RB2B AI: ASK US ANYTHING
Teams are exploring Warmly alternatives due to the recent HubSpot acquisition, data accuracy issues, limited enrichment capabilities, and pricing constraints. This guide compares seven top alternatives including RB2B, Clearbit, ZoomInfo, Apollo, Lusha, Cognism, and Adapt.io for enhanced B2B lead intelligence.
When your sales team gets excited about a "hot lead" only to discover it's another bot crawling your site, you know it's time for a change. Visitor identification tools have completely transformed B2B marketing, but today's competitive industry demands more than knowing when someone visited your homepage.
Sales teams need verified decision-maker details, real-time intent signals, and data that actually converts into pipelines. Modern B2B teams require sophisticated tools that deliver actionable intelligence, not just vanity metrics like visitor counts. The era of settling for basic visitor tracking is over; it's time to explore what's next.
Warmly is great for real-time visitor identification, but teams are switching from it because of the recent HubSpot acquisition (more on that below) and other challenges like:
That’s why we’ve rounded up some of the best Warmly alternatives. These tools go beyond visitor identification with stronger data enrichment, smarter lead scoring, and seamless ABM integration.
On June 30, 2026, HubSpot announced it had agreed to acquire Warmly.
The exact contract terms weren't disclosed, but for now, Warmly says existing contracts, pricing, account teams, product experience, and integrations remain unchanged, and its agents will continue to run as they do.
If you're a Warmly customer today, there’s no immediate reason to panic. Your existing setup should continue working as before.
The bigger question is what happens over time. HubSpot says the long-term goal is to connect Warmly's context and agent capabilities across its customer platform. That's not necessarily a bad thing, especially if you already use HubSpot. But it does create a few risks for teams that don’t:
If you're already on HubSpot, the acquisition could actually make Warmly more useful through tighter native integration. But if you don't use HubSpot or want an independent source of person-level visitor data, it's worth considering alternatives now rather than waiting to see how the product evolves.
Before we dive into the details, here’s an overview:
RB2B is built to identify real decision-makers, not just accounts. By capturing names, roles, and verified contact details, the sales team gets access to actionable insights traditional ABM platforms simply don’t offer.
Unlike competitors that stop at account-level intent, RB2B supports stakeholder-level engagement in real time. A lightweight tracking pixel captures visits and pushes alerts into Slack or Microsoft Teams. With Hot Pages, teams know exactly when prospects check pricing, demos, or case studies.
RB2B also integrates with HubSpot, Salesforce, Slack, Teams, Clay, Zapier, and 50+ other apps, so you can send visitor data wherever your team needs it.
And because RB2B is a standalone platform rather than a CRM-owned product, you're not tied to any one CRM. Unlike Warmly, which is likely to be absorbed into the HubSpot ecosystem, RB2B gives you person-level visitor identification and lead intelligence without forcing you to build your entire growth efforts around a single CRM.
RB2B is free to use with unlimited team seats, 150 monthly credits, and a Slack integration. Paid plans start at at $79/mo for more credits, visitor identification with Hot Pages, and traffic insights. It also offers a Custom plan for enterprise users.
Clearbit (now part of HubSpot) helps B2B teams enrich prospect records with firmographic and technographic data, making it easier to segment audiences and personalize outreach. It enhances visibility by layering enrichment onto existing inbound leads, CRM records, and website visitor activity.
Clearbit (Breeze Intelligence) requires a paid HubSpot subscription. HubSpot Starter costs $30/mo, and Breeze Intelligence credits start at $45/mo for 100 credits. That makes the minimum effective cost about $75/mo. Credits don't roll over, and higher tiers are quote-based.
ZoomInfo offers a massive database of contacts and companies with deep enrichment, intent insights, and prospecting tools. It’s widely adopted by enterprise sales teams because of its scale and accuracy, making it a go-to for organizations that prioritize reach and advanced targeting over lightweight simplicity.
Free trial available. Prospective users must contact sales for a custom price quote.
Lusha is a sales intelligence platform designed to give sales and marketing teams direct access to verified B2B contact data. With a Chrome extension, native CRM integrations, and GDPR-compliant enrichment, it helps teams cut through noise and reach decision-makers faster.
Lusha offers a credit-based pricing model, starting with a free plan that offers 40 credits/month. Paid plans start at $37.45/user/mo (Starter, billed annually) with 4,800 credits per year. Pro runs approximately $22.45/user/mo with 3,000 credits per user. Premium's $52.45/user/mo with 7,200 credits per user. Scale plans are custom-quoted for larger teams.
