Cognism vs. Kaspr (vs. ZoomInfo): Which B2B Data Platform Fits Your Sales Team in 2026?

If you're comparing Cognism vs. Kaspr, here's something most articles won't tell you upfront: Cognism owns Kaspr. Cognism acquired Kaspr in April 2022, and the two products now share underlying data. They're not competitors. They're siblings built for different buyers.

Cognism targets mid-market and enterprise sales teams that need compliant contact data across Europe and the US. Kaspr targets individual contributors and small teams that prospect on LinkedIn and need phone numbers fast. The real question isn't which one is "better." It's which approach matches where your team is today, and where it's headed.

Here are the questions that actually matter:

• Are you an individual rep prospecting on LinkedIn, or a team that needs a centralized data platform?

• Is your primary market in Europe, or do you need global coverage including the US?

• Do you need just contact data, or do you also need intent signals, buying group intelligence, and AI-powered outreach?

• Is a freemium self-serve tool enough, or do you need enterprise compliance and integrations?

• Do you want a tool that finds phone numbers, or a platform that tells you which accounts to call and why?

In short, here's what we recommend:

Cognism is the right choice for mid-market and enterprise revenue teams that prioritize European data accuracy and GDPR compliance. Its Diamond Data phone-verified mobile numbers deliver a 20% connection rate, 7x the industry standard, and its database spans 440M+ contacts across 100M+ companies. The Sales Companion product adds AI account recommendations and signal-based prospecting. However, Cognism doesn't publish pricing, requires a sales conversation to get started, and lacks built-in sequencing for outreach.

Kaspr is built for individual salespeople and small teams who live in LinkedIn and need contact data without leaving the platform. Its Chrome Extension surfaces phone numbers and emails on LinkedIn profiles, Sales Navigator, Events, and Groups. A free plan with no credit card required makes it easy to test, and paid plans start at $49/user/month. The tradeoff: phone credits are capped (as low as 100/month on Starter), there's no native outreach sequencing, and the platform's strength is concentrated in Europe.

Both Cognism and Kaspr solve the same core problem: getting accurate contact data for outbound prospecting. But they share a limitation. Neither provides intent signals beyond Bombora resale (Cognism) or basic LinkedIn activity (Kaspr), neither offers built-in sales engagement, and neither captures conversation intelligence or tells you why deals in your pipeline are moving or stalling. For teams that need the full picture (not just contact data but the context behind why accounts are worth pursuing) there's a different approach.

ZoomInfo is an AI 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 unifies your CRM records, conversation transcripts, and behavioral signals with the 1.5B+ data points ZoomInfo processes daily. This captures why deals move or stall, so 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, RevOps, and GTM engineers, or APIs and MCP in any front-end. In a Fortune 500 competitive RFP analyzing 25 million contacts, the independent consultant concluded that "no other competitor came even close."

Cognism vs. Kaspr vs. ZoomInfo at a glance

Cognism and Kaspr are connected, and that matters

Before comparing features, you need to understand the relationship between these two products.

Cognism acquired Kaspr in April 2022 for an undisclosed sum.

At the time, Kaspr had roughly 1,500 customers, 50,000 users, and a team of 14. Cognism's CEO said the acquisition would enable a product-led growth model and freemium offering that Cognism's enterprise sales motion lacked. Cognism also said it would merge Kaspr's data into Cognism products, adding nearly 30% more mobile coverage in key markets.

Today, Kaspr's help center confirms that they share data between their data sets. Kaspr still maintains its own brand, product, and pricing, and even runs a Kaspr vs. Cognism comparison page. But under the hood, the data backbone is shared.

This means the choice between Cognism and Kaspr is less about data quality and more about workflow, team size, and budget. Cognism is the enterprise product with broader capabilities. Kaspr is the self-serve entry point for smaller teams. They sit on different floors of the same building.

The real competitive comparison emerges when you introduce a third category: platforms that go beyond contact data. While Cognism and Kaspr focus primarily on delivering B2B contact information, platforms like ZoomInfo position themselves as broader go-to-market intelligence systems that combine contact data with intent signals, AI workflows, and sales execution tools. Understanding that difference helps frame the rest of the comparison.

European data is strong for both, but ZoomInfo leads globally

All three platforms claim strong European contact data. The difference is scale and independent validation.

