What we solve

Bring us the hard part.

Every engagement starts from a problem, not a technology. These are the three we see most — if yours is different, even better.

  1. The system that doesn't scale

    It worked at launch. Now every change is slower, every incident lasts longer, and the technical foundation works against the business plan.

    We profile it, redesign it, and rebuild it to hold production load — without stopping the business.

  2. The work that's still manual

    Hours of copying, sorting, checking, and reporting that your team spends on administrative work because that's how it has always been done.

    We build automation and AI agents that take the repetitive work — with guardrails and human control where it matters.

  3. The product stuck halfway

    An idea, a prototype, or a half-built application that never quite launches. Many projects get lost between the demonstration and real use.

    We cover the last mile with a solid technical foundation, rigorous engineering, and a launch you can maintain.

How we build

Technology that moves the business forward.

Behind Altitud are dependable tools for building products, connecting processes, and making sure an idea keeps working as it grows. You do not need to know them: we use them to make the whole thing work end to end.

Collaborative R&D

Research has to work, too.

ReasonLoom is an applied AI R&D project developed by an external team, with Elies participating as a collaborator. The work includes engines, evaluation systems, models, and tools tested against working software.

Delivery

Clarity first. Working software next.

The shape changes with the problem. The discipline does not.

  1. 01

    Diagnose

    We map the problem, constraints, current system, and the signal that would count as improvement.

  2. 02

    Decide

    You get a clear technical direction, scope, risks, and the smallest credible route to the outcome.

  3. 03

    Build

    We ship in visible increments, test the real boundaries, and keep decisions close to the code.

  4. 04

    Transfer

    The code, documentation, infrastructure knowledge, and next decisions stay with your team.

Elies Retamosa · Founder & software architect

Founder-led

The person shaping the solution is accountable for the build.

I'm Elies Retamosa, founder of Altitud Studio. Since 2016 I have worked across software development, architecture, technical leadership, product delivery, automation, and applied AI. You speak directly with the person making the technical decisions — no sales-to-delivery handoff.

Good fit

When the problem matters more than the buzzword.

Call Altitud when

  • The system is important and technically unclear
  • A senior decision-maker needs to stay close to delivery
  • You need a product, automation, or architecture that your team can own

Probably not the right fit

  • You only need a template website
  • You are buying anonymous developer hours
  • The project depends on unmeasurable AI claims

Contact

Tell us about your problem.

A system that misbehaves, a process that eats hours, a product that needs shipping — or just a technical question. We answer everything.
