Kaspr vs. Lusha (vs. ZoomInfo): Which B2B Contact Data Tool Should You Choose in 2026?

Choosing between Kaspr and Lusha for your B2B prospecting often comes down to five questions:

• Are you prospecting primarily in Europe, or do you need global coverage?

• Do you need a LinkedIn enrichment tool, or a platform that also handles outreach, signals, and automation?

• Is your team small enough to work within credit-based limits, or do you need volume at scale?

• How important is compliance documentation when selling into regulated industries?

• Do you want contact data alone, or intelligence that tells you which contacts to prioritize and why?

Here's what we recommend:

Kaspr is built for individual contributors and small sales teams who prospect on LinkedIn and need European phone numbers fast. Its Chrome Extension surfaces contact data on LinkedIn profiles, Sales Navigator, groups, events, and post engagers, with a free tier that requires no credit card. Backed by parent company Cognism's data, Kaspr offers 200M+ European B2B contacts and unlimited B2B email credits on paid plans starting at $49/user/month. But Kaspr's phone credit caps create friction at volume, it has no native outreach or sequencing, and its data coverage outside Europe is thin.

Lusha serves a broader range of GTM teams with 280M+ verified contacts, buying signals powered by Bombora intent data, AI prospect recommendations, and a native email sequencing tool called Engage. Lusha's compliance stack runs unusually deep for a sales intelligence vendor, with ISO 27001, ISO 27701, SOC 2 Type II, and nine total certifications. While Lusha has expanded well beyond contact lookup, its outreach is email-only, its conversation intelligence product is still in beta, and phone reveals cost 5 credits each, which adds up fast.

Both tools solve the core problem: finding verified contact data for outbound prospecting. But teams that outgrow credit-based enrichment, need multi-channel execution, or want intelligence that explains why a deal is moving (not just who to call) eventually hit their limits. That's where a full GTM platform changes the equation.

ZoomInfo is an AI-powered GTM platform built on the largest B2B dataset available: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails.

That data fuels ZoomInfo's GTM Context Graph, an intelligence layer that connects your CRM records, conversation transcripts, and behavioral signals with the 1.5B+ data points ZoomInfo processes daily.

The result: the AI drafting your next email follow-up understands the concern behind the conversation, your next GTM play targets accounts matching your actual win patterns, and your next forecast reflects buying evidence rather than rep optimism.

Your team can use this intelligence through the GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP in any front-end.

If your team needs more than contact data (prioritized accounts, multi-channel orchestration, and AI that understands your deals), see how ZoomInfo works.

Kaspr vs. Lusha vs. ZoomInfo at a glance

European data is Kaspr's territory, Lusha plays globally

Kaspr was founded in Paris in 2018 to become the first French B2B data provider. After its 2022 acquisition by Cognism, the database grew through a data merge, but the core strength remains European mobile numbers.

The sales page says it plainly: "Europe is our home and where we provide unmatched data quality."

Customer stories confirm this. Cloud Direct's SDR Manager switched to Kaspr because a previous provider's phone numbers were "poor quality — it would pull American numbers when it was a UK-based person." Focus Cloud Group's CEO switched because "the data available on Kaspr is much more accurate."

For teams selling into France, the UK, Germany, and Spain, Kaspr's data density in those markets is a real advantage.

Lusha takes a broader geographic approach. Its 280M+ contact database covers the US, Europe, and growing APAC markets. CARTO tripled outbound leads after switching to Lusha because their previous provider lacked UK and EU contact data.

NEXTGEN used Lusha to build a US contact base from scratch, delivering 10x more contacts in six months than prior tools.

Lusha also became compliant with the Australian Privacy Act in March 2025, signaling deliberate APAC expansion.

ZoomInfo's 500M contacts span 100M companies globally, with 34M+ company profiles and 45M+ mobile numbers outside North America. In 2025, ZoomInfo expanded international mobile coverage by 1.8 million numbers across six European markets.

For teams prospecting across multiple geographies, ZoomInfo's coverage removes the need to evaluate regional providers one by one.

Beyond contact data: signals and intelligence

Contact data gets you the who. Signals and intelligence tell you the when and why.

Kaspr is straightforward about this: it's a data tool. The Kaspr dashboard lets you organize leads and build enrichment workflows, but there's no native intent data (except on the Enterprise plan), no buying signals, and no outreach automation.

Kaspr enriches contacts and pushes them to CRMs or outreach tools. The prospecting workflow ends at the handoff.

Lusha has expanded into this territory. Buying Signals track job changes, funding rounds, hiring surges, and research activity through Bombora's intent data cooperative, which spans 4M unique domains and 16.3B monthly interactions.

AI Recommendations analyze your prospecting activity and surface lookalike prospects you haven't revealed yet, refreshing daily. Playlists auto-update with contacts matched to your ICP. These features reflect Lusha's bet that the future of prospecting is AI-curated rather than manually assembled.

