RB2B vs. Apollo.io: Which should you choose?

About RB2B

RB2B reveals the exact visitors hitting your website — in real time. Get their names, emails, and LinkedIn profiles instantly, plus see which pages they viewed. We focus on US traffic only to keep things GDPR-clean. Your anonymous website ghosts become actionable leads delivered straight to Slack or your CRM — no dashboard hunting required.

About Apollo.io

Apollo.io packs 200+ million contacts into an all-in-one prospecting machine. Find email addresses, phone numbers, and LinkedIn profiles, then fire off email sequences and track engagement. It's your complete sales toolkit — prospecting, outreach, and basic CRM functions — starting at $49 per user monthly.

What do users say?

RB2B users aren't leaving detailed reviews in our source material — the content focuses on general B2B software review strategies rather than specific product feedback. We're seeing articles about review collection and business growth, but nothing diving into actual RB2B user experiences.

Apollo.io users praise the massive contact database and competitive pricing compared to expensive alternatives like ZoomInfo. They love the data quality, ease of use, and solid ROI. But here's the catch — users consistently report email deliverability nightmares. Emails bounce or land in spam folders, and billing practices are problematic with ignored cancellation requests and surprise charges. While Apollo delivers on lead generation and integrations, LinkedIn outreach limitations and data accuracy issues make some users question its reliability for comprehensive sales campaigns.

Comparison

RB2B

RB2B specializes in real-time website visitor identification — turning anonymous US traffic into instant, actionable leads delivered to Slack. Lightning-fast integration with laser-focused capabilities, but limited to US-only data coverage.

Apollo.io

Apollo.io delivers comprehensive all-in-one prospecting with 200+ million contacts plus sales engagement tools at competitive pricing. Feature-rich and cost-effective, but suffers from data accuracy gaps and email deliverability headaches.

Choose RB2B if you're targeting US B2B buyers and want to capitalize on warm website traffic immediately. Your strength lies in converting high-intent visitors the moment they engage — perfect for sales teams prioritizing speed over broad prospecting.

Choose Apollo.io if you're a startup or SMB needing comprehensive prospecting capabilities with extensive contact data at reasonable pricing. Apollo handles email sequences and offers a larger database, making it better for contact-based marketing — though neither platform delivers the sophisticated segmentation and automation that dedicated marketing platforms provide.

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

Here's what's revolutionizing ABM: your funnel isn't about anonymous accounts. It's about the decision-makers and influencers within those accounts.

Contact-based marketing (CBM) changes everything. Instead of chasing broad account intent signals, CBM pinpoints the exact people engaging with your content in real-time — even when they don't convert.

This solves traditional intent-based marketing's biggest problem — the ambiguity.

With contact-level data, you reveal high-priority leads by identifying individuals behind key touchpoints. Deliver hyper-targeted ads based on specific contact behaviors. Bridge the gap between marketing and sales with actionable, lead-level insights that actually move the needle.
