We review this list regularly. Vendors can request a listing, send updated pricing or ask about featured placement.
Sales intelligence tools answer two questions, who to contact and when to contact them. Contact data covers names, emails, direct dials, job titles, and company details. Intent and signal data adds timing, such as funding, hiring, tech changes, or research activity that suggests a buying window. The tools below differ on coverage, accuracy, compliance, and price, so the right choice depends on team size, market, and whether you need data alone or data plus outreach.
#1ZoomInfo
Best for: Enterprise contact data4.5/5 on

Starting priceSee website
Free planFree trial
ZoomInfo is the enterprise standard for B2B contact data. The platform combines contact and company records with buyer intent signals, technographics, and website visitor identification, so reps can prioritize accounts that are already researching a topic. Direct dial coverage is a key advantage over many rivals, especially for North American outreach. CRM enrichment keeps records updated, and integrations with Salesforce, HubSpot, and Outreach support a full go-to-market workflow.
The cost and contract structure are the main barriers. Pricing is quote based and often runs to five figures per year, with annual contracts. Small teams with low prospecting volume will not use the full platform, and simpler tools offer better value. For a mid-market or enterprise team that needs depth, phone coverage, and intent in one contract, ZoomInfo is the benchmark.
What we like- Very large contact and company database
- Strong direct dial coverage
- Buyer intent and website visitor tracking
- CRM enrichment and integrations
Watch out for- Quote based enterprise pricing
- Long contracts in many cases
- Heavy for small teams and low volume prospecting
Starting price$49 per user/month
Free planYes
Apollo.io combines a contact database with sales engagement in one tool, which is why startups favor it. Users can search contacts, build lists, enrich records, and run email sequences without buying a second tool. The free plan lets a small team test data quality, and paid tiers start near $49 per user per month on annual billing in many listings. Integrations with Salesforce and HubSpot keep prospecting data in the CRM.
Data accuracy is not as consistent as ZoomInfo, especially for senior roles and non-US markets, so teams should verify key contacts before a campaign. Sequencing is solid for basic outbound, but teams that need advanced multichannel workflows may still need a dedicated engagement tool. For a small or mid-market team that wants data plus outreach at a clear price, Apollo is the best value in this list.
What we like- Large contact database
- Built-in sequencing and outreach
- Free plan for testing
- CRM integrations
- Affordable paid tiers
Watch out for- Data accuracy varies by region and seniority
- Outreach features are simpler than dedicated sequencers
- Credit limits apply
#3Clay
Best for: Waterfall enrichment workflows4.6/5 on
G2 (234 reviews, checked Oct 2026)
Visit clay.com
Starting price$185 per month
Free planYes
Clay is not a traditional database. It is a workflow tool that enriches a list by trying multiple data providers in sequence, a process called waterfall enrichment, until it finds the best email, phone, or company detail. That approach improves match rates compared with a single source, and AI agents can research accounts, score leads, and draft outreach context. RevOps teams use Clay to build repeatable prospecting systems that feed the CRM.
The learning curve is real. Clay requires setup, provider choices, and credit management, and costs rise as volume grows. A single rep who just wants a list will find Apollo or Lusha faster. For a growth team that wants custom enrichment, signal based lists, and automation, Clay is the most flexible tool in this guide.
What we like- Waterfall enrichment across many providers
- Flexible workflows and AI agents
- Strong for RevOps and GTM engineering
- CRM sync
Watch out for- Learning curve is steep
- Needs an ops minded user to set up
- Costs rise with credits and providers
- Not a simple list tool
#4Cognism
Best for: EU and GDPR focused data4.5/5 on

Free planNo
Cognism is the best choice for European outbound. Its Diamond Data includes phone verified mobile numbers, which improves connect rates for EU prospecting, and its compliance focus suits regulated markets where GDPR matters. Intent signals, job change alerts, and technographics help reps time outreach, and integrations with Salesforce, HubSpot, and Outreach support standard workflows.
