Six ways to build.

Introduction transcript. Client: I’ve got all these tools. Can they work together? Qubi: Ooh, a little tangle. I can help with that. AI agents. Automation. Custom software. We connect the pieces around the way you work. Client: So, I get the final say? Qubi: Of course. Your team. Your rules. Client: Now that’s my kind of clever. Qubi: And code you own. Ready when you are.

At a glance

The short version.

01 Who we are
QQuantum.ai is an AI systems engineering studio based in Barcelona, working remotely with clients across Europe and beyond.
02 What we sell
Custom-built AI systems and the engineering around them. We are not a software reseller, and we take no commission from any model provider or cloud.
03 Six service lines
AI architectures, autonomous employees, intelligent automation, algorithmic marketing, creative design and rapid prototyping.
04 How it starts
A scoped pilot, typically two to six weeks, that answers one question about your workload before anyone commits to a platform.
05 What you keep
The source code, in your repositories, running on infrastructure you control if you want it there. No licence to renew to keep the system running.
06 What we do not claim
We hold no security certifications or vendor accreditations, and we publish no client metrics we have not measured. Where a page shows numbers, it says whether they are design targets or measurements.
Which one do you need?

Start from what is stuck.

Start from the bottleneck rather than the technology. Pick the one that sounds like your week: the answer is the service line we would start from, and the pages to read first.

Which sounds most like this week?

Most engagements end up crossing two of these. The line you start from decides the first pilot, not the shape of everything after it.

Your answer · our first move

Pick the one that sounds like your week, and we will tell you where we would start.

Each answer points at one of the six service lines and the pages to read first. If none of them fits, that is worth a call too.

Start with · ARC

AI Architectures

The knowledge exists but nobody can get an answer out of it — it is spread across a document store, a warehouse and a system nobody wants to touch. Start with architectures: retrieval, orchestration and the pipelines that reach the data where it already lives.

Read first · 4 of 5 pages
Start with · AGT

Autonomous Employees

The work is well understood and there is simply more of it than the team can carry — support tickets, account research, recurring analysis. Start with agents that hold the role end to end and escalate what they cannot evidence.

Read first · 4 of 4 pages
Start with · AUT

Intelligent Automation

The steps are known but they span systems that were never designed to talk to each other, and the rules have too many exceptions to encode. Start with automation that reasons about the exception rather than branching on it.

Read first · 4 of 4 pages
Start with · MKT

Algorithmic Marketing

The offer works and distribution does not scale with headcount. Start with marketing systems: programmatic page structures built on real data, outreach that reads the news cycle, forecasting from your own history.

Read first · 4 of 4 pages
Start with · CRE

Creative Design

The model is good enough and people still will not use it, because nobody can tell what it is doing or when to trust it. Start with design: product interfaces built around an AI system, and the identity around them.

Read first · 4 of 6 pages
Start with · PRO

Rapid Prototyping

There is a plausible idea and no evidence either way, and the argument has been going on longer than the build would take. Start with a prototype scoped to answer one question, then decide.

What the six have in common

Six shapes. One practice underneath.

The service lines are six ways into the same practice. Underneath all of them is one job: getting a language model to do useful work on your data, repeatedly, in a way somebody can check. The differences between them are differences of shape — an agent that holds a role, a pipeline that runs unattended, an interface a customer touches — rather than differences of underlying craft.

That is why the split is by what you are buying rather than by technology. A retrieval system, a support agent and a lead-qualification workflow may share most of their code and all of their evaluation harness; they are separate pages because they are separate decisions, with different budgets, different owners and different ways of going wrong.

Four things are constant across every engagement, and they are the parts most likely to be missing when a project arrives here from somewhere else. Retrieval and citation, so an answer can be traced to the passage it came from. Evaluation that keeps running after launch, built from real examples of your task, because quality decays quietly. Observability, so a bad week is visible before a customer reports it. And an exit: the code is yours, the model is a swappable component, and nothing in the design assumes we are still here in a year.

What we do not do is sell a platform. There is no QQuantum runtime you have to keep paying for, and no architecture we prefer because we resell part of it. Model providers deprecate versions and change prices; a system that treats the model as a component survives that, and one built around a single vendor's quirks does not.

The six lines
In every one of the six · 01/04

Retrieval with citation, so an output can be attributed to a source and a model version. This reduces and grounds model error; it does not eliminate it, and any page claiming otherwise is selling something.

Without it An answer nobody can trace to a source, so nobody can tell a right one from a confident one.

