Kaspr vs. Waalaxy (vs. ZoomInfo): How Do They Compare in 2026?

Choosing between Kaspr and Waalaxy for LinkedIn prospecting comes down to a few honest questions:

• Do you need contact data (phone numbers and emails), automated outreach sequences, or both?

• Is your prospecting focused on European markets, or do you sell globally?

• Are you an individual rep who needs a quick data tool, or a team that needs coordinated multi-channel campaigns?

• How important is it that your tool provides buying signals and account intelligence, not just contact records?

• Do you want a point solution for one step of prospecting, or a platform that handles the full go-to-market motion?

In short, here's what we recommend:

Kaspr serves individual sales reps and small teams who prospect on LinkedIn and need European phone numbers and emails fast. Its Chrome Extension pulls contact data from LinkedIn profiles, search results, and Sales Navigator lists, drawing from 200M+ European B2B contacts across 120+ data sources.

It offers a permanent free plan, unlimited B2B emails on paid tiers, and one-click CRM export. The tradeoffs: no outreach automation, limited non-European coverage, and phone credit caps that slow you down at volume.

Waalaxy serves sales reps and founders who want to automate LinkedIn outreach end-to-end. It combines multichannel sequences with a built-in Email Finder and AI message writer. With 99+ pre-built campaign sequences and 150,000+ users, Waalaxy makes LinkedIn outreach accessible to non-technical teams.

But it runs as a Chrome extension (requiring an open browser), caps LinkedIn invitations at 800 per month, and its contact data covers only email addresses, with no direct-dial phone numbers.

Both tools solve pieces of the LinkedIn prospecting puzzle. Kaspr finds the contact data. Waalaxy automates the outreach. But neither tells you which accounts are worth pursuing, why they're in-market right now, or how to coordinate your approach across the full buying committee. That's a different capability entirely.

ZoomInfo is an AI-powered go-to-market platform built on a B2B data foundation: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. Its GTM Context Graph processes 1.5B + data points daily, unifying this data with your CRM records, conversation transcripts, and behavioral signals to reveal the full context of your accounts.

That context gives AI the fuel to show not just what happened, but why it happened and which actions to take next. Sellers work from the GTM Workspace, where AI agents handle account research, draft personalized outreach, and surface next-best actions. Marketers and RevOps teams build and activate plays in GTM Studio.

For teams that build their own tools, APIs and MCP deliver the same intelligence into any application.

Kaspr vs. Waalaxy vs. ZoomInfo at a glance

Contact data vs. outreach automation: They solve different problems

The first thing to understand about Kaspr and Waalaxy is that they do different things, despite both being LinkedIn Chrome extensions built in France.

Kaspr finds contact information. You browse a LinkedIn profile, click the Kaspr widget, and it reveals phone numbers and email addresses from its 120+ verified data sources. You can bulk-enrich entire LinkedIn search lists, push contacts to your CRM, and move on to outreach in whatever tool you prefer. Kaspr does not send messages, automate sequences, or manage conversations. It's a data extraction tool.

Waalaxy automates outreach. You import prospects from a LinkedIn search, pick a pre-built campaign sequence, and Waalaxy sends connection requests, follow-up messages, and cold emails on autopilot. It finds email addresses through its waterfall enrichment across 20+ data sources, but it does not provide phone numbers. The value is in the automation engine, not the data.

Source: Waalaxy Email Finder

This distinction matters because many buyers searching "Kaspr vs. Waalaxy" assume the tools are interchangeable. They're not.

Kaspr gives you the contact data to start conversations. Waalaxy runs the conversations for you on LinkedIn. Some teams need both. Some need one or the other. And some need neither, because both tools operate at the contact-and-message level without telling you whether the contact is worth reaching in the first place.ZoomInfo operates at a different level than both. It doesn’t start with a LinkedIn profile or a message sequence. It starts with identifying which accounts are actually worth your time. Instead of pulling a contact from a search or automating outreach to a list, ZoomInfo surfaces in-market accounts, maps the full buying committee, and provides verified contact data alongside intent signals and company context. The result is a different workflow: you don’t just find people or message them—you prioritize the right accounts first, then engage them with context.

