Check out the features, pros, & cons of the leading RB2B alternatives

13m 32s reading time

RB2B is a popular tool for tracking website visitors and generating leads, but is it the right solution for you? 

Maybe you’re looking for more features, better pricing, or something that integrates more easily with your workflow. Fortunately, there are plenty of other tools that could meet your needs.

Here’s a look at what the platform offers and the best alternatives to RB2B with their features, strengths, and pricing to help you choose your next sales investment.

What is RB2B?

RB2B (short for “Revenue B2B”) is a sales intelligence platform focused on website visitor tracking and identification. It tells you which companies are checking out your site even if they don’t submit their details, so you can focus on real interest in your product or services. 

RB2B’s main features are:

  • Lead enrichment: Get company details, industry insights, and contact data for website visitors to personalize your outreach. 
  • Salesforce and HubSpot integration: Keep everything organized and stay on top of leads. 
  • Real-time alerts and reporting: Get notified when high-intent visitors are actively engaging, so you can follow up while you’re still on their radar. 

In short, it’s a great tool for turning anonymous website visitors into potential leads. But if you’re looking for a platform that offers deeper contact insights, AI-powered outreach automation, or leads from outside the US, you might want to consider one of the leading alternatives to RB2B for sales.

AiSDR

AiSDR is among the top RB2B alternatives, combining real-time visitor intelligence with AI-powered outreach to help you identify and engage high-intent leads automatically. 

The AI goes beyond company-level tracking and identification by pinpointing actual decision-makers who visit high-intent webpages like your demo or pricing page, and crafts emails using over 323 buyer-specific insights.

In addition to sending emails and follow-ups, AiSDR can also independently reply to inbound lead requests, questions, and objections within 10 minutes. AiSDR’s GTM engineering team will even help you set up your GTM playbook and run sales plays like retargeting website visitors, reaching out to product champions, and messaging customer lookalikes.

AiSDR features the market’s deepest HubSpot integration, allowing you to automatically sync your active and static lists, pull custom properties for personalization, and create records for all net-new leads in HubSpot.

G2 score: 4.7/5 (44 reviews)

Key features

  • Intent-based visitor identification: De-anonymize website visitors and see which pages they view and how many times
  • AI-powered engagement: Send personalized messages based on visitor behavior and smart, timely replies to leads on autopilot
  • Easy campaign setup: Create microcampaigns that trigger outreach when a visitor matches your ICP and engages with key pages
  • Email framework library: Use AiSDR’s specialized sales persona for website visitors or train AI to speak like you, your top salespeople, or top sales leaders
  • Key integrations: Pull data from HubSpot, LinkedIn Sales Navigator, and ZoomInfo for enrichment and message personalization
  • Multi-channel outreach: Send messages via email, text, and LinkedIn, and generate personalized scripts for cold calls
  • Automatic lead enrichment: Enrich your website visitors with their contact details and additional intent signals, such as hiring intent, technology stack, and people new in their role

Pros

  • 24/7 GTM engineering support that will automate your GTM playbook
  • Access to ZoomInfo and Sales Navigator lead data
  • Multiple intent signals for richer messages (e.g. product champions, mentions in the news, etc)
  • Done-for-you email infrastructure and website visitor tracking setup

Cons

  • No Salesforce integration
  • Fixed pricing may cover more than smaller teams with little website traffic need

Why it’s a great RB2B alternative

AiSDR packs powerful features to help you turn website traffic into qualified leads without lifting a finger. 

While RB2B stops at company-level insights, AiSDR uncovers decision-makers your team can engage faster and more effectively through real-time data enrichment and signal-based outreach that drive more conversions.

In head-to-head A/B tests over several months, AiSDR consistently outperformed RB2B in de-anonymizing a higher percentage of visitors. And unlike RB2B – which sometimes surfaces irrelevant contacts who never visited your site – AiSDR only delivers verified, intent-driven prospects.

Pricing: Plans start at $900 per month for 1,000 emails, with discounts available for larger email volumes

Why it’s a great RB2B alternative

Compared to RB2B, Warmly’s website visitor tracking has the edge with real-time insights and AI-powered lead scoring. While RB2B sticks to company-level data, Warmly enriches individual profiles for more personalized outreach. Instant CRM syncing and simple pricing make Warmly an easy-to-use, mid-price solution.

Pricing: Limited free version available. Paid plans start at $499 per month.

6sense

6sense is a powerful account-based marketing (ABM) platform that uses AI to predict customer behavior and identify high-value accounts. It analyzes buyer intent signals to help sales and marketing teams focus on prospects who are actually ready to engage.

6sense uses predictive analytics and CRM integrations to connect you with the right buyers at the right time, then gives AI-driven recommendations for follow-up.

Why it’s a great RB2B alternative

6sense doesn’t just tell you who’s on your site: it predicts who’s ready to buy. The tool uses AI to uncover deep intent signals, helping your sales team strike while the iron’s hot. It’s a bigger investment, but if you want advanced ABM and higher ROI, 6sense delivers.

Pricing: Custom pricing.

Breeze Intelligence

Breeze Intelligence, part of the HubSpot sales suite, gives you a smarter way to manage customer data with real-time enrichment. It automatically fills in key details about companies and contacts, helping your team personalize outreach and connect faster. 

Breeze works natively with HubSpot, allowing enriched data to fit directly into your existing workflow. It helps identify high-value leads, segment audiences, and automate outreach, delivering the insights needed to close more deals. 

With its powerful API and advanced data engine, Breeze is a great choice if you already use HubSpot and want to enhance prospecting and gain deeper customer intelligence.

G2 score: 4.4/5 (620+ reviews)

Key features

Pros

  • Native HubSpot integration
  • Keeps data fresh with real-time updates

Cons

  • Doesn’t work as well with consumer email domains

Why it’s a great RB2B alternative

Breeze Intelligence goes beyond visitor tracking by enriching data to give you everything you need for targeted outreach. RB2B does a great job of providing basic company insights, but Breeze goes further by building detailed customer profiles and supporting segmentation. It’s a good, affordable solution for founders and small teams who are already using HubSpot.

Pricing: Pricing is included in the HubSpot package.

Leadfeeder

Like RB2B, Leadfeeder tracks which companies are checking out your site, giving you a behind-the-scenes look at potential leads you might otherwise miss.

If you want to turn website traffic into meaningful conversations, Leadfeeder makes it easy.

G2 score: 4.3/5 (710+ reviews)

Key features

  • Visitor identification: See which companies are browsing your website.

  • CRM integration: Syncs with Pipedrive, Salesforce, HubSpot, and more.

Pros

  • Easy CRM syncing for better follow-ups
  • Customizable filters to segment leads

Cons

  • Can’t track individual visitors, only companies
  • Some inaccuracies in niche industries
  • Support quality can be inconsistent

Why it’s a great RB2B alternative

Similar to RB2B, Leadfeeder tracks your website visitors, but it goes further by scoring leads and adding them directly to your CRM. Instead of just listing who stopped by, it prioritizes your top prospects and sends real-time notifications by email or Slack to keep your outreach activity efficient.

Pricing: Limited free version available. Paid plans start at $107 per month.
