What are the best RB2B alternatives in 2025?

Quick Answer: RB2B removed its free plan in 2025, leaving budget-conscious teams without a zero-cost option for person-level website visitor identification. The best alternatives right now are Snitcher (best value for EU company-level data), Warmly (best for real-time sales triggers), Koala (best for product-led teams), Leadfeeder (best for CRM-connected pipelines), Factors.ai (best for multi-touch attribution), Clearbit/Breeze (best for HubSpot users), and 6sense (best for enterprise intent data).

RB2B built its early following on one thing: a free plan that pushed LinkedIn profiles of US website visitors directly into Slack. When that free tier disappeared, thousands of teams were left looking for a replacement overnight.

The problem is that no single tool does exactly what RB2B did. Some identify companies but not individuals. Some cover EU traffic but not US. Some require a six-figure contract before you see a single lead. This guide cuts through the noise and matches each alternative to the teams most likely to get real value from it, based on traffic geography, identification depth, and budget.

The 7 Best RB2B Alternatives in 2026

1. Snitcher: Best Value for EU and US Company-Level Identification

Why we picked it: Snitcher identifies the companies visiting your site and enriches each record with firmographic data, contact details, and intent signals. It covers both EU and US traffic, which RB2B never did reliably, and its pricing starts at a fraction of what enterprise tools charge.

Best for: Small to mid-size B2B teams that need company-level identification across geographies without paying enterprise rates.

Key feature: Real-time visitor alerts with CRM integrations for HubSpot, Salesforce, and Pipedrive. Plans start at around $49/month, and a 14-day free trial is available.

The catch: Snitcher identifies companies, not individuals. If person-level LinkedIn profiles were the core reason you used RB2B, you will need to pair Snitcher with a contact enrichment tool like Apollo or Clay.

2. Warmly: Best for Real-Time Sales Triggers

Why we picked it: Warmly combines website visitor identification with real-time intent signals and built-in outreach automation. When a target account lands on your pricing page, Warmly can trigger a Slack alert, enrich the contact, and push them into a sequence without a human in the loop.

Best for: Sales-led teams running outbound sequences who want to act on website intent the moment it happens.

Key feature: Warmly layers multiple data providers (including Clearbit, Bombora, and 6sense intent data) into a single enriched visitor profile. This means you are not dependent on one data source for match rates.

The catch: Warmly's full feature set sits behind a paid plan starting at $700/month. There is a free tier, but it caps at 500 visitors per month, which limits usefulness for teams with meaningful traffic volumes.

3. Koala: Best for Product-Led and PLG Teams

Why we picked it: Koala was built specifically for product-led growth companies. It connects website behaviour, product usage data, and intent signals into a single view, so your sales team can see not just who visited your site but which free users are showing buying signals inside the product.

Best for: PLG SaaS companies with a free trial or freemium model where the handoff from product engagement to sales conversation matters.

Key feature: Koala's "intent signals" layer tracks behaviour across your site, your docs, and your product simultaneously. A free user who visits the pricing page three times and invites two colleagues is flagged as a high-priority outreach target automatically.

The catch: If you are not running a product-led motion, Koala is overkill. The product-usage layer adds no value to a pure marketing site.

4. Leadfeeder (now Dealfront): Best for CRM-Connected Pipelines

Why we picked it: Leadfeeder has been identifying website visitors since 2012 and was acquired by Dealfront to form one of the largest B2B data networks in Europe. It offers reliable company-level identification, deep CRM integrations, and a free plan that covers up to 100 companies per month.

Best for: Teams already using HubSpot, Salesforce, or Pipedrive who want visitor data to flow directly into existing deal workflows without manual export.

Key feature: The free Leadfeeder plan (called Dealfront Free) shows the last 100 identified companies with a 3-day data history. Paid plans start at $99/month and remove the data cap.

The catch: Like Snitcher, this is company-level identification, not person-level. EU traffic identification is strong given Dealfront's European data network, but US match rates can be lower than RB2B's core use case delivered.

5. Factors.ai: Best for Multi-Touch Attribution Alongside Visitor ID

Why we picked it: Factors.ai does visitor identification and connects it to a full account analytics layer. You can see which companies visited, which campaigns brought them, how many touchpoints they had before converting, and where they dropped off. Most visitor ID tools give you the "who." Factors.ai gives you the "who" and the "why."

Best for: Demand generation and marketing teams that need to prove pipeline contribution from specific channels, not just hand a list of company names to sales. If you're comparing specialist support options for attribution, PPC, and pipeline reporting, SaaS Hackers also has a list of the best B2B SaaS performance marketing agencies.

Key feature: Factors.ai's account journey view maps every touchpoint an account had across paid, organic, and direct channels before they ever filled out a form. This is genuinely useful for optimising budget allocation.

The catch: The attribution layer adds complexity. If your team just wants a simple Slack alert when a target account visits, Factors.ai is more tool than you need.

6. Clearbit / Breeze Intelligence: Best for HubSpot-Native Teams

Why we picked it: Clearbit was acquired by HubSpot and rebranded as Breeze Intelligence. If your team runs on HubSpot, Breeze Intelligence enriches contact and company records natively inside the CRM, including identifying anonymous website visitors and matching them to known HubSpot contacts.

