Knock AI vs Warmly (2025) | Full Comparison of Features, Pricing & Performance
Knock AI vs Warmly: The Ultimate 2025 Comparison for Real-Time B2B Sales Teams
TL;DR: Knock AI vs Warmly (2025 Overview)
Warmly takes a signal-led outbound approach. It identifies in-market buyers using intent data and enrichment, then automates outreach through email, LinkedIn, and web-chat workflows. Rather than engaging in real time, it prioritizes scoring, routing, and outbound automation, making it well-suited for revenue teams that focus on nurturing signals over live conversations.
Knock AI, in contrast, is built for instant engagement. Unlike tools that capture intent and chase later, Knock AI captures B2B buyers the moment they show interest, turning anonymous visitors into real conversations across Slack, LinkedIn, WhatsApp, and website chat. Its strength lies in multi-channel presence, real-time qualification, contact & company enrichment, native CRM integration, and AI-powered follow-up that keeps the momentum alive.
In this guide, you’ll find a complete side-by-side comparison of Knock AI and Warmly, covering core features, pricing transparency, buyer-engagement philosophy, and migration insights, so you can confidently choose the platform that best fits your GTM motion in 2025.
Why Buyer Intent Alone Isn’t Enough
Modern B2B Buying Has Changed Forever
The traditional B2B buying journey, form fill → email → meeting → demo, is collapsing.
Today’s buyers expect instant answers, multi-channel engagement, and human-like responsiveness. They don’t want to “book a meeting next week”; they want a real B2B conversation right now, often from Slack, LinkedIn, or their mobile device.
Decision-makers are also becoming harder to reach by email. They evaluate vendors asynchronously, research quietly, and expect solutions to recognize them instantly when they return to a site, without being pushed. Modern buyers don’t want to be sold to; they want control and freedom in how they engage, a behavior rooted in psychological reactance.
This shift has created a new marketing reality powered by real-time intent data, visitor de-anonymisation, and AI-assisted sales conversion, where winning teams focus on timing, relevance, and autonomy rather than pure outreach volume.
Where Warmly Fits and Where It Falls Short
Warmly built its platform around a signal-first model: detect B2B buyer intent signals, de-anonymise visitors, and trigger personalized outreach sequences across email, LinkedIn, and chat. It’s a strong approach for identifying who’s in-market and arming sales teams with enriched contact data.
But that same workflow creates delay.
Warmly identifies the right buyer, then hands them off to an automated nurture sequence that unfolds over hours or days. The problem is, that handoff can reduce conversion potential by more than 90%. In fast-moving sales cycles, every delay means lost attention. When an inbound lead moves to an outbound sequence, most chances you’ve already lost them.
Warmly excels at intent recognition but leaves a critical gap between discovery and dialogue, the moment when a buyer’s curiosity is highest.
How Knock AI Solves the Engagement Gap
Knock AI flips the funnel from “signal → nurture” to “signal → conversation.”
Instead of waiting for a lead to respond to an email, Knock’s AI agents open real-time B2B conversations directly in the buyer’s channel of choice, whether it’s Slack, the website, or LinkedIn.
Every anonymous visitor is instantly enriched through Knock Reveal, identifying name, title, company, and LinkedIn profile. That enriched context feeds Knock Intent, which scores readiness to buy in real time based on first-party engagement signals and on-site behavior.
Knock AI also detects buyer intent from first-party messages, helping teams understand not only who is visiting but why they’re interested. Qualified visitors are then automatically routed to the right rep or engaged by Knock’s AI Agent to answer questions, qualify needs, and even book meetings on the spot.
This shift from delayed outreach to live, multi-channel engagement is what drives faster pipeline velocity, higher response rates, and true real-time sales conversion.
In short: Warmly recognizes interest. Knock AI converts it.
Feature-By-Feature Comparison: Knock AI vs Warmly
Feature / Solution
Knock AI
Warmly
Knock AI Advantage
Visitor Identification / De-Anonymisation
Knock Reveal: Identifies anonymous website visitors and off-site engagers (e.g., Slack, LinkedIn, or shared content interactions). It enriches each profile with contact + company data, routes qualified leads directly to Slack/CRM, and unifies engagement data across channels.
