Services
Three tracks, taken separately or in sequence. BUILD ships the software, GROW makes it findable by people and by assistants, CARE keeps it secure, current and improving. Most clients start with one and add the others once the first is running.

BUILD is Polargate's delivery line for custom software: websites, products, internal portals, mobile apps, AI features and integrations. Scope and price are settled in a paid Discovery Sprint, the build is fixed price, and the first iteration reaches production in four to eight weeks.

Work
Work that shipped: hotel and resort websites, an operating system for a hotel refurbishment contractor, a homeware shop rebuilt around a single photograph, an employee portal for a travel group. The numbers in each case are technical and verified. We name a client only where the work is already public; anything under an agreement is described without the name.
Elite Smart BuildA custom operating system for Elite Smart Build
Elite Smart Build, a Spanish hotel refurbishment contractor working in more than twenty countries, ran every site on spreadsheets and email. Polargate replaced that with eleven modules on Supabase and React: daily Gantt, role-masked margins, per-department alerts and material reception with automatic incidents.

Concert Music FestivalFrom a frozen line-up to an app that updates itself
A Spanish summer music festival had its line-up compiled into the app binary and its backend locked inside a no-code platform. Polargate rebuilt the foundation in four days, ten days before the season started.

Hotel MarienA resort website that Google, social scrapers and AI assistants can actually read

Industries
The work concentrates where a digital surface carries real revenue: hotels and resorts, corporate groups, events and nightlife, leisure and golf, industrial and B2B manufacturers, retail and e-commerce. The pattern repeats across all of them: several languages, an operational system behind the marketing site, and a team too small to staff it internally.
Portals that pass the security review.Corporate groups
Employee portals, internal CMS and workforce tools for corporate groups, built on Microsoft Entra ID single sign-on and delivered with the security evidence your review will ask for.

Why companies work with us
Senior-led, with no junior layer
The people who scope your project write the code. Polargate is run by its founder, Pedro Ciordia, with his brother Andrés Ciordia on the AI side and specialists brought in by name when a project needs them, so nobody learns on your budget and nothing is lost in a handover. Your contact is one of the two, has read your repository and can answer without checking first.
AI-amplified delivery, human review on every change
AI does the volume work: first drafts, audits, migrations, repetitive passes over a codebase. A senior engineer reviews every diff before it merges, and nothing deploys on its own. That is how a small studio ships at the pace of a much larger team without shipping the mistakes a larger team would find three weeks later.
Native in English, Spanish and Dutch
Multilingual is the default here, not an add-on at the end. We write, build and support in three languages, with a route per language, translated URLs, reciprocal hreflang and copy that reads as if it had been written locally, because it was. That matters in Europe and the Americas, where the buyer and the guest rarely share a language.
Built to be found by people and by AI
Every site we ship serves real HTML to crawlers, with structured data generated from the same source as the visible text, honest modification dates and a robots policy that lets the answer engines read you. Most sites built in the last five years serve an empty shell instead, which is why assistants never mention them.
Polargate is POLARGATE, S.L., a Spanish company with its registered office in Madrid and a working base in Amsterdam. It was founded by Pedro Ciordia, who leads every engagement and brings more than fifteen years across enterprise business intelligence, semiconductors, hospitality and consumer products. Specialists join by name, per project, and leave when the project ends.
Insights
Notes on the work: how AI search actually reads a website, what a paid Discovery Sprint produces, why a single-page application can be invisible to assistants, and how to choose a digital partner when you are the one who has to live with the decision. Written by the person doing the work and updated when the facts change.

Start with a Discovery Sprint
Two weeks, a fixed price from 4,900 EUR, and a written scope at the end of it: architecture, phases, risks and cost, in a document you keep whoever builds it. If the honest conclusion is that the project should not be built as planned, that is a valid outcome and you still keep the document. Send the brief at /start, in English, Spanish or Dutch.
