Clearbit vs Warmly

Clearbit and Warmly both focus on website visitor identification but serve different needs in the B2B sales cycle. Clearbit specializes in data enrichment and buying intent signals, now part of HubSpot's ecosystem with enterprise pricing starting at $12,000 annually. Warmly provides AI-powered revenue orchestration for contact-level visitor identification with automated multi-channel outreach, offering a free tier and custom growth pricing.

The key distinction lies in their approach: Clearbit excels at providing comprehensive firmographic data (100+ attributes) and intent signals integrated with HubSpot and Salesforce, while Warmly goes beyond identification to enable automated outbound engagement through email, LinkedIn, and chat. Both tools lack dedicated customer support inbox functionality, focusing instead on lead generation and prospecting.

Clearbit's strength lies in data depth and accuracy, offering 100+ B2B attributes per record including employee counts, revenue estimates, NAICS/GICS/SIC codes, technology stack detection, and buying intent signals. The Clearbit Reveal feature identifies anonymous website visitors at the company level with up to 95% match rates, aggregating data from 250+ sources. Native HubSpot and Salesforce integrations enable real-time record enrichment, and the platform supports dynamic form shortening to improve conversion rates.

Warmly takes visitor identification further by de-anonymizing at the contact level rather than just company-level detection. This granularity allows sales teams to reach out to specific decision-makers. The AI-powered chatbot and automated outreach capabilities enable coordinated multi-channel engagement through email, LinkedIn, and chat simultaneously. Intent signals from multiple third-party sources provide comprehensive buyer readiness insights.

The fundamental difference is Clearbit's enrichment-only approach versus Warmly's outbound orchestration focus. Clearbit provides richer data but no engagement tools, while Warmly enables automated action based on visitor identification. Both tools lack the customer support inbox functionality that would nurture relationships beyond the initial outreach phase.

Clearbit uses a credit-based pricing model with no public pricing tiers, requiring contact with sales. Enterprise pricing typically ranges from $12,000 to $50,000+ annually based on API call volume, number of enrichment records, and features enabled (Reveal, Enrichment, Prospector). Credits are consumed per record or API call, creating budgeting complexity, and overage charges can add up quickly. The acquisition by HubSpot has positioned Clearbit primarily for large organizations.

Warmly offers a free plan for basic visitor tracking with limited intent signals and core integrations. Growth and Enterprise plans require custom sales contact, indicating usage-based pricing that scales with team size and feature requirements. While the free tier provides entry-level access, teams needing advanced de-anonymization, AI chatbot capabilities, and multi-channel outreach should expect enterprise-level pricing.

Both tools position themselves for B2B enterprise teams with opaque pricing that requires sales engagement. Traditional per-agent or credit-based pricing models can create unpredictable costs as usage grows, especially compared to modern flat-rate alternatives.

Choose Clearbit if: You're an enterprise B2B company needing deep data enrichment integrated with HubSpot or Salesforce, require comprehensive firmographics at scale, or have significant budget for data infrastructure.

Choose Warmly if: Your team needs contact-level visitor identification with automated multi-channel outreach, you want AI-powered engagement across LinkedIn and email, or you prefer a free entry tier before scaling to paid plans.

Clearbit serves enterprise B2B companies requiring comprehensive data enrichment and intent signals integrated with their existing CRM stack, while Warmly focuses on outbound sales teams who want automated visitor identification with multi-channel engagement. Both tools excel at finding potential customers but stop short of providing the customer support infrastructure needed to nurture relationships.

For teams seeking both lead capture and customer support in one platform, Converge provides visitor tracking, UTM attribution, and lead scoring alongside unified inbox support across WhatsApp, Telegram, Messenger, Zalo, Discord, and more, all for $49 monthly flat rate. This eliminates tool fragmentation and provides predictable costs regardless of team size or conversation volume.
