B2B reps spend more than 30% of their day researching prospects instead of selling. The right sales intelligence tool flips that ratio. Below, we compare 10 platforms: what they cost, how accurate the data is, where each one fits, and which to pick for your revenue stack.
TL;DR – Quick Picks
The best sales intelligence tools in 2026 are Lusha (best overall for verified contact data and buying signals), ZoomInfo (best for enterprise US teams needing deep org charts), and Apollo.io (best for startups wanting data and outreach in one tool).
What is sales intelligence?
Sales intelligence is the data, signals, and insights revenue teams use to find, qualify, and prioritize buyers by combining verified contact information, firmographic and technographic context, and real-time buying signals so reps reach the right person at the right account at the right time. B2B contact data decays at roughly 30% per year across CRM benchmarks, which is why most revenue teams treat sales intelligence as a continuous operating layer, not a one-off list pull.
- Core capability: Find verified contacts (emails, direct dials), enrich account and contact records with firmographic, technographic, and intent data, and surface signals, job changes, funding rounds, technology installs and web visits that indicate active buying behavior.
- Primary users: SDRs and AEs (prospecting and outreach), RevOps (CRM hygiene, routing, account scoring), marketing ops (ABM list-building, lead scoring), recruiters (sourcing), and increasingly AI agents that need a verified data source.
- Key benefit: Reps spend less time researching and more time selling. Furthermore, the accounts they reach are pre-qualified by intent, not just by ICP filter.
- Sales intelligence vs. lead generation: Lead generation creates net-new records. Sales intelligence makes existing records useful; it verifies contacts, scores accounts, and surfacing the timing signal that tells you when to act. See our sales intelligence glossary entry for the full breakdown.
Below, we evaluated 10 sales intelligence tools against the criteria most revenue teams ask about: data accuracy, geographic coverage, buying signals, integrations, compliance, and pricing.
How we evaluated each sales intelligence tool
“Best” depends on where your buyers live, what’s already in your CRM, and how much you need to act on signals, not just append data. We pulled current data on each tool from G2, Capterra, vendor sites, and pricing pages, then weighted six criteria:
- Data accuracy: Verified email and phone hit rates (comparing claimed vs. real-world performance) with G2 review evidence.
- Database coverage: Contact and company volume, with attention to geography (US, EMEA, APAC).
- Buying signals: Job changes, funding, hiring, intent, technographic changes, as well as how actionable each signal is inside the workflow.
- Compliance: GDPR, CCPA, SOC 2, and ISO certifications based on real audits, not self-declared.
- Workflow fit: Native CRM connectors (Salesforce, HubSpot), engagement platforms (Outreach, Salesloft), automation tools, APIs, and AI agents: does it plug into the stack you already run?
- Pricing transparency: Whether the tool publishes price tiers or hides everything behind a sales call.

1. Lusha
Why we ranked it #1
Lusha is a B2B data provider and sales intelligence platform that helps GTM teams find verified contacts and companies, enrich records, and act on buying signals across the CRMs, sales tools, automation platforms, APIs, and AI agents they already use.
The database covers 300M+ contacts (152M emails, 300M direct dials) and 30M company profiles, with 98% email accuracy and 86% phone accuracy, backed by a crowdsourced community of 1M+ users across 223,000+ organizations including Google, Microsoft, Amazon, and Salesforce.
For sales intelligence specifically: Lusha pairs verified contact data with real-time buying signals (such as job changes, funding rounds, technology installs, and intent) so reps reach accounts when they’re actually in-market, not just because they match an ICP filter.
AI recommendations score prospects against your past wins, and the enrichment API handles programmatic flows for RevOps teams that wire sales intelligence into their own pipelines or AI agents.
Compliance is genuine, not asserted: GDPR, CCPA, ISO 27001, ISO 27017, ISO 27701, ISO 31700, and SOC 2 Type 2, along with a public Trust Center and opt-out mechanism. That matters when legal asks where the data came from.
Pros
- 98% email accuracy and 86% phone accuracy – verified by community contribution plus AI.
