Websites, custom software, SaaS and more.

MDC21 is an independent software development studio for companies in Spain and the European Union. We design, build and maintain production systems for teams that need them done right — marketing websites, e-commerce, custom Laravel platforms and SaaS products.

03 / Services

Five things we do.

Each row expands. Clear scope and a single contact to start. We reply within one business day with a concrete proposal.

Service · 05
Cybersecurity

Technical audits, infrastructure hardening and incident response planning. We identify OWASP risks, configure defences and leave an actionable report. Before the incident, not after.

E-commerce, SaaS and companies with sensitive data or an upcoming external audit.

04 / How we work

How we work.

Every project is different, but the path looks the same. Four phases, one contact, regular check-ins.

01 · You leave with a written scope
Starting point

A short paid work session where we listen, write the scope with you, model the data and estimate effort per phase. You walk away knowing what we would build and what it would cost — with a clear go / no-go.

02 · You see a clickable prototype
Design

From wireframe to a navigable prototype reviewed every week. We design in the browser so what you click is what gets built.

03 · You see progress regularly
Build

Short sprints with regular check-ins and a staging URL from the first week. You see what we are building as we build it — no silent months, no surprises at handoff.

04 · You own everything
Care

Hand-off or a maintenance retainer — your choice. Either way the code, the infrastructure and the docs are yours from day one.

05 / How we work with you

You see every euro

We estimate by phase before starting and you approve each one. No hidden hours, no expanding scope, no surprises in the invoice.

You own everything

Code, infrastructure, documentation — all yours from day one. No vendor lock-in. If we walk away tomorrow, another team can pick it up on Monday.

You see progress regularly

Short sprints with regular check-ins and a staging URL you can show your team from day one. No silent months, no "trust us, it is almost done".
