Kaspr vs. RocketReach (vs. ZoomInfo): Which B2B Contact Data Platform Fits Your Needs in 2026?

Choosing between Kaspr and RocketReach for your B2B contact data often comes down to five questions:

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

• Do you want a tool that lives inside LinkedIn, or a standalone platform with its own search engine?

• Is a free tier with limited credits enough, or do you need high-volume enrichment and outreach?

• How important are built-in email sequences versus pushing contacts to a separate outreach tool?

• Do you need contact data alone, or do you also need intent signals, conversation intelligence, and AI-driven deal execution in one place?

Here's what we recommend:

Kaspr is built for individual contributors and small sales teams who prospect on LinkedIn and need European contact data fast. Its Chrome Extension surfaces phone numbers and emails on LinkedIn profiles, Sales Navigator lists, events, and post engagers, drawing from 200M+ European B2B contacts across 120+ verified data sources. The free tier requires no credit card, and paid plans start at $49/user/month. But Kaspr has no native email sequencing, caps phone credits at modest volumes, and covers non-European data less thoroughly than its core markets.

RocketReach serves a broader audience across sales, marketing, recruiting, and healthcare with 700M+ professional profiles and 60M companies worldwide. Its multi-step Sequences (launched February 2026) and Autopilot automation bring prospecting and outreach under one roof, while Intent Data (powered by Intentsify) identifies in-market accounts. RocketReach is bootstrapped and profitable, keeping prices competitive. The trade-off: its engagement features are still maturing, and advanced capabilities like intent data and healthcare contacts require higher tiers.

Both platforms solve the core problem of finding verified contact data. But contact data is only the starting point of a go-to-market motion. For teams that need the data, the intelligence behind it, and the ability to act on it from one platform, there's a third option.

ZoomInfo is an AI-powered go-to-market platform built on a large B2B data foundation: 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses. That data fuels ZoomInfo's GTM Context Graph, an intelligence layer that processes 1.5B+ data points daily by combining your CRM records, conversation transcripts, and behavioral signals with ZoomInfo's third-party intelligence to reveal not just what's happening in a deal, but why. Sellers work from GTM Workspace, where AI agents handle account research, outreach drafting, and CRM updates. Marketers and RevOps teams build plays in GTM Studio using natural language. And for teams that build their own tools, APIs and MCP expose the same intelligence to any AI agent or application.

If you need more than contact data, and want intelligence that tells you who to reach, when to engage, and what to say, see how ZoomInfo works.

Kaspr vs. RocketReach vs. ZoomInfo at a glance

Relationship to ZoomInfo: both are contact data tools; ZoomInfo is a GTM platform

Before digging into the comparison, it helps to understand what each tool was designed to do.

Kaspr and RocketReach are contact data platforms. They help you find verified emails and phone numbers for the people you want to reach. Kaspr does this through a LinkedIn extension; RocketReach through a web-based search engine with a browser extension alongside it. Both do their core job well.

ZoomInfo is broader. It includes a contact and company database larger than either, built on verification infrastructure that has been externally validated (a Fortune 500 competitive RFP concluded "no other competitor came even close"). But it also includes buyer intent signals, conversation intelligence, website visitor identification, AI-powered deal execution, and multi-channel orchestration.

Teams that only need contact lookups can get real value from Kaspr or RocketReach. Teams that need to build a full go-to-market motion around that data will find ZoomInfo covers ground the other two don't attempt.

Data coverage: European depth vs. global breadth

Kaspr was founded in Paris in 2018 to fill a gap in European B2B data.

After its acquisition by Cognism in 2022, the database grew through the Cognism data merge. Today, Kaspr claims 200M+ European B2B contacts sourced from 120+ verified providers, with particular depth in France, the UK, Germany, and Spain.

For teams prospecting in European markets, this specialization matters. Customer stories confirm the edge: Cloud Direct's SDR Manager noted that a previous provider's phone numbers were "poor quality, pulling American numbers when it was a UK-based person", a problem Kaspr resolved.