Apollo.io offers a massive B2B contact database paired with built-in outreach tools. Sales teams can search verified leads, segment lists, and launch outbound sequences without leaving the platform, making it a go-to for fast, high-volume prospecting.
Apollo.io offers a free plan with 50 credits per month. Paid plans on annual billing run $49/user/mo (Basic), $79/user/mo (Professional), and $119/user/mo (Organization).
Cognism specializes in delivering compliant, GDPR-friendly data for global sales teams. With phone-verified leads and 5.6 billion international data points, it helps businesses expand across multiple continents while maintaining high standards of accuracy and trust.
Custom plans based on usage.
Adapt.io is a B2B contact and company database platform with over 200 million business contacts. It combines enrichment, lead generation, and intent signals to help teams identify and connect with the right prospects. Its Chrome extension and integrations make it a cost-effective alternative for SMBs and mid-market companies.
Adapt.io uses a credit-based pricing model with multiple tiers. The Free plan provides 25 email and enrichment credits per day and access to the Chrome extension and basic filters. Paid plans start at $49/month for more credits and added features like CSV export and priority support.
If you're ready to switch from Warmly to, say, RB2B, here are a few practical things to check before you make the move.
Before you cancel Warmly, export your historical visitor data, saved segments, and custom audience lists. Most tools in this category don't import each other's data directly, so keep a clean copy you can reference or load into your new tool's CRM.
Warmly and RB2B both use a JavaScript snippet on your site, so switching between them is straightforward. If you use Google Tag Manager, you can drop in RB2B's script and remove Warmly's tag in the same publish. If Warmly's pixel is hardcoded, just replace the snippet in your site's header.
If your team relies on Warmly for Slack notifications or CRM lead routing, set those up in your new tool before disconnecting Warmly. RB2B can also send visitor alerts to Slack and Teams, and its HubSpot and Salesforce integrations can automatically handle lead routing and workflow triggers.
If your contract allows it, run both tools on the same site for a week and compare their match rates. That's the fastest and easiest way to see whether the new tool's identification coverage works for your traffic mix before you fully commit.
Choosing the right Warmly alternative means picking a platform that helps you take action on the data you collect. Many tools provide account-level intent or basic enrichment, but they don’t always show exactly who to engage or when.
RB2B provides verified contact information, real-time alerts on high-value pages, and stakeholder-level intent tracking. This helps sales and marketing teams focus on the right prospects at the right time, reducing wasted effort and improving conversion rates.

Yes. HubSpot announced its acquisition of Warmly on June 30, 2026. The financial terms weren't disclosed, but Warmly says existing contracts, pricing, and integrations remain unchanged for now.
For existing customers, nothing changes immediately. But HubSpot's track record with acquisitions suggests the product will eventually converge into the HubSpot ecosystem. When HubSpot acquired Clearbit in 2023, the standalone product was folded into Breeze Intelligence and isn't available outside HubSpot anymore. Teams using non-HubSpot CRMs should plan for the possibility that Warmly's independent integrations will eventually be deprioritized.
The best alternative depends on what you need. For person-level website visitor identification with a free tier and no CRM lock-in, RB2B most closely matches Warmly's core use case. For a large enterprise contact database, ZoomInfo and Cognism lead the category. For budget-conscious teams that need prospecting and outreach in one tool, Apollo.io offers the best value.
Warmly's main competitors in website visitor identification are RB2B, Clearbit (now Breeze Intelligence inside HubSpot), and Leadfeeder. In the broader B2B sales intelligence space, Warmly also competes with ZoomInfo, Apollo.io, Cognism, and Lusha. But those tools focus more on contact databases and enrichment than on real-time visitor identification.
Warmly's plans start at $10,000 per year for AI Web-Deanonymization (10,000+ credits/mo). Inbound Chat runs $20,000/yr, and AI Inbound Autopilot runs $30,000/yr. Add-on packages like GTM Signals and Warm Experiences each cost $10,000/yr. There’s no free tier. By comparison, RB2B offers a free plan with 150 monthly resolutions and paid plans starting at $79/mo.
RB2B is the strongest option for non-HubSpot teams. It offers person-level visitor identification, the same core capability that sets Warmly apart. And it integrates with Salesforce, Slack, Teams, Clay, Zapier, and 50+ other tools. It's also an independent platform, so your visitor data pipeline isn't tied to a single CRM’s vendor acquisition roadmap.
Yes. RB2B offers a free plan with 150 monthly resolutions and company-level identification. Apollo.io also offers a free plan with 50 credits per month for contact prospecting.
Alert your reps, start automated outreach, and add to lead score in under five minutes.