Pricing is quote based and premium, which can be hard for small teams to justify. North American coverage is solid but not as deep as ZoomInfo. For a team selling into Europe, or a regulated industry where compliance is non-negotiable, Cognism offers data quality and legal grounding that US focused tools often lack.
What we like- Strong EU coverage
- Phone verified mobile data
- GDPR focused compliance
- Intent signals and sales triggers
- CRM integrations
Watch out for- Quote based pricing
- Premium price for small teams
- Less North American depth than ZoomInfo
#5LinkedIn Sales Navigator
Best for: Relationship prospecting4.4/5 on

Visit linkedin.com
Starting price$99.99 per user/month
Free planFree trial
LinkedIn Sales Navigator is not a contact database in the ZoomInfo sense, but it is essential for relationship led prospecting. Advanced search, lead lists, org charts, and job change alerts help reps find the right buyer and a warm introduction path. InMail credits allow direct messages to prospects outside the network, and account pages show growth, hiring, and leadership changes.
The gap is contact data. Sales Navigator does not provide emails or direct dials by default, so teams often pair it with Lusha, Apollo, or Clay for contact details. Pricing starts near $99.99 per user per month for Core in many listings, which is high for data alone. For account based selling and social prospecting, Sales Navigator is a core tool, best used alongside a contact provider.
What we like- Direct access to LinkedIn network and org charts
- Advanced search and lead recommendations
- InMail credits
- Relationship mapping
Watch out for- No direct dials or emails by default
- Higher price for data alone
- Requires LinkedIn activity to get full value
#6Lusha
Best for: Budget contact lookups4.3/5 on
G2 (1,668 reviews, checked Oct 2026)
Visit lusha.com
Starting price$37.45 per user/month
Free planYes
Lusha is built for quick contact lookups. The browser extension reveals emails and phone numbers on LinkedIn and company websites, making it ideal for individual reps who need a contact fast. The free plan offers a small credit allowance, and paid tiers start near $37.45 per user per month on annual billing in many listings. Setup is minimal, and the tool fits a rep workflow without a large platform rollout.
Lusha is not a full sales intelligence platform. It lacks sequencing, deep intent data, and CRM enrichment at the level of ZoomInfo or Clay. Accuracy varies by market, so verify high value contacts. For a small team or solo rep that needs budget friendly lookups, Lusha is a practical choice.
What we like- Simple browser extension
- LinkedIn first workflow
- Free plan for testing
- Affordable paid tiers
- Quick email and phone lookups
Watch out for- No sequencing or CRM enrichment depth
- Accuracy varies by region
- Credit limits apply
#7LeadIQ
Best for: LinkedIn to CRM prospecting4.2/5 on
G2 (1,186 reviews, checked Oct 2026)
Visit leadiq.com
Starting price$15 per user/month
Free planYes
LeadIQ focuses on the prospecting workflow for SDR and BDR teams. One click capture moves a LinkedIn profile into the CRM with contact details, saving manual data entry and reducing errors. The free plan suits testing, and Pro pricing starts near $15 per user per month on annual billing in many listings. Integrations with Salesforce and HubSpot keep lists in sync.
The database is smaller than the leaders, and LeadIQ does not offer the same intent or enrichment depth as ZoomInfo, Cognism, or Clay. It works best as a workflow layer on top of LinkedIn, paired with a larger data source for list building. For SDR teams that live on LinkedIn, LeadIQ speeds up daily prospecting.
What we like- One click LinkedIn to CRM capture
- Simple prospecting workflow
- Free plan
- Affordable Pro tier
- Salesforce and HubSpot sync
Watch out for- Smaller database than ZoomInfo and Apollo
- No deep intent platform
- Credit limits on lower plans
#8UpLead
Best for: Verified lists for SMBs4.7/5 on
G2 (831 reviews, checked Oct 2026)
Visit uplead.com
Starting price$74 per month
Free planFree trial
UpLead targets small and mid-market teams that want verified lists without enterprise pricing. Contacts are verified at download in many listings, with an accuracy guarantee that reduces bounces. List building uses firmographic and technographic filters, and exports are simple. Essentials pricing starts near $74 per month on annual billing in many listings, making it accessible for SMBs.
