ZoomInfo vs. RB2B: Which should you choose?

About ZoomInfo

ZoomInfo is a B2B data platform with an extensive contact database containing hundreds of millions of contacts with emails, direct dials, and org charts. It delivers firmographic and technographic data, intent signals, and website visitor tracking. The platform connects with major CRMs, marketing automation tools, and sales engagement platforms through native integrations, APIs, and a Chrome extension. It's structured as multiple modules (SalesOS, MarketingOS, etc.) serving different GTM functions.

The service runs on enterprise-oriented custom pricing, typically starting around $15k/year, scaling based on users and data consumption. It's built for mid-to-large B2B sales and marketing teams needing comprehensive contact data for outbound prospecting and targeted lead generation. While offering strong data accuracy for established companies and broad coverage (especially in North America), users often hit data gaps in niche markets. ZoomInfo gathers data through web scanning, while maintaining compliance mechanisms for privacy regulations.

About RB2B

RB2B delivers website visitor intelligence for U.S. traffic, transforming anonymous visitors into actionable leads. It identifies visiting companies in real-time and reveals person-level details including names, titles, LinkedIn profiles, and emails of visitors. The platform tracks which pages were visited for intent context and instantly pushes this data through integrations with HubSpot, Salesforce, Slack, and dozens of other tools via Zapier/Webhooks.

The service runs on a freemium model with a limited free tier (150 credits/month) and paid plans starting at $149/month for 300 credits. It's built specifically for B2B companies targeting the U.S. market, intentionally excluding non-U.S. traffic to avoid GDPR compliance issues. This U.S.-only focus creates high accuracy in company identification but limits its usefulness for businesses with significant international traffic.

Comparison

ZoomInfo

• ZoomInfo offers a vast B2B contact database with hundreds of millions of records including emails, phone numbers, and company information. Pricing is enterprise-oriented with entry-level contracts starting around $15k annually, making it expensive for smaller businesses.

• The platform integrates with major CRMs and marketing tools but locks you into annual contracts that are difficult to escape. While data quality is generally high for established companies, coverage can be spotty for niche markets, and many users have privacy concerns about ZoomInfo's data collection methods.

RB2B

• RB2B delivers real-time website visitor intelligence exclusively for U.S. traffic, identifying companies and revealing person-level contact details when prospects visit your site. The platform runs on a freemium model with paid plans starting at $149/month, requiring no long-term contracts.

• While offering strong integration capabilities with Slack, CRMs and other tools, RB2B is limited to U.S. data only and lacks the extensive database of ZoomInfo. The real-time nature of the data and immediate actionability are core strengths, but global businesses will find the regional limitations restrictive.

ZoomInfo fits large enterprises needing extensive contact data for outbound campaigns across global markets. The comprehensive database enables traditional contact-based marketing at scale, though at significant cost and with annual commitments. Mid-sized companies targeting the U.S. market will find RB2B's approach more nimble and cost-effective.

RB2B cannot support broad contact-based marketing campaigns since it only provides data on companies that have already visited your website. Contact-based marketing remains essential for businesses needing to reach cold prospects who haven't discovered them yet. Companies serious about comprehensive outbound efforts may need both tools—ZoomInfo for broad market coverage and RB2B for immediate engagement with active prospects.

Do you need account-based marketing, or something else?

Here's the revelation that's flipping ABM on its head: your funnel isn't about anonymous accounts. It's about the decision-makers and influencers within those accounts.

That's what makes contact-based marketing (CBM) a breakthrough. Instead of focusing on broad account intent signals, contact-based marketing pinpoints the EXACT people engaging with your content in real-time, even when they don't convert.

How does this solve the traditional tension of intent-based marketing? It clears up the ambiguity.

With contact-level data, you can reveal high-priority leads by identifying the individuals behind key touch points. Deliver hyper-targeted ads based on specific contact behaviors. And bridge the gap between marketing and sales alignment with actionable, lead-level insights.
