List of Data Providers: 12 Tools Ranked With Real Pricing

The Only List of Data Providers That Includes Real Pricing

B2B contact data decays at 2.1% per month. That's nearly a quarter of your database going stale every year. Over 25% of organizations lose more than $5M annually from poor data quality, which means your choice of data provider isn't a software decision - it's a revenue decision. And yet most data vendors won't tell you what anything costs until you've sat through a 45-minute demo and handed over your work email.

We've spent years testing these tools across real outbound campaigns, and this list reflects what we've actually seen, not what vendor marketing pages claim. The focus here is B2B contact and company data - the stuff sales and marketing teams use to find prospects. If you need financial data (PitchBook), consumer data (Experian), or data infrastructure (Snowflake Marketplace), that's a different conversation entirely.

Every tool has a real price. No "contact sales" cop-outs.

All 12 Data Providers Ranked

Prospeo

Use this if you care about email deliverability above everything else and don't want to negotiate an annual contract.

Prospeo's database covers 300M+ professional profiles drawn from 800M+ collected records, with 143M+ verified emails and 125M+ verified mobile numbers. The 98% email accuracy comes from a proprietary 5-step verification process - catch-all handling, spam-trap removal, honeypot filtering. Mobile numbers carry a 30% pickup rate; a Salesfinity benchmark across 9 phone data providers found accuracy ranging from 63% to 91% on 307 verified contacts, and Prospeo's verified mobiles sit at the top of that range.

The Chrome extension - 40K+ users - lets you pull verified contacts from any website in one click. CRM enrichment runs at a 92% API match rate, returning 50+ data points per contact. Search filters cover buyer intent across 15,000 Bombora topics, technographics, job change signals, and headcount growth. Pricing sits at roughly $0.01 per email with a free tier. No contracts, no sales calls required.

Real-world proof: Snyk's team of 50 AEs cut bounce rate from 35-40% to under 5%, AE-sourced pipeline increased 180%, and they generated 200+ new opportunities per month.

Apollo.io

Apollo's 275M+ contact database is solid, but the built-in email sequencing is the real differentiator. It's the only tool on this list where you can find a lead, enrich it, and email it without leaving the platform. G2 reviewers love it: 4.8/5 across 7,500+ reviews. Pricing is transparent - Free tier, Basic at $49/user/mo, Professional at $79/user/mo, Organization at $119/user/mo.

Here's the thing: Apollo's email accuracy lags behind dedicated verification platforms. We've seen bounce rates in the 15-20% range on Apollo-sourced lists, which is fine for high-volume outbound but painful if you're protecting a new domain. G2 reviewers consistently flag that advanced features like intent data and AI scoring are locked behind higher tiers, frustrating smaller teams who thought they were getting the full package.

Best for SMBs that want prospecting, sequencing, and a CRM in one platform. Skip this if email deliverability is your top priority or you're running outbound for clients where domain reputation is non-negotiable.

ZoomInfo

Everyone's first question about ZoomInfo: is it worth ~$15K-$45K+/year?

For enterprise orgs with 50+ seats running account-based selling, intent, and outbound from a single platform - yes. The database is deep, especially for US contacts, and the workflow breadth across intent, chat, engage, and enrich modules is unmatched. G2 gives it 4.4/5 across 8,600+ reviews. More reviews than anyone else, but a lower score. That tells you something.

A common complaint on r/sales is paying for modules you don't use. For a 10-person team, ZoomInfo is a semi-truck to deliver groceries. Most teams under 50 seats are overpaying, and the annual contracts with auto-renewal clauses make it hard to walk away once you've signed.

Let's be honest: ZoomInfo is still the best all-in-one enterprise platform. But most teams don't need all-in-one. If your average deal size is under $15K or your team is under 50 reps, you'll get 80% of the value from other tools at 20% of the cost.

Cognism

Diamond Data - Cognism's human-verified phone numbers - is the feature that justifies the price tag. If you're selling into EMEA and need GDPR-compliant data with verified mobiles, nothing else comes close right now.

Pricing uses a platform fee plus per-user model: the Grow tier runs ~$15K/year platform plus ~$1,500/user/year, so roughly $22,500/year for five users. The Elevate tier with Diamond Data and Bombora intent jumps to ~$37,500/year for five users. Budget for onboarding fees of $2,000-$5,000 and potential API overages of $5,000-$15,000/year. On the bright side, discounts of 28-52% are common through negotiation - push hard on renewal pricing.

Watch the fine print: 60-day auto-renewal windows, 10-15% annual increases, and "unlimited" access that often lands around ~2,000 records/user/month via fair-use policies.

Best for EMEA-focused teams. Skip this if you're US-only or need month-to-month pricing.

Lusha

Use this if you're an individual rep who needs quick contact lookups without a platform commitment. Free tier gives you 50 emails and 5 phone numbers per month. Paid plans start at $59/user/mo. Credits don't roll over, which stings if your prospecting is uneven. Skip this if you need bulk exports or team-wide data operations.