European data depth: Kaspr's strongest card

Kaspr was founded in Paris in 2018 to fill a gap in the French B2B data market, and European coverage remains its defining advantage. The platform claims 200M+ European contacts with hubs in France, the UK, and Spain.

Since its acquisition by Cognism in April 2022, Kaspr's database has expanded. Cognism, itself a B2B data provider and direct ZoomInfo competitor, merged its data into Kaspr, providing "nearly 30% more mobile coverage in key markets". Worth noting: Kaspr's data pipeline now runs on Cognism's infrastructure, which means its roadmap and data investments follow Cognism's competitive priorities.

Waalaxy takes a different approach. It doesn't maintain a proprietary contact database. Its Email Finder queries 20+ premium sources sequentially until it locates a verified email address. This waterfall method claims a 61%+ email match rate and less than 1% bounce rate. But there are no phone numbers. If your outreach depends on cold calls, Waalaxy cannot help.

ZoomInfo operates at a different scale. With 500M contacts and 100M companies globally, plus 135M+ verified phone numbers and 200M+ verified business email addresses, the coverage isn't limited to one continent. ZoomInfo expanded European mobile coverage by 1.8 million numbers across six European markets in 2025 alone.

A multi-source verification pipeline backed by 300+ human researchers maintains up to 95% accuracy on first-party data. In a Fortune 500 competitive RFP analyzing 25 million contacts across vendors, the independent consultant concluded that "no other competitor came even close."

Vensure scaled prospecting with ZoomInfo's data. As Vice President of Revenue Operations William Kenimer put it: "ZoomInfo gives us the information we need to execute. We don't have to go through and spend our time digging. It's already there, so we can be three steps ahead." (Vensure case study)

Outreach automation: Waalaxy's territory

Waalaxy's core value is turning LinkedIn into an automated outreach channel. The workflow is straightforward: import prospects from a LinkedIn search, select one of 99+ pre-built sequences, let Waami AI draft the message, and launch.

Waalaxy handles connection requests, follow-up messages, profile visits, and email touchpoints with human-like delays to stay within LinkedIn's limits. The multichannel capability is where Waalaxy pulls ahead of LinkedIn-only tools.

Source: Waalaxy Follow Up

On the Business plan ($69/user/month), users can combine LinkedIn sequences with cold email follow-ups. When a LinkedIn connection doesn't respond, the Email Finder locates their professional email and Waalaxy re-engages via email, all within the same campaign. This LinkedIn-then-email flow reportedly achieves higher response rates than either channel alone.

Kaspr has no outreach automation. It enriches data and pushes it to CRM or outreach tools like Lemlist and Aircall, but users must manage a separate multi-tool stack for outreach.

ZoomInfo approaches outreach differently. Rather than automating LinkedIn actions through a browser extension, ZoomInfo's GTM Workspace uses AI agents to draft personalized outreach based on the full context of an account: CRM history, conversation transcripts, intent signals, and company news. The Salesloft partnership connects ZoomInfo's buyer data and signals directly into multi-touch, multi-channel sequences.

Source: ZoomInfo with Salesloft

The difference: outreach informed by intelligence, not just contact data. An AI-drafted follow-up that addresses the specific concern a CFO raised on the last call is a different thing from a templated LinkedIn message with a first-name variable.

Seismic attributed 39% of active pipeline to opportunities identified or influenced by ZoomInfo signals, with 54% productivity gains. Chief Business Officer Toby Carrington noted: "That combination of our internal CRM data, external signals, and AI that's given all that context has helped us craft very specific account- and persona-based messages." (Seismic case study)

The intelligence gap neither point solution fills

Both Kaspr and Waalaxy operate at the contact level. Kaspr finds a phone number. Waalaxy sends a LinkedIn message. Neither answers a more basic question: is this the right person at the right account at the right time?