Warmly AI Data Agent: Person-level de-anonymisation of website visitors, 1st/2nd/3rd-party signals. Example: reveals ~15% of contacts and ~65% of companies.
Knock AI includes both de-anon + routing + chat engagement in one flow, fewer steps between identification and engagement.
Real-Time Intent Scoring
Knock Intent: Analyzes real engagement signals, clicks, page views, message interactions, and repeat visits, in real time. It assigns dynamic intent scores, routes high-intent leads instantly, and triggers AI-driven workflows for qualification or outreach.
Warmly Real-Time Person-Level Intent Signals: Monitors web behaviour + job changes + social + 3rd-party signals to score contacts.
Knock AI emphasizes faster lead qualification and routing the moment intent is detected, less delay.
Lead Engagement Channels
Multi-channel conversation: Website chat + Slack + LinkedIn + other channels. Knock Chat and Knock Scheduling let visitors engage in their preferred channels instantly. This DM-style selling approach delivers up to 86% reply rates and reduces time from click to opportunity by 30%.
With AI Nurture Agent, Warmly supports website chat + email + LinkedIn connection & messages + live video chat in higher tiers.
Knock AI offers built-in multi-channel & real-time B2B conversation upon intent rather than relying heavily on sequential outreach.
AI Qualification & Chat Automation
Knock AI Agent (AI SDR): Qualifies leads, answers visitor questions, books meetings, and routes to human or AI. The agent matches the tone of voice and adapts messaging style to each buyer’s behavior. It can also reply, qualify, route, and send LinkedIn outreach messages automatically, maintaining momentum and context across channels.
With AI Inbound Agent, Warmly includes AI chatbots for inbound, automated email/LinkedIn outreach sequences via “Orchestrator”.
Knock AI’s flow centres on the B2B conversation instantly, maintaining momentum; Warmly’s automation often begins after identification.
Automation & Orchestration
KnockAI supports automated follow-up on LinkedIn and emails (Knock Outreach) and routing workflows: Enrich → score → route → chat/meet.
Warmly describes itself as an "autonomous revenue orchestration” platform: signal-based triggers, auto-sequences for email/LinkedIn/chat.
Knock AI integrates the full funnel from identification to conversion into one streamlined flow; Warmly emphasises signals → nurture.
CRM & Integration
Knock AI enriches contact and company data in real time, based on the most up-to-date information about the lead and their organization, and automatically pushes it into CRM. Knock CRM supports two-way sync, routing, and continuous auto-updates of records.
With AI MarOps Agent, Warmly integrates with CRM, marketing automation, LinkedIn ads; uses data sync to feed outreach workflows.
Knock AI emphasises minimal friction: identify, chat, route, sync in one system; Warmly often requires setting up multiple layers.
Pricing Transparency
Public pages emphasize removing form-fills and enabling instant routing. Pricing starts from USD 700 per month, scaling with feature depth and user volume. Full tiers aren’t listed; detailed pricing is shared during demo or consultation.
Warmly public pricing: Free plan (500 visitors/month) for de-anon + proof of concept; Paid tiers: AI Data Agent starts ~$10,000/yr (~$833/mo) for 10,000 credits; Add-on tiers up to ~$25,000/yr for full features.
While both require B2B sales conversation for enterprise, Knock AI’s messaging emphasises faster ROI; Warmly’s published starting price is relatively high and usage-based, Knock AI likely more accessible for faster adoption.
Best For
Demand-rich B2B teams losing deals to friction and wasted time on non-qualified leads. Knock AI helps convert more pipeline in less time by enabling instant engagement, real-time qualification, and multi-channel conversations without form-funnels.
Revenue/RevOps teams focused on sophisticated signal stacks, large datasets, prioritising lead scoring and automated outreach as main motion.

That single difference compresses the sales cycle from days to minutes, making Knock AI the go-to choice for real-time sales conversion, multi-channel engagement, and AI-driven pipeline velocity.
