Your outreach is only as good as your data. We evaluated 10 leading B2B data providers across accuracy, coverage, pricing, and compliance so you can choose the right one for your team.
TL;DR
The best B2B data providers in 2026 are Lusha (best overall for verified contacts and buying signals), ZoomInfo (best for large enterprise US outbound), and Apollo.io (best all-in-one value for SMBs). We compared 10 tools below on accuracy, pricing, and fit.
What is B2B data?
B2B data is structured information about businesses and their employees, including verified contact details, company firmographics, technographics, and behavioral signals, that revenue teams use to identify, reach, and prioritize prospects. According to a widely cited industry benchmark, B2B contact data decays at roughly 30% per year as professionals change roles and companies evolve, making a reliable, continuously updated data provider essential for any outbound or account-based program.
- Contact data: Verified emails, direct phone numbers, and LinkedIn profiles for decision-makers across roles and industries
- Company data: Firmographics (size, revenue, industry, location) and technographics (tech stack in use) to qualify accounts before outreach
- Buying signals: Real-world events, including job changes, funding rounds, technology switches, and hiring trends, that indicate when an account may be in the market
- Enrichment: Automated workflows that append missing data to CRM records, forms, and spreadsheets. See how data enrichment works to keep the GTM stack accurate without manual effort
- Primary users: SDRs building outbound lists, RevOps teams maintaining CRM hygiene, marketing ops running ABM campaigns, and AEs researching target accounts before meetings
Below, we evaluated 10 B2B data providers on the criteria that matter most: data accuracy, global coverage, signal quality, compliance posture, integration depth, and pricing transparency.
How we evaluated
We assessed each provider using a consistent framework across six dimensions. Here is what we looked at:
- Data accuracy: Email deliverability rates, phone number accuracy, and how providers verify and refresh their data
- Database coverage: Total contacts, global geographic reach, and depth in key markets like the US, EMEA, and APAC
- Signal quality: Whether the platform surfaces real-time buying signals beyond static contact data
- Compliance: GDPR, CCPA, SOC 2, and other data protection certifications relevant to B2B outreach
- Integrations: Native connections to CRMs, sales engagement platforms, APIs, and automation tools
- Pricing and flexibility: Transparent pricing, free plan availability, and contract terms

1. Lusha
Lusha is a B2B data provider and sales intelligence platform built for revenue teams that need verified contact and company data, real-time buying signals, and seamless workflow integrations. With 300M+ contacts, 30M+ company profiles, and a crowdsourced data community that continuously verifies and refreshes records, Lusha delivers 98% email accuracy and 86% phone accuracy, two of the highest verified rates in the category. More than 1M users across 223,000+ organizations rely on it for prospecting, CRM enrichment, and AI-powered account prioritization.
What separates Lusha from pure contact databases is the signal layer. Job changes, funding rounds, technographic shifts, and intent signals are built in, not sold as expensive add-ons. That combination lets GTM teams find the right contact and act at the right moment, without stitching together multiple tools. The Chrome extension surfaces data directly on LinkedIn and company websites, and API and MCP connectivity supports AI agents and automation platforms natively.
One team that switched to Lusha was Revium, which had been struggling with poor data quality from a previous provider. After moving to Lusha, they achieved 95% email deliverability and a 72% phone contact rate, saving $85,000 annually.
Lusha’s compliance posture is unusually broad: GDPR, CCPA, SOC 2 Type 2, ISO 27001, ISO 27017, ISO 27701, ISO 31700, and ISO 42001, with a public Trust Center and opt-out mechanism. For teams selling into regulated industries or EMEA markets, that depth matters.
