7 Best RB2B Alternatives for Website Visitor Identification in 2026

RB2B identifies the people visiting your website and pushes their LinkedIn profiles to you in real time. It's a clever concept. But visitor identification is only one piece of the lead generation puzzle. You still need to qualify those visitors, write outreach, and actually start conversations.

If RB2B isn't checking every box for you, here are seven alternatives worth evaluating.

1. Flocurve

Flocurve takes a different approach to finding and engaging leads. Rather than waiting for prospects to visit your website, it proactively monitors LinkedIn for buying signals and uses AI to start personalized conversations with the right people at the right time.

This matters because website visitor identification has an inherent limitation: you can only work with people who already found you. Flocurve flips that model. It scans LinkedIn for over 30 buying signals, things like recent funding rounds, executive job changes, competitor engagement, and hiring surges. Then its AI writes personalized outreach messages that reference those real signals, so your first touch feels relevant instead of random.

Key Features

• 30+ buying signal detection: Monitors funding, hiring, job changes, competitor activity, and more across LinkedIn
• AI-powered personalized messaging: Generates outreach that sounds human and references actual prospect activity
• Multi-channel campaigns: LinkedIn outreach and cold email from one platform
• Verified email discovery: Built-in email finding and validation
• CRM sync: HubSpot and Pipedrive integrations on the Scale plan

Pricing

• Growth: $149/mo (2 LinkedIn accounts, 200 verified emails, unlimited leads)
• Scale: $299/mo (5 LinkedIn accounts, 1,000 verified emails, CRM integrations)
• 7-day free trial, no credit card required

Pros

• Proactive lead generation vs. passive visitor identification
• AI outreach is genuinely personalized based on real buying signals
• Combines discovery, qualification, and outreach in one tool
• Predictable pricing that doesn't scale per user
• Quick setup with no technical integration required

Cons

• Not a website visitor identification tool, so it solves a different (arguably bigger) problem
• LinkedIn-focused, which may not cover all your channels
• CRM integrations currently limited to HubSpot and Pipedrive

2. Clearbit (Breeze Intelligence by HubSpot)

After being acquired by HubSpot, Clearbit became Breeze Intelligence. It identifies companies visiting your website and enriches leads with firmographic and technographic data. For HubSpot users, it's one of the most seamless visitor identification options available.

Key Features

• Company-level website visitor identification
• Real-time lead and account enrichment
• Form shortening to increase conversions
• Buyer intent scoring based on page visits and engagement
• Native HubSpot integration

Pricing

• Starts around $150/mo for basic credits
• Scales with enrichment volume
• Enterprise pricing for high-volume needs

Pros

• Excellent company-level identification accuracy
• Enrichment data is clean and well-structured
• Form shortening genuinely improves conversion rates
• If you use HubSpot, the integration is flawless

Cons

• Identifies companies, not individual visitors (unlike RB2B's person-level identification)
• Locked into the HubSpot ecosystem for full value
• Credit-based pricing can spike with traffic volume
• No outreach capabilities built in

3. Leadfeeder (now Dealfront)

Leadfeeder, now part of the Dealfront platform, has been in the website visitor identification space for years. It identifies companies visiting your site using reverse IP lookup and matches them against a business database. It's a mature product with solid integrations.

Key Features

• Lead scoring based on engagement patterns
• CRM integrations (Salesforce, HubSpot, Pipedrive, and more)
• Custom feed filters to segment and prioritize visitors

Pricing

Pros

• Established product with years of refinement
• Visitor behavior data adds useful context beyond just identification

• Free tier lets you test the concept before paying

Cons

• Company-level only, no individual person identification

4. 6sense

6sense is an enterprise account-based marketing (ABM) platform that goes far beyond simple visitor identification. It uses AI and intent data to predict which accounts are in-market and where they sit in their buying journey. It's built for large B2B organizations with complex, multi-touch sales processes.

