Top 10 RB2B Alternatives for Marketers In 2025

The software helps marketing teams identify the companies and contacts visiting your website with filters to help you drill down on high-value prospects.

However, some users of the platform are not satisfied with its expensive pricing structure that quickly scales with credit usage, contact data that is not always accurate, and a limited range of integrations.

In this buyer guide, I’ll cover the 10 best RB2B alternatives in 2025 for marketers that will help you identify accounts and then reach out to them.

TL;DR

Warmly offers the best alternative to RB2B for marketers with its real-time website deanonymization, multi-channel AI-driven outreach, and signal-based ad targeting capabilities.
ABM-focused tools like 6sense and ZoomInfo are ideal for enterprise-level teams that need large B2B databases, predictive intent, and advanced audience segmentation.
On the other hand, there are tools like Snitcher and Dealfront that can help you identify companies visiting your site at a lower cost, especially if you’re focused on IP-based tracking or GDPR-compliant European data.

Before we start, I want us to cover some of the main reasons why some marketing managers have been looking to switch from RB2B: ⤵️

Why have some marketing teams been looking to switch from RB2B?

The main reasons why some marketers have been looking to switch from RB2B include its expensive credit-based pricing system, often inaccurate contact data, and limited range and depth of integrations.

But don’t get us wrong here, we’re not saying that RB2B is a terrible product that needs to be switched from.

Hundreds of marketers are satisfied with how the platform pushes visitors’ LinkedIn profiles to their Slack as soon as it identifies them.

Despite this, some marketing teams have been dissatisfied with the visitor identification software for a few reasons:

#1: The credit-based pricing system stacks up costs quickly

The #1 complaint about RB2B has been about its credit-based pricing system, which starts at the seemingly affordable rate of $129/month, but then scales up as more visitors land on your website.

One verified user of the platform mentions that they’re currently paying about $400/month for the platform, and their credits are running out quickly depending on their level of traffic.

‘’The credit-based pricing model is a drawback. After the free trial of 700 credits, costs jump from about $100/month for 200 credits to nearly $400/month for 700 credits, which can run out quickly depending on traffic.’’ – G2 Review.

#2: The contact data is not always accurate

Next up, users of the platform are not happy with how inaccurate some of the contact data can be, meaning that it can be someone else from the company visiting your website.

➡️ This can result in not only wasting your sales team’s time but also losing a potential customer by not targeting the right person.

‘’The biggest downside is that not all contacts showing in the platform are accurate. We have run a few tests and done a few outreaches that indicate the people identified in the platform are not the actual people visiting the site, but there is someone from that company visiting the site.’’ – G2 Review.

#3: Limited range and depth of integrations

Last but not least, users of the platform mention that the solution is still short on integrations, as it is still relatively new.

➡️ Some verified reviews also mention they wish the integration with HubSpot were a little deeper.

‘’They are still short of integrations in general, but cool progress for a new solution.’’ – G2 Review.

#1: Warmly

Warmly (that’s us) offers the best RB2B alternative on the market for marketing teams with its signal-based revenue orchestration platform.

Behind this definition stands a simple yet powerful lead generation and conversion machine, as Warmly:

Picks up buyer intent signals prospects drop off on your channels and across the web.
Translates them into actionable insights to help you understand who your hottest leads are right now.
Leverages those signals and insights to orchestrate comprehensive outreach workflows.

Let’s get a closer look at some of the features that make Warmly an attractive solution for marketing teams:

Feature #1: Identifies your website visitors to the contact level

Warmly lets you maximize your website’s lead generation potential by identifying both the companies and individuals visiting it.

You can simply add a snippet of Warmly’s code to your website, and the tool will start revealing leads in minutes.

In addition to essential company and individual-level identification, Warmly will also enrich each visitor’s:

Contact data (email address, phone number, social media profiles, etc.).
Firmographics (company location, size, funding, etc.).
Demographics (individual names, job positions, etc.).
Technographics (tools and software a company utilizes).

This will give you a better idea of your leads, where they’re coming from, and how well they match your ICP.

➡️ Warmly’s code snippet can be added to event pages or email campaigns, allowing you to capture leads across your owned channels.

Feature #2: Reveals your warmest leads based on intent data

I understand that knowing who your prospects are is only one part of successful outreach and conversion.

This is why Warmly collects intent data for each lead, allowing you to understand who your hottest leads are right now.

The platform captures three types of intent signals:

First-party intent, which includes intent signals leads left in your channels (website, app etc.), such as website visits, the specific pages they visited, time spent on high-intent pages, recurring visits, etc.
Second-party signals, which come from monitoring LinkedIn for things like job change intent, new funding rounds, etc.
Third-party intent, including web searches that include keywords relevant to your product, visits to competitors’ websites or interactions with their ads, etc.

As a result, your team will get:

A complete overview of which of your leads are most likely to convert right now.
Critical insights into each lead, which they can leverage to tailor their outreach strategies accordingly.

Feature #3: Signal-based sales orchestration

Regardless of how good and alert your sales reps are, some warm leads always fall through the cracks.

Our software handles this by enabling you to automate essential outreach workflows, ensuring you’ll never miss a high-value opportunity again.

