RB2B vs. 6sense: Which should you choose?

About RB2B

RB2B reveals the exact companies visiting your website—in real time. You get contact details like names, emails, and LinkedIn profiles for those visitors, but there's a catch: US traffic only. It pushes this intel instantly to Slack or your CRM through seamless integrations, transforming anonymous website ghosts into actionable leads without forcing you to babysit another dashboard.

About 6sense

6sense is an enterprise ABM powerhouse that tracks anonymous buying signals and third-party intent data—using AI to predict where accounts sit in their buying journey. It connects with CRMs and marketing platforms to orchestrate multi-channel outreach based on predictive account scoring, though it demands custom enterprise pricing and complex implementation that'll make your head spin.

What do users say?

The user reviews for RB2B remain elusive—no specific feedback surfaced in our research. The available content focuses on B2B software review methodologies and general guidance rather than actual user experiences with RB2B itself.

6sense gets mixed reviews with some serious concerns about data reliability. Users frequently discover that intent data doesn't translate into actual buying activity—prospects often deny knowledge of the supposed research activity when contacted directly. While some appreciate 6sense for account prioritization and general prospecting insights, many describe the intent signals as "flimsy" or downright inaccurate. Several companies have ditched the service entirely due to unreliable data. The consensus? 6sense might help with internal prioritization, but its core promise of identifying genuine buying intent is questionable at best.

Comparison

RB2B

RB2B excels at real-time website visitor identification with instant contact enrichment—delivering actionable lead data straight to Slack and CRM systems. The downside? Its US-only focus severely limits global businesses, and the free tier delivers minimal functionality without email contacts.

6sense

6sense offers comprehensive ABM capabilities with advanced predictive analytics to identify account buying stages and orchestrate multi-channel campaigns. The platform's complexity and sky-high costs challenge smaller teams, while contact data coverage remains limited compared to dedicated databases.

RB2B suits smaller to mid-market US-focused companies that prioritize speed and simplicity in converting website visitors to leads. Its real-time Slack integration and straightforward pricing make it perfect for teams wanting immediate action on inbound interest—no complex setup headaches required.

6sense serves enterprise organizations with sophisticated ABM strategies, long sales cycles, and dedicated resources for platform management. Here's the reality check: while both tools provide some contact data, neither replaces dedicated contact databases like ZoomInfo. That's a critical limitation since effective B2B marketing requires comprehensive contact information for multi-touch campaigns, personalized outreach, and account penetration strategies that these intent-focused platforms simply can't support.

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

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

Enter contact-based marketing (CBM)—a complete breakthrough. 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.

How does this solve the traditional tension of intent-based marketing? It eliminates the guesswork.

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