7 Best Warmly Alternatives for Lead Generation in 2026

Why B2B Teams Are Looking for Warmly Alternatives

Warmly built its reputation on real-time visitor identification and AI-powered chat — a strong combination for intent-driven sales teams. Its free tier supports up to 500 monthly visitors, while paid plans start at $700/month (Startup) and climb to $1,440/month (Business), with enterprise tiers priced on custom contracts. At those figures, teams expect bulletproof data quality and reliable alerting.

G2 reviewers tell a different story. Recurring complaints include inaccurate company identification (particularly for SMBs and non-US visitors), notification delays that kill the "catch them while they're live" value proposition, and a steep price-to-quality ratio once you exceed the free tier. Teams running multichannel outbound or needing person-level (not just account-level) identification often hit a ceiling Warmly can't clear.

The alternatives below range from deep B2B data platforms to lightweight visitor trackers and full AI conversion suites — each addressing a specific gap Warmly leaves open.

The 9 Best Warmly Alternatives in 2026

1. Leadfeeder (Dealfront) — Best for Company-Level Visitor Intelligence in Europe

Leadfeeder, now part of Dealfront, identifies the companies visiting your website even when they never fill out a form. Unlike Warmly's approach of layering AI chat on top of identification, Leadfeeder focuses on delivering clean, CRM-ready company data with deep intent filtering.

• Identifies visiting companies using reverse IP lookup matched against a 10M+ company database
• Filters leads by firmographics (industry, size, location) and behavioral signals (pages viewed, session length, return visits)
• Automatic CRM sync to HubSpot, Salesforce, Pipedrive, and Zoho — pushes new company visits as leads in real time
• GDPR-compliant architecture built specifically for European data regulations, a significant edge over US-first competitors
• Feed quality scoring that surfaces high-intent accounts and suppresses low-value traffic (ISPs, bots, employees)

Pricing: Free plan (limited to last 3 days of data, max 100 leads/month). Paid plans from $99/month billed annually for up to 50 identified companies per month, scaling with volume. Enterprise plans with custom feeds typically run $500–$1,500+/month.

Best for: European B2B teams that need GDPR compliance and clean account-level data without the chatbot overhead.

2. Apollo.io — Best for Outbound Prospecting + Visitor Intent Combined

Apollo.io goes beyond visitor identification into a full sales intelligence and engagement platform. Where Warmly surfaces who's on your site, Apollo tells you who to go after — and gives you the tools to reach them across email, phone, and LinkedIn.

• 275M+ contact database with verified emails and direct dials — significantly larger than Warmly's enrichment layer
• Website visitor tracking with intent signals tied directly to prospect records in the Apollo database
• Automated sequences (email + LinkedIn + call tasks) triggered by visitor activity
• AI-generated email personalization using prospect's job change signals, news mentions, and technographic data
• Built-in A/B testing for sequences, with analytics on reply rates, open rates, and meeting conversions

Pricing: Free plan (limited credits). Basic $49/user/month, Professional $79/user/month, Organization $119/user/month (all billed annually). Teams typically get 10x more outreach capability per dollar compared to Warmly's business tier.

Best for: SDR-heavy teams that need both inbound intent signals and outbound execution in one platform.

3. ZoomInfo — Best for Enterprise GTM Intelligence at Scale

ZoomInfo is the market leader in B2B data and GTM intelligence. It's categorically a different product from Warmly — less focused on real-time chat engagement and more on powering the entire go-to-market motion with the richest B2B dataset available.

• WebSights module identifies anonymous website visitors at the company level with intent scoring
• Streaming intent data across 4,000+ topics shows which accounts are actively researching your category across the web
• Contact-level data including direct dials, verified emails, org charts, and technographics for 260M+ professionals
• Workflows engine automates CRM updates, lead routing, and sales alerts based on intent triggers
• Chorus conversation intelligence included in higher tiers for call recording and deal coaching

Pricing: Custom contracts, typically $10,000–$25,000+/year for small teams. Enterprise deals exceed $50,000/year. No public monthly pricing — annual contracts only.

Best for: Enterprise sales teams with $1M+ ARR targets that need the deepest B2B data available and can justify the investment.

4. Cognism — Best for GDPR-Compliant Phone Data in EMEA

Cognism differentiates on two things Warmly can't match: phone-verified mobile numbers and genuine GDPR compliance with a do-not-call list check across 13 European countries. If your team does cold calling into European markets, Cognism is the clear winner.