Firstly, there’s the Orchestrator, which lets you set up automated email and LinkedIn outreach sequences by:

Specifying the trigger that sets the sequence in motion (e.g., a visitor matching your ICP lands on your website).
Defining the criteria the visitor needs to meet to be targeted (company size, industry, individual’s job role, etc.).
Specifying the frequency at which you want the workflows to run and the maximum number of people targeted in a single account.
Deciding on the action you want the Orchestrator to take (send contextual email and/or personalized LinkedIn DM or connection request).

Next up, AI Chat, Warmly’s AI-powered sales chatbot, automatically engages and qualifies leads, offers collaterals, answers questions, and books meetings while ensuring that every interaction with every lead is contextual and personalized to their prior interactions.

Finally, our platform lets you automate lead routing, as your reps will be notified in Slack the second a high-intent lead or visitor matching your ICP lands on your website.

Feature #4: Signal-based ad targeting

Warmly also lets you leverage onsite and offsite signals (e.g., LinkedIn engagement) to create highly targeted custom ad audiences.

For example, using Bombora intent data and Warmly’s Orchestrator lets you detect when companies are researching your competitors, integration partners, or relevant keywords.

Warmly then syncs those companies to LinkedIn Ad audiences, triggering campaigns that speak directly to what those prospects are actively exploring.

Warmly’s DemandGen AI agent does the same, but at a higher level.

Our AI agent uses all three types of intent signals to detect high-value opportunities, including them instantly in paid social campaigns across LinkedIn, Google Ads, Facebook, etc.

The result is a constantly refreshed audience of in-market accounts that sees highly relevant ads on all the channels they live in, while your competitors are still guessing.

It’s a scalable, automated solution to increase awareness, warm up your ICP, and capture mindshare early in the buying journey.

Pricing

Warmly’s pricing is modular and component-based.

You can choose the components that best match the needs of your business, as components are priced by output and not just a monthly fee.

How does Warmly compare to RB2B for marketing teams?

Here are some of the key aspects to keep in mind when comparing Warmly to RB2B as a marketer:

#1 Intent Data Granularity

Warmly: Tracks 1st, 2nd, and 3rd-party intent (website visits, LinkedIn job changes, competitor research) to identify real-time buyer signals.
RB2B: Focuses on person-level, real-time website visitor identification (names, titles, LinkedIn profiles, pages viewed).

#2 Account Scoring & Prioritization

Warmly: Built-in AI scoring ingests top-customer data + signals to produce dynamic prioritization and real-time rankings of in-market prospects. Designed to guide “best next step” actions.
RB2B: Surfaces high-intent visitors and signals; primarily provides raw person/company intent and enrichment for use in external systems. Scoring and prioritization are typically handled in CRM or ABM platforms.

#3 Integrations

Warmly: Native connectors with HubSpot & Salesforce, Slack/Teams alerts, CSV/webhook exports, integrations with Salesloft/Outreach and 100+ sales/marketing tools. Also supports ad audience syncs.
RB2B: Native Slack pushes and direct CRM integrations (HubSpot, Salesforce), plus Zapier/webhooks. Positioned as a lightweight real-time data feed into Slack, CRM, or automation tools.

#4 Personalization & Outreach

Warmly: Provides native outbound orchestration, automated email + LinkedIn sequences (Orchestrator), AI Chat chatbot for engagement/qualification, contextual outreach, and automated lead routing.
RB2B: Does not offer deep native multi-channel orchestration. Primarily a data source for outreach tools rather than an execution platform.

#5 Audience Building & Segmentation

Warmly: Builds audiences from onsite + offsite signals (e.g., LinkedIn engagement, competitor research). DemandGen AI automatically refreshes and syncs audiences to ad platforms.
RB2B: Enables creation of lists/segments from person-level activity (page visits, behaviors) and export to marketing systems. Audience orchestration and ad platform sync are not core capabilities.

#6 Campaign Automation & Orchestration

Warmly: Orchestrates full-funnel workflows triggered by signals, including email, LinkedIn, Slack alerts, and ad audience syncs.
RB2B: Can trigger Slack/CRM alerts and exports via Zapier/webhooks for automation within your own stack. Does not offer the same level of native orchestration or AI agents.

#7 Pricing & Plans

Warmly: Starts at $10,000/year (AI Data Agent). Higher tiers: Outbound Agent $14,600/year; Inbound Agent $20,000/year. Modular add-ons available.
RB2B: Freemium model: free tier with Slack pushes (limited by credits). Paid plans scale with usage/credits, charging per identified visitor. Person-level features are included during trial.

➡️ Choose Warmly if you want a single platform that both collects person-level signals and runs AI-driven orchestration (scoring → automated multi-channel outreach → ad audience syncs).

➡️ Choose RB2B if you primarily need a fast, lightweight source of real-time person-level website IDs (especially for U.S. traffic), Slack/CRM alerts, and an inexpensive way to feed enrichment into your existing automation/ABM tools.

Pros & Cons

✅ Lets you identify both companies and individuals visiting your website.

✅ Enriches each identified lead with detailed B2B intelligence and reveals intent data.

#2: 6sense

Best for: Detecting hot prospects on your website and then putting personalized email creation on autopilot.

Similar to: Warmly.

6sense offers an intent-driven ABM platform that uses intent signals to help you identify and prioritize surging accounts from the get-go.

The tool’s website deanonymization solution is a good enough RB2B alternative as it identifies anonymous website visitors by matching their IP addresses and behavior data with its massive B2B intent database.
