Top 10 RB2B Alternatives & Competitors [2026]

In this article, I’ll explore the top 10 RB2B alternatives to help you find the perfect solution for your specific use case.

TL;DR

Warmly offers the best alternative to RB2B with its AI-powered lead identification, sales automation, and real-time engagement capabilities.
Sales intelligence tools like Factors.ai and ZoomInfo are ideal for companies looking to unify cross-channel intent signals and run predictive prospecting campaigns.
On the other hand, platforms like Lusha and Dealfront can help you drill down into highly targeted segments or expand into GDPR-compliant European markets.

But before I get to these alternatives, let’s look at some potential reasons you might be looking for an alternative to RB2B in the first place.

Why Do You Need an RB2B Alternative?

There are three main reasons why users look for alternatives to RB2B. 👇

Reason 1: Limited Visitor Tracking (US only)

RB2B only tracks website visitors from the US. Its pixel only fires for US IP addresses and identifies traffic from profiles of US geolocations.

Although this frees the platform data of any GDPR regulations, websites with traffic coming in primarily from locations outside the US won’t be able to use the tool effectively.

Reason 2: Credit-Based Pricing

RB2B offers two core plans: Free and Pro. Both work on credit-based usage. The free plan limits you to 200 credits per month, while the paid plan offers the same credits but allows you to purchase additional ones.

Here’s the catch: each lead discovery costs 1 credit, so 200 credits will fall short.

Another issue with this system is that RB2B users have observed a rare ‘false positive’ instance where the credit is being used up, but the data the software gives isn’t accurate. This can lead to quick exhaustion of your credits.

Reason 3: Expensive

Of course, RB2B comes with a free forever plan. But, the jump from free to paid tier is significant for many users.

Also, when you opt for the Pro plan, the amount of credits will remain the same (200 credits). Purchasing additional credits starts at $119 per 200 credits and can significantly go up as usage increases.

1. Warmly

Warmly offers the best alternative to RB2B it helps you identify your warmest leads and reach out to them immediately with our engagement features.

Heads up: Warmly is our platform. I'll keep the comparison honest and I'll explain how our solution is the best alternative to RB2B.

Warmly isn't only a website visitor identification tool. The platform combines visitor de-anonymization with AI chat, AI SDR outbound, buying committee identification, and a learning intelligence layer.

That's what makes Warmly a credible alternative to running a separate chatbot, dialer, visitor ID, and data stack - it's a single system with one shared brain.

Let’s go over the features and capabilities that I think make our platform a reasonable alternative to RB2B:

Person and company-level visitor identification

Warmly identifies visitors at the individual level, similar to RB2B.

Across typical B2B traffic, that's around 65% of companies and roughly 15% of individuals identified, with the full identification, enrichment, and scoring pipeline running in under three seconds.

Our platform goes beyond IP-to-company matching and resolves individuals with name, work email, job title, and LinkedIn profile.

AI Chat and Live Human Chat

You’ll get access to Warmly’s AI chatbot that you can train on your messaging and objection-handling techniques that you’ve perfected over the years.

The chatbot can pull CRM history and intent signals before the first message, and opens with something the visitor actually cares about rather than "How can I help?"

When a conversation needs a human, the handoff comes with the full transcript and context intact, so reps don't start cold.

Qualified visitors can book straight into rep calendars from inside the chat. No form, no SDR triage step, and no "someone will be in touch."

The Context Graph

The Context Graph is our platform’s unified data layer that connects 4 types of information for every account:

What happened to them (signals)? This includes Website visits, intent signals, funding news, job changes, and competitive research.
What did you do (actions)? That’d be your emails sent, ads served, calls made, and sequences triggered.
What are the notes around it (context)? Your rep observations, meeting summaries, deal context, and why decisions were made.
What was the result (outcomes)? This includes meetings booked, deals won, conversations had, and outcomes tracked.

What that means is that your inbound and outbound work can work from the same scoring model instead of passing data between three vendors.

Every prospect touchpoint is logged in an activity ledger, which you’ll find is quite useful when a prospect is back in market after a few months of persuading stakeholders to give them budget.

You’d also be right to assume this massive context goes to the AI chatbot.

The AI chatbot would be aware if a visitor visited your pricing page last week and a case study 2 months ago.

TAM Agent (AI SDR + Outbound Orchestration)

The TAM Agent handles everything that happens off-site.

That includes building dynamic audiences, scoring accounts, finding the buying committee, enriching contacts, and orchestrating outbound across email, LinkedIn ads, and rep sequences.

Here’s what’s included:

AI ICP Tiering: ML model trained on your closed-won deals that scores every account as Tier 1, 2, 3, or Not ICP, with a transparent reason for each score.
Buying Committee Identification: Goes beyond title matching to find Champions, Decision-makers, Influencers, and Approvers using LinkedIn data, org charts, and job descriptions.
Outbound Orchestration: Three modes (route to reps, AI SDR autonomous, or hybrid), with guardrails that won't sequence open opportunities or double-touch visitors already in chat.
LinkedIn Ad Targeting: Auto-syncs buying committee members from high-intent accounts to LinkedIn Matched Audiences in real-time.

Warmly's Integrations

Warmly integrates natively with HubSpot and Salesforce, with full bidirectional sync, custom properties, workflow triggers, and Change Data Capture on the Salesforce side.

For sales and engagement, our platform connects to Slack, Microsoft Teams, Outreach, Salesloft, Apollo, and Instantly.

On the marketing side, native integrations cover LinkedIn Ads, Google Ads, Meta Ads, and Marketo.

Pricing

Warmly's current pricing plans are structured into three tiers plus a free entry point:

Free: 500 de-anonymized visitors per month at the company and contact level, limited Bombora intent signals, no automation.
TAM: Starts at $15,000/year. Covers off-site orchestration, ICP tiering, buying committee ID, full enrichment, and LinkedIn ad sync.
Inbound: Starts at $30,000/year. Covers on-site person-level identification, AI chat, meeting booking, Warm Offers (pop-ups), personalized microsites, and retargeting.
Full GTM: Custom pricing. Unifies both agents with the Context Graph, SSO, SAML, and API, plus MCP access.
