Bring what you are publishing now, or the list you are working from. We take it from there.
If you would rather write first, the contact page has the calendar at the top and a short form under it.
The systems that bring customers in.
Two engines. One publishes in your voice every month, in Spanish and English, with a named writer signing off every piece. The other finds the businesses worth talking to and verifies them before you spend an hour on any of them.
The proof is already running.
GROWTH SYSTEMS 2 ENGINES EN / ES
Who this is for
You are the owner, or you are the one person responsible for marketing. Publishing stops the week you get busy, and then it stays stopped. New business turns up when a referral happens to land, so you cannot plan around it. You have tried an agency retainer that cost more than the output was worth, or a tool whose output you would not put your name on.
Growth systems work on the supply side of that. Content that ships whether or not you had time this month, and prospects that arrive researched instead of bought.

Two engines
-
Proofloop, the content engine
A brand voice profile built from your existing material and from how you speak, not from a questionnaire. A read on what is working for your closest competitors. Then a monthly pack: posts, scripts, shot lists and briefs, ready to publish, in one language or both. A named human writer reviews and signs off every piece before it goes out, and you see who. Each month closes with a performance read and what to change next month.
Setup takes three to four weeks. After that it is monthly.
-
Firstline, the lead engine
We define your ideal customer profile with you, then find the businesses that match it and remove the duplicates. Each record gets enriched from the company's own website, its email addresses verified and its phone numbers put into one format. Everything is scored, so a sales conversation starts with the useful ones at the top. The file lands in your CRM, or in a simple one we stand up for you and hand over.
Every record carries a documented source, and the lawful basis for using it is written down before it is used. B2B prospecting in Spain sits under GDPR and LSSI-CE, and most of this market does not mention that at all.
Firstline earns its own page the way everything here does, by running first. Discovery, enrichment and verification have run at scale on our own pipeline, and the counts are below. We publish what a system has done rather than what it was designed to do, so the page goes up when the rest of it has run here too.

What these two engines have processed
Proofloop, running on Hairy Housemates, a brand of ours
12,462 posts indexed, across all 38 brands
- 223 of those, posts from our own shop
- 31,070 post performance metrics captured
- 10,487 indexed evidence passages
- 38 brands tracked, ours among them
- 122 social accounts monitored
- 186 website snapshots across the set
- 29 creator briefs generated
- 1,344 media assets processed
Records by kind1 to 100K
Indexing started in July 2026, so these are the size of an evidence base rather than a monthly rate, and the big number covers the whole tracked set rather than the one shop the engine runs for. The case study breaks that down further, including how much of the index arrived in a single import.
Firstline, discovery, enrichment and verification
45,882 prospects discovered and deduplicated
- 45,540 prospects scored
- 7,586 records enriched from source websites
- 1,703 email addresses verified
- 3,611 phone numbers normalised
- 67 business segments covered
- 6,619 distinct locations
- 5,309 discovery queries run
Records by kind1 to 100K
Both engines work in English and Spanish, and both languages get the same treatment.
Every figure above counts what these systems processed inside our own businesses. Not one of them is a claim about anyone's revenue, traffic, leads or rankings. We build it, we run it, then we sell it, and the only numbers we publish are the ones that running it produced.
The content engine has the fuller story: the Hairy Housemates case study shows what a month of it looks like end to end.
OPERATIONAL SCALE OUR OWN SYSTEMS, NOT CLIENT RESULTS FIGURES VERIFIED 2026-08-10
Both engines open the same way
Thirty days. A defined output, and a pass or fail test that we agree and sign before day one, so neither of us gets to decide afterwards what counted as success.
At the end you either start the term or you stop there, with nothing further owed. Either way you keep what was built. With Proofloop that is the brand voice profile, as a document you can hand to any writer. With Firstline it is the ideal customer profile and the prospect file.
The three month minimum applies to the term once you start it. It does not apply to the first thirty days.
Straight answers
Will it read like AI? A named writer reviews and signs off every piece before it ships, and you see who signed it. The studio has a copywriter and a creative director doing that review, so it is a gate in the process and not a line in a proposal.
When do I see anything? The competitor read lands in week two, before the first piece publishes. You are not waiting a month to find out whether this was a good idea.
What if I stop after the proof month? You keep the brand voice profile, or the ideal customer profile and the prospect file. They are standalone documents. Take them to another supplier if you want to.
Is prospecting like this legal in Spain? It sits under GDPR and LSSI-CE. We write down the data source and the lawful basis for every one of them before anything is used, and that document is yours. Most competitors here do not raise the subject.
Where does the prospect file land? In your CRM. If you do not run one, we stand up a simple one and hand it over. It is yours, and it works without us.
Do you publish prices? No. We scope every engagement before we price it, so the number you get is a real number for your business rather than a band you have to guess your way into.
What goes in writing
The output. How much ships, in which languages, reviewed by which person, on which dates, and the test we both signed at the start. Judge us on that.
We will not put a figure on your revenue. Nobody selling you a growth system knows your baseline, your close rate or how your market behaves in November, and a figure invented before any of that is known is a sales device.
If your problem is the other one
If enough of the right people already arrive and the trouble is the work they generate, that is the other family. Operations systems take repetitive process off the desk.
If the gap sits with your team, AI Foundations for Teams is half a day on their real workflows, with a playbook and a data handling policy they keep.
If you want a written picture before committing to any of it, the AI Visibility Audit covers both families and its fee comes off either growth setup fee if you sign within 90 days of the walkthrough.
And if what you want first is the method, it is published in full, phase by phase, with the risks named.
