The short answer: choose RB2B if most of your traffic is American and you want named visitors in Slack for $79 to $199 a month. Choose Warmly if you want identification plus inbound chat, AI agents and routing, and the budget starts at $10,000 a year. Both stop at the alert: someone still has to qualify the visitor, research them and write something worth answering.
Disclosure: Valley makes one of the tools mentioned on this page and has marked its entry clearly. Where another tool is the better fit, this page says so.
Valley is an AI outbound platform that finds the people most likely to buy from you, from live buying signals, natural-language search, or your own lists, qualifies them against your ICP, researches each one, and sends personalized messages across email and LinkedIn that get 15-45% reply rates, against a category average of about 2%.

Both tools answer the same question, who is on the website, at very different prices and depths.
RB2B: named US visitors in Slack, priced for small teams
RB2B matches anonymous website visits to people and companies and posts them to Slack or Teams. The free plan resolves 150 visits a month at company level only. Starter at $79 a month adds person-level identification for US visitors (300 resolutions). Pro, from $149 a month, adds HubSpot and Salesforce sync, business email addresses, and Clay, Zapier, Apollo and webhook connections. Pro+, from $199 a month, states 35-45% coverage against 15-20% on the lower plans. Overage is 45 cents a resolution on Starter and 25 cents on Pro and Pro+, and there is a 7-day Pro trial with no card (RB2B pricing).
Watch for: person-level identification is US only, so mostly non-US traffic gets companies, not people. More options are in RB2B alternatives.
Warmly: identification plus an inbound engine
Warmly's AI Web-Deanonymization plan, from $10,000 a year, identifies visiting contacts and companies, filters them by ICP, sends real-time and Slack alerts, routes leads, syncs to the CRM and retargets by email, LinkedIn and ads. Inbound Chat (from $20,000 a year) adds an AI chatbot and live chat; AI Inbound Autopilot (from $30,000 a year) adds unlimited AI agents and automated follow-up. A GTM Signals package covering intent, hiring, funding and competitive data is a $10,000-a-year add-on (Warmly pricing).
Watch for: the quarterly view shows $4,875 a quarter for the entry plan, more than the annual figure implies, so confirm the real price with sales. On June 30, 2026 Warmly agreed to join HubSpot (announcement); teams outside HubSpot should ask about the roadmap. More options are in Warmly alternatives.
Which one for which team
Your situation | Pick | Why |
|---|---|---|
US traffic, small budget, Slack-first team | RB2B | Named visitors from $79 a month |
Mostly non-US traffic | Neither for people; a company-level tool | RB2B names people only in the US; company-level ID works globally |
High inbound volume, want chat and routing | Warmly | Identification, chat and AI follow-up in one product |
All-in on HubSpot | Warmly (watch the roadmap) | The HubSpot deal points that way |
Want outreach to the people showing intent, not more alerts | A sending layer | See below |
The wider category, with prices and the person-vs-company trade-off, is in website visitor tracking and identification tools, and third-party intent providers are in B2B intent data providers.

an unfair advantage.
When Valley fits instead (Valley's own product)
Honest scope first: Valley does not identify website visitors. Its signals come from LinkedIn and company events, such as who viewed your profile, who engaged with your posts or a competitor's, which companies are hiring and which just raised (the buying signals Valley ranks, and companies that just raised funding). Valley qualifies each person against your ICP, researches them and drafts the message in your voice. Valley is priced per seat (current prices at joinvalley.co/pricing). Starter covers LinkedIn, with email sending as an add-on; Plus, through a demo, adds 1,000 emails a month. Finding new prospects and finding and verifying emails use credits. There is a 7-day trial with a payment method.
Choose RB2B or Warmly when you specifically need to know who is on your pricing page. Add Valley when the gap is what happens after the alert: the research and the message that gets a reply. Teams comparing signal-based tools can start with the best warm outbound tools and how to find warm leads.
