Senior software, native in AI

Polargate. We build software for mid-market companies.

A senior studio that builds your software with AI and keeps it running in production.

First step: a two week Discovery Sprint that closes the price before anything is built.

We work for hotels, travel, industry, legal services and live music in Europe and the Americas.

What we do

Three lines and AI in all of them.

Polargate is a senior-led, AI-native digital studio for mid-market companies in Europe and the Americas, working natively in English, Spanish and Dutch. It builds websites, products, internal portals, mobile apps, AI features and integrations, makes them findable in search and AI assistants, and maintains them on a monthly retainer. Every engagement starts with a paid, fixed-price Discovery Sprint.

For example: 90% resolved within the hour, p90 around 59 minutes. Estevano

How we work

From brief to production.

Every project starts with a paid Discovery Sprint that closes scope and price, and every change goes through the same loop of building, auditing and fixing until two passes come back clean.

The studio

Why Polargate.

  1. 01

    Senior-led, with no junior layer

    The people who scope your project are the people who build it.

  2. 02

    AI-amplified delivery, human review on every change

    AI does the volume work: first drafts, audits, migrations, repetitive passes over a codebase.

  3. 03

    Native in English, Spanish and Dutch

    Multilingual comes as standard.

  4. 04

    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, accurate modification dates and a robots policy that lets the answer engines read you.

For example: 536/536 translation keys present in each of the three languages. Estepona Golf

FAQ

Frequent questions.

What does Polargate do?
Polargate builds, grows and maintains custom software for mid-market companies. BUILD covers websites, products, internal portals, mobile apps, AI features and integrations. GROW covers SEO, AI-search visibility, content, paid media and analytics. CARE is senior maintenance and evolution on a monthly retainer, run through a ServiceDesk. Most clients start with one track and add the others once the first one is running.
How much does a project with Polargate cost?
Every engagement starts with a paid Discovery Sprint, which ends in a fixed price for the build itself. Care keeps live software maintained on a monthly retainer, Grow adds search, content and campaigns on top of Care, and standalone audits have their own fixed price. Polargate does not bill by the hour, does not publish a price list and does not quote a build before Discovery has defined it. Book a call and you get a first read of scope and price, then a private quote.
How fast can you deliver?
The first production iteration usually ships four to eight weeks after the Discovery Sprint, and Discovery itself takes about two weeks. Speed comes from senior engineers working with AI. Review is never skipped. Larger platforms are shipped in phases, so something real is live and usable early instead of everything arriving at the end.
Who does the work?
Senior engineers, and the people you meet are the people who write the code. Pedro Ciordia, founder and CTO, leads the technical direction and Andrés Ciordia, Chief AI Officer, leads the AI work. Photography, design, content and native development come from specialists we bring in when the project needs them. There is no junior layer learning on your budget and no account manager between you and the build.
Do you work with our existing stack, or do you rebuild everything?
We work with what you have whenever it holds up, and we say so plainly when it does not. Polargate has taken over WordPress and WooCommerce sites, integrated hotel booking engines, Microsoft 365 and Entra ID, bank payment gateways and third-party APIs. The default for new work is React and TypeScript with Supabase and Vercel. The Discovery Sprint decides repair or replace, with the cost of each written down.
What happens after launch?
Either the work moves to a Care retainer or it does not, and either way you own everything. Care is a monthly retainer: requests enter a ServiceDesk, are estimated in hours against a contracted pool, and a monthly audit covers security, structured data, AI-search readiness, performance and broken routes. Repository, database, hosting, secrets and domains stay in accounts in your name, with a written handover if you leave.
Where is Polargate based?
Polargate is POLARGATE, S.L., with its registered office at Calle Electrónica 6, 28027 Madrid. It works from Madrid and Amsterdam. Client data sits on European infrastructure by default.
Which languages do you work in?
English, Spanish and Dutch, natively, in meetings, documents, code and support. Polargate also ships sites in other languages when a market needs them, for example a Spanish, English and French golf site with a translated URL per language. Multilingual work is built properly: one route per language, reciprocal hreflang, per-language metadata, and content written rather than machine translated.