- 300M+ contacts with strong North America coverage and growing EMEA via crowdsourced data.
- Real-time buying signals built in (job changes, technographics, funding, intent), not a separate product.
- Both company and contact data, including verified emails and direct dials.
- Plugs into the stack you already run: Salesforce, HubSpot, Outreach, Salesloft, Pipedrive, Zapier, API, plus Chrome extension. See our CRM enrichment workflow for the full setup.
- Broadest compliance posture in the category (six ISO certifications + SOC 2 Type 2).
- Free plan with 40 credits/mo and no credit card.
Cons
- Smaller raw database than ZoomInfo.
- Fewer native integrations than enterprise platforms (though all major CRMs and engagement tools are covered).
- EMEA phone coverage is solid but trails Cognism’s Diamond Data verification for UK mobile.
Pricing
Free, Starter ($37/mo annual), Professional ($52.45/mo annual), and Premium ($299.95/mo annual for 5 seats). Annual billing saves 25%. Professional and Premium include credit rollover, meaning unused credits carry forward up to 2× the monthly allocation. See Lusha’s pricing for the full breakdown.
What users say
“Lusha’s direct contact information is worth more than gold. The Chrome extension makes prospecting feel effortless.”
Best for
Revenue teams (ranging from solo SDRs to mid-market RevOps) that want a flexible sales intelligence platform spanning verified contacts, enrichment, buying signals, and automation, across the tools they already run. No enterprise contract, no six-figure budget. If you’re an SMB, our sales intelligence for SMBs page covers the typical setup.
2. ZoomInfo
Overview
ZoomInfo is the deepest US-focused B2B database (260M+ contacts, 100M+ companies) with Bombora-powered intent data, conversation intelligence, an AI Copilot for prospecting, and a built-in engagement layer. For US enterprise sales orgs running ABM, the breadth is hard to match. The trade-off shows up at signing time: annual-only contracts starting around $15,000/yr, and an implementation footprint that typically requires a dedicated admin.
Pros
- Largest US contact database in the category and deepest intent data via Bombora.
- AI Copilot recommends prospects and drafts outbound at scale.
- 50+ native integrations across the GTM stack.
Cons
- Annual-only contracts starting around $15,000/yr, which is prohibitive for SMBs.
- EMEA and APAC data quality is significantly weaker than US.
- Enterprise-heavy buying process; complex setup; aggressive upselling at renewal.
Pricing
Annual contract, starting around $15,000/yr. Trial only – no free plan.
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.” G2 reviewer
Best for
US-focused enterprise teams with budget for an annual contract and a dedicated admin. If the price tag or the enterprise-heavy buying motion is a dealbreaker, choose Lusha for verified data, enrichment, and signals at a self-serve price.

3. Apollo.io
Overview
Apollo bundles a 275M+ contact database with a built-in sequencer, dialer, and AI email writer. For SMBs that want one tool instead of three, it’s compelling and the free plan with 50 monthly email credits is generous. Phone accuracy is the soft spot: G2 reviewers routinely report that roughly half the numbers they try are wrong or outdated.
Pros
- Best value all-in-one platform in the market.
- Built-in outreach removes the need for a separate engagement tool.
- Highest G2 rating in the category (4.7/5).
Cons
- Phone number accuracy is inconsistent, a fact widely reported in G2 reviews.
- Bundled engagement is wasted spend if you already use Outreach or Salesloft.
- Credit-based model limits heavy users at lower tiers; support response times lag.
Pricing
Free tier with 50 email credits/mo. Paid plans from $49/user/mo (annual).
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 data and outreach in one bundle. If your priority is verified B2B data and enrichment that plugs into the GTM stack you already run (rather than another sequencer), Lusha is the cleaner fit.

4. Cognism
Overview
Cognism’s Diamond Data® standard human-verifies mobile phone numbers; consequently, the hit rate in EMEA is better than US-first competitors. The 400M+ contact database leans European, and the GDPR compliance posture is among the strongest in the category. The trade-off: no transparent pricing, annual contracts only, and a narrower workflow surface than the all-in-one platforms.