• Diamond-verified mobile numbers with human confirmation — connect rates 3x higher than standard mobile data
• Bombora intent data integration shows which accounts are in active buying mode before they hit your site
• Compliant-by-design: checks against TPS/CTPS lists, CCPA opt-outs, and GDPR consent records automatically
• Browser extension for prospecting on LinkedIn, Sales Navigator, and company websites
• CRM enrichment and real-time data refresh to keep existing records clean

Pricing: Custom only, but publicly available information puts entry-level at $15,000–$20,000/year for small teams. Larger deployments typically run $30,000–$60,000/year.

Best for: UK and European sales teams running phone-led outbound programs where compliance is non-negotiable.

5. HubSpot Marketing Hub — Best for Full-Funnel Lead Generation with CRM Native Integration

HubSpot Marketing Hub addresses a different layer of the problem: rather than identifying anonymous visitors after the fact, it builds the infrastructure to convert them in the first place. Forms, landing pages, email nurture, and analytics all live in the same database as your CRM contacts.

• Live chat and chatbot builder with meeting booking — a direct functional overlap with Warmly's engagement layer
• Behavioral tracking tied to contact records: every page view, email open, and form fill attributed to the right person
• Smart content that personalizes website copy, CTAs, and forms based on visitor attributes and lifecycle stage
• Ad retargeting audiences built automatically from CRM segments
• Native integration with Breeze Intelligence (formerly Clearbit) for visitor enrichment

Pricing: Free CRM with basic chat. Marketing Hub Starter $20/month. Professional $890/month (includes automation, A/B testing, custom reporting). Enterprise $3,600/month.

Best for: Teams that want visitor identification, nurture, and CRM in one place without stitching together multiple tools.

6. Clearbit / HubSpot Breeze Intelligence — Best for Real-Time Enrichment on Known + Unknown Visitors

Clearbit, now HubSpot Breeze Intelligence, is an enrichment-first platform that appends firmographic, technographic, and contact data to both known contacts and anonymous website visitors. It's less a Warmly replacement and more a precision upgrade to your existing stack.

• Reveals identifies the company behind anonymous website sessions and pushes data to HubSpot CRM in real time
• Enriches form submissions with 100+ data points the moment someone converts — no manual research required
• Dynamic form shortening: already knows the company? Drop the "company name" field and reduce friction
• Intent signals surface when target accounts are actively visiting key pages (pricing, case studies, comparison pages)
• Audience builder creates HubSpot lists from enriched attributes for ad targeting and email segmentation

Pricing: Breeze Intelligence credits start at $50 for 100 credits (one credit per enrichment action). Practical monthly spend for active teams ranges $200–$800/month. Legacy Clearbit plans for non-HubSpot users are no longer available for new signups.

Best for: HubSpot-native teams that want to layer enrichment and intent signals onto their existing workflows without a new platform.

7. RB2B — Best for Person-Level (Not Just Company-Level) Identification

RB2B solves the problem Warmly and most IP-based tools share: they tell you the company, not the person. RB2B uses a first-party ID graph to identify individual visitors by name, LinkedIn profile, and email — pushing that data directly to Slack within seconds of a page visit.

• Identifies individual visitors (not just companies) — name, title, LinkedIn URL, and email delivered to Slack in real time
• US-traffic focused with the highest match rates for North American B2B visitors
• Slack-native delivery means no new dashboard to monitor — signals arrive where your team already works
• Zapier integration allows routing to CRM, sequences, or any other tool automatically
• No contracts, no implementation: JavaScript snippet deployed in under 5 minutes

Pricing: Free plan (100 person profiles/month). Pro $99/month for unlimited identified visitors. Significantly cheaper than Warmly's Startup tier for teams primarily needing person-level signals.

Best for: US-focused SMB and mid-market teams that want person-level signals immediately without a complex setup.

8. 6sense — Best for Account-Based Marketing with Predictive Intelligence

6sense operates at a fundamentally different layer than Warmly. Rather than reacting to who visits your site today, 6sense predicts which accounts will enter the buying cycle 30–90 days from now using third-party intent data, technographic signals, and AI-powered scoring models.

• Revenue AI assigns every account in your TAM a stage (Awareness, Consideration, Decision, Purchase) based on 40+ intent signals
• Identifies anonymous website visitors at the account level and ties sessions to CRM account records
• Advertising module targets in-market accounts on display, LinkedIn, and G2 before they engage your sales team
• Orchestration workflows trigger CRM alerts, ad suppression, and rep notifications when accounts hit target intent stages
• Integrates with Salesforce, HubSpot, Marketo, Outreach, and Salesloft natively

Pricing: Free tier available (limited intent signals). Team plan typically $40,000+/year. Growth plan $65,000+/year. Enterprise with full AI and advertising suite exceeds $100,000/year.