RocketReach takes a global approach: 700M+ professional profiles across 100+ countries, with 500M emails and phones verified per quarter.

The database is not static; every lookup triggers real-time email prediction and verification rather than serving cached results. RocketReach also maintains specialized verticals, including 6.3M+ healthcare contacts with NPI data, a niche neither Kaspr nor most B2B databases cover well.

ZoomInfo operates at the largest scale: 500M contacts across 100M companies, with 135M+ verified phone numbers (including 120M direct dials).

Global coverage includes 34M+ company profiles and 200M+ professional profiles outside North America, plus 45M+ mobile numbers outside NA. In 2025, ZoomInfo expanded international mobile coverage by 1.8 million numbers across six European markets.

The verification pipeline combines automated ML scanning of 28 million site domains daily, third-party partner data, a community of 200,000+ ZoomInfo Lite users who share data back, and 300+ human researchers, reaching up to 95% accuracy on first-party data.

The practical question: where are your prospects?

If they're in Europe, Kaspr's focused depth is a real advantage, especially for direct-dial mobile numbers. If they're spread globally, RocketReach covers more geography at a competitive price.

If you need the largest verified dataset paired with the infrastructure to keep it accurate at scale, ZoomInfo is where enterprise teams land, and that same data feeds the intelligence and execution layers that set it apart from contact-only tools.

Workflow design: LinkedIn-native vs. standalone search vs. full platform

These three products assume different workflows, and that assumption shapes everything.

Kaspr lives inside LinkedIn. The Chrome Extension appears as a widget on LinkedIn profiles, search results, Sales Navigator lists, events, groups, and post engagers. You browse LinkedIn, see a prospect, click to reveal their contact data, and push it to your CRM.

Source: Kaspr

Kaspr also supports bulk enrichment automations that process up to 2,500 contacts per Sales Navigator search, with credit-conditional logic so credits are spent only when the required data is found. For salespeople who already live in LinkedIn, this removes the need to switch tools.

The limitation: Kaspr depends on LinkedIn. Without a LinkedIn account (and at least 20 connections), you can't use it. There's no independent company search, no org chart browsing, and no way to find contacts outside the LinkedIn graph.

RocketReach is a standalone search platform. You search by name, company, title, industry, skills, technologies, or any of 100+ filters to build prospect lists. The Chrome and Edge extension (with 300K+ users) supplements this by surfacing contact data on any website, not just LinkedIn. CSV upload enables batch enrichment.

Source: RocketReach

Saved Searches auto-generate new leads as the database updates. RocketReach doesn't require LinkedIn, giving it more flexibility in how you discover prospects.

ZoomInfo is a full GTM platform. Contact and company search is one capability among many. Contact & Company Search uses 300+ company attributes for filtering, and includes department org charts with decision-makers' direct dials.

But the search feeds into a broader system: Buyer Intent identifies accounts researching solutions, WebSights reveals which companies visit your site, Chorus captures and analyzes sales conversations, and GTM Workspace brings it all together in an AI-powered execution environment. For teams that want one platform connecting data to action, ZoomInfo eliminates the need to stitch multiple tools together.

Outreach capabilities: none vs. growing vs. multi-channel

This is where the three tools diverge.

Kaspr has no native outreach. It enriches contacts and pushes them to CRMs (HubSpot, Salesforce, Pipedrive, Zoho) or outreach tools (Lemlist, Aircall, Ringover). If you need email sequences or calling cadences, you'll need a separate tool. For small teams that already have an outreach stack, this works. For teams starting from scratch, it means an additional subscription and another tool to manage.

RocketReach added email sequences in February 2026. Multi-step Sequences support up to 50 email steps with configurable delays, an AI Assist writer for generating templates, timezone-aware sending, and automatic stops on reply or bounce.