Cognism built its reputation on European data depth.

The company claims 90% coverage of director-level contacts in Europe and the US and screens against DNC registries in 15 countries including the UK, Germany, France, Spain, and (uniquely) Italy. Lead Forensics reported that Cognism converted 60% better than a US competitor for EU data. For teams selling primarily into Europe, this coverage is a genuine advantage.

Kaspr inherits Cognism's European strength and adds a LinkedIn-native layer.

The company positions itself as "Europe's trusted data provider" with 200M+ European B2B contacts from 120+ verified sources. Customer stories confirm this focus: Cloud Direct's SDR Manager switched because a previous provider was pulling American numbers for UK-based contacts. Kaspr's own sales page states it plainly: "Europe is our home and where we provide unmatched data quality."

ZoomInfo operates at a different scale.

The database spans 500M contacts and 100M companies globally, with 135M+ verified phone numbers and 200M+ verified business emails. International coverage includes 34M+ company profiles outside North America, 200M+ professional profiles outside NA, and 45M+ mobile numbers outside NA.

In 2025, ZoomInfo expanded international mobile coverage by 1.8 million numbers across six European markets. Data quality is independently validated: ZoomInfo is a Leader in the Gartner Magic Quadrant for ABM Platforms, the only vendor in the Customers' Choice quadrant on Gartner Peer Insights, and holds 133 No. 1 rankings on G2.

If your team sells exclusively into European markets, Cognism's DNC registry coverage across 15 countries is a specific compliance advantage. If your team sells across regions, ZoomInfo's global scale and independent validation give it a broader foundation.

Phone-verified data: Cognism's Diamond Data vs. ZoomInfo's verification pipeline

Phone numbers that don't connect waste time and damage rep morale. Both Cognism and ZoomInfo invest in phone verification, but their approaches differ.

Cognism's Diamond Data is a set of 10M+ phone-verified mobile numbers that have been called by a human and confirmed to belong to the correct person.

These numbers show a 20% connection rate, 7x the industry standard, and an independent study found they are 3x more likely to connect than non-verified numbers. Cognism also offers Diamonds on Demand, a service that will phone-verify a specific contact within 48 hours on request. Diamond Data is included in the Elevate tier and available as a paid add-on for the Grow tier.

Source: Cognism

Kaspr doesn't offer a similar human verification process.

Contact data comes from 120+ verified providers and is updated in real time when a user requests it, with email re-validation every two months. The widget previews available data before a credit is spent, which customers appreciate, but there's no equivalent to Diamond Data's manual confirmation.

ZoomInfo maintains 135M+ verified phone numbers and 120M direct-dial phone numbers through a multi-source verification pipeline that includes automated ML scanning of 28 million site domains daily, 300+ human researchers, and a community of 200,000+ ZoomInfo Lite users who share data back. First-party data reaches up to 95% accuracy.

The scale difference is clear: ZoomInfo's 120M direct dials represent 12x the volume of Cognism's Diamond Data set (10M+).

Cognism's human phone-verification process is a genuine differentiator for the contacts it covers. But the 10M+ Diamond Data pool is a fraction of the global contact universe. Teams needing verified phone numbers at scale, particularly outside Europe, will find ZoomInfo's verification infrastructure covers more ground.

LinkedIn prospecting: where Kaspr excels

If your reps spend most of their day in LinkedIn and Sales Navigator, Kaspr offers the smoothest workflow of the three.

The Kaspr Chrome Extension overlays on LinkedIn profiles, showing a preview of available contact data before you spend a credit. It works across profile pages, search results, Sales Navigator lists, Recruiter Lite, Events attendees, Group members, and post engagers. Bulk enrichment automations can process up to 2,500 contacts per Sales Navigator search without manual profile-by-profile work. Credits are only spent when required data points are found.

Customer feedback confirms the speed: one user noted "I didn't have to be trained on how to use Kaspr", and Visibly HQ booked six discovery calls within the first two weeks.

Cognism also has a Chrome Extension that works on LinkedIn, Sales Navigator, and corporate websites.

But Cognism's extension is part of a broader platform (Sales Companion) and serves as one element of a multi-channel prospecting workflow, not the primary interface. It surfaces AI-recommended leads, signal data, and one-click account research alongside the contact data.

