The terms, written the same way the rest of the site is
Two things live on this page. The terms you are using this website under, and the shape of the terms an engagement runs under.
The second one is a summary, not the contract. The contract is the written proposal you sign, which carries the scope, the fee, the timeline and the test. If this page and that proposal ever disagree, the proposal wins, because it was written for your job and this was written for everybody.

Using this website
You can read it, quote it with attribution, and link to it. The legal notice carries who runs it and the details Spanish law requires.
Nothing here is an offer, a quote or a price. There is no figure published anywhere on this site, no payment is taken here, and nothing you can click commits you to anything.
Nothing here is professional advice. The articles describe methods and cite public research. They are written to be useful on their own and they are not a substitute for a lawyer, an accountant, or anyone who owes you a duty of care.
We try to keep it accurate and we will sometimes be wrong. If you find something wrong, tell us at hi [at] aeia.dev and we will fix it or say why we disagree.
What is deliberately not on this site
These are positions, not omissions, and they are the same in the contract as they are in the marketing.
No published prices. Every engagement is scoped before it is priced, so the number you get is a real number for your business rather than a band you have to guess your way into.
No published guarantee. There is no money-back promise written anywhere on this site, and you should not read one into anything here. What there is instead is a pass or fail test, agreed and signed before each paid step begins, which is a different and more useful thing.
No promise about your results. We do not commit to a figure for your revenue, your traffic, your leads, your rankings or your conversion. There is no baseline in your market to promise against, and inventing one is a documented way for an agency to lose a client in month four.
No testimonials or client results. Nothing on this site claims an outcome we cannot show you the source of. The reasoning is on the Work page.
How an engagement starts
Nothing starts until you sign
- An email. You write to hi [at] aeia.dev and the people who would do the work answer you. No fee. If it is not a fit we say so in the reply.
- A written proposal. Scope, what is delivered, what we need from you, the timeline, the fee, and the pass or fail test where the step has one.
- Your signature. Work begins after that and not before. An enthusiastic email thread is not an instruction to start, which protects you as much as us.
- Then the method, which is published in full on the Studio page and is part of what you are buying.
If the scope changes once we are underway, we requote before we build, not after.
What the proof month and the pilot mean in writing
The rest of the site describes both. Here they are as commitments rather than as description, so there is no gap between what was read and what was signed.
The 30 Day Proof Month, on either growth system. Defined output, and a pass or fail test signed before the month starts. At the end you either start the term or stop with nothing further owed, and you keep what was made: the brand voice profile, or the customer profile and the prospect file. There is no notice to serve and no term to buy out, because the term has not started. The proof month itself is paid work and its fee is not refunded, because the output exists and it is yours either way.
The operations pilot. Two to four weeks on one workflow, with the same kind of test written and signed before any build money is spent. The pilot fee is separate and is not credited against a later build, because the pilot delivers a real answer in both directions and an answer of "do not build this" costs us the same to produce as an answer of "build it".
The audit credit. If an AI Audit leads to a Custom AI Build, or to the setup for either growth system, the audit fee comes off that work in full, on any statement of work signed within 90 days of the day your walkthrough is delivered. It is not credited against the operations pilot.
Adoption is inside the scope, not sold as an extra. Training in your team's language, thirty days of adoption support after go live, and a written handover delivered by default at go live rather than on request.
What we need from you
The same list as the Studio page, because it belongs in both places.
- One named decision maker who can say yes without assembling a committee.
- Access to the people who do the work being changed.
- The material we are working from: existing content and how you talk, or logins and a walkthrough of the tools.
- A named reviewer who reads what we send, in the language it ships in.
- A straight account of what has already been tried.
If access slips, the timeline slips. We put that in the weekly note rather than absorbing it in silence and arriving late with an explanation.
Who owns what
What we make for you is yours, once it is paid for. The content, the configurations, the documentation, the brand voice profile, the customer profile, the prospect file. Yours to keep, to hand to somebody else, and to use without us.
What we brought with us stays ours. Our methods, our internal tooling, our templates and anything that existed before your project. You get the benefit of it inside your engagement, and you are not buying the studio.
The written handover is delivered by default at go live. Not on request, not on exit, and not as a bargaining position. You should not be dependent on us to understand your own system, and if we ever are the reason you cannot leave, we have built the wrong thing.
Confidentiality, both directions
What you tell us about your business stays with the people who work here. We do not repeat it to other clients, we do not use your name as a reference without asking, and we do not put a client's material into anything shared.
The same runs the other way: our proposals, our pricing for your job and our working documents are for you, not for forwarding to a competitor of ours to quote against.
If you need a separate confidentiality agreement, ask before we scope the work rather than after. We sign them.
Publishing the work
We publish one case study in full, and we intend the first client engagement that finishes to be the second. That is a commitment made in public on the Work page, including the part about publishing what did not work, so it has to be arranged at signature rather than asked for afterwards.
So our contracts include a publication clause, and it is written to be readable. In outline:
- We may publish a written case study about the work.
- You choose whether you are named or described anonymously, and you can change that choice later.
- We may describe the process, the timeline and what did not work, because a case study that only carries the good parts is advertising.
- You get an approval window on the draft, in which you can correct anything factual.
- Genuinely confidential commercial figures are carved out. Your revenue, your margins, your prices, your customer lists. Those never appear, and you do not have to justify asking for them to come out.
- You are not paid for it and you get no discount for it, so nothing here buys a favourable write-up.
The full clause is in the contract, in both languages, and you can read it before you sign anything.
Invoices
Fees are fixed and agreed in writing before the work they cover begins. We do not bill open ended time and materials.
Stopping
Every paid step has an exit and each one is described on the Studio page rather than discovered later.
A growth term can be stopped. A care plan can be stopped. What you keep is everything written down and handed over, which is the point of handing it over by default.
If you are buying as a person rather than as a business
Almost everything we do is business to business. If you are buying as a consumer, Spanish and European consumer law gives you rights that these terms cannot reduce, and nothing here takes them away.
Which law applies
Spanish law governs these terms and any engagement made under them.
Changes to this page
When we change it, the date changes. A change here does not change a proposal you have already signed. That document stands as signed.