Kaspr's Enterprise plan includes intent data, but it's unavailable to the majority of users on Starter or Business plans. Waalaxy offers no intent, no company-level filtering, no technographic data, and no way to identify which accounts are researching solutions. Users of both tools prospect based on job title and company name, without knowing whether the prospect is even in a buying cycle.

ZoomInfo's GTM Context Graph processes 1.5B + data points daily, fusing third-party intelligence with a customer's CRM records, conversation transcripts, and behavioral signals. Buyer Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ keyword-to-device pairings sourced monthly.

WebSights resolves anonymous website traffic to companies and individual contacts. Guided Intent identifies topics historically correlated with deal success rather than requiring manual topic selection.

Source: ZoomInfo Intent Data

The practical difference: a Kaspr or Waalaxy user might reach out to 500 contacts based on a LinkedIn search filter and get a handful of meetings.

A ZoomInfo user can identify which of those 500 show active research behavior, prioritize by account fit score, and enter each conversation knowing the prospect's tech stack, recent funding activity, and position in the org chart. That context changes both the efficiency and quality of outreach.

Levanta used ZoomInfo's intent data to prioritize high-value opportunities. CEO Ian Brodie described the shift: "ZoomInfo's not just a contact data company anymore. They've built a full system of execution. GTM Intelligence actually works the list, writes the outreach, triggers the play, and helps drive predictable growth." (Levanta case study)

Pricing: What you get for what you pay

Kaspr uses a credit-based model with four credit types (B2B email, phone, direct email, export). The Free plan is permanent with 15 B2B emails and 5 phone credits per month. Starter ($49/user/month annual) unlocks unlimited B2B emails but only 1,200 phone credits per year (100 per month).

Business ($79/user/month annual) provides 2,400 phone credits per year. The "unlimited" B2B emails carry a fair-use cap of 10,000 per account per month. Additional phone credits start at $91 for 2,500 credits annually.

The credit caps are the hidden cost of Kaspr. A high-volume SDR who burns through 100 phone credits in two weeks faces a choice: buy add-ons or wait until next month. Export credits are also capped (12,000/year on Starter, 30,000 on Business), and each export is charged every time a lead is exported, not just the first time.

Waalaxy uses a tiered per-seat model. The Free plan ($0) allows 80 LinkedIn invitations per month with basic automation. Pro ($19/month) bumps invitations to 300 and adds CRM sync and CSV import. Advanced ($39/month) is the most popular, with 800 invitations and live chat support.

Business ($69/month) is the only plan with cold email sequences and includes 500 Email Finder credits per month (versus 25 on lower plans). The LinkedIn Inbox add-on costs an additional €20/month. Quarterly billing saves 20%, yearly saves 50%.

Waalaxy's pricing means the true cost of multichannel outreach is higher than it appears. A user wanting LinkedIn automation plus cold email plus inbox management pays $69 + $20 = $89/month before any email finder credit add-ons.

ZoomInfo uses custom-quoted pricing with seat-and-credit-based tiers, reflecting its enterprise positioning. ZoomInfo Lite is a permanent free tier with access to the B2B database, 10 monthly export credits, the Chrome extension, and HubSpot integration. A 7-day free trial provides broader access to platform features.

ZoomInfo costs more than either Kaspr or Waalaxy. That's by design. The comparison isn't price per seat; it's return on investment.

Teams using ZoomInfo report measurable outcomes: Snowflake saw 200% higher conversion rates on accounts monitored using ZoomInfo-powered scores. Thomson Reuters increased closed-won deals by 40%. These results reflect what happens when prospecting runs on intelligence rather than volume.

LinkedIn account safety: The elephant in the room

Both Kaspr and Waalaxy operate as Chrome extensions that interact with LinkedIn, and both face the reality that LinkedIn restricts automation.

Waalaxy carries the higher risk because it automates actions on LinkedIn: sending connection requests, messages, and profile visits. Waalaxy implements safety measures, including randomized daily action quotas (80 to 100 connection requests per day, random 2 to 3 minute delays between actions) and an abnormal-behavior alert system that pauses campaigns for 48 hours if limits are at risk.

