We build AI assistants, automations and custom tools that answer your enquiries, handle the admin and work inside the software you already use. For businesses that want the results without hiring an AI team.
You work directly with the engineer who builds it. A fixed-price audit first, then a costed plan you keep either way. Based in Marbella, working remotely across Spain, the UK and Europe.
Most businesses have watched the demos and tried a tool or two. What they do not have is something running every day that saves real hours. That is the gap we close.
The trial looked great, then fell over on logins, permissions, errors and the real volume of data.
People who have put AI systems into daily use are rare, cost a lot, and are not on the market for long.
An assistant with no access to your CRM, inbox or documents can answer questions. It cannot do work.
AI tools drift as the models change and costs creep up. Without someone watching, quality quietly drops.
The real work is the unglamorous part: connecting your tools, testing on real data, controlling cost and handling what goes wrong. That is what gets a system live and keeps it there.
Working systems, scoped and shipped. Not workshops, not strategy decks.
When one chatbot answering questions is not enough.
A team of specialised assistants, each with one clear job, sharing one memory, with a control layer that decides what runs, in what order, and what happens when a step fails.
When the AI has to work inside your CRM, accounting, booking or ticketing system.
We connect AI models to the systems you already run, including the logins, permissions, rate limits and data mapping that trial projects skip.
For the team making the same judgement call two hundred times a week.
Purpose-built screens where the AI does the first pass and a person approves, corrects or overrides. Built for the specific job, not a general chat box.
When the answer exists somewhere in twenty years of files.
We ingest, organise and index your documents so staff and customers get accurate answers, with your access rules respected and accuracy measured rather than assumed.
For systems already live that nobody in the business is watching.
We build it and we run it. Monitoring, testing against real traffic, cost tuning, and updates as your data and the underlying AI models change.
The AI system we built and run ourselves. It operates ThreeStepTech every day: inbox, calendar, payments, CRM and follow-up. Everything described above exists here first.
Each assistant owns one part of the business and has its own tools and instructions. All five read and write the same memory, so context carries between them and across sessions instead of resetting every conversation.
Every action the assistants can take, from sending an email to updating a deal, reaches them as a typed tool over MCP, the open standard for AI tool access. New actions can be added without rewriting the assistants, and every call is logged.
Five kinds of search, by meaning, by keyword, by recent importance, by what the other assistants have done, and by the current thread, merged into one briefing per request. When two facts disagree, it flags the contradiction instead of silently picking one.
Gmail, Google Calendar, Stripe, GoHighLevel and Telegram. Real inbox, real calendar, real payments. There is no test environment where a failure could go unnoticed.
A Next.js dashboard on Supabase, a Node service layer holding the assistant runtime and integrations, and a Python bridge for voice. The runtime drives Claude through the Agent SDK. It is a working system, not a chat window bolted onto an API call.
In continuous use for months on live accounts, not a demo. It has already survived model upgrades, API changes and the edge cases nobody plans for at the start.
AIOS itself is not for sale. It is the proof: this has been built end to end and kept running under real load. We build systems like it for clients as their own private AI operating system, trained on their documents, processes and data.
One fixed-price starting point. Everything after it is scoped from what the audit finds, not from a guess.
Fixed price, fixed scope, fixed timeline. You keep the plan either way.
We map how work moves through your business, show what can be automated today, and hand you a costed build plan. It is yours whether or not you continue.
For teams that want an engineer working alongside them, or technical direction on their own AI plans, rather than a fixed deliverable. Booked in blocks of three days or more.
Scoped from the audit. The range depends on how many systems we connect and how clean your data is.
Building and launching the system the audit specified. Typically four to ten weeks, delivered in stages you can review, not one handover at the end.
AI systems drift as the models and your data change. These plans are for teams that would rather not hire someone to watch for that.
Monitoring, testing and improvement of a system that is already live.
Reserved build time each month for companies running several systems or expanding AI into new parts of the business.
The audit is the only fixed price on this page, and that is deliberate. Build and monthly figures are ranges because the cost depends on how many systems we touch and how clean the data is, and the audit establishes both. Day-rate work is available without an audit where you already know what needs building. All prices are in euros.
Three practical differences, not slogans.
You brief the engineer and the engineer writes the code. Nothing is relayed through an account manager or passed to a team you never meet.
A demo is not a milestone. We measure the work by what is running on real traffic with monitoring attached, not by what was shown on a call.
The code and infrastructure live in your accounts. The audit plan is yours whether you continue with us or take it elsewhere. No black box you cannot leave.
Three stages. The first has a fixed price, and the second is scoped from what it finds.
Two weeks mapping how work moves through your business and which systems need connecting. You get a costed build plan naming what to automate, what not to, and in what order.
Built in stages you can review as we go. Testing and monitoring ship with the system rather than being added after something breaks.
Handover to your team, or we keep running it for you if you would rather not hire someone to watch for model changes, cost creep and new edge cases.
Audit: two weeks. Build: four to ten weeks depending on how many systems are involved. Remote across Spain, the UK and Europe, with US time zones covered by agreed overlap hours.
Two weeks, fixed scope, €3,500. We map how work currently moves through your business, work out what can genuinely be automated with today's AI, and give you a costed build plan with the order to do it in and the risks to watch. You own the plan whether or not you continue with the build.
You work directly with the engineer who builds it. There is no account manager in between and no outsourced delivery team. That is a feature and a constraint: capacity is limited, so we take on a small number of builds at a time.
Yes. We are based in Marbella and work remotely with clients across Spain, the UK, Europe and the US, with overlap hours agreed at the start. Most build work happens asynchronously, with scheduled review calls.
Demos fail on the parts nobody plans for: logins and permissions, rate limits, error handling, testing, cost control, and connecting to systems that were never designed for AI. The audit prices those in before anyone writes code, and the build treats them as the main work rather than as edge cases.
Builds run €10,000 to €25,000 depending on scope, typically four to ten weeks. Day-rate work is €600 to €850 per day where you want an engineer alongside your team rather than a fixed deliverable.
Managed automation ops runs €2,500 to €5,000 per month: monitoring, testing against real traffic, model and cost tuning, and ongoing improvement. AI systems drift as the models and your data change. Handing over the code and walking away is how they quietly stop working.
Every build is its own separate deployment with its own database. Nothing is shared between clients. The system runs in your cloud account, or in one we set up and hand over to you. Your documents and internal data are never used to train external AI models, and data boundaries are agreed in writing before any build starts.
€3,500, two weeks, fixed scope. A costed build plan you own, whatever you decide to do next.