ZoomInfo offers the ReachOut Chrome Extension for LinkedIn and web browsing, plus a mobile app.

Like Cognism, ZoomInfo treats the extension as one access point into a larger platform. The primary experience is GTM Workspace, where AI agents surface prioritized accounts, draft outreach, and update CRM without toggling between tools.

For reps who want the simplest path from "I found this person on LinkedIn" to "I have their phone number," Kaspr is the most direct route. For teams that need LinkedIn enrichment as part of a broader intelligence and execution workflow, Cognism and ZoomInfo offer more context around the data.

Beyond contact data: intent signals and contextual intelligence

Finding contact data is the starting point. Knowing which contacts to prioritize, and why, is where the real value lies.

Cognism offers six categories of signal data: hiring trends, funding alerts, technographics (covering 20,000+ technologies), job changes, intent data, and M&A activity.

Intent data is powered by Bombora Company Surge and available only on the Elevate tier. Users can select up to 12 intent topics from over 11,000 options. This is useful, but Bombora is a third-party signal that Cognism resells. Other platforms, including ZoomInfo, also access Bombora data.

Kaspr offers no intent data or signal intelligence on its standard plans. The Enterprise plan lists intent data as a feature, but details are limited and pricing requires a sales conversation.

ZoomInfo runs a proprietary intent engine that tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly.

Guided Intent, exclusive to ZoomInfo, identifies topics historically correlated with deal success rather than requiring manual topic selection. This proprietary signal layer is part of the reason Forrester named ZoomInfo a Leader in Intent Data Providers for B2B, Q1 2025, with the highest possible scores across eight criteria.

But the deeper difference is architectural.

ZoomInfo's GTM Context Graph doesn't just collect intent signals. It fuses them with your CRM records, conversation intelligence from calls (via Chorus), email interactions, and behavioral data to build an intelligence layer that captures why deals move or stall.

A CRM records that a deal stage changed. The GTM Context Graph captures that the CFO joined the last call and asked about ROI, that three new VPs were just hired, and that the company is researching a competitor. That intelligence flows into the AI-drafted outreach, the account prioritization, and the forecast.

Neither Cognism nor Kaspr offers conversation intelligence, first-party data unification, or deal-level insight. They provide data to feed into your existing tools. ZoomInfo provides the intelligence layer that connects data to decisions.

Sales engagement and outreach execution

Finding the right contact is one job. Reaching them is another. The three platforms take different approaches to outreach execution.

Kaspr has no built-in outreach capability.

It enriches data and pushes it to external tools: Lemlist for email sequences, Aircall and Ringover for calling, plus CRM integrations with HubSpot, Salesforce, Pipedrive, and Zoho. The workflow: find the contact on LinkedIn, reveal data via extension, export to your outreach tool.

Cognism also lacks native sequencing.

Sales Companion handles research and data enrichment, but outreach execution relies on integrations with Outreach and Salesloft. The platform tells reps who to call and provides the data. How they call is handled by other tools.

Source: Cognism

ZoomInfo includes native execution.

GTM Workspace gives sellers AI-drafted outreach generated from full account context, an Action Feed with pre-drafted actions on every buying signal, and native CRM integration so reps can update records without leaving the page.

For teams that prefer a dedicated sales engagement platform, the Salesloft partnership connects ZoomInfo buying signals to Salesloft's sequencing engine. GTM Studio handles marketing and GTM orchestration, including multi-channel campaigns across email, calls, ads, and direct mail triggered by buyer behavior.

The practical impact: with Cognism or Kaspr, your team needs at least one additional tool for outreach execution, plus the integrations to connect them. With ZoomInfo, intelligence and execution live in the same platform.

Pricing transparency varies significantly

Kaspr is the most transparent. Four published tiers:

• Free: $0. Includes 5 phone credits per month and 10 export credits total.

• Starter: $49 per user/month (annual). Includes 1,200 phone credits per year and 12,000 export credits per year.

• Business: $79 per user/month (annual). Includes 2,400 phone credits per year and 30,000 export credits per year.

• Enterprise: Custom pricing (minimum 5 users). Includes 24,000 phone credits per year and 120,000 export credits per year.