Pros
- Industry-leading data accuracy: 98% email and 86% phone, verified by community and AI
- Real-time buying signals built in, including job changes, funding, technographics, and intent
- Broadest compliance posture in the category, covering ISO 42001 for AI governance
- Free plan with 40 credits per month, no credit card required
- MCP and API support for AI agent and automation workflows
- Chrome extension works on LinkedIn, Gmail, and company websites
Cons
- EMEA phone coverage is growing but not yet at Cognism’s Diamond Data level for UK and Germany
- AI features like ICP-based recommendations are still maturing compared to ZoomInfo Copilot
- Fewer native integrations than enterprise-tier platforms
Pricing
Free plan: 40 credits/month, no credit card required. Paid plans start at $37/mo on annual billing (Starter, 400 credits, 1 seat). Professional is $52/mo annual (600 credits, 2 seats). Premium is $299/mo annual (3,400 credits, 5 seats, with credit rollover). Month-to-month pricing also available.
What users say
“It saves me so much time since people on LinkedIn often take 3 to 5 days to reply, but with Lusha, I can contact them instantly.”
Best for
SMBs and mid-market revenue teams that need accurate B2B contact data with real-time buying signals, without enterprise-level pricing or long-term contract commitments. Particularly strong for teams prospecting in North America and growing into EMEA, and for RevOps teams building automated B2B data enrichment workflows.
2. ZoomInfo
ZoomInfo is the largest B2B database in the US, with 260M+ contacts and deep Bombora-powered intent data. For enterprise sales teams running high-volume outbound in North America, it remains the benchmark: comprehensive firmographic and technographic coverage, 50+ native integrations, AI Copilot for prospect recommendations and email drafting, and conversation intelligence baked into the platform. If you have the budget and dedicated admin to manage it, ZoomInfo can anchor a sophisticated GTM program.
The trade-offs are real. Pricing starts around $15,000 per year and typically runs $20,000 to $50,000 for most teams, with annual-only contracts and aggressive renewal terms. EMEA and APAC data quality drops noticeably compared to US coverage. And onboarding is complex enough that most teams need dedicated RevOps support just to configure it properly.
Pros
- Largest US contact database, with the deepest intent data through Bombora integration
- 50+ native integrations with CRMs, engagement platforms, and marketing automation tools
- AI Copilot for prospect recommendations, email drafting, and conversation intelligence
- Enterprise-grade compliance: GDPR, CCPA, SOC 2, ISO 27001
Cons
- Annual-only contracts starting around $15,000/yr, with limited negotiating flexibility for smaller teams
- EMEA and APAC data quality significantly weaker than US coverage
- Steep learning curve and complex implementation requiring dedicated admin
- Aggressive upsell and renewal practices widely documented on G2
Pricing
Annual contracts only, typically starting around $15,000/yr for small teams and scaling to $50,000+ for enterprise. No self-serve pricing. Demo required to get a quote.
What users say
“The pricing is extremely high and the contract terms are very restrictive. Once you’re in, it’s hard to get out.”
Best for
Large enterprise US outbound teams with dedicated RevOps support, the budget for annual contracts, and a strong North American market focus. For teams evaluating more accessible options, see our full guide to the 10 best ZoomInfo alternatives.
3. Apollo.io
Apollo.io is the most popular all-in-one platform for SMBs and growth-stage teams that want B2B data and outreach in a single subscription. With 275M+ contacts, a built-in email sequencer, LinkedIn outreach, and one of the highest G2 ratings in the category (4.7/5 across 9,000+ reviews), Apollo delivers strong value at an accessible price. The free plan includes 50 email credits per month, and paid plans start at $49/user/month.
The bundled sequencer is both Apollo’s biggest advantage and its biggest limitation. Teams already running Outreach or Salesloft are paying for outreach capability they won’t use. Phone data quality is also a recurring complaint: real-world mobile accuracy runs closer to 55%, noticeably below Apollo’s claimed figures, and support response times on lower-tier plans are slow.
Pros
- Best value all-in-one platform, combining data and email outreach in one subscription
- 275M+ contacts and 73M+ companies, with strong global coverage
- Highest G2 rating in the category: 4.7/5 across 9,000+ reviews
- Free plan available; paid plans start at $49/user/mo
- AI email writer, lookalike search, and ICP recommendations included
Cons
- Phone data accuracy inconsistent; real-world mobile hit rates well below claimed figures
- Customer support slow to respond, especially on entry-tier plans
- Bundled sequencer adds cost if you already run Outreach or Salesloft
- Data freshness lags behind premium verification-first tools
Pricing
Free plan: 50 email credits/month. Paid plans start at $49/user/month on annual billing. Higher tiers unlock phone credits, AI features, and higher export limits.