Key Features

• The advertising component is only valuable if you're running paid campaigns
• Overlapping features with tools you may already have

6. Warmly

Warmly occupies an interesting middle ground. It identifies website visitors (both at the company and, in some cases, individual level), then helps you engage them in real time through chat, video, and automated outreach. It's the closest to what RB2B does, but with built-in engagement tools.

How to Choose the Right RB2B Alternative

Choosing the right tool comes down to answering a few honest questions about your sales process.

Do you actually have enough website traffic? Visitor identification tools are only as good as the volume of visitors hitting your site. If you get fewer than 1,000 monthly visits, a proactive outreach tool like Flocurve will generate more pipeline than any identification tool because it doesn't wait for people to come to you.

What level of identification do you need? Company-level identification (Clearbit, Leadfeeder, Albacross) tells you which businesses are visiting. Person-level identification (RB2B, Warmly) tells you which specific people are visiting. Proactive tools (Flocurve) skip identification entirely and go find the right people based on buying signals.

What's your budget reality? Enterprise ABM platforms like 6sense and Demandbase deliver serious value for large organizations, but they cost $25,000 to $50,000+ per year. If you're a startup or SMB sales team, tools in the $79 to $299/mo range will give you better ROI per dollar spent.

How important is the outreach component? Most visitor identification tools stop at telling you who visited. You still need a separate tool to actually reach them. Flocurve and Warmly both include engagement capabilities, which means fewer tools to manage and a shorter path from insight to conversation.

Where does your team sell? If you're focused on European markets, Albacross and Leadfeeder (Dealfront) have stronger data coverage there. For LinkedIn-heavy B2B sales in any region, Flocurve's signal detection works globally.

Frequently Asked Questions

What does RB2B actually do?

RB2B identifies individual people who visit your website and delivers their LinkedIn profile information to you, typically via Slack notifications. It uses a pixel installed on your site to match visitors against its database. The core value proposition is turning anonymous website traffic into named leads you can follow up with directly.

Is person-level visitor identification accurate?

Accuracy varies significantly between providers and depends on factors like visitor location, browser settings, ad blockers, and the size of the matching database. RB2B and Warmly both offer person-level identification, but match rates typically range from 15% to 40% of total visitors. A meaningful portion of your traffic will remain unidentified regardless of which tool you use.

Can I use visitor identification and outreach tools together?

Absolutely. Many teams combine a visitor identification tool with a proactive outreach platform. For example, you could use Leadfeeder to track which companies visit your pricing page, then use Flocurve to find the right contacts at those companies and send personalized LinkedIn messages based on buying signals. The identification tells you who's interested. The outreach tool starts the conversation.

Are there free alternatives to RB2B?

Several tools offer free tiers. Leadfeeder's free plan identifies up to 100 companies with 7 days of historical data. Warmly has a basic free plan for identification. Apollo.io offers free contact data (though it's not a visitor identification tool). Flocurve offers a 7-day free trial with full access to test its signal-based outreach approach.

How is signal-based outreach different from visitor identification?

Visitor identification is reactive. It waits for someone to visit your website, then tells you who they are. Signal-based outreach (what Flocurve does) is proactive. It monitors LinkedIn for buying signals like funding announcements, leadership changes, and hiring activity, then helps you reach out to those prospects before they ever visit your site. The advantage is volume and timing: you're not limited to your website traffic, and you can reach prospects at the moment a buying signal appears.

Conclusion

RB2B introduced a compelling idea: know exactly who's visiting your website and follow up personally. But visitor identification alone doesn't build pipeline. You still need to qualify those visitors, craft outreach, and manage follow-up.

If you want a tool that goes beyond identification and proactively finds the right prospects based on real buying signals, try Flocurve free for 7 days. If visitor identification is specifically what you need and you want real-time engagement, Warmly is strong. For budget-friendly company-level identification, Leadfeeder gives you a good starting point.

The best approach for most teams is to stop relying solely on who finds you and start proactively finding the people most likely to buy.
