across 15+ providers consistently outperforms single-source tools. Ideal for teams doing high-volume outreach who can't afford incomplete data.

• Choose ZoomInfo if: You're an enterprise with budget for comprehensive sales intelligence including intent signals, technographics, and deep integrations. Best for large, mature sales organizations.

• Choose Apollo.io if: You want an all-in-one platform combining data, outreach, and CRM. Great for startups and SMBs who don't want to manage multiple tools.

• Choose Cognism if: You're targeting European markets and need GDPR-compliant data with verified mobile numbers. The Diamond Data feature is worth it for teams relying on cold calling.

• Choose Hunter.io or Lusha if: You're on a budget and primarily need email addresses. Both offer generous free plans to get started.

• Choose Clearbit if: You're a HubSpot customer who needs real-time enrichment for forms and lead routing.

The reality is that building your ideal customer profile (ICP) and reaching those prospects requires accurate data. Bad data means wasted time, damaged domain reputation, and missed sales pipeline opportunities.

Whatever tool you choose, the key is testing data quality before committing to annual contracts. Most platforms offer free trials, so use them. Upload a sample of your target accounts and measure actual match rates and deliverability, not just what the marketing pages promise.

If you want to see how waterfall enrichment compares to your current approach, try FullEnrich free with 50 credits. No credit card required, no sales call needed. See the match rates for yourself and make an informed decision.

Happy prospecting.