What users say
“Phone number accuracy leaves a lot to be desired. About half the numbers I try are wrong or outdated.”
Best for
SMBs and growth-stage teams that want a single platform for B2B data, email sequencing, and AI-assisted outreach, especially if they don’t already run a dedicated sales engagement tool. For alternatives with stronger phone accuracy, see the 10 best Apollo.io alternatives.
4. Cognism
Cognism is the leading B2B data provider for EMEA-focused revenue teams. Its Diamond Data program applies human verification to mobile phone numbers in the UK, Germany, and other key European markets, delivering roughly 98% accuracy on those verified numbers. That’s a meaningful differentiator for teams doing phone-first outreach in Europe. Cognism’s compliance posture is also the strongest in the category for GDPR-regulated markets, which matters when selling to regulated buyers across the EU.
Outside EMEA, the value proposition weakens. US and APAC coverage is noticeably thinner than ZoomInfo, and there’s no built-in outreach tool. Pricing starts around $15,000/yr on annual-only contracts, with no self-serve option. For teams without a strong EMEA focus, Cognism’s premium may be hard to justify.
Pros
- Diamond Data: human-verified UK and European mobile numbers with approximately 98% accuracy
- Strongest GDPR compliance positioning in the market, with SOC 2 and CCPA as well
- 400M+ contacts globally, with genuinely strong EMEA depth
- Clean UI that integrates with major CRMs and sales engagement platforms
Cons
- Annual contracts only, starting around $15,000/yr with limited flexibility
- US and APAC data noticeably weaker than EMEA coverage
- No built-in outreach, requiring a separate sequencing tool
- Bombora intent data is an expensive add-on, not included by default
Pricing
Custom pricing only. Annual contracts typically start around $15,000/yr. Trial available on request. No self-serve plan.
What users say
“Their Diamond Data verification for phone numbers is genuinely impressive, with a much better hit rate than ZoomInfo for UK numbers.”
Best for
Mid-market and enterprise teams with a strong EMEA outbound motion that need compliant, phone-verified contacts in the UK and Western Europe. For more flexible pricing options, see our roundup of the best Cognism alternatives.
5. UpLead
UpLead stands out with a 95% email accuracy guarantee backed by an actual credit-back policy: if an email bounces, you get the credit back. It is one of the few B2B data providers that puts a financial commitment behind its accuracy claims. The platform covers 160M+ contacts and 16M+ companies, includes technographic filters, and requires no annual contract. For teams burned by inaccurate data from competitors, the credit-back mechanism alone is worth evaluating.
Pros
- 95% email accuracy guarantee with a credit-back policy for bounces
- No annual contract required, month-to-month flexibility
- Clean, simple UI with a 9/10 G2 ease-of-use score
- Technographic filters to find companies by tech stack
- 4.7/5 G2 rating, among the highest in the category
Cons
- Smaller database than ZoomInfo or Apollo, especially for non-US contacts
- Limited buying signal coverage; no AI-powered account prioritization
- Phone data is weaker than email for direct-dial prospecting
- Basic automation compared to full-platform alternatives
Pricing
Starts at $99/mo with no annual lock-in. A 5-credit free trial is available. Higher tiers unlock more monthly credits and API access.
What users say
“The 95% accuracy guarantee is real. They actually credit you back when emails bounce, which builds trust.”
Best for
SMBs and mid-market teams running email-driven outbound who want a credible accuracy guarantee and the flexibility of month-to-month pricing, without committing to an annual contract.
