Landbase and 11x both promise to run outbound without a human SDR in the seat, but they start from opposite bets on how to get there. Landbase trains its own go-to-market model — GTM-2 Omni, launched January 2026 — on the outcomes of 50M+ campaigns, then lets you describe an audience in plain English and launch an email + LinkedIn sequence in minutes. 11x orchestrates general-purpose frontier LLMs behind a roster of named “digital workers” — Alice for outbound, Julian for the phone — and sells them as annual, sales-led deployments aimed at mid-market and enterprise RevOps.
The split that decides it: Landbase is a purpose-trained GTM model you can start on a free tier and run month-to-month; 11x is a multi-channel agent suite — including AI voice — behind a demo gate and a 12-month commitment.
Where Landbase wins
Purpose-trained model, not a general LLM wrapped in prompts. GTM-2 Omni runs separate planning, generation, and reward models trained by reinforcement learning on 50M+ real campaigns, with 30,000+ signals and 600M+ contacts feeding targeting. The buyer-relevant consequence is that list-building and qualification are tuned on what actually converted, not on a general model’s guess. 11x’s copy and research ride on frontier LLMs that were never trained on your funnel’s outcomes.
Start free, scale month-to-month. Landbase publishes a free tier — campaign planning and message generation, up to 10,000 contact exports per session — and a paid tier from ~$3,000/month with no annual lock. 11x has no self-serve and no monthly option; every deal is quoted annually.
Same-day launch from a natural-language brief. Describe “mid-market US healthcare companies hiring in compliance,” and GTM-2 qualifies and expands the list to 10,000+ prospects and drafts the sequence in minutes. 11x’s Alice needs ICP configuration, product training, and CRM wiring before the first send.
No separate data contract. Landbase’s 600M+ contact database is in the platform. 11x brings no owned data asset; its research draws on whatever provider you connect, so the real cost carries a ZoomInfo or Apollo line item on top.
Where 11x wins
Phone is a first-class channel. Julian — the voice agent 11x once called Mike — qualifies inbound and runs consented outbound calls in 30+ languages, books meetings, and writes back to the CRM after each call. Landbase runs email + LinkedIn only: no dialer, no voice. If AI phone touches are part of the motion, Landbase can’t do it and 11x can.
Deeper enterprise integration and posture. 11x ships native Salesforce and HubSpot sync plus Outreach, Salesloft, Slack, and LinkedIn, and targets complex CRM environments at 100+ rep companies. Landbase, which launched in 2024, is younger and lighter on enterprise-grade integration depth.
One vendor across inbound and outbound. Alice runs outbound; Julian covers inbound voice. For a team that wants a single contract to span both motions — not just outbound campaign automation — 11x has the wider product surface.
Pricing reality
Landbase: free planning tier, then $3,000/month ($36,000/year) for full autonomy with no annual commitment; enterprise deployments run higher — roughly $5,000–$10,000+/month — on custom quotes. You can start paid at month-to-month risk.
11x: no published pricing, demo-gated, quoted annually. Vendr marketplace data puts the median contract at about $40,125/year, with most between $38,250 and $65,550; G2 reports cluster at $5,000–$15,000/month once seats, channels, and Julian’s call volume are added, plus implementation fees that often clear $3,000.
Quantified, the entry gap is smaller than the commitment gap. Landbase’s ~$36K/year floor and 11x’s ~$40K/year median sit within about 10% of each other, but Landbase lets you leave after a month while 11x locks a year — and increasingly leads with multi-year terms. The larger cost 11x carries is the third-party data contract Landbase folds in.
Implementation
Landbase: minutes to days. A natural-language brief drives targeting, qualification, and message generation, and the free tier lets you pressure-test list quality before paying a cent.
11x: multi-week. Onboarding covers ICP setup, Alice’s training on your product and positioning, and CRM integration, with implementation fees on top. The payoff is broader coverage — voice plus inbound — once the agents are live.
Verdict
Pick Landbase when outbound is email + LinkedIn, you want to validate on a free tier and pay month-to-month, and you value targeting trained on campaign outcomes over a named voice agent. It is the lower-commitment entry to autonomous outbound.
Pick 11x when AI phone calls or inbound voice qualification are part of the plan, you are at a 100+ rep company with a complex Salesforce environment, and you want one vendor covering inbound and outbound — and you can fund a ~$40K+/year annual commit.
Pick neither when your outbound is under ~500 contacts/month or your ICP is still moving. At that stage Clay plus Apollo and a human SDR running tight sequences costs a fraction of either and keeps message control in-house while you iterate.
Default pick: Landbase. The free tier and month-to-month terms make it the lower-risk way to test whether an autonomous GTM model books meetings for your ICP, and its bundled data removes a second contract. Move to 11x when the motion genuinely needs AI voice or a single vendor spanning inbound and outbound — the capabilities that justify its annual commitment.