Best for: Teams that live in HubSpot and want visitor enrichment without managing a separate tool or data pipeline. If implementation support is part of the decision, you can review the top B2B SaaS HubSpot agencies or browse B2B SaaS HubSpot experts.

Key feature: Breeze Intelligence uses Clearbit's underlying data (one of the largest B2B enrichment datasets available) and surfaces it directly in HubSpot contact and company records. No CSV exports, no manual matching.

The catch: Breeze Intelligence is priced on a credit model inside HubSpot, and costs can escalate quickly at volume. It also requires a HubSpot subscription to access, so it is not a standalone alternative.

7. 6sense: Best for Enterprise Intent Data at Scale

Why we picked it: 6sense is a full account-based marketing platform that combines anonymous visitor identification, intent data from across the web, and AI-driven account scoring. It is built for enterprise revenue teams running coordinated sales and marketing motions across hundreds of target accounts.

Best for: Enterprise B2B companies with dedicated ABM programmes and the budget to support a platform-level investment. For teams building a broader account-based motion around tools like 6sense, see these best B2B SaaS ABM agencies.

Key feature: 6sense's intent data pulls signals from third-party content consumption, review site activity, and keyword research behaviour, not just your own website. This means you can identify accounts showing buying intent before they ever visit your site.

The catch: 6sense pricing is not public and typically runs into five figures annually. There is a free tier (6sense Free) with limited features, but the meaningful functionality sits behind a significant commercial commitment.

How We Chose These Alternatives

Every tool on this list was evaluated against four criteria:

1. Identification depth: Does it identify individuals, companies, or both?
2. Geographic coverage: Does it work for US traffic, EU traffic, or both?
3. Budget accessibility: Is there a free tier or a sub-$200/month entry point?
4. Integration fit: Does it connect to the CRMs and outreach tools B2B teams already use?

Tools were excluded if they required a sales call to see pricing, had publicly documented data accuracy issues, or were primarily designed for B2C use cases.

Person-Level vs Company-Level: What You Actually Need

RB2B's core proposition was person-level identification. It pushed a LinkedIn profile, not just a company name, into Slack. That is a specific and narrow capability.

Most alternatives on this list identify companies, not individuals. That distinction matters when you are choosing a replacement.

Choose person-level tools if: Your sales motion is highly targeted, you are running outbound sequences to specific buyers, and match rate accuracy on individual contacts matters more than coverage volume.

Choose company-level tools if: You are doing account-based marketing, you have a target account list to match against, and you can use a contact enrichment tool (Apollo, Clay, Lusha) to find the right individuals once you know the company.

For most teams, company-level identification paired with a lightweight enrichment workflow delivers better results than person-level identification alone, because the company match rates are significantly higher and the data is legal to use across both US and EU jurisdictions.

US vs EU Traffic: Why Geography Matters

RB2B was built primarily for US traffic. Its match rates for European visitors were consistently lower, and GDPR compliance for EU visitor identification was a persistent concern.

If a meaningful share of your traffic comes from the UK, Germany, the Nordics, or the rest of Europe, tools built on European data networks will outperform RB2B even on its best day:

• Leadfeeder / Dealfront has the strongest EU company identification, built on Dealfront's European B2B database.
• Snitcher covers both regions with competitive match rates.
• Factors.ai and Warmly both operate across geographies but are US-first in their data sourcing.

If your traffic is 90% North American, this is less of a factor. If you are a European SaaS company or sell into both markets, geography should be your first filter when choosing.

Quick Comparison: RB2B Alternatives at a Glance

FAQs

What is the best free RB2B alternative? Leadfeeder (Dealfront Free) is the most functional free option available right now. It identifies up to 100 companies per month with a 3-day data history at no cost. Warmly's free tier covers 500 visitors per month, which suits early-stage teams. Both are company-level tools, not person-level like RB2B's original free plan.

Why did RB2B remove its free plan? RB2B has not published a detailed public explanation, but the move aligns with a standard SaaS growth pattern: use a free tier to build an audience, then convert that audience to paid as the product matures. The free plan drove significant word-of-mouth growth for RB2B, but person-level data enrichment has real per-unit costs that make a perpetual free tier difficult to sustain at scale.

Can any tool replicate RB2B's person-level LinkedIn identification? Warmly comes closest, combining company identification with individual contact enrichment from multiple data sources. Koala also surfaces individual-level signals for product-led teams. No tool currently replicates the exact RB2B workflow of pushing a LinkedIn profile directly to Slack from a free plan, but Warmly's paid tier delivers comparable (and in many cases richer) person-level data.

Is RB2B GDPR compliant? RB2B's identification method relies on US-based data and is designed for US traffic. Its compliance posture for EU visitors has been questioned by several data privacy practitioners. If you handle EU personal data, tools built on GDPR-compliant European data infrastructure (such as Leadfeeder / Dealfront or Snitcher) carry significantly lower compliance risk. Teams working through privacy, attribution, and channel mix decisions may also find SaaS Hackers' piece on the carbon footprint of digital advertising useful for broader digital strategy context.

What is the best RB2B alternative for a small B2B SaaS team on a tight budget? Snitcher at $49/month is the strongest option for budget-conscious teams that need reliable company-level identification across both US and EU traffic. Pair it with a free Apollo or Clay account to enrich company records with individual contacts, and you have a functional outbound pipeline trigger for under $100/month total.