6. Clearbit (HubSpot Breeze)
Clearbit was acquired by HubSpot in 2023 and is now integrated into HubSpot’s Breeze Intelligence product. For teams already running HubSpot as their CRM, it provides real-time contact and company enrichment directly inside the platform: form shortening, website visitor identification, and buyer intent scoring, all without leaving HubSpot. Data quality is strong for US and North American contacts, and the form shortening feature can meaningfully increase conversion rates on gated content.
Outside of HubSpot, Clearbit essentially has no standalone value. The enrichment is tightly coupled to the HubSpot data model, and pricing assumes you already have a paid HubSpot subscription. If you’re on Salesforce, a different CRM, or any other stack, this tool won’t work for you.
Pros
- Tightest HubSpot-native CRM enrichment available, fully integrated into the platform
- Real-time API enrichment and form shortening to improve inbound conversion rates
- Buyer intent data for identifying high-intent website visitors
- Breeze Copilot AI features available on higher HubSpot tiers
Cons
- Requires a HubSpot subscription to use; no value without it
- International data quality drops significantly outside the US and Canada
- Combined cost (HubSpot subscription plus Breeze add-on) is expensive for smaller teams
- No phone or direct dial data as a primary capability
Pricing
Approximately $75/mo as an add-on, but requires an existing paid HubSpot subscription. Total cost depends on your HubSpot tier.
What users say
“If you’re not on HubSpot, this tool is basically unusable. The whole value prop is tied to the HubSpot ecosystem.”
Best for
HubSpot-native marketing and RevOps teams that want seamless CRM enrichment, form conversion optimization, and buyer intent data without leaving the HubSpot workspace. For teams on Salesforce or other CRMs, a standalone data enrichment provider like Lusha is a better fit.
7. Hunter.io
Hunter.io does one thing extremely well: finding and verifying business email addresses by domain. Enter a company’s website domain and Hunter surfaces all publicly indexed email addresses for that organization, with a confidence score for each result. The tool is built for individual contributors, content marketers, and small teams running targeted outreach at modest scale. The free plan (25 searches/month) covers a surprising amount of ground before you need to upgrade.
Hunter has no phone data, no buying signals, no enrichment workflows, and minimal firmographic coverage. It is purposefully narrow. If you need anything beyond email discovery, you will outgrow it quickly. But for what it does, it’s reliable, affordable, and immediate to use.
Pros
- Domain-based email discovery finds all indexed email addresses at a company in one search
- Confidence scoring helps prioritize high-probability addresses
- 91% claimed email accuracy with real-time verification
- Zero learning curve; immediate value from day one
- Accessible free plan with 25 searches per month
Cons
- Email only: no phone data, no direct dials, no buying signals
- No company firmographic data beyond domain-based email coverage
- Not suited for scaled outbound teams or multi-channel workflows
- Accuracy degrades for less publicly indexed domains and non-English markets
Pricing
Free plan: 25 searches/month. Paid plans start at $34/mo on annual billing for 500 searches/month.
What users say
“Great for finding emails but once you need anything else, phone numbers, signals, you hit a wall.”
Best for
Content marketers, journalists, small sales teams, and individual contributors who need affordable, reliable email discovery for targeted outreach campaigns, and have no need for phone data or broader sales intelligence.
8. Snov.io
Snov.io combines a 500M+ contact database with built-in email and LinkedIn outreach automation at one of the most competitive price points in the market. Email verification happens in real-time, and the platform’s claimed 98%+ accuracy is backed by a continuous verification engine. The integration ecosystem is broad: HubSpot, Pipedrive, Salesforce, Clay, Make, and n8n are all supported natively, making it a strong fit for teams already running automation workflows.
The main limitation is the absence of phone data. Like Hunter.io, Snov.io is email-first, and direct-dial prospecting is not a use case it covers. Signal coverage is also limited compared to tools like Lusha or ZoomInfo.
