Website Intent & Visitor Identification
Warmly Review
Turn anonymous website visitors into qualified pipeline in real-time.
The best all-in-one visitor identification platform for B2B SaaS teams that want to act on intent signals immediately.
What makes it different
Only platform that combines visitor identification, AI chat engagement, and real-time sales routing in one tool.
Our experience
I have implemented Warmly across multiple client engagements and it consistently delivers the fastest time-to-value of any tool in our stack. One client went from zero visitor identification to booking 3 meetings in their first week. The real-time Slack alerts changed their sales team's behavior overnight. Instead of waiting for inbound form fills, reps started responding to pricing page visitors within minutes. The AI chatbot is a bonus that most teams underestimate. It handles after-hours visitors and qualifies them before a human ever gets involved. Setup takes about a day if your CRM is already clean, and you will start seeing identified visitors within hours of installing the script.

Who it is for
Best for: B2B SaaS teams ($2M-$50M ARR) with active SDR/AE teams who want an end-to-end platform that identifies website visitors, scores their intent, and routes the hottest ones to reps in real-time. Especially strong if you are losing deals because you do not know who is on your site.
Not for: Very early-stage startups with minimal website traffic (under 1,000 monthly visitors) or companies without a sales team to act on the alerts. If you just need basic person-level data and already have outreach tools, RB2B at a lower price point might be a better starting point.

Frequently asked questions
How does Warmly identify website visitors?
Warmly uses a combination of reverse IP lookup, cookie matching, and third-party data partnerships to identify companies and individuals visiting your website. At the company level, it matches IP addresses to known business networks. At the person level, it cross-references behavioral signals with professional data to identify likely visitors from those companies.
What identification rate can I realistically expect from Warmly?
Warmly reports up to 65% company-level identification for mid-market B2B traffic. In practice, most of our clients see 40-55% depending on their traffic mix. Enterprise B2B companies with predictable traffic patterns see higher rates. Consumer-heavy or VPN-heavy traffic will see lower rates. Person-level identification is typically 15-25%.
Does Warmly work with my CRM?
Warmly integrates natively with HubSpot and Salesforce via OAuth. It also connects to most other tools via Zapier, Make, or webhooks. CRM records are created or updated automatically when a visitor is identified, and you can configure which fields get populated.
How does the AI chatbot work on Warmly?
The AI chatbot engages visitors based on rules you set. It can greet ICP visitors on high-intent pages like pricing, ask qualifying questions, answer common objections, and book meetings directly on your team calendar. It works 24/7, which is particularly valuable for after-hours traffic when no rep is available.
Is Warmly GDPR compliant?
Yes. Warmly primarily uses company-level IP-to-company matching, which falls under legitimate business interest under GDPR. Person-level data comes from publicly available professional information. Warmly includes consent management features and complies with GDPR, CCPA, and other privacy regulations.
How does Warmly compare to RB2B?
Warmly is a full-platform solution with company and person identification, real-time alerts, AI chatbot, CRM integration, and intent scoring. RB2B focuses specifically on person-level LinkedIn matching at a lower price point. Choose Warmly for complete identification-to-engagement workflow; choose RB2B if you only need the data feed and already have outreach infrastructure.
What does Warmly cost?
Warmly pricing starts at approximately $700/month on a tiered SaaS model. Pricing scales based on monthly identified visitors and features. There is no free tier, but they offer demos and trials. For most B2B SaaS companies, the ROI math works out within the first month if you have decent website traffic and an active sales team.