The database is smaller than ZoomInfo and Apollo, and intent data is thinner. Credit based pricing also limits high volume prospecting. UpLead fits a team that needs reliable lists for a defined market, at a predictable price, without paying for a full enterprise platform.
What we like- Verified contact data with accuracy guarantee in many listings
- Simple list building
- Technographic filters
- Affordable for SMBs
Watch out for- Smaller database than leaders
- Fewer intent signals
- Credit based pricing can limit volume
How we chose
We compared pricing pages, documentation, and public reviews on G2, Capterra, and Reddit, focusing on contact coverage, phone accuracy, email verification, intent signals, compliance, CRM integrations, and total cost for a small team versus an enterprise team. Tools were scored on data quality for US and EU markets, workflow fit for reps versus RevOps, and whether pricing is published or quote based. Company size was considered for support and stability, but smaller tools were included when they offered a clear workflow or price advantage. Prices change by seat count, credits, and billing term, so confirm the current plan at checkout.
Choosing by team size and market
Start with team size. A solo rep or startup should start with Apollo or Lusha, since both offer free plans and clear pricing. A mid-market team that needs depth and intent should compare ZoomInfo and Cognism, depending on whether the market is North America or Europe. A RevOps led team that wants custom enrichment should evaluate Clay. Always test data quality on your own target list before signing, since accuracy varies by industry, seniority, and region more than marketing claims suggest.
Data quality, compliance, and credits
Test a sample of 100 contacts from your ideal customer profile, checking email validity, phone accuracy, and title correctness. Review compliance for your market, especially GDPR for EU outreach and CCPA for California, and confirm how the vendor sources and verifies data. Understand credit models, since some tools charge per contact, per enrichment, or per seat, and costs can rise sharply with volume. A trial that covers your real list is more useful than a demo with sample data.
Frequently asked questions
What is the best sales intelligence tool for B2B contact data?
ZoomInfo is the strongest enterprise choice for depth and phone coverage, while Apollo is the best value for startups and small teams. Cognism leads for EU data, and Clay leads for custom enrichment workflows. The best tool depends on team size, market, and budget.
Is Apollo better than ZoomInfo?
Apollo is better for small teams that want data plus outreach at a clear, lower price. ZoomInfo is better for enterprise teams that need deeper phone coverage, intent data, and CRM enrichment at scale. Test both on your target list, since accuracy varies by industry and region.
What is waterfall enrichment in Clay?
Waterfall enrichment tries multiple data providers in sequence until it finds the best contact detail, rather than relying on one database. That approach improves email and phone match rates, especially for hard to find contacts. Clay charges credits per provider step, so costs depend on list size and provider choices.
Do sales intelligence tools provide phone numbers?
Yes, most do, but phone coverage varies widely. ZoomInfo and Cognism offer strong direct dial and mobile coverage, while Apollo and Lusha offer phone data with varying accuracy. LinkedIn Sales Navigator does not provide phone numbers by default, so pair it with a contact provider for calling.
Are these tools compliant with GDPR?
Cognism is built with GDPR compliance as a core focus, and other vendors offer compliance features, but compliance also depends on how your team uses the data. Review each vendor data sourcing, consent, and deletion policies, and get legal advice for regulated outreach. Never assume a tool alone makes outreach compliant.
How much do sales intelligence tools cost?
Costs range from free plans at Apollo, Lusha, and LeadIQ, to $49 per user per month at Apollo, $185 per month at Clay, and quote based enterprise pricing at ZoomInfo and Cognism. Credit volume, seat count, and add-ons change the total, so get a quote for your team size and list volume.
