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.
Disclosure: Even though Warmly is our tool, I’ll aim to provide an unbiased perspective on why Warmly offers the best RB2B alternative in 2025.
Warmly offers a signal-based revenue orchestration platform that lets you:
- Identify website visitors.
- Reveal which visitors are most likely to convert right now.
- Gain quality insights into prospective customers, allowing your sales reps to tailor their strategies accordingly.
- Automate essential sales processes on top of buying intent signals.
Let’s look at some features that make Warmly so popular among GTM teams worldwide looking to switch from RB2B:
Warmly's Outbound Sales Tools
Warmly has two types of tools for sales outbound - AI SDR and AI Copilots.
Our platform continuously monitors website traffic to identify visitors who show buying intent.
The way it works is that the AI agent detects intent by pulling and analyzing various data, such as firmographics, contact details, and behavioral insights like pages visited, time spent on-site, interactions with competitors’ content, etc.
Once a visitor on your website is identified as high-intent, Warmly's AI SDR initiates personalized outreach through email, LinkedIn, or chat, ensuring the messaging is perfectly tailored to the visitor's behavior and profile.
After this, the AI SDR takes care of follow-ups to further nurture the leads and guide them down your sales funnel.
At the same time, Warmly’s AI Copilots assist your sales reps by:
- Looping in your human reps when it comes to interactions with the warmest leads.
- Providing your team with real-time insights and recommendations so your reps reach out to the highest-value leads at the best time, and so they do the right thing to convert them.
Sales Automation To Put Your Sales Ops On Autopilot
Warmly has several automation features to help you put essential sales operations on autopilot and ensure that no quality lead slips through the cracks.
Firstly, the Orchestrator lets you streamline LinkedIn and email outreach by automatically adding high-intent leads to specific sequences.
Our tool lets you set up all the essential parameters so you can completely customize it to fit your needs, goals, and target market, including letting you:
- Specify the trigger that sets the sequence in motion (e.g., a visitor goes to a high-intent page, such as pricing).
- Define the criteria the visitor needs to meet to be targeted (e.g., company size, industry, job role).
- Set up the frequency at which you want the workflows to run and the maximum number of people targeted in a single account.
- Decide what action you want the Orchestrator to take (e.g., sending a contextual email, personalized LinkedIn DM, or connection request).
Try it yourself 👇or watch it in action.
AI Chat That Only Engages The Leads You Want To
Our AI Chat leverages the power of AI to engage high-intent leads on your website by:
- Asking them qualifying questions.
- Answering their queries.
- Booking meetings.
- Offering relevant collaterals, etc.
➡️ The AI Chat is fully customizable, meaning you can train it to your specific brand tone of voice and other requirements.
The tool actively monitors both on-site and off-site intent signals, such as:
- Which pages a visitor browses.
- How often do they return?
- Whether the leads have already engaged with outbound campaigns.
- If the leads are already in your CRM from a previous deal cycle.
- Whether the prospect has already researched your competitors, etc.
💡 The AI chat then uses these signals to qualify and score leads more accurately, which means that it scores them on the actions they take and not on what they say.
Note: On Warmly’s Business plan and above, you can also automate lead routing using the round-robin method or set up any other criteria by which you want leads to be distributed.
Live lead engagement with Warm Calls
Warmly has another trick up its sleeve against RB2B1 for users who want to make the most of the traction gained by the intent insights the platform uncovers.
Our platform lets you engage your leads in a live video call while they’re still on your website.
When you go to the “Warm Calls” section of Warmly’s dashboard, you can see who’s visiting your website and monitor their sessions in real-time.
Once your reps assess the time is right, they can hop on a video call straight from Warmly’s dashboard.
As any sales rep knows, nothing can help you close more deals than one-on-one meetings, so make sure to make the most of them.
Note: The Live Video Chat feature is available only on Warmly’s Enterprise plan.