Warmly was built around a data-driven motion: detect who’s in the market, then automate the outreach. Its foundation lies in B2B buyer-intent signals, website visits, firmographic patterns, job changes, and social interactions. Using its AI Data Agent and AI Revenue Orchestration Platform, Warmly connects these digital breadcrumbs to identify “warm leads,” enrich them, and then queue them for follow-up via email, LinkedIn, or chat workflows.
It’s a sophisticated, signal-first system best suited for teams managing large data stacks and complex RevOps environments. These organizations rely on granular lead scoring, multi-touch automation, and structured outbound sequences.
However, this model has an inherent limitation: time. Once intent is detected, the system still relies on scheduled outreach, meaning minutes or hours can pass before the prospect is actually engaged. In fast-moving buying cycles, that delay often determines who wins the deal.
Warmly’s strength: identifying interest at scale. Warmly’s trade-off: engagement happens later, not live.
Knock AI flips the funnel entirely. Instead of scoring buyers and sending them to a queue, it engages them the moment intent appears and does the qualification in real-time. Its belief is simple yet powerful:
“You must meet buyers where they are, when they’re ready, in the channel they already use.”
Through Knock Reveal, Knock Intent, and the Knock AI Agent (AI SDR), teams can move from anonymous visit → identified contact → live conversation in seconds, on Slack, LinkedIn, WhatsApp, or website chat. AI and humans collaborate seamlessly: Knock AI’s agent qualifies, answers questions, and books meetings instantly, while enriched data flows automatically into HubSpot or Salesforce.
This conversation-first philosophy focuses on speed, relevance, and immediacy. By removing friction, no forms, no waiting, no nurture delays, Knock AI creates human-like buying experiences that feel personal and responsive, not robotic.

Summary Insight
Both platforms help revenue teams interpret buying intent, but they act on it differently:
Warmly listens for intent signals and prepares an automated outreach.
Knock AI reacts instantly, starting a conversation while interest is hot.
In 2025’s attention-scarce B2B landscape, speed and immediacy outperform automation alone, and that’s where Knock AI’s conversation-first philosophy wins.

Discussions among B2B practitioners echo similar themes.
Data Transparency: Users question how Warmly performs person-level de-anonymization, noting it depends heavily on CRM access and known 1P data.
Accuracy & Matching: Some marketers observed mismatches between IP → contact mapping and LinkedIn profiles, suggesting a “likely-contact” rather than confirmed identity model.
Comparisons: Warmly is frequently compared to tools like RB2B and LeadPipe, praised for interface polish but criticized for lower match rates and privacy ambiguity.
One senior marketer summarized:
“Warmly identifies company-level visitors accurately, but person-level data can be noisy. Great intent alerts, not always precise identities.”
Weaknesses: inconsistent enrichment accuracy, higher entry pricing (~ $10 k / yr), occasional account or plan friction.
Knock AI Advantage:Knock AI pairs comparable enrichment accuracy with instant engagement, turning identified visitors into live Slack or chat conversations before competitors can email them.
Migration Guide: Switching from Warmly to Knock AI
Step 1: Export from Warmly
Export contacts (with any enrichment fields), and audience/sequence definitions you want to keep as references.
If available in your plan, also export website visitor/event data or use your CRM/CDP as the system of record.
If the specific export location differs by plan, follow Warmly’s in-app instructions or contact their support to obtain the latest export options.
Artifacts to keep handy
CSVs of contacts/companies (with IDs, titles, emails, LinkedIn, firmographics, tags/segments).
Notes/screenshots of nurture sequences, routing rules, and audience filters you intend to replicate or improve.
Step 2: Import into Knock AI
CRM-led sync (recommended): Connect Knock AI to your CRM (e.g., HubSpot or Salesforce). Existing records and fields map through your CRM, preserving history and ownership.
Direct import (optional): If needed, upload CSVs to Knock AI.
Enable Knock Reveal so returning visitors are enriched (contact + company), and confirm field mappings for enrichment write-back to your CRM.
