Warmly vs Clearbit: Which Visitor Identification Tool Is Better in 2026?
Warmly and Clearbit both help you identify anonymous website visitors, but they've taken very different paths. Warmly is a standalone visitor identification and intent data platform with a free tier, AI chatbot, and outbound orchestration features. Clearbit was acquired by HubSpot in November 2023 and rebranded as Breeze Intelligence—it now lives inside HubSpot as an enrichment and visitor ID add-on. If you're choosing between them, the deciding factor is usually whether you're locked into HubSpot or not.

Pricing comparison
| Warmly | Clearbit (Breeze Intelligence) | |
|---|---|---|
| Free tier | $0/mo (500 visitors, 10 intent signals/week) | None (HubSpot free CRM has no enrichment) |
| Entry paid | ~$1,250/mo ($15,000/yr) — TAM tier | HubSpot Starter ($20/mo) + 100 credits (~$30/mo) |
| Mid tier | ~$2,500/mo ($30,000/yr) — Inbound tier | HubSpot Pro ($800+/mo) + 1,000 credits (~$150/mo) |

| Cost per credit | N/A (visitor-based) | ~$0.15–$0.30 depending on volume |
At the free tier, Warmly wins by default. Once you move to paid plans, the comparison shifts: Clearbit via HubSpot Starter + credits can be significantly cheaper than Warmly's $15,000/year minimum. But Warmly's paid tiers include orchestration and AI features that HubSpot charges separately for. The right choice depends on how much you need beyond basic visitor identification.

Your company gets 2,000 monthly visitors and uses Salesforce. You want to identify who's visiting your site. Which tool should you choose?
Correct! Clearbit now requires HubSpot, so it won't work with Salesforce. Warmly integrates with both Salesforce and HubSpot, and you can start with the free plan to test it.
Clearbit (Breeze Intelligence) requires a HubSpot subscription and won't integrate with Salesforce as a standalone tool. Warmly works with both CRMs and has a free plan.
Who should choose Warmly
- Teams that want to try visitor identification for free before committing
- Companies using Salesforce (or both Salesforce and HubSpot)
- Revenue teams that want AI chatbot and outbound orchestration built in
- Organizations that value multi-source intent data (Bombora + LinkedIn + first-party)
- Mid-market companies with budget for the $15K/year paid tier and 1,000+ monthly visitors
Who should choose Clearbit
- Teams already on HubSpot who want native enrichment and visitor ID
- Companies that need deep firmographic and technographic data for account scoring
- Marketing teams that want form shortening to improve conversion rates
- Small teams on HubSpot Starter who just need basic enrichment credits
- US-focused businesses where Clearbit's data accuracy is strongest
You're a small HubSpot Starter team ($20/mo) and want to enrich 100 leads per month. What's the most cost-effective option?
Right! If you're already paying for HubSpot, adding Breeze Intelligence credits (~$30/mo for 100 credits) is far cheaper than Warmly's $15K/year paid tier. Warmly's free plan only covers visitor identification, not enrichment.
Warmly's free plan covers visitor identification, not enrichment. For lead enrichment on HubSpot, Breeze Intelligence credits at ~$30/mo are the most cost-effective option if you're already a HubSpot customer.
A simpler alternative: MentionAgent
Both Warmly and Clearbit focus on identifying who visits your website—then leave it to you to convert them. MentionAgent takes a different approach entirely. Instead of waiting for prospects to find your website and hoping to identify them, MentionAgent proactively finds relevant prospects across the web and reaches out to them automatically.
No visitor tracking pixel. No minimum traffic threshold. No CRM lock-in. MentionAgent monitors the web for relevant conversations and prospects, writes personalized outreach, and follows up—all for a flat $99/mo. If your site doesn't get 1,000+ monthly visitors (which most B2B sites don't), visitor identification tools won't generate enough data to be useful. MentionAgent works regardless of your traffic volume.
Your B2B site gets 300 visitors per month. You want to generate leads. What's your best option?
Correct! With only 300 monthly visitors, visitor identification tools won't generate enough leads. MentionAgent proactively finds prospects and reaches out, so your traffic volume doesn't matter.
Visitor identification tools need 1,000+ monthly visitors to be effective. At 300 visitors, even perfect identification gives you a tiny pool. MentionAgent doesn't depend on traffic—it finds and contacts prospects proactively for $99/mo.
Skip the complexity
Visitor identification tools only work if you already have traffic. MentionAgent finds relevant prospects and reaches out automatically—$99/mo flat, fully automated, no visitor tracking needed.