Pros
- Industry-leading EMEA mobile phone accuracy via human verification.
- Strongest GDPR positioning in the category.
- Clean, modern UI.
Cons
- Expensive with no transparent pricing (~$15,000/yr custom).
- Weaker US and APAC coverage vs. ZoomInfo.
- No built-in outreach; fewer automation integrations.
Pricing
Annual contract, ~$15,000/yr custom. Trial only.
What users say
“Their Diamond Data verification for phone numbers is genuinely impressive, much better hit rate than ZoomInfo for UK numbers.”
Best for
EMEA-focused teams that need verified European mobile and a hard-line GDPR posture. If you want a flexible sales intelligence platform that spans prospecting, enrichment, signals, and automation (not just EMEA phone coverage) Lusha covers more of the GTM workflow.

5. LinkedIn Sales Navigator
Overview
Sales Navigator gives you access to the live LinkedIn network: 1B+ self-updated professional profiles, relationship intelligence, warm intro paths, and Account IQ summaries. The catch: no direct email or phone data in the base tier and no export. You’re renting access to the network, not owning the contacts.
Pros
- Only tool with access to real LinkedIn network data: relationships, warm paths, smart links.
- Profiles are always-current because LinkedIn members update them.
- Global coverage wherever LinkedIn adoption is strong.
Cons
- No direct email or phone data; therefore, you need a separate tool (often paired with Lusha or Kaspr) for actual contact details.
- Cannot export contact data; consequently, you’re locked into the LinkedIn workflow.
- Expensive at $119.99/mo for what you don’t get to keep.
Pricing
$119.99/mo (Core). Advanced and Advanced Plus tiers run higher.
What users say
“You can’t export the data; instead, you’re essentially renting access to LinkedIn’s network, not owning anything.”
Best for
Teams that prospect heavily on LinkedIn and value relationship intelligence over raw contact data. Most teams pair Sales Navigator with a contact-data tool; for instance, Lusha’s Chrome extension overlays verified emails and direct dials directly on Sales Navigator profiles so reps can work in one tab.

6. 6sense
Overview
6sense is account intelligence, not contact data; in fact, it’s one of the category leaders for predictive ABM. The platform identifies anonymous buyers on your website, scores accounts by buying stage, and orchestrates plays across the revenue stack. Contact data is included but secondary; the value is in the intent prediction and the orchestration layer.
Pros
- Best-in-class predictive account scoring and buying stage models.
- Identifies anonymous web visitors and ties them to known accounts.
- Integrates deeply with Salesforce, HubSpot, Marketo, Outreach, and Salesloft.
Cons
- Very expensive ($25,000–$300,000+/yr).
- Extremely steep learning curve; implementation typically takes 2–3 months.
- Phone and email accuracy are not the primary strength; intent scores are opaque.
Pricing
Annual enterprise contract, starting around $25,000/yr. Limited free tier for basic features.
What users say
“Intent scores feel opaque; you can’t easily see what signals drove a score to Decision stage.”
Best for
Enterprise marketing and revenue ops teams running mature ABM programs with dedicated ops capacity. If you want intent signals baked into a contact-data platform (rather than a separate $25K/yr orchestration product), Lusha’s buying signals cover the most common plays without the implementation cost.
See how it stacks up: Lusha vs 6sense | Best 6sense Alternatives.
7. Clay
Overview
Clay isn’t a database; it’s a workflow tool that pulls from 100+ providers (Lusha, ZoomInfo, Apollo, Hunter, Cognism, and others) in a waterfall: try provider A, fall through to B if no match, and so on. The result is the highest possible match rate per record, plus AI agents that can do prospect research, draft emails, and run custom workflows. Match rate is the upside; complexity is the trade-off.
Pros
- Highest match rates in the category via multi-source waterfall.
- AI agents handle research, list building, and personalization at scale.
- Integrates with every major CRM and 100+ data providers, including Lusha.
Cons
- Steep learning curve – most teams need a dedicated RevOps engineer to run it well.
