RB2B vs. Apollo.io – which should you choose?

About RB2B

RB2B is a web visitor intelligence platform that identifies companies visiting U.S.-based websites in real-time, delivering person-level contact details including names, titles, LinkedIn profiles, and emails. It tracks which pages were visited to provide intent context, and integrates seamlessly with HubSpot, Salesforce, Slack, Clay, and other tools via Zapier/Webhooks. The platform runs on a freemium model with credit packs — offering a limited free tier (150 credits/month) and paid Pro plans at $149/month (300 credits) or $249/month (600 credits).

The service processes U.S. traffic data only, intentionally avoiding GDPR headaches by not tracking European visitors. This U.S.-only focus creates limitations for global businesses but simplifies compliance. RB2B delivers data instantaneously when prospects visit your site, but its dataset relies on integrations for enrichment rather than a proprietary database — meaning some visiting companies might not have readily available contacts if enrichment fails. The platform prioritizes speed and actionability, turning anonymous website traffic into immediate sales opportunities.

About Apollo.io

Apollo.io is a contact database platform with sales engagement features built in. It provides access to over 200 million contacts with emails, phone numbers, and LinkedIn profiles, along with basic intent signals for higher-tier plans. The platform combines prospecting capability with email sequencing and basic CRM functions, integrating with Salesforce, HubSpot, Gmail, and Outlook through its Chrome extension.

The service runs on a freemium model with paid tiers ranging from $49 to $119 per user per month when billed monthly. While offering global data coverage, Apollo's information is strongest for North America and Europe. The platform fits startups, SMBs, and cost-conscious mid-market teams who need both prospecting tools and outreach capabilities in one system — though its data accuracy varies and some contacts may be outdated.

Comparison

RB2B

• RB2B provides website visitor intelligence focused on U.S. traffic, converting anonymous visitors into actionable leads. It delivers real-time data with person-level identification and integrates with various tools through native connectors and Zapier.

• The platform offers limited functionality in its free tier but unlocks more comprehensive features in paid plans starting at $149/month. Its U.S.-only approach limits global reach but simplifies compliance issues for companies primarily targeting American businesses.

Apollo.io

• Apollo.io offers a massive contact database of over 200 million profiles with email sequences and basic CRM functionality in one platform. Its Chrome extension enables data access while browsing LinkedIn or Gmail, with integrations for major CRMs but limitations with some platforms.

• The tool uses a freemium model with affordable paid tiers starting at $49/user/month, offering broad global data coverage but with some accuracy challenges. Apollo attempts GDPR compliance but operates in somewhat gray areas regarding data collection methods.

RB2B makes most sense for US-focused B2B companies wanting to capitalize immediately on website visitors with high-intent. The real-time nature of its data makes it valuable for teams who prioritize speed and want to strike while interest is hot — especially those already using Slack for team communication. It's not suitable for global prospecting but works well as a complement to other marketing tools.

Apollo.io better serves teams needing broad prospecting capabilities across multiple regions, especially startups or SMBs with limited budgets. It enables contact-based marketing (directly reaching out to potential customers regardless of their previous interaction with your company), which RB2B doesn't support since it only identifies visitors to your own properties. Contact-based marketing is essential for many B2B strategies as it allows proactive outreach to potential customers who haven't discovered your company yet, significantly expanding your addressable audience beyond just inbound interest.

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. Bridge the gap between marketing and sales alignment with actionable, lead-level insights.
