Landbase vs Loops in 2026: B2B account discovery vs product email for signed-up users
Landbase finds and qualifies accounts you have never contacted, using natural language queries against a B2B database. Loops sends email to people who already use your product, and has no data or prospecting layer at all.
Landbase
Loops- Landbase finds and qualifies B2B accounts using natural language queries; Loops has no prospecting, search, or account discovery feature of any kind.
- Loops sends marketing, product lifecycle, and transactional email from one account; Landbase has no email sending capability, it only discovers and enriches contact data.
- Landbase offers a free tier with 1,000 one-time credits and no credit card required; Loops offers a free tier capped at 4,000 sends and 1,000 subscribers per month.
- Loops charges no per-seat fee, only by subscribed contact count; Landbase charges per verified email or phone number retrieved, with account search and AI qualification free at every tier.
- Landbase was named a Gartner Cool Vendor and raised a $30M Series A; Loops is Y Combinator-backed and used by Framer, Linear, and Perplexity.
- Landbase's natural language search covers tech stack detection and department headcount, filters neither Apollo nor Loops offer natively; Loops' strength is event-driven automation triggered by product usage, not account filtering.
Landbase and Loops rarely compete for the same budget because they operate on opposite sides of the customer relationship. Landbase is a GTM data platform: describe your ideal account in plain English and its GTM-2 Omni model returns qualified companies and enriched contacts, charging credits only for verified results. Loops is a unified email platform for marketing, product lifecycle, and transactional messages sent to people already inside your product, priced by subscribed contact count with no per-seat fee. Landbase has no email sending capability whatsoever; Loops has no prospecting or account discovery feature whatsoever. The overlap is really just the "Marketing Automation" category label, not the actual job either tool does.
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 solves a problem that shows up before there is anyone to email: figuring out which companies to target in the first place. Instead of clicking through filter menus, a rep types something like "US SaaS companies with $10M to $50M ARR using Salesforce and HubSpot with 50+ employees in engineering" and the GTM-2 Omni model, trained on more than 50 million GTM campaigns, returns matches in seconds.
Every account that comes back is scored for ICP fit at zero credit cost, so a rep can filter a large result set down before spending a cent on contact enrichment. Enrichment itself only charges when Landbase delivers a verified email or phone number, which removes the waste of paying for failed lookups that plagues per-attempt pricing models.
What Landbase will not do is send that contact anything. There is no sequencing, no email builder, and no campaign engine, only a CLI and API for feeding the enriched data into whatever tool actually does the outreach. It is explicitly a data layer, not a full-funnel platform.

Loops
Unified email platform for SaaS teams covering marketing, product, and transactional email from a single simple interface.
Loops assumes the hard part of finding an audience is already done, because its audience is your own product's users. Marketing campaigns, onboarding sequences, and transactional sends like password resets all run through the same contacts, events, and event properties model, which means one account and one domain cover email types that most companies split across two or three vendors.
Event-driven automation is the mechanism: a signup, a trial start, or a feature activation triggers a workflow, and the visual builder makes editing that flow straightforward without engineering help for every change. A clean REST API with SDKs for Node, Next.js, Ruby, PHP, and NuxtJS, plus an MCP server, mean developer teams can wire product events into email quickly.
None of this touches account discovery. Loops has no way to find a company you have never heard of or enrich a contact you do not already have in your product database; it is exclusively for communicating with people who already opted in by using your app.

Which should you choose?
LandbaseLoopsLandbaseLoopsLandbaseLoopsThere is no real tension to resolve here since the two tools do not compete for the same job. Landbase answers "who should we be talking to," and its natural language search genuinely handles account queries that would require custom Clay code or manual Apollo filtering elsewhere. Loops answers "what do we say to the people already using our product," and its unified transactional-plus-lifecycle model is a legitimate simplification for SaaS teams juggling separate vendors. Pairing them, Landbase feeding a list into a separate sequencer while Loops handles post-signup email, is a more coherent stack than trying to force either one to do the other's job.
Bottom line
Choose Landbase if your problem is finding and qualifying accounts you do not yet have contact data for. Choose Loops if your problem is communicating with users who already exist in your product. Neither is a substitute for the other, and a growth-stage SaaS company will likely end up running both alongside a separate outbound sequencer that consumes Landbase's enriched contacts.
Frequently asked questions
Can Loops be used for cold outbound prospecting instead of Landbase?
No, Loops has no prospecting, account search, or contact enrichment feature and is designed exclusively for emailing people who have already opted in by using your product. Cold outbound prospecting is Landbase's job, which finds and qualifies new accounts through natural language queries against its B2B database.
Does Landbase send emails to the contacts it finds?
No, Landbase focuses entirely on account discovery, AI qualification, and contact enrichment, and explicitly does not include sequencing or outreach tools. You would need to export enriched contacts into a separate sequencer or, for product users, a lifecycle tool like Loops, though Loops itself is not built for cold contacts either.
Is Landbase or Loops better for a SaaS startup just getting started?
It depends on which side of the funnel needs attention first. A SaaS startup validating its target market before it has customers should start with Landbase's free 1,000-credit tier. A SaaS startup that already has signed-up users needing onboarding and transactional email should start with Loops' free plan, which covers up to 1,000 subscribers.
How does Landbase pricing compare to Loops pricing at the free tier?
Landbase's free tier gives 1,000 one-time credits worth roughly $49, usable for account search, AI qualification, and a limited number of verified contact lookups, with no credit card required. Loops' free tier is ongoing rather than one-time, capped at 1,000 subscribed contacts and 4,000 email sends per month, also with all features included.
Does either tool integrate with a CRM or sequencing platform?
Landbase offers a CLI and API for feeding discovered accounts into other tools, including CRMs and sequencers, though native integrations are not prominently documented. Loops connects natively to Supabase, Clerk, Stripe, PostHog, Auth0, and Segment, plus Zapier and Make, which covers most of a typical SaaS product stack rather than sales tooling.
What is GTM-2 Omni and how is it different from what Loops uses under the hood?
GTM-2 Omni is Landbase's proprietary AI model, trained on more than 50 million GTM campaigns, powering account discovery, qualification scoring, and lookalike matching. Loops does not run a comparable proprietary AI model for its core function; its differentiator is the unified contacts-events-properties data model and a clean developer API, not an AI layer for finding new customers.