Source: Waalaxy Daily Quotas

The extension also reportedly intercepts LinkedIn's detection script to avoid detection. Despite these safeguards, multiple third-party reviewers report LinkedIn account restrictions, and the browser-must-stay-open requirement makes campaigns less reliable than cloud-based alternatives.

Kaspr takes a lighter approach. Its extension does not scrape LinkedIn data. It reads the profile you're viewing and appends contact information from Kaspr's own database.

Kaspr includes a setting to hide the widget to reduce detection risk. Bulk enrichment automations are described as less likely to trigger flags than manual profile-by-profile enrichment, but the risk of LinkedIn enforcing its terms against any Chrome extension-based tool remains.

Source: Kaspr Hide Widget

ZoomInfo sidesteps this issue entirely. Its prospecting tools operate independently of LinkedIn's interface. Contact data, intent signals, and outreach happen within ZoomInfo's platform, CRM integrations, or API-connected tools, with no interaction with LinkedIn's detection systems. For teams where LinkedIn account safety is a concern, this architectural difference matters.

Team collaboration and scaling

As individual sales tools, both Kaspr and Waalaxy work fine. Problems emerge when teams try to scale.

Kaspr offers pooled credits across a workspace on paid plans, team usage reports (Starter+), and custom member permissions (Business+). The Organization plan requires a minimum of 5 users and is annual-only, with a dedicated account manager. But with a 35+person team, Kaspr's support capacity and feature development pace are constrained compared to larger platforms.

Waalaxy has invested more in team features. The team dashboard provides one-click access to member accounts, anti-duplicate prospect import to prevent the same contact from being contacted twice, shared lead lists, and the ability to share a Sales Navigator license across the team. Support ranges from a 48-hour email response on Pro to live chat on Advanced and Business plans.

ZoomInfo is built for enterprise teams. GTM Workspace connects to Salesforce, HubSpot, and Microsoft Dynamics natively, so sellers work from one surface without switching between tools. GTM Studio lets RevOps and marketing teams build audience segments, launch plays, and route leads, all coordinated through the same intelligence layer.

BDO Canada activated ZoomInfo data within their internal systems. Senior Marketing Intelligence Analyst Jerry Wilson noted: "The plug-and-play aspect of the API means I can integrate it very easily into any process and get information at a moment's notice." The result: an 87% reduction in time spent on internal data dashboard updates. (BDO Canada case study)

Compliance and security posture

For regulated industries and enterprise procurement, security certifications matter.

Kaspr processes data under GDPR legitimate interest (Article 6.1(f)) and notifies 50,000+ contacts per day as part of its opt-out process. Data is hosted on OVH and AWS (France). No third-party security certifications (SOC 2, ISO 27001) are disclosed on any official Kaspr pages. SSO and enterprise-level compliance features are Enterprise-only.

Source: Kaspr Compliance

Waalaxy states compliance with GDPR and CCPA. Payment processing is handled by Stripe. Beyond these basics, Waalaxy does not publish details on encryption standards, security certifications, or a public trust center.

ZoomInfo maintains a full certification stack, all renewed annually: ISO 27001, ISO 27701, SOC 2 Type II, and TRUSTe GDPR and CCPA validations. It's a registered data broker in California and Vermont and maintains a dedicated Trust Center. For enterprise buyers in regulated industries, this gap between the three platforms is significant.

Kaspr vs. Waalaxy vs. ZoomInfo: Which should you choose?

The right tool depends on where you are in the prospecting maturity curve.

Choose Kaspr if:

• You need European phone numbers and emails from LinkedIn profiles

• You're an individual contributor or small team doing manual outbound

• Speed-to-data matters more than outreach automation

• You already have a separate outreach tool and need a data layer

• LinkedIn is your primary outreach channel and you want to automate it

• You need combined LinkedIn and cold email sequences in one tool

• You're a non-technical user who values simplicity over depth

• Your team is small (under 20 people) and selling B2B

• You're comfortable with the tradeoffs of Chrome extension-based automation

Choose ZoomInfo if:

• You need global contact data, not just European coverage

• Knowing which accounts are in-market matters more than blasting volume

• Your team needs AI-driven account intelligence, not just contact records

• You want a platform that coordinates sales, marketing, and RevOps on shared data

• Security certifications and enterprise compliance are procurement requirements

• You're ready to move from point-solution prospecting to full go-to-market execution

See how ZoomInfo's GTM intelligence transforms prospecting with a free trial.

