The answer up front: Warmly de-anonymizes website visitors at the person level and converts them with AI chat - priced from $10,000/year, no free plan on the current page. Two things send people to this page in 2026: the price, and the June 30, 2026 announcement that HubSpot is acquiring Warmly (their words: contracts and pricing unchanged for now; long-term, the product folds into HubSpot). If you are not a HubSpot shop, the independence question is real. The short version: RB2B for cheap person-level visitor alerts (US traffic), Amplemarket for intent signals wired into sequences, and Valley (that is us) if the point was never the dashboard - it was turning warm signals into researched outreach that gets replies.
Disclosure: Valley makes one of the tools in this comparison. We have marked our entry clearly, and where the other tool is the better fit for your motion, we say so.
How we know this category: we run outbound for 1,000+ LinkedIn accounts and have sent 30M+ messages. Competitor facts below are dated September 2026 and drawn from their published pages plus named third-party reviews.
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%.

Tool | Price (Sep 2026) | What it identifies | Best for |
|---|---|---|---|
Warmly | From $10,000/yr | Person-level visitors + intent (being acquired by HubSpot) | Inbound chat conversion on real traffic |
Valley | $149/mo quarterly · $199 monthly | LinkedIn signals: profile viewers, post engagers, hiring, funding | Turning signals into replies (15-45%) |
RB2B | Free-$199/mo | Person-level US website visitors | Cheap visitor alerts to Slack |
Amplemarket | From $600/mo (annual) | Intent signals + contact database | All-in-one sequences + dialer |
Company-level tools (Leadfeeder etc.) | Varies | Company-level visitors | EU-compliant company ID - see our guide |
Valley (that is us) - when the goal is replies, not another dashboard
Visitor-ID tools tell you who showed intent and stop there; the pipeline math happens after. Valley closes that loop on LinkedIn-native signals - who viewed your profile, engaged your posts (or a competitor's), started hiring, just raised - qualifies each person against your ICP, researches them individually, and sends personalized outreach across LinkedIn and email. You approve every send.
Honest scope note: Valley's signals are LinkedIn-and-events based, not website-pixel based. If you specifically need to know which companies hit your pricing page, pair a visitor tool with it - our website visitor identification guide compares those tools. What Valley owns is everything after the signal: 15-45% reply rates against a category average of about 2%. $149/mo billed quarterly, 7-day trial.
RB2B - person-level visitor alerts at a tenth of the price
RB2B pipes the names and LinkedIn profiles of US website visitors into Slack from $79/month (a free company-level tier exists; person-level data left the free plan in January 2026). Pro+ at $199/month claims 35-45% person-level coverage; independent reviews report 15-30% in practice.
The hard limit is geography: RB2B is explicitly US-only for person-level identity. International traffic stays anonymous.
Amplemarket - intent signals inside an all-in-one platform
If Warmly's appeal was signals feeding outreach, Amplemarket bundles intent data, job-change alerts, a contact database, sequences, and a dialer from $600/month on an annual-only term (about $7,200/yr upfront, 2 users included).
Its G2 reviews praise the AI copy and flag two things: deliverability drops when sequences scale, and the annual-only billing that makes it a sight-unseen commitment.
The company-level route - cheaper, EU-safe, less precise
If person-level ID is overkill or non-compliant for your market, company-level identification (Leadfeeder, Albacross, and peers) shows which firms visited without naming people. We compared that whole category, with prices and the person-vs-company distinction, in our visitor tracking guide.

Is Warmly really being acquired by HubSpot?
Yes - announced June 30, 2026 on Warmly's own blog. Warmly says existing contracts, pricing, and integrations are unchanged for now, with capabilities folding into HubSpot's platform over time. If your stack is not HubSpot, factor that roadmap in.
How much does Warmly cost?
Current published plans: AI Web-Deanonymization from $10,000/yr, Inbound Chat $20,000/yr, AI Inbound Autopilot $30,000/yr, plus add-on packages at $10,000/yr each. No free plan appears on the current pricing page.
How accurate is Warmly's visitor identification?
Independent reviews put person-level identification at roughly 20-40% of traffic, varying with company size and network type - useful, not omniscient. Every vendor in this category has the same ceiling; ask for a trial on YOUR traffic.
What is the cheapest Warmly alternative?
RB2B - free for company-level alerts, $79-199/month for person-level US identification. If the goal is outreach rather than identification, Valley starts at $149/month and works from LinkedIn signals instead of website pixels.