Pros
- 500M+ contacts with 98%+ email accuracy via real-time verification
- Built-in email and LinkedIn outreach sequences, no separate tool required
- Very affordable entry price at $39/mo with a 50-credit free plan
- Wide integration ecosystem: HubSpot, Pipedrive, Clay, Make, n8n, and more
- 4.6/5 G2 rating with consistently positive ease-of-use feedback
Cons
- No phone or direct dial data
- Limited buying signals compared to ZoomInfo or Lusha
- Enrichment capabilities are narrower than dedicated enrichment platforms
- EMEA phone coverage is not available
Pricing
Free plan: 50 credits/month. Paid plans start at $39/mo. No annual contract required on entry tiers.
What users say
“The email finder is accurate and the drip campaigns save hours of manual work.”
Best for
SMBs and mid-market teams running email-first outbound who want prospecting and sequencing in one affordable platform, particularly teams already using automation tools like Clay, Make, or n8n.
9. Seamless.ai
Seamless.ai uses a real-time search engine model rather than a static database. When you look up a contact, it searches the web at that moment and returns results. The claimed database size of 1.7B+ contacts reflects this dynamic model, not a stored and verified inventory. For high-volume prospectors who prioritize list volume and recency over verified accuracy, the approach has appeal. The free plan includes 50 credits, and self-serve pricing is accessible.
Data accuracy is the most persistent issue, and it is widely documented. G2 reviewers report bounce rates well above what Seamless claims, and Trustpilot is at 2.5/5 with recurring complaints about billing practices and aggressive sales tactics. Teams where deliverability and compliance are priorities should evaluate the accuracy risk carefully before committing.
Pros
- Real-time search model can surface newer contacts that static databases miss
- Large claimed database with high-volume output capability
- Free plan with 50 credits; accessible self-serve pricing
- AI autopilot for automated prospecting list building
Cons
- Data accuracy widely reported as inconsistent; high bounce rates documented across hundreds of G2 reviews
- Trustpilot 2.5/5, with recurring complaints about billing practices
- Weaker compliance posture than GDPR-certified alternatives
- Aggressive upsell tactics and difficult cancellation processes reported
Pricing
Free plan: 50 credits. Paid plans start at $147/user/month. Enterprise pricing available on request.
What users say
“The data seems to be scraped without proper verification. I got hundreds of bounced emails.”
Best for
High-volume prospectors who prioritize list size and are prepared to run their own email verification layer on top. Teams with strict data quality, deliverability, or compliance requirements should run a proof-of-concept before committing.
10. RocketReach
RocketReach claims the largest database on this list at 700M+ professional profiles and 60M+ companies. It covers both email and phone lookups, with plans that include API access and bulk lookup functionality. Recruiters and marketers doing broad-scope research find it useful for its coverage breadth. Entry pricing is competitive at $33/mo on annual billing, and the API is capable for developers building contact lookup workflows.
Data accuracy is RocketReach’s most persistent weakness. G2 reviewers have tagged the platform with over 115 “Inaccurate Data” reviews and 111 “Outdated Contacts” reviews. Trustpilot sits at 1.2/5, with multiple reports of unauthorized renewal charges. Before committing, run a proof-of-concept against your actual ICP accounts to validate accuracy for your specific use case.
Pros
- Largest claimed database size at 700M+ professional profiles
- Covers both email and phone lookups in a single platform
- Affordable entry pricing at $33/mo annual; strong API for developers
- Broad use case coverage across sales, recruiting, and marketing research
Cons
- Data accuracy widely criticized: 115+ “Inaccurate Data” tags on G2
- Trustpilot 1.2/5, with reports of unauthorized card charges on renewal
- Intent and technographic signals only available on expensive higher-tier plans
- Main platform UI described as confusing across multiple G2 reviews
Pricing
Starts at $33/mo on annual billing. A free plan offers 5 lookups. Higher tiers include bulk API access and intent data.
What users say
“I’ve had to manually verify most contacts. Inaccurate data is the number one complaint across G2 reviews.”
Best for
Recruiters, marketers, and researchers needing broad professional database access at an affordable price. Teams where data accuracy drives outreach performance should run a trial before subscribing.
How to choose the right B2B data provider
The right tool depends on your team’s prospecting motion, not just database size. Here is how to think through the decision:
- If data accuracy is your top priority: Lusha (98% email, 86% phone) and UpLead (95% email guarantee with credit-back) offer the most credible accuracy commitments in the market.