Best for: Enterprise marketing teams running ABM programs with $5M+ pipeline targets that need predictive intelligence, not just reactive identification.

9. Expertise AI — Best for AI Conversation + Conversion Without the Enterprise Price Tag

Expertise AI positions itself as a direct Warmly alternative for teams that want AI-driven engagement on top of visitor identification, but at a fraction of Warmly's Business tier pricing. Its standout feature is real-time microsite generation — a personalized landing experience built on the fly based on what a visitor is searching for.

• Creates hyper-personalized microsites per visitor query in real time to boost engagement and conversion rates
• Natural-language playbooks replicate your exact sales qualification workflow without coding
• Voice AI capabilities for multilingual conversations — Warmly has no comparable feature
• Identifies and enriches anonymous visitors with company, contact, and firmographic data automatically
• Instant meeting booking with intelligent routing, no-show prevention, and prospect insights
• SOC 2 Type II and GDPR compliant — enterprise security without enterprise pricing
• One-click integrations: HubSpot, Salesforce, Slack, Marketo, LeanData, Zapier, WhatsApp

Pricing: Free plan (1 AI agent, 10 conversations/month, basic visitor identification). Pro $160/month (unlimited AI conversations, voice capabilities, full visitor identification, standard team management).

Best for: SMB and mid-market teams wanting Warmly-style engagement with voice AI and microsite personalization at a lower price point.

Migration Tips When Switching from Warmly

Switching visitor identification and engagement tools requires careful sequencing to avoid losing active pipeline signals. Follow this order to minimize disruption:

• Export your historical data first. Before canceling Warmly, download all identified visitor logs, enriched contact records, and engagement history. Most CRM integrations don't back-sync historical data when you disconnect.
• Run both scripts in parallel for 2–4 weeks. Install your new tool's tracking pixel alongside Warmly's. Compare match rates on the same traffic to validate data quality before fully cutting over.
• Rebuild CRM mappings explicitly. Warmly pushes fields with its own naming convention. Tools like Leadfeeder, ZoomInfo, and Apollo use different field structures — map these in your CRM before importing to avoid duplicates and broken views.
• Reassign notification workflows. If your SDRs receive Slack alerts from Warmly, rebuild those triggers in the new tool before canceling. A gap in real-time alerts can cost high-intent accounts.
• Check contract lock-in. Warmly's paid plans are typically annual contracts. If you're mid-term, negotiate a data export SLA and confirm your cancellation date to avoid double-billing during the transition.

Compatibility Notes

• HubSpot users: Leadfeeder, Apollo, Clearbit/Breeze Intelligence, and HubSpot Marketing Hub all offer native HubSpot integrations with real-time sync. The transition is lowest-friction here.
• Salesforce users: ZoomInfo, Cognism, Apollo, and Expertise AI all support native Salesforce sync. 6sense has the deepest Salesforce Opportunity-level integration for ABM.
• Marketo users: 6sense and ZoomInfo have enterprise-grade Marketo integrations. Expertise AI also supports Marketo natively on the Pro plan.
• European companies: Prioritize Leadfeeder (Dealfront) or Cognism — both are built for GDPR compliance. RB2B's match rates drop significantly for non-US traffic, making it a poor fit for EMEA teams.

Which Warmly Alternative Should You Choose?

The right pick depends on which Warmly limitation is blocking you most:

• Price is the problem: RB2B at $99/month or Expertise AI at $160/month give you real-time identification and engagement at a fraction of Warmly's Startup tier.
• Data accuracy is the problem: ZoomInfo or Cognism offer the highest-quality B2B data available — both validate records continuously and back their accuracy with SLAs.
• GDPR compliance is the problem: Leadfeeder (Dealfront) was architected for European compliance from day one. Cognism adds phone-verified contacts for call-led teams.
• You need outbound execution, not just identification: Apollo.io combines intent signals with a 275M contact database and built-in sequencing — one platform replaces Warmly plus your outbound tool.
• You're already in the HubSpot ecosystem: HubSpot Marketing Hub paired with Breeze Intelligence gives you native visitor identification, enrichment, and engagement without leaving your CRM.
• You're running enterprise ABM: 6sense is the only option that predicts buying intent before accounts visit your site — a fundamentally different capability than Warmly's reactive identification.

If your core use case is identifying visitors and engaging them with AI conversations, both RB2B (for person-level US identification) and Expertise AI (for AI engagement with voice and microsites) deliver comparable functionality to Warmly at 85–90% lower cost. Start with their free tiers before committing to any annual contract.