In every one of the six · 02/04

A regression gate built from real examples of your task, running after launch as well as before it. Delivered with the system, in your repository.

Without it Quality decays quietly, and nobody can say whether the last change made things better or worse.

In every one of the six · 03/04

Traces, costs and failure rates visible to your team, so a degradation is something you notice rather than something a customer reports.

Without it A bad week is discovered by a customer rather than by your team.

In every one of the six · 04/04

Source code in your repositories, deployment on infrastructure you can control, and a model layer designed for substitution when a provider deprecates or reprices a version.

Without it The system lasts exactly as long as one vendor relationship does, and a deprecated model version becomes your emergency.

How an engagement runs

From one call to production — or a clear no.

Four stops, each ending in something you can check. Pick one, or let it play through.

01 · Call one

The constraints, before the solution

A technical call about the workload: where the data is allowed to live, what the task actually demands, what latency the interface can absorb, and what a request may cost at your volume. Capability is rarely the binding constraint, so it is rarely where we start.

02 · Weeks 1–2

Scope and a written proposal

A fixed scope for a pilot that answers one question, with the acceptance criteria written down before the work starts. If a cheaper approach would settle the same question, the proposal says so.

Fixed price for the pilot
Named acceptance criteria
Explicit assumptions, so a wrong one is visible early
03 · Weeks 2–6

A pilot you can put in front of real work

A working system against your own data, with an evaluation harness built from real examples of the task. The harness is part of the deliverable, not a phase we skipped: without it, nobody can say whether the next change made things better.

04 · After the pilot

Production, or a clear no

Hardening, observability, access control and handover — or a documented reason not to continue. A pilot that answers no has done its job, and it costs a fraction of finding out later.

Questions

What people ask before choosing a service.

What services does QQuantum.ai offer?

Six lines. AI architectures (LLM orchestration, retrieval systems, legacy modernisation, secure data pipelines). Autonomous employees (agents for sales, support, analysis and internal operations). Intelligent automation (lead qualification, cross-platform workflows, financial automation, HR onboarding). Algorithmic marketing (programmatic SEO, journalist outreach, link building, predictive analytics). Creative design (web design, application UI/UX, brand identity, agent style training). And rapid prototyping (working software built to answer one question). Every one of them is a custom build, not a licence to a product we own.

Which service should I start with?

Start from the bottleneck rather than the technology. If the knowledge exists but nobody can retrieve an answer, start with architectures. If a role has more work than the people in it, start with autonomous employees. If a process spans systems that do not talk to each other, start with intelligent automation. If distribution is what does not scale, start with algorithmic marketing. If people will not use what already works, start with design. If there is no evidence either way, start with a prototype.

Do you work on a fixed price?

Pilots are fixed-price against written acceptance criteria, because that is the part where a client is buying without evidence and should not also be carrying the estimate risk. Longer production work is usually scoped in phases. Indicative ranges are on the pricing page; a real number needs a call about the workload.

How long before we see something working?

Two to six weeks to a pilot running against your own data, for most scopes. That is a design target rather than a guarantee: an engagement that depends on access to a system nobody has documented is slower, and we will say so during scoping rather than after.

Do we own what you build?

Yes. Source code goes into your repositories from the beginning, and the system is designed to run on infrastructure you control if that is what you want. There is no runtime of ours you have to keep paying for, and no key we can revoke.

Which models and vendors do you use?

Whichever the workload argues for, benchmarked against your task rather than a public leaderboard. We work with frontier APIs (Anthropic, OpenAI, Google) and open-weight models you can self-host (Llama, Mistral, Qwen, DeepSeek). We resell none of them and earn no commission from any of them, which is the only reason a recommendation from us is worth anything.

Can the system run on our own infrastructure?

Yes, including fully on-premise for workloads that cannot leave your building. The hosting and infrastructure section sets out the four options — your building, a private rack, your own cloud account, or a public API — and what each one costs and protects.

Do you hold security certifications?

No. We hold no certifications or attestations, and we do not describe our work as aligned to one, because that reads as a credential at a glance. What we do instead is build so that your auditors can evidence the controls they test: data residency you choose, access control you own, and logs you keep.

Do you work with startups as well as enterprises?

Both, and the shape of the work differs. Enterprise engagements are built around security review, procurement and legacy systems; startup engagements are scoped around runway and the next investor milestone. There is a section for each.

Where are you based, and does it matter?

Barcelona, working remotely across Europe. It matters for two reasons: European working hours for a European client, and GDPR as the default assumption rather than an afterthought, including keeping data inside the EU where a workload requires it.