- You still pay underlying provider costs on top of Clay’s subscription.
- Credit costs climb quickly across providers at scale.
Pricing
Free plan with 100 credits, Starter at $149/mo, scaling up from there. Provider credit costs are separate.
What users say
“Clay is incredibly powerful but you need a RevOps engineer to actually use it well.”
Best for
RevOps teams with technical operators who want to combine multiple sources into a single waterfall and squeeze every extra match out of their lists. Many teams use Lusha as the highest-priority provider inside their Clay waterfall.

8. Amplemarket
Overview
Amplemarket refreshes its 70M+ contact database weekly, which keeps bounce rates under 3%. The platform is AI-first: the Duo Copilot writes outbound, suggests prospects, and handles personalization. Bundled multi-channel sequencer (email + LinkedIn + dialer) means it can replace a separate engagement tool, if you don’t already have one.
Pros
- Weekly data refresh keeps bounce rates exceptionally low.
- Duo AI Copilot is genuinely useful for first-touch email drafts.
- Bundled multi-channel outbound across email, LinkedIn, and dial.
Cons
- Custom pricing only, with no transparent self-serve plan.
- Newer and less battle-tested than ZoomInfo or Cognism in enterprise rollouts.
- Bundled engagement is wasted spend if you already use Outreach or Salesloft.
Pricing
Custom annual contract, estimated ~$120/user/mo. No free plan.
What users say
“The AI copilot writes better first-touch emails than my reps do.”
Best for
Mid-market outbound teams that want AI-assisted prospecting and don’t already have an engagement platform.
9. LeadIQ
Overview
LeadIQ is built for teams whose engagement stack runs on Outreach or Salesloft. The CRM sync is deep, job change tracking surfaces warm outreach triggers, and the Scribe AI assistant personalizes first-touch emails. Database is ~100M+ contacts, US-leaning, with phone accuracy that lags ZoomInfo and Lusha.
Pros
- Deepest Outreach/Salesloft integration in the category.
- Job change tracking surfaces warm signals automatically.
- Scribe AI writes personalized first-touch emails.
Cons
- Smaller database than ZoomInfo or Apollo; therefore, coverage gaps are common.
- Lower phone accuracy, especially for non-US contacts.
- No intent signals beyond job change.
Pricing
Free plan with 20 credits/mo. Paid plans from $36/user/mo.
What users say
“Database is noticeably smaller than ZoomInfo or Apollo — found many contacts missing.”
Best for
Mid-market sales teams running Outreach or Salesloft that want clean CRM sync and warm-trigger automation. If database depth or buying signals beyond job change matter, look elsewhere.
See how it stacks up: Best LeadIQ Alternatives.
10. SalesIntel
Overview
SalesIntel pairs a smaller database (22M+ human-verified contacts, 54M+ mobile numbers) with a research-on-demand team; consequently, if a contact you need isn’t in the database, they’ll research and add it. The GTMCanvas workflow builder lets ops teams stitch 30+ intent signals into custom automations. Strongest for mid-market US teams.
Pros
- High human-verified phone accuracy for US mobile.
- Research-on-demand for hard-to-find contacts.
- 30+ intent signals + technographics built into GTMCanvas workflows.
Cons
- Smaller database vs. ZoomInfo, Apollo, or Cognism.
- Mixed reviews on AI-generated data accuracy.
- Weaker EMEA coverage.
Pricing
$69/user/mo entry tier. 14-day trial with 50 credits.
What users say
“SalesIntel displays AI generated data which is often not accurate — I’ve caught several contacts with wrong details.”
Best for
Mid-market US revenue teams that value human-verified phone data and want a research-on-demand team for niche contacts.
See how it stacks up: Best SalesIntel Alternatives.
How to choose the right sales intelligence tool
No single tool wins every use case. Match the tool to the constraint that matters most for your team:
- If you want verified data + buying signals across your existing stack: Lusha gives you 98% email accuracy, 86% phone accuracy, real-time signals (job changes, intent, funding, tech installs), and integrations with the CRMs, sales tools, automation platforms, APIs, and AI agents you already use — from $37/mo, no annual contract.