Source: RocketReach

Autopilot automates the full loop: search, lookup, and email send on daily, weekly, or monthly schedules. This is a meaningful step toward a combined prospecting-and-outreach workflow. But Sequences launched recently, covers email only (no phone or LinkedIn channels), and is less mature than dedicated engagement platforms like Outreach or Salesloft.

Source: RocketReach

ZoomInfo offers multi-channel engagement through its Salesloft partnership. ZoomInfo's buyer signals sync into Salesloft Rhythm for AI-prioritized multi-touch sequences across phone and email.

ZoomInfo's native Workflow Tools automate activities based on buying signals, and GTM Workspace includes AI agents that draft personalized outreach from full account context.

For marketing teams, GTM Studio orchestrates plays across email, display ads (via a native DSP), LinkedIn, Meta, and Connected TV. The result: signal to action in one platform, with no manual export step.

Intent data and buying signals

Knowing who to reach is one problem. Knowing when they're ready to buy is another.

Kaspr offers intent data on its Enterprise plan only, which requires custom pricing and a minimum of 5 users. For Kaspr users on Free, Starter, or Business plans, intent data is not available.

The LinkedIn surfaces Kaspr operates on (events, groups, post engagers) offer a lightweight form of signal detection by identifying prospects engaging with relevant content, but these are behavioral proxies, not purchase-intent signals.

RocketReach launched Intent Data in February 2024, powered by Intentsify (named a Leader in the Forrester Wave: Intent Providers for B2B, Q1 2025). Coverage spans 35,000+ topics with 1.1 trillion signals monthly from 460,000+ B2B content sites.

Source: RocketReach

Intent signals appear inline in search results, letting you filter for accounts that are actively researching. The limitation: Intent Data is only available on the Ultimate plan.

ZoomInfo runs its own intent infrastructure at a different scale. ZoomInfo Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ new keyword-to-device pairings sourced monthly.

Guided Intent, exclusive to ZoomInfo, automatically identifies topics historically correlated with deal success rather than requiring manual topic selection.

Intent signals combine with WebSights (website visitor identification), Chorus conversation signals, and CRM data inside the GTM Context Graph, creating a multi-layered view of buyer readiness that neither Kaspr nor RocketReach can replicate.

Forrester named ZoomInfo a Leader in Intent Data Providers for B2B (Q1 2025), with the highest possible scores across eight criteria.

Pricing: free tiers, credit mechanics, and what you actually pay

All three platforms offer free entry points, but the credit structures and upgrade paths differ.

Kaspr has a permanent free plan (no credit card required) with 15 B2B emails and 5 phone credits per month. Paid plans: Starter at $49/user/month (annual) with unlimited B2B emails and 1,200 phone credits per year; Business at $79/user/month (annual) with 2,400 phone credits per year. The "unlimited" B2B emails carry a fair-use cap of 10,000 per account per month.

Source: Kaspr

Phone and export credit caps are the real constraint: high-volume outbound teams on Starter will burn through their 100 monthly phone credits fast. Additional phone credits can be purchased (roughly $0.023–$0.036 each in annual bundles).RocketReach offers a free account with limited lookups (no credit card required). Paid plans are priced monthly: Essentials at $39/seat/month (email-only, 70 lookups and 70 exports per month, no phone numbers or advanced integrations), Pro at $79/seat/month (adds mobile and direct phone numbers, 200 lookups and exports per month, technographics, Autopilot, and CRM integrations), and Ultimate at $169/seat/month (adds 1,000 lookups and exports per month, higher limits, Salesforce custom mapping, Intent Data, and Healthcare Data). Plans enforce fixed monthly lookup and export limits per seat. Custom Team Plans are available with higher limits, team features, and support.

Source: RocketReach

ZoomInfo does not publish prices. All paid plans are custom-quoted based on seats, credits, features, and contract terms. Entry points exist: ZoomInfo Lite is a permanent free tier with access to the B2B database, 10 monthly export credits, and basic search features.