- If you’re prospecting in EMEA and need phone data: Cognism’s Diamond Data program is the strongest option for human-verified European mobile numbers. Lusha is a strong alternative for teams that need both EMEA and North American coverage.
- If you’re a small team on a tight budget: Hunter.io (email only, from $34/mo) and Snov.io ($39/mo with built-in outreach) offer real value at the entry level. Lusha’s free plan (40 credits/month, no credit card) is worth starting with before committing to any paid tier.
- If you need data and outreach in one tool: Apollo.io is the most popular choice. If you want verified data that plugs into your existing sales engagement stack, Lusha integrates with Outreach, Salesloft, HubSpot, and Salesforce natively.
- If you’re running HubSpot and want enrichment natively: Clearbit (HubSpot Breeze) is purpose-built for this workflow. If you’re on Salesforce or another CRM, Lusha’s CRM enrichment integrations cover the same use case across multiple platforms.
- If you’re an enterprise team with US-heavy outbound and a large budget: ZoomInfo’s database depth and intent coverage are unmatched for that specific combination, though the pricing and contract terms are a significant commitment.
For most revenue teams, the decision comes down to three variables: the geographic markets you’re targeting, whether you need phone data or email-only coverage, and whether you want real-time signals alongside contacts. Lusha is built to cover all three without requiring an enterprise contract. Start with the free plan to test accuracy against your specific ICPs before scaling.
Frequently asked questions
What is the best B2B data provider in 2026?
The best overall B2B data provider for most teams is Lusha, which combines 98% email accuracy, 86% phone accuracy, real-time buying signals, and a broad compliance posture at a price accessible to SMBs and mid-market teams. ZoomInfo is the strongest choice for large enterprise teams focused on US outbound with a large budget. Apollo.io is the best value for teams wanting data and outreach in one platform. The right choice depends on your geographic focus, budget, and whether you prioritize email accuracy, phone data, or buying signals.
How much do B2B data providers cost?
Pricing varies widely. Free plans are available at Lusha (40 credits/mo), Apollo.io (50 email credits/mo), Hunter.io (25 searches/mo), and Snov.io (50 credits/mo). Self-serve paid plans range from $33/mo (RocketReach) to $147/mo (Seamless.ai). Enterprise platforms like ZoomInfo and Cognism typically start at $15,000/yr on annual contracts. Lusha’s paid plans start at $37/mo on annual billing, making it one of the most accessible options with verified accuracy backing the price.
What should I look for in a B2B data provider?
Focus on five things: data accuracy (email deliverability and phone hit rate against your actual ICP, not just claimed figures), geographic coverage for your target markets, compliance posture (GDPR and CCPA at minimum), integration depth with your CRM and sales tools, and pricing flexibility. Buying signals are a meaningful differentiator that separates full-platform providers from pure contact databases. Always run a proof-of-concept on your own accounts before committing to a long-term contract.
What is the difference between a B2B data provider and a sales intelligence platform?
A B2B data provider gives you contact and company information. A sales intelligence platform adds a layer of signals, AI recommendations, and workflow automation on top of that data. Lusha, ZoomInfo, Apollo.io, and Cognism are sales intelligence platforms that include B2B data. Hunter.io and RocketReach are closer to pure contact databases with limited intelligence features.
Conclusion
The best B2B data provider for your team depends on where you sell, how you sell, and what accuracy standard your outreach requires. For most SMB and mid-market revenue teams, Lusha’s combination of verified data, real-time buying signals, broad compliance, and accessible pricing makes it the strongest starting point. ZoomInfo wins on enterprise US database depth. Cognism wins on EMEA phone accuracy. Apollo.io wins on all-in-one SMB value.
If you’re still evaluating, the fastest way to test data quality against your own ICP is to start with a free plan. Lusha’s free tier includes 40 credits per month with no credit card required, which is enough to validate accuracy on your specific target accounts before making any commitment.
