Landbase vs Warmly in 2026: Outbound account discovery vs inbound visitor de-anonymization
Landbase goes out and finds companies matching your criteria. Warmly waits for visitors to show up on your site and identifies them at the person level, at roughly 20 times the entry cost.
Warmly identifies individual website visitors by name and company through de-anonymization; Landbase has no visitor identification feature and instead searches an external B2B database.
Landbase offers a genuinely free tier with 1,000 one-time credits and no credit card; Warmly has no free tier or self-serve signup, starting at $10,000/year with a required sales conversation.
Warmly requires meaningful existing website traffic to be worthwhile; Landbase has no traffic dependency since it searches an external database rather than analyzing your own visitors.
Warmly's Context Graph unifies site visits, CRM activity, email, and chat logs into one account view; Landbase has no equivalent unified account data layer, its output is a qualified list, not an ongoing account timeline.
Landbase's natural language search covers criteria like tech stack and department headcount for finding new accounts; Warmly has no discovery capability for companies that have not visited your website.
Full autonomous inbound automation on Warmly requires the $30,000/year AI Inbound Autopilot tier; Landbase's top self-serve tier is $299/month, roughly 100 times cheaper annually.
Landbase and Warmly both use AI to shortcut the "who should we talk to" problem, but they look in opposite directions to answer it. Landbase searches outward: a natural language query against a B2B database returns qualified accounts you have never contacted, with search and qualification free and only verified contact delivery costing credits, starting at $0 with no card required. Warmly looks inward at your own website traffic, de-anonymizing individual visitors down to their name and company through an identity graph, then deploying autonomous AI agents to engage them, starting at $10,000 a year with no self-serve option at all. One tool is asking "who fits our ideal customer profile out there in the world"; the other is asking "who is already here and how fast can we recognize them."
The tools at a glance
Landbase
GTM data platform that uses AI agents to find, qualify, and prioritize B2B accounts from a natural language prompt.
Landbase assumes the accounts worth targeting have not necessarily interacted with you yet, and builds its entire product around finding them. A plain-English query, covering tech stack, department headcount, and revenue range, runs through the GTM-2 Omni model, trained on more than 50 million GTM campaigns, and returns matches in seconds.
Search and AI qualification cost nothing at any tier, so a team can filter extensively before spending a credit, and enrichment only charges for verified results, an email at 1 credit and a phone number at 10, with failed lookups free. The free tier's 1,000 credits require no card, making real evaluation possible without a sales call.
Landbase has nothing to say about your existing website traffic. There is no visitor tracking, no de-anonymization, and no real-time engagement layer; it is entirely about proactively going out and finding accounts that fit a stated profile, wherever they currently are in their awareness of your product.

Warmly
AI agents de-anonymize website visitors at the person level and autonomously run inbound and outbound GTM across chat, email, and ads.
Warmly is built around a bet that the highest-intent audience is already on your site right now, and the job is recognizing them fast enough to act. Its de-anonymization layer resolves individual visitors, not just their company, cross-referencing first-party tracking with an identity graph in real time.
The Context Graph then unifies that identification with site visits, email activity, CRM records, and chat logs into one account view, and AI agents consult that graph before firing a chat message, sending a follow-up, or triggering an ad retargeting campaign. Customers cite replacing $20,000 to $40,000 a month in SDR agency spend using this model.
None of it works without real traffic to begin with, and none of it is cheap: $10,000 a year for de-anonymization alone, $30,000 a year for full autonomous automation, with no monthly plan or self-serve option. A company with limited inbound traffic has nothing for Warmly to identify, regardless of budget.

Which should you choose?
The cost gap between these two is enormous, roughly two orders of magnitude at entry, and that gap is not incidental, it reflects genuinely different jobs. Landbase's low cost is possible because natural language search against a database is inherently cheaper to run and scale than real-time visitor identification and autonomous multi-channel engagement. Warmly's five-figure entry price only makes sense if you actually have the traffic volume to justify it; a low-traffic company spending $10,000 a year on Warmly would be paying for an identification engine with almost nothing to identify.
Bottom line
Choose Landbase if your growth depends on proactively finding accounts that fit a specific profile, regardless of whether they have ever heard of you. Choose Warmly only if you already have meaningful qualified website traffic and the budget to match, since below that traffic threshold its core mechanic has nothing to work with. These two rarely compete for the same dollar: a company with strong inbound traffic and thin outbound capacity should look at Warmly first, while a company with little inbound traffic and a need to build pipeline from scratch should start with Landbase.
Frequently asked questions
Can Landbase identify anonymous visitors on my own website the way Warmly does?
No, Landbase has no website visitor identification or de-anonymization feature at all. It searches an external B2B database using natural language queries to find accounts matching your criteria; it has no visibility into who is currently browsing your own site, which is specifically Warmly's core function.
Is Warmly worth it if my company has very little website traffic?
Likely not. Warmly explicitly needs meaningful traffic volume to surface actionable leads regularly, since its entire mechanic depends on identifying real visitors on your site. A company with low or no inbound traffic would get more direct value from Landbase, which proactively searches for accounts rather than depending on existing site visits.
How much cheaper is Landbase than Warmly at entry?
Landbase's free tier costs $0 with no credit card required, and its top self-serve paid tier is $299/month. Warmly has no free tier at all, starting at $10,000/year for its most basic plan, with no monthly billing option, making Landbase dramatically cheaper to test and adopt at any comparable stage.
Does Landbase have anything like Warmly's Context Graph for tracking ongoing account engagement?
No, Landbase produces a qualified account list and enriched contact data at a point in time, but it does not maintain an ongoing, unified account view combining site visits, CRM activity, email, and chat logs the way Warmly's Context Graph does. That kind of continuous account intelligence is specific to Warmly's inbound-focused product.
Which tool is better for replacing an SDR agency?
Warmly is directly positioned for this use case, with customers reporting they replaced $20,000 to $40,000 per month in SDR agency spend using its AI-driven identification and engagement of website visitors. Landbase is a discovery and enrichment layer for a team's own outbound process, not a replacement for the SDR engagement function itself.
Could a company use both Landbase and Warmly together?
Yes, though it requires enough budget for both. Landbase could power proactive outbound account discovery for prospects with no existing awareness of your brand, while Warmly identifies and engages the separate population of visitors already arriving on your site through other channels, covering both directions of pipeline generation simultaneously.