ZoomInfo treats signals and intelligence as the platform's core, not an add-on.

The GTM Context Graph processes 1.5B+ data points daily, combining ZoomInfo's B2B data with your CRM records, conversation transcripts from Chorus, and behavioral signals to capture not just what happened, but why deals move or stall.

Source: ZoomInfo

Guided Intent (exclusive to ZoomInfo) identifies topics historically correlated with your actual deal wins, rather than requiring you to guess which keywords to track. Intent signals draw from 210 million IP-to-Organization pairings and 6 trillion+ keyword-to-device pairings monthly.

Source: ZoomInfo

The practical difference: Lusha can tell you a company is researching "sales intelligence tools." ZoomInfo can tell you that company's research pattern, combined with a recent VP hire and a champion's job change, matches the signal combination behind your closed-won deals in that segment.

That connection between signals and outcomes separates an intelligence layer from a database with alerts.

Outreach and execution capabilities

Finding contacts matters less if you can't act on them.

Kaspr has no native outreach. It integrates with Lemlist for email sequences, Aircall and Ringover for dialing, and HubSpot, Salesforce, Pipedrive, and Zoho for CRM sync.

The workflow: enrich in Kaspr, push to another tool, execute there. This adds cost and complexity but lets you choose best-of-breed tools at each step.

Lusha introduced Engage, a native email sequencing tool included at no extra charge. It supports AI-generated multi-step sequences, personalization tags, and auto-enrollment when contacts are added to a list.

Source: Lusha

The constraint: Engage is email-only. No phone steps, no LinkedIn touches, no SMS. You're limited to 1,000 emails/user/day and 5 active sequences. For email-first outbound teams, it reduces tool sprawl. For multi-channel teams, you'll still need a separate engagement platform.

ZoomInfo approaches execution through multiple paths.

GTM Workspace gives sellers a single place for account research, outreach drafting, signal monitoring, and CRM updates. AI agents handle the administrative work that slows sellers down.

The Salesloft partnership provides multi-touch, multi-channel sequencing (phone and email) triggered by ZoomInfo's buying signals.

The LinkedIn workflow question

Kaspr has a clear advantage over Lusha for one specific workflow: prospecting inside LinkedIn.

Kaspr's Chrome Extension works on standard LinkedIn profiles, Sales Navigator lists, LinkedIn Events attendees, Group members, and Post engagers. The widget previews available data before spending a credit, so you see what you're getting before you pay.

Source: Kaspr

Bulk extraction processes up to 2,500 contacts from a Sales Navigator list in one automation, with logic that only charges you when the required data type (phone, email, or both) is found.

Lusha's Extension covers similar ground, working on LinkedIn, Sales Navigator, CRM interfaces, and B2B websites.

Source: Lusha

It supports individual and bulk export. But Kaspr's wider LinkedIn surface (events, groups, post engagers) gives it an edge for SDRs who mine LinkedIn signals for warm prospects.

Both extensions require Chrome. Neither scrapes LinkedIn data; both append contact information from their own databases.

ZoomInfo approaches LinkedIn prospecting differently.

Its ReachOut Chrome Extension works on LinkedIn and across the web, but the primary prospecting workflow happens inside GTM Workspace and ZoomInfo Sales, where 300+ company attributes, intent signals, and org charts are available without relying on LinkedIn as the starting point.

Credit structures determine real cost

Published pricing tells part of the story. Credit mechanics tell the rest.

Kaspr separates credits into four types: B2B email, phone, direct email, and export. Paid plans include unlimited B2B email credits (subject to a 10,000/month fair-use cap), but phone credits are capped: 1,200/year on Starter, 2,400/year on Business.

Export credits add another layer: 12,000/year on Starter, 30,000 on Business. Every export (not just the first) costs a credit.

For a five-person SDR team on Starter, that's roughly 240 phone credits per person per year, or 20 per month. Teams with high call volumes will need add-on credits, starting at $91 for 2,500 phone credits/year.

Lusha uses a single credit type, but costs vary by action: 1 credit for an email reveal, 5 credits for a phone number. The Starter plan includes 400 credits/month on monthly billing. Revealing 40 phone numbers exhausts that entire monthly allotment. The Pro plan starts at 600 credits/month for two seats.

For phone-heavy prospecting, Lusha's credit math gets expensive fast. The upside: re-revealing a previously unlocked contact costs nothing, and unused credits roll over up to 2x the monthly limit on Pro and Premium plans.

ZoomInfo uses a simpler model: 1 credit = 1 export of a contact or company profile. Searching and viewing data within the platform is free. Credits come with the subscription, with volume depending on the plan. Pricing is custom-quoted, which means higher upfront investment but no per-data-type surcharges.

For teams that need both emails and phone numbers at volume, the per-export model avoids the 10x phone multiplier that drains Lusha's credits fast.