A 7-day free trial provides broader access. ZoomInfo's pricing reflects what it delivers: the data, the GTM Context Graph intelligence layer, conversation intelligence, orchestration, and AI agents.

Teams comparing Kaspr or RocketReach's annual cost to ZoomInfo's should also account for the separate tools they'd need to replicate what ZoomInfo includes (intent data provider, conversation intelligence, outreach platform, ABM tool, website visitor identification).

Integrations and technical access

Kaspr offers nine native integrations: HubSpot, Salesforce, Pipedrive, Zoho CRM, Lemlist, Brevo, Aircall, Ringover, and Zapier. All except Zapier are available on the Free plan.

The Kaspr API accepts LinkedIn profile URLs and returns enriched data, but API access is available only upon request (not self-serve) on Starter and Business plans. Rate limits are modest: 20 requests/hour on Starter, 250/hour on Business. No webhook support, no Make/Integromat integration, and the API does not accept Sales Navigator URLs.

Source: Kaspr

RocketReach provides native integrations with Salesforce, HubSpot, Outreach, Salesloft, Bullhorn, and Zapier (CRM integrations require Pro plan).

The API is more mature: RESTful with webhooks, bulk enrichment up to 100 profiles per batch, and a Universal Credits system for flexible consumption. Custom API packages start at $6K annually. Documentation is hosted at docs.rocketreach.co with an embedded AI assistant.

Source: RocketReach

ZoomInfo operates at a different scale. The App Marketplace lists 120+ partner integrations across CRM, marketing automation, sales engagement, data warehouse, and ATS categories.

The Enterprise API covers Data (search, enrich, technologies, org charts), Copilot (AI-powered account summaries, lookalikes, recommendations), Marketing (audience management), and Platform (engagement data) endpoints. API access is included in all relevant plans.

The MCP server connects ZoomInfo to AI models like Claude and ChatGPT, letting AI agents query ZoomInfo data through natural language.

Cloud Partners enables direct data ingestion into AWS, Snowflake, Google Cloud, and Databricks.

Security and compliance

For teams in regulated industries, the compliance posture of your data provider matters.

Kaspr processes data under legitimate interest (GDPR Article 6.1(f)) and is CCPA aligned. Infrastructure is hosted on OVH (France) with AWS backup in France.

Source: Kaspr

Kaspr notifies 50,000+ contacts daily as part of its opt-out process. However, no third-party security certifications (SOC 2, ISO 27001) appear on any Kaspr page. Enterprise compliance features like SSO and the ability to hide direct emails are restricted to the Enterprise plan.

RocketReach holds SOC 2 Type II and ISO 27001 certifications, both independently audited. A Trust Center (powered by Drata) provides transparency into security practices. Data is encrypted in transit (TLS 1.2+) and at rest (AES-256-GCM) on AWS infrastructure.

Source: RocketReach

GDPR compliance includes EU Standard Contractual Clauses, and RocketReach is registered as a data broker under Texas law. SSO via SAML 2.0 is available on Ultimate and Custom plans.

ZoomInfo maintains the broadest certification stack: ISO 27001, ISO 27701, SOC 2 Type II, TRUSTe GDPR, and TRUSTe CCPA, all renewed annually. ZoomInfo is a registered data broker in California and Vermont, with a dedicated Trust Center.

For enterprise procurement teams with strict vendor security requirements, ZoomInfo's certifications and privacy infrastructure (including ISO 27701, the privacy-specific extension) address compliance needs that the other two platforms may not satisfy.

Kaspr and RocketReach both solve the contact data problem well, with different strengths in geography, workflow, and pricing. For many teams, one of them is the right fit.

But for teams whose challenge extends beyond finding contacts to understanding accounts, timing outreach, and coordinating across sales and marketing, ZoomInfo provides the data, the intelligence layer, and the execution tools in one platform.

The question isn't which database is bigger. It's whether you need a database or a go-to-market engine.
