RB2B vs. Clearbit: Which should you choose?

About RB2B

RB2B reveals the EXACT people visiting your U.S. website in real-time. It doesn't just show company names—it delivers person-level details (names, titles, LinkedIn profiles, emails) while tracking which pages they viewed. The system plugs directly into your existing sales tools—HubSpot, Salesforce, Slack, Clay—and connects to 50+ other apps via Zapier/Webhooks, functioning as your instant data pipeline for visitor intelligence.

Start free with 150 credits monthly, or upgrade to Pro starting at $149/month for 300 credits. RB2B deliberately avoids GDPR headaches by focusing exclusively on U.S. traffic, delivering contact data instantly when prospects hit your site. While it offers powerful real-time identification and seamless integrations, be aware of its U.S.-only coverage, limited free tier, and newer market position compared to legacy platforms.

About clearbit

Clearbit transforms minimal inputs—like a single email or domain—into detailed company and contact intelligence. It harvests data from public web sources and proprietary databases, delivering firmographic details, contact information, technographic insights, and IP intelligence to de-anonymize website visitors. The platform integrates through developer-friendly APIs and native connections with HubSpot (now as "Breeze Intelligence"), Salesforce, Marketo, and web forms.

Growth teams and marketers love Clearbit for shortening forms, boosting conversion rates, and personalizing outreach with richer data. It offers global coverage across all countries—though data depth varies based on a company's digital footprint. Each enriched record consumes credits on a volume-based pricing model. Following HubSpot's acquisition, Clearbit maintains its developer-friendly approach while embedding deeply into the HubSpot ecosystem.

Comparison

RB2B

• RB2B specializes in real-time U.S. website visitor identification with person-level contact details. Data springs from your actual site traffic and gets enriched instantly—focusing solely on U.S. visitors to sidestep GDPR complexities.
• Plugs right into HubSpot, Salesforce, Slack, Clay, and connects to 50+ apps via Zapier/Webhooks. Pricing follows a freemium credit model starting at $149/month for Pro features, with limited functionality in the free tier.

Clearbit

• Clearbit delivers enrichment data for leads and accounts, gathering firmographic details, contact information, and technographic data globally. It transforms minimal inputs into comprehensive intelligence while maintaining data freshness.
• Integrates with HubSpot (now as Breeze), Salesforce, Marketo, and offers robust API capabilities for developers. Pricing remains opaque and volume-based since joining HubSpot, with costs potentially climbing for high-volume enrichment needs.

RB2B fits U.S.-focused B2B companies wanting immediate action on website visitors. It transforms anonymous traffic into actionable leads instantly—perfect for teams prioritizing speed from site visit to outreach and leveraging Slack for real-time alerts.

Clearbit serves global businesses needing comprehensive data enrichment across their marketing stack. Both tools enable contact-based marketing, but differently—RB2B through real-time visitor identification and Clearbit through enriching existing leads—making them complementary rather than competitive for marketers needing both immediate engagement and thorough data enhancement.

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.