All paid plans include unlimited B2B email credits, though the Terms disclose a 10,000/month fair-use cap per account. Add-on phone credits are available: 2,500 for $91/year ($0.036 each) up to 50,000 for $1,133/year ($0.023 each). The free plan requires no credit card and is permanent, not a trial.

Cognism publishes no prices.

Two named tiers (Grow and Elevate) are described on the pricing page, but every field reads "Contact us." The Grow tier includes business emails and mobile numbers; the Elevate tier adds Diamond Data, intent data, technographics, and expanded export limits. No free plan exists, though Cognism offers a free data sample and a formal Preview evaluation on request.

ZoomInfo also uses custom pricing but offers more entry points.

ZoomInfo Lite is a permanent free tier with 10 monthly export credits, access to the B2B database, the Chrome Extension, and WebSights Lite. A 7-day free trial of the full platform is available with no credit card.

Paid plans are organized into Sales, Marketing, and Chorus product lines, each with three tiers (Professional, Advanced, Enterprise). Credits work on a 1-credit-per-export basis, and searching within ZoomInfo does not consume credits.

For budget-conscious teams, Kaspr's transparent pricing is a clear advantage. For teams evaluating enterprise platforms, both Cognism and ZoomInfo require a conversation, but ZoomInfo's free Lite tier and trial offer a lower-friction evaluation path than Cognism's demo-request-only model.

Compliance and security certifications

For teams in regulated industries or selling into Europe, compliance infrastructure matters.

Cognism holds ISO 27001, ISO 27701, and SOC 2 Type II certifications and screens against 15 DNC registries globally. Data is processed under legitimate interest (GDPR Article 6.1(f)), with a fully notified database and registration as a data broker with the California Attorney General. This is the strongest compliance posture among the three for European-specific DNC coverage.

Kaspr processes data under legitimate interest (GDPR Article 6.1(f)) and notifies 50,000+ contacts per day as part of its opt-out program. Infrastructure is hosted on OVH in France with AWS backup in France. However, no third-party security certifications (SOC 2, ISO 27001) are disclosed on any official Kaspr page. Enterprise features like SSO and advanced compliance controls require the Enterprise plan.

ZoomInfo maintains ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR, and TRUSTe CCPA certifications, all renewed annually. The company is a registered data broker in California and Vermont and maintains a dedicated Trust Center.

Enterprise buyers running formal procurement evaluations will find Cognism and ZoomInfo meet similar certification thresholds. Kaspr's lack of disclosed third-party certifications may present a gap for security-sensitive organizations.

Integration ecosystems reflect different audiences

Kaspr keeps it simple: nine native integrations (HubSpot, Salesforce, Pipedrive, Zoho CRM, Lemlist, Brevo, Aircall, Ringover, Zapier).

All except Zapier are available on the free plan. No webhooks, no Make/Integromat support. The API is available upon request at Starter and Business tiers, with rate limits as low as 20 requests/hour on Starter. This works for small teams but limits technical buyers and automation-heavy workflows.

Cognism integrates natively with Salesforce, HubSpot, Pipedrive, Microsoft Dynamics, Bullhorn, Outreach, Salesloft, and Zapier. A native two-way HubSpot sync launched in February 2026. The REST API supports Search, Enrich, and Redeem endpoints. For enterprise data operations, the DaaS offering delivers to Snowflake, AWS S3, Google Cloud, Databricks, and SFTP.

ZoomInfo has the broadest ecosystem: the App Marketplace lists 120+ partner integrations across CRM, marketing automation, sales engagement, data warehouses, and communications.

The Enterprise API provides full programmatic access, and the MCP server enables any AI agent (including Claude and ChatGPT) to query ZoomInfo data directly. API access is included in all relevant plans. Cloud Partners deliver data into AWS, Google Cloud, Snowflake, and Databricks.

For teams building custom workflows or powering AI agents with B2B data, ZoomInfo's API, MCP, and marketplace breadth are in a different category. Kaspr's integrations cover the basics for small teams. Cognism sits between the two, with solid CRM coverage and a growing API surface.

Cognism and Kaspr do contact data well, particularly for European markets. They're good tools for the specific jobs they were designed for.

But they're data providers.

ZoomInfo is an AI GTM Platform that connects data to context, context to decisions, and decisions to execution. For teams that have outgrown the "find a phone number" workflow and need to understand which accounts to pursue and why, that's the gap ZoomInfo fills.