Kaspr and Waalaxy each solve a narrow but real problem. Kaspr finds European contact data quickly. Waalaxy automates LinkedIn outreach efficiently. But as teams grow and prospecting gets more competitive, the limiting factor isn't finding phone numbers or sending more connection requests. It's knowing which accounts deserve your attention and why.

That intelligence layer, built on data, buying signals, and contextual AI, is what separates volume-based outreach from predictable pipeline generation. ZoomInfo provides that layer.

Kaspr vs. Waalaxy vs. ZoomInfo FAQ

What is the core difference between Kaspr, Waalaxy, and ZoomInfo?

Kaspr is a B2B contact data enrichment tool focused on European phone numbers and emails extracted from LinkedIn profiles. Waalaxy is a LinkedIn outreach automation tool that sends connection requests, follow-up messages, and cold emails in automated sequences.

ZoomInfo is an AI-powered GTM platform with 500M contacts and 100M companies globally, plus buyer intent data, a GTM Context Graph that processes 1.5B + data points daily, and AI-driven execution through GTM Workspace and GTM Studio.

Which platform provides phone numbers?

Kaspr provides phone numbers from its database of 200M+ European B2B contacts across 120+ data sources. ZoomInfo provides 135M+ verified phone numbers and 120M direct-dial numbers globally. Waalaxy does not provide phone numbers. Its Email Finder retrieves professional email addresses only.

Can I use Kaspr and Waalaxy together?

Yes. Some teams use Kaspr for contact data enrichment (especially phone numbers) and Waalaxy for LinkedIn outreach automation. There is no native integration between the two tools. You would need to export contacts from Kaspr and import them into Waalaxy, or use a CRM as the bridge.

Which platform is safest for my LinkedIn account?

ZoomInfo does not interact with LinkedIn's interface at all, so there is no LinkedIn account risk. Kaspr reads profiles and appends data from its own database without automating actions on LinkedIn, carrying lower risk. Waalaxy automates connection requests, messages, and profile visits, which carries the highest risk of LinkedIn detection and account restrictions, despite its built-in safety measures.

How does pricing compare for a team of five?

Kaspr Starter costs $49 per user per month annually ($245/month for five users) with 1,200 phone credits per year per seat. Waalaxy Business costs $69 per user per month ($345/month for five users) for full multichannel features, with 500 email finder credits per month.

ZoomInfo requires a custom quote, though ZoomInfo Lite is a permanent free tier for individuals. ZoomInfo's pricing reflects its enterprise positioning and broader capability set.

Which platform is best for prospecting outside Europe?

ZoomInfo has the strongest global coverage, with 500M contacts and 100M companies worldwide, plus 135M+ verified phone numbers globally.

Kaspr focuses on European data, stating that "Europe is our home and where we provide unmatched data quality." Waalaxy pulls from LinkedIn's global member base for outreach but relies on third-party enrichment sources for emails, with no phone number coverage in any geography.

Does any platform include buyer intent data?

ZoomInfo includes buyer intent as a core capability across its Advanced and Enterprise sales plans, tracking signals from 210 million IP-to-Organization pairings and 6 trillion+ keyword-to-device pairings monthly. Kaspr offers intent data only on its Enterprise plan, which requires custom pricing. Waalaxy does not provide any intent or buying signal data.

Which platform requires the least technical setup?

Waalaxy and Kaspr both install as Chrome extensions and are designed for non-technical users. Waalaxy claims users can be operational in 10 minutes per day. Kaspr customers confirm fast onboarding with no training needed.

ZoomInfo has a broader platform with more capabilities, and its onboarding program runs 30 to 90 days, but it also offers ZoomInfo Lite as a simple free entry point with basic search and export functionality.