- If you’re a US enterprise with budget and a dedicated admin: ZoomInfo’s database depth and Bombora intent are hard to beat — if you can absorb the enterprise-heavy buying process.
- If you’re an SMB and want data + outreach bundled: Apollo’s all-in-one is the value play. Watch phone accuracy.
- If you’re EMEA-focused and GDPR-bound: Cognism’s Diamond Data verification for European mobile is the category leader for phone hit rate. Lusha covers a broader workflow if you also need signals, automation, and AI agents.
- If you prospect heavily on LinkedIn: Use Sales Navigator for relationship intelligence and pair it with Lusha to actually reach the people you find.
- If you run mature ABM with dedicated ops: 6sense for predictive account scoring. Expensive, but no substitute at the high end.
- If you have a RevOps engineer: Clay lets you waterfall across providers, including Lusha, for maximum match rate.
- If your engagement stack is Outreach or Salesloft: LeadIQ for the deep CRM sync and job change triggers.
- If you need human-verified US mobile phone data: SalesIntel’s research-on-demand team is unique.
For most revenue teams, the right starting point is the tool that combines accuracy, compliance, accessible pricing, and a workflow that fits the stack you already run while avoiding an enterprise contract before you’ve proven ROI.
That’s why Lusha sits at #1: it covers verified contacts, enrichment, and buying signals across the GTM workflow, at a price most teams can self-serve.
FAQs
What is the best sales intelligence tool?
For most revenue teams, Lusha is the best overall: 98% email accuracy, 86% phone accuracy, real-time buying signals, integrations across the major CRMs, engagement tools, automation platforms, APIs, and AI agents, and pricing from $37/mo with a free plan. ZoomInfo is the deepest US enterprise option; Cognism is strongest for EMEA; 6sense is the ABM specialist. The “best” tool depends on your geography, budget, and stack.
How much do sales intelligence tools cost?
Pricing ranges from free tiers (Lusha, Apollo) to $300,000+/yr enterprise contracts (6sense, ZoomInfo with full intent). Self-serve mid-market tools sit between $37/mo (Lusha Starter) and $149/mo (Clay). Annual enterprise contracts (ZoomInfo, Cognism, 6sense) typically start around $15,000/yr and have no transparent pricing.
What’s the difference between sales intelligence and lead generation?
Lead generation creates net-new prospect records. Sales intelligence makes records useful by verifying contacts, enriching firmographic and technographic context, and surfacing the buying signals that tell you when an account is in-market. Modern tools (Lusha, Apollo, ZoomInfo) do both, but the workflows are distinct.
What buying signals should a sales intelligence tool surface?
Look for job changes (a contact moving to a new company is one of the highest-intent signals in B2B), funding rounds (cash to spend), hiring trends (team scaling = budget for tools), technology installs and removals (technographic intent), and website intent data (anonymous visitor identification). Lusha, ZoomInfo, and 6sense all cover the core set; the value is in how cleanly the signal lands inside your workflow.
Is sales intelligence data GDPR-compliant?
It can be, provided the vendor sources data legitimately, lets people opt out, and holds real certifications (not self-declared). Lusha holds GDPR, CCPA, ISO 27001/27017/27701/31700, and SOC 2 Type 2. Cognism is also GDPR-strong. If a vendor only claims “self-declared compliance,” dig deeper before buying.
Can I integrate sales intelligence with Salesforce or HubSpot?
Yes; every tool on this list integrates with Salesforce, and most integrate natively with HubSpot. Setup specifics vary by tool. For Lusha, the CRM connectors handle bulk enrichment, automated record refresh, and real-time signals routed to the right rep.
Conclusion
The best sales intelligence tool isn’t the one with the biggest database or the loudest AI marketing; rather, it’s the one that matches your team’s stack, geography, compliance bar, and budget. For most B2B revenue teams, Lusha sits at the intersection of accuracy, accessible pricing, genuine compliance certification, and workflow fit across the tools you already run. Start with the free plan, prove the ROI, and scale from there.
