Three ways to build B2B lead generation. All three make you build what already exists.
Three to four months before they produce, and six months in they have half of what already exists. If they leave, it leaves with them.
$15K to $36K year one, plus tools
It rents you people. What it learns about your ICP lives in someone’s head and walks out the day the contract ends.
you find out if it works on month three
You downloaded skills from GitHub and built a process that ran once and brought nothing, so you think the channel is dead. Or it brought some results, and now you have to close those deals and keep the system running at the same time. You never get a predictable, steady pipeline.
you drop the channel, or it eats your time
All three start from scratch. We already built it, operating, over three years.
01 · Immediate demand
Sources
End-to-end outbound via email + LinkedIn: infrastructure, data sources, AI personalization and pipeline management. The deliverable: qualified calls booked directly on your calendar. Live in 3–4 weeks.
02 · Authority & inbound
We run LinkedIn for your commercial profiles end-to-end: strategy, copywriting, design and publishing. You only review and approve. Every post warms up the prospects your outbound reaches.
03 · Operational efficiency
Custom AI agents and automations, one at a time, each in production before the next. CRM hygiene, pipeline signals, drafted follow-ups, automated reporting. Discovery and roadmap are free.
Because we did not build it for you: it was already built. Eight platforms we own, the data from three years of campaigns, and the nine-stage process that wires them together, for inbound and outbound motions. Every module exists because a client needed it and nothing did the job. None of them are on GitHub.
The modules are the same. What changes is who sets it up and who operates it.
tools included
For you if you have no team or no time to operate it.
What you get
In outbound: meetings booked with the person who makes the call.
you pay your own tools
For you if you have someone technical who can give it a few hours a week.
What the $400 pays for
you pay your own tools
For you if you want the system in-house but don’t want to build it.
It’s the answer to the question we get most from people who already hired agencies that overpromised: how do I buy this without a leap of faith. It isn’t a line on a website, it’s a clause.
01
We do the math together
On the first call we start from your business (deal size, close rate, sales cycle, how many meetings you need for the numbers to work) and from the plan you pick, which sets the volume that goes out each month. Those two set the goal for each month.
02
We sign it
The monthly goal and the term, usually three or six months, are written into the contract. Not in a proposal or an email.
03
If the goal is missed
Service
We keep operating without billing you until we reach the signed total. We don’t make it up next month while still invoicing: there is no new invoice until we get there.
In-house · GTM OS and Implementation
Your team runs the system, so what we put in is free consulting and support on your operation, until your team reaches the goal.
We count qualified meetings: ones that happened and that fit the ICP we defined together. We don’t promise closed deals, because those depend on your sales process. And there’s no number here because the goal is built from your numbers and the plan you pick, not another client’s.
The alternatives
Five ways to solve the same thing. This is what each one leaves out.

Book a Discovery CallWalkthroughs of the System, real campaigns and the tools we use, recorded on our own screen. In Spanish.
The system we use to generate B2B leads: eight platforms we built by operating (copywriting, WhatsApp, pipeline and dashboard, reply manager, domain health, analyzer, content and our own data base), the documented nine-stage process that wires them together, and the data accumulated over three years of campaigns. You can have it operated by us or run by your team.
An agency rents you people and starts from scratch with you: what it learns about your ICP lives in someone’s head and walks out the day the contract ends. We connect software we own and data from three years of campaigns, on top of the people. And if you want the system to live inside your company, we install it. An agency cannot hand you its agency.
You can, and you will be running in an afternoon. What you will not build in an afternoon is one system doing outbound and inbound at once, sending infrastructure that monitors and rotates itself, and everything measured by channel, segment and message. With loose skills every piece works but the whole thing breaks, and every week it takes more of the time you should be spending on selling.
Yes. The GTM OS runs on your own credentials from $400/mo: you pay for your tools and credits, and we never bill you for usage. If you would rather not set it up, Implementation means we install it, connect it to your CRM and train your team. It is in early access, so entry is through a call.
Someone comfortable in a terminal with Claude Code or a similar agent, a few hours a week, and accounts for the tools the process uses. The onboarding researches your company and builds your company types and buyer personas before you write a single message. If you do not have that person, the operated mode is the one for you.
Between 3 and 4 weeks from kickoff: we set up sending infrastructure, data sources and strategy, and the first qualified leads arrive around week 4. An in-house team takes 3 to 4 months to reach the same point.
It depends on the plan, the sending volume and the market. In LatAm the range runs from 7 to 25 depending on the plan, averaging 10 to 12. You can also set a cap: if your team cannot handle more than a certain number, we agree the limit before starting and stop there.
It’s in the contract. On the first call we start from your business (deal size, close rate, sales cycle, how many meetings you need for the numbers to work) and from the plan you pick, which sets the volume that goes out each month. Those two set the goal for each month. The monthly goal and the term, usually three or six months, are written into the contract. Not in a proposal or an email. Service: We keep operating without billing you until we reach the signed total. We don’t make it up next month while still invoicing: there is no new invoice until we get there. In-house · GTM OS and Implementation: Your team runs the system, so what we put in is free consulting and support on your operation, until your team reaches the goal. We count qualified meetings: ones that happened and that fit the ICP we defined together. We don’t promise closed deals, because those depend on your sales process. And there’s no number here because the goal is built from your numbers and the plan you pick, not another client’s.
Both, and they are not run the same way. Reaching the same number of meetings in the US takes five times the infrastructure and five times the sending volume, and LinkedIn content stops being optional, because there the prospect checks your profile before accepting. The US plans are sized for that.
To resolve variables, not to write. The analyst writes the structure of the message in blocks and the platform resolves each block lead by lead against your library and that lead’s data. If it cannot resolve one with confidence, a human-written fallback goes in. It never invents your copy, and nothing goes out without your approval.
A workshop call at the start to load your context, then review and approve the copy. Nothing else. In the in-house mode it is the other way around: you operate it and we keep the system updated.