Compliance matters more than you think

If you sell into European or regulated markets, your data provider's compliance posture directly affects your ability to prospect legally.

Kaspr aligns with GDPR (processing under legitimate interest, Article 6.1(f)) and CCPA, with a notification program that contacts 50,000+ data subjects daily with opt-out information. Data is hosted on OVH in France with AWS France backup.

However, Kaspr discloses no third-party security certifications (no SOC 2, no ISO 27001). For teams selling to enterprise buyers who require vendor security documentation, this gap matters.

Lusha has the deepest compliance stack of the three relative to its size. Nine certifications including ISO 27001, ISO 27701, ISO 27017, ISO 31700, SOC 2 Type II, CSA STAR Level 1, and TRUSTe Certified Responsible AI.

Lusha became the first B2B sales intelligence platform to receive ISO 27701 certification in January 2022. A Trust Kit with all audit copies is downloadable. For compliance-sensitive buyers, Lusha's documentation is a clear differentiator over Kaspr.

ZoomInfo maintains enterprise-grade compliance with ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR, and TRUSTe CCPA validations, all renewed annually.

ZoomInfo is a registered data broker in California and Vermont with a dedicated Trust Center. Its compliance infrastructure is built into the data layer, not bolted on afterward.

For regulated industries (financial services, healthcare, government), ZoomInfo's compliance depth matches the requirements.

Integration ecosystems reflect each tool's ambition

Kaspr integrates with nine tools: HubSpot, Salesforce, Pipedrive, Zoho CRM, Lemlist, Brevo, Aircall, Ringover, and Zapier.

Source: Kaspr

All integrations except Zapier are available on the free plan. Data flows one direction (Kaspr to destination). No webhook support, no Make/Integromat connector.

The API exists but is available only upon request at lower tiers, with rate limits of 20 requests/hour on Starter. This is an integration set for individual contributors, not engineering teams.

Lusha offers broader coverage: native CRM integrations with Salesforce, HubSpot, Pipedrive, Zoho, Bullhorn, monday CRM, Outreach, Salesloft, and MS Dynamics. Automation connectors span Make, n8n, Zapier, Workato, Pipedream, and Albato, plus a Google Sheets add-on.

Source: Lusha

The API supports enrichment, prospecting, signals, lookalikes, and real-time webhooks at 25 requests/second.

Lusha also has an MCP server for feeding verified data into AI tools like Claude and ChatGPT. CRM integrations remain one-way (Lusha pushes out, no bidirectional sync).

For teams building custom agents or workflows, ZoomInfo's integration infrastructure is the most extensible of the three.

Who each tool is designed for

The overlap between Kaspr and Lusha is real, but the fit depends on your team's size, geography, and ambition.

Kaspr is built for individual contributors and small-to-medium-sized sales or recruitment teams prospecting on LinkedIn in European markets. SDRs who live in Sales Navigator and need direct-dial numbers without breaking their workflow.

Recruiters using LinkedIn Recruiter Lite who need candidate contact details. Founders who need to start prospecting on day one without a procurement cycle.

Kaspr is not built for teams needing high-volume enrichment (credit caps limit scale), North American or APAC-focused prospecting (European data is the strength), or enterprise-grade compliance documentation (no third-party security certifications disclosed).

Lusha serves a broader range. Sales teams at B2B technology, staffing, and professional services companies where outbound is the primary growth channel.

Companies expanding into EMEA or APAC where competitors' coverage is weaker. SMB and mid-market teams that want fast setup and transparent pricing. Operatix's 200 SDRs doubled their meetings using Lusha.

Lusha is not built for teams needing conversation intelligence (Gong and Chorus are more mature), teams embedded in a multi-channel engagement platform, or organizations with no outbound motion.

ZoomInfo targets enterprise and upper mid-market organizations. Named customers include Adobe, Snowflake, PayPal, Deloitte, and JPMorgan. 1,921 customers spend $100K+ annually.

ZoomInfo serves sales teams (prospecting and deal execution via GTM Workspace), marketing teams (ABM and demand gen via GTM Studio), and RevOps teams (data quality, routing, and workflow automation).

ZoomInfo is not built for B2C companies or organizations with no outbound or data enrichment needs.

Kaspr and Lusha are good tools for the specific problems they solve. Kaspr excels at European LinkedIn enrichment with minimal friction. Lusha adds signals and sequencing to a broader contact database.

But both are contact data tools that hand off to other systems for execution.

ZoomInfo is built on a different premise: that the value isn't in the data alone, but in the intelligence layer connecting your data, your conversations, your signals, and your outcomes so that every GTM motion draws on the full context of why deals move.

With the GTM Context Graph powering AI agents, multi-channel orchestration, and access through any tool, ZoomInfo provides the infrastructure that contact data tools eventually point toward.

The question isn't just which tool has the contacts you need today. It's whether your platform can grow with your go-to-market motion tomorrow.