UpLead

UpLead verifies emails at the point of export, which means you're not paying for bad data. In our testing, this real-time verification eliminated nearly all bounces - a G2 4.7/5 rating across 780 enthusiastic reviewers backs that up. Essentials runs $99/mo, Plus at $199/mo. The database isn't as deep as Apollo or ZoomInfo for niche verticals, but the data you do get tends to be clean. Skip this if you need 275M+ contacts or deep intent data.

Kaspr

A lightweight Lusha alternative with better European coverage. Free plan available, paid from $49/user/mo. Good for quick phone number lookups from professional profiles when your team is based in Europe. Skip this if you need a full prospecting database or US-focused data.

Clearbit (Breeze Intelligence)

Now HubSpot-owned and rebranded as Breeze Intelligence, credit packs run $30-$700/month for 100 to 10,000 credits. The real-time enrichment is excellent for form shortening and lead scoring within HubSpot. Skip this if you're not on HubSpot - the value proposition collapses without the native integration.

Hunter.io

Use this if you need to find a specific person's email address and nothing else. Free tier gives you 50 emails/month, paid plans from $34/mo. Hunter indexes 300M+ email addresses and is known for domain search. It's a surgical tool, not a full database. Skip this if you need phone numbers, company data, or intent signals.

Dealfront

Selling into DACH markets? Dealfront offers compliance-first European company data with strong account identification. Custom pricing typically runs $1,000-$3,000/mo for small teams, with a free trial available. Skip this if your target market is primarily North America.

6sense

This is a Forrester Wave Leader for B2B intent data, and the pricing reflects it: $50K-$300K+/year. Here's the reality check - 91% of B2B marketers use intent data, but only 24% report exceptional ROI. Without a dedicated ops team to operationalize the signals, you're buying an expensive dashboard that nobody acts on. Skip this if you have fewer than 50 seats or no dedicated RevOps function.

Demandbase

Enterprise pricing typically runs $30K-$100K+/year. Also a Forrester Wave Leader for intent data. Demandbase edges out 6sense on advertising capabilities but trails on pure intent signal depth. Skip this if you don't have a mature ABM program already in place.

How to Evaluate Any Data Vendor

Email accuracy matters more than database size. A Cleanlist benchmark of 1,000 B2B records found single-source databases hit just 62% email accuracy versus 98% for waterfall enrichment. The gap between "good enough" and "actually good" is enormous for deliverability - and it's the difference between landing in inboxes and getting your domain blacklisted.

Data refresh cycle is the single biggest predictor of quality over time. At 2.1% monthly decay, a database refreshed every six weeks is already 3-4% stale by the time you use it. Ask your provider how often they update. If they can't answer, that's your answer.

Multi-source aggregation is worth paying attention to. Vendors that pull from multiple sources - web scraping, partnerships, public filings, user contributions - tend to deliver higher match rates and more complete records than those relying on a single collection method.

Pricing transparency signals how a vendor treats customers. If a company makes you sit through a demo to learn what it costs, factor in the time you're wasting as part of the price. We've watched teams burn two weeks on ZoomInfo evaluations before learning the budget didn't fit.

Compliance isn't optional. GDPR and CCPA violations carry real fines. Any provider without clear opt-out enforcement and DPA availability is a liability, full stop.

Integrations determine whether data actually reaches your workflow. Check native connections to your CRM and sequencer before you trial - the best data in the world is useless if it's trapped in a separate tab.

Choosing the Right Provider for Your Team Size

FAQ

What's the difference between a data provider and an enrichment tool?

Data providers sell net-new contact records for outbound prospecting. Enrichment tools fill gaps in existing CRM data - missing emails, outdated titles, incomplete firmographics. Most modern platforms do both. Prospeo, for example, offers a prospecting database alongside CRM enrichment at a 92% API match rate.

How often should B2B contact data be refreshed?

At 2.1% monthly decay, roughly a quarter of your database goes stale annually. Top-tier vendors refresh on a 7-day cycle; the industry average sits around six weeks. Check your provider's refresh cadence before signing - it's the single biggest predictor of data quality over time.

Are "unlimited" data plans really unlimited?

Almost never. Cognism's "unlimited" access is constrained by fair-use policies at around 2,000 records per user per month, and exports consume additional credits. Always ask about export limits, API caps, and fair-use thresholds before committing. The Reddit consensus on r/sales is that "unlimited" in B2B data means "unlimited until you actually try to use it."

Which data provider has the highest email accuracy?

Independent benchmarks show accuracy ranging from 62% to 98% depending on methodology. Waterfall enrichment - running leads through multiple verification steps - consistently outperforms single-source lookups. Prospeo's proprietary 5-step verification delivers 98% accuracy; most competitors land between 85-90%.

Can I use multiple B2B data vendors together?

Yes, and many teams should. Waterfall enrichment, where you run leads through multiple sources sequentially, can boost match rates from 62% to 98% per the Cleanlist benchmark. A common setup we've seen work well is pairing a primary provider for initial prospecting with a secondary source for verification and gap-filling, effectively building a database that no single vendor could deliver alone.