Checklist
CRM connected and authenticated
Field mapping confirmed (standard + custom)
Channels connected (website chat, Slack; add others you use such as LinkedIn integrations)
Keep Warmly active while you turn on Knock AI for the same traffic.
Compare like-for-like metrics you already track, such as:
Time to first response/engagement
Qualified conversations or meetings created
Lead acceptance rate / pipeline created
Show rate and cycle time (if you track these)
Use these observations to tune Knock AI Agent (AI SDR) prompts, routing, and follow-ups.
Tip: hold the comparison period steady and avoid changing upstream traffic sources during the test so results are clean.
Step 4: Deactivate Warmly & Optimize Knock AI
When your team is comfortable with results, turn off Warmly sequences and remove any duplicate triggers.
Centralize engagement in Knock AI (identify → enrich → converse → schedule → CRM sync).
Continue refining conversation flows, qualification logic, and SLAs inside Knock AI so reps and AI hand off cleanly.
What Typically Transfers (via CRM or CSV)
Contacts & companies with enrichment fields
Ownership/territory and relevant tags
Historical notes/activities that already live in your CRM
Custom fields you map during setup
Note: exact exportability of raw visitor/session data from Warmly depends on plan features and current product capabilities. Use your CRM/CDP as the canonical history where possible.
What You’ll Re-configure in Knock AI
Channel connections: website chat, Slack (and any other channels you use)
Routing rules: owner/region/ICP logic, handoff to human vs AI
AI Agent prompts & guardrails: FAQs, qualification criteria, booking rules
Follow-ups: post-chat emails/messages and CRM task creation
Field mapping: ensure enrichment updates the correct CRM fields without overwriting source-of-truth data
Warmly is designed for signal-first automation, it identifies in-market buyers and triggers outreach sequences.
Knock AI, in contrast, is conversation-first: it turns those same buyer signals into live, real-time interactions across Slack, LinkedIn, WhatsApp, and web chat. The result is faster engagement, higher show-rates, and shorter sales cycles.
Q2. Does Knock AI include visitor identification and data enrichment like Warmly?
Yes. Knock Reveal automatically de-anonymizes visitors, enriching contact and company data (name, title, LinkedIn, firmographics) before routing them to Slack or CRM. It delivers the same data depth as Warmly’s Data Agent, but activates it instantly for conversation.
Q3. How long does it take to switch from Warmly to Knock AI?
Most teams complete migration in under two weeks.
Knock AI provides guided onboarding: export contacts and workflows from Warmly, import them directly or via CRM, then run both in parallel to compare metrics. Large accounts (1 000 + contacts) get white-glove migration support free of charge.
Q4. Does Knock AI integrate with HubSpot, Salesforce, and other CRMs?
Yes. Knock AI’s native HubSpot and Salesforce integrations automatically sync enriched contact data, map transcripts, and update records in real time, no manual uploads. You can also connect with other major CRMs through open APIs or Zapier-style connectors.
Q5. Which platform is better for small and mid-market teams?
Knock AI. With plans starting around USD 700 / month, it delivers enterprise-grade engagement without the enterprise price. Warmly’s entry point starts near USD 10 000 / year, making it more suitable for large RevOps or data-heavy organizations.
Q6. Does Warmly offer real-time conversations like Knock AI?
Some teams run Warmly for high-level signal monitoring while using Knock AI for instant engagement and qualification. However, most migrate fully to Knock AI once they see conversion gains from real-time conversations and multi-channel workflows.
Q8. How does Knock AI improve pipeline velocity compared to Warmly?
By engaging visitors in-session rather than hours later, Knock AI reduces the typical response lag (42 hours → under 60 seconds). That immediacy translates into 2-3× faster pipeline velocity and higher demo-show rates across B2B sales teams.
Q9. Is Knock AI secure and GDPR-compliant?
Yes. Knock AI follows strict data-handling practices, enrichment data is sourced compliantly and CRM integrations respect regional privacy standards including GDPR and CCPA.
Q10. Can I try Knock AI before committing long-term?
Yes. You can book a personalized demo or limited-access pilot directly through the Knock AI website to test real-time engagement flows, Slack integrations, and enrichment accuracy.
