Visitor Intelligence Comparison · 2026

Warmly.ai vs Clearbit —
Visitor Intelligence Without the HubSpot Lock-In

Clearbit became enrichment-only inside HubSpot after the 2023 acquisition — no real-time visitor alerts, no person-level ID, no standalone pricing. Warmly delivers full revenue orchestration with person-level visitor identification at $10K/yr, no HubSpot required.

The Clearbit acquisition gap
After HubSpot acquired Clearbit in late 2023, the product was folded into the HubSpot ecosystem and discontinued as a standalone platform. Teams without HubSpot lost access. Teams with HubSpot got data enrichment — but not real-time visitor identification, not person-level signals, and not sales routing. The gap Clearbit left behind is exactly where Warmly operates: identify who is on your site right now, alert the right rep instantly, and trace that visit directly to pipeline.

The real price of Clearbit
vs. Warmly

Clearbit's pricing became opaque post-acquisition — bundled into HubSpot Marketing Hub tiers that teams must upgrade to access. Add the tools you need for the capabilities Clearbit never had (real-time visitor ID, routing, alerts) and the all-in cost grows fast.

HubSpot Marketing Hub (for Clearbit access) $12–40K/yr

Enrichment-only vs. full revenue orchestration

Clearbit was built for data enrichment — appending company and contact firmographics to records. Warmly is built for revenue orchestration — identifying who's on your site, alerting the right rep, and driving pipeline attribution in real time.

What marketing leaders are saying about Clearbit

Marketing and demand gen leaders across B2B SaaS have been publicly vocal about the gap Clearbit's HubSpot acquisition created. The pattern is consistent: data quality concerns, capability limitations, and the need for a standalone alternative that actually delivers real-time visitor intelligence.

📉 Data Quality

"Marketing leaders across mid-market SaaS report noticeably degraded match rates from Clearbit's data layer after the HubSpot acquisition — with identification accuracy declining as data infrastructure priorities shifted toward HubSpot's broader platform goals."

W Warmly's identification stack is independent and purpose-built for visitor intelligence — not a secondary asset inside a CRM platform. Match rates aren't subject to third-party acquisition decisions or ecosystem consolidation pressures.
👻 The Visibility Gap

"Demand gen leaders consistently describe the same problem: hundreds of high-intent visitors — people who've viewed demos, pricing pages, and key features — where 90% are invisible. IP-based company matching tells you a company visited, but not which person or what to do next."

W Warmly deanonymizes at the person level — not just the company. When a named contact from a target account hits your pricing page, the right rep gets a Slack alert in real time, not a batch enrichment report the next morning.
🔒 HubSpot Lock-In

"Revenue leaders who relied on Clearbit as a standalone tool found themselves forced to evaluate HubSpot adoption — not because HubSpot was the right CRM for their team, but because it became the only path to access data enrichment capabilities they were previously buying directly."

W Warmly connects to the CRM you already use — Salesforce, HubSpot, or others via OAuth. Your visitor intelligence capability doesn't require a platform migration, a new CRM subscription, or a vendor ecosystem commitment.
📋 Enrichment-Only Limits

"Mid-market marketing teams note that Clearbit was always a data enrichment layer — useful for populating fields, but never designed for real-time revenue orchestration. The gap between 'knowing a company visited' and 'alerting a rep and booking a meeting' was always left to other tools."

W Warmly closes the loop from visitor to pipeline — identify, route, engage, and attribute in a single platform. No patchwork of enrichment tools, routing tools, and alert tools stitched together across multiple vendors.

Frequently asked questions

Everything teams ask when evaluating Warmly as a Clearbit alternative.

What happened to Clearbit after the HubSpot acquisition? +
HubSpot acquired Clearbit in late 2023 and folded its data enrichment capabilities into the HubSpot ecosystem. Clearbit's standalone product was effectively discontinued as an independent platform. Teams that relied on Clearbit for visitor intelligence now find that the enrichment functionality is bundled into HubSpot Marketing Hub tiers — meaning you need a HubSpot subscription to access what you previously bought separately. For teams not on HubSpot, or those who need real-time visitor identification (which Clearbit Reveal never fully delivered), the acquisition created a capability and pricing gap that has pushed many teams to evaluate alternatives like Warmly.
Does Clearbit identify anonymous website visitors in real time? +
Clearbit Reveal provided company-level IP-to-company matching — it could tell you a company visited your site, but not the specific person. It also operated as a batch enrichment tool, not a real-time alerting platform. There were no instant Slack or email alerts when a target account landed on your pricing page, no person-level identification, and no sales routing built in. Warmly provides all of this: person-level deanonymization, instant Slack alerts to the right rep, AI-assisted engagement, and direct pipeline attribution — from a single 15-minute JS snippet install.
Does Warmly work without HubSpot? +
Yes. Warmly connects to Salesforce, HubSpot, and other CRMs via OAuth — HubSpot is one option, not a requirement. Unlike Clearbit post-acquisition, Warmly is CRM-agnostic. You get the same person-level visitor identification, real-time rep alerts, and AI engagement regardless of which CRM your team uses. If your team is on Salesforce, you won't be pushed toward a stack change just to access visitor intelligence.
How does Warmly compare to Clearbit Reveal specifically? +
Clearbit Reveal matched IP addresses to company names and basic firmographics — company-level identification, no named individuals, no real-time alerting, no sales routing. Warmly goes significantly further: person-level identification (not just company), real-time Slack alerts when a named individual from a target account is on site, AI-powered engagement, and direct pipeline attribution. Match rates for Clearbit Reveal also degraded noticeably after the HubSpot acquisition. Warmly's identification layer is independent of that consolidation and purpose-built for revenue orchestration, not data append workflows.
