What we do

Three lines of work, one team

We do not resell licences or subcontract the build. We design, code, deploy and maintain what we deliver, so the person who answers the phone is the person who knows the code.

Custom software for organisations

Management platforms built around how your organisation actually works, not around what a generic product allows.

  • Members, fees and billing
  • Internal portals and back offices
  • Digital forms and paperless processes
How we build it →

High-quality websites and ecommerce

Fast, accessible sites that hold up on the day everyone visits at once: registration opening, a final, a campaign launch.

  • Corporate sites and landing pages
  • Online shops and payment gateways
  • Technical SEO and Core Web Vitals
What is included →

Specialists in the sports sector

More than ten years working with federations, clubs and athletes. We understand the licence, the calendar and the match report before you have to explain them to us.

  • Federations and delegations
  • Clubs and sports schools
  • Athletes and families
How we work in sport →

Integrations and APIs

We connect what you already use: payment gateways, accounting software, federation systems, CRM and email. No duplicate data entry.

Hosting, domains and infrastructure

Managed servers, backups, certificates and monitoring. We take responsibility for uptime instead of pointing at the provider.

Digital marketing

SEO, SEM, campaigns and social media planned around the product, not as a separate department that never talks to the developers.

Integrations

It has to talk to what you already have

Most organisations do not need to replace everything. They need the pieces they already paid for to stop being islands. We map every system, agree what is the single source of truth for each piece of data, and connect the rest.

  • Card, Bizum and bank transfer through a single gateway
  • Automatic reconciliation against your accounting software
  • Documented API so you are never locked in

Websites

Built for the day everyone arrives at once

A website earns or loses its reputation in a handful of hours a year: a deadline opening, a campaign launch, a call for applications, a sale. We build for that peak, and the rest of the year has room to spare.

  • Load tested before it reaches production
  • Accessibility as a requirement, not an extra
  • Editable by your team without calling us
Pre-launch checklist Template
01 Performance budget Agreed with the client before design OK
02 Peak load test Traffic peak simulated before launch OK
03 Accessibility review Contrast, keyboard, screen reader OK
04 Editor handover Session recorded for the team Scheduled

Our own product · Sport

MatchReady: what we build, running every weekend

The best proof that we can build your platform is the one we already run. MatchReady manages licences, fees, competitions and public websites for more than 500 clubs and 20 federations across Spain.

Clubs

Members and fees

Everything about the person who pays: sign-up, subscription, receipts and communication.

  • Members and users
  • Subscriptions and services
  • Invoicing and receipts
Licencias

Licences, paperless

The federation process end to end, from the medical form to the printed card.

  • Licences and registered players
  • Delivery notes and invoices
  • Medical reports and cards
Competiciones

Competition management

From drawing up the calendar to settling the referees, with digital match reports in between.

  • Competitions and calendars
  • Digital match reports
  • Referee settlements
Web+

Websites for clubs

Our website system for sports clubs, fed straight from the platform so nobody copies a result by hand.

  • Website integration
  • Squad and player pages
  • Fully customisable

Same team, same code, same phone number. If MatchReady does not fit your organisation, we build what does.

Our own product · Payments

PayReady: every way of paying, under one umbrella

Collecting money is where most projects for organisations break. PayReady is the virtual POS we built for our clients so that it stops being a problem.

We integrate it into your portal ourselves

We do not hand you API documentation and wish you luck. Our team connects PayReady to your website or your platform, and we are the ones who answer when a payment fails on a Sunday morning.

  • One provider for every payment method, one set of fees to understand
  • Integrated into each client portal by our own team
  • Payment links for everything that does not go through the website
  • Every payment tied back to its receipt in your management system
Virtual POS Card payments on your own website, with the checkout in your brand.
Apple Pay One tap on iPhone, no card numbers typed in.
Google Pay The same on Android, with the card the user already has saved.
Bizum Immediate payment from the phone, no card details and no transfer.
Bank transfer For large amounts and for anyone who still prefers the bank.
Payment by link Send a link by WhatsApp or email and charge without a website in between.

Method

Five stages, in this order

Each stage ends with something you can see and approve. You never wait months to find out whether we understood the brief.

01

Discovery

Workshops with the people who will use it. We leave with a functional definition, not a wish list.

02

Design and prototype

A navigable prototype you can click through before a single line of production code exists.

03

Iterative build

Short cycles with a working version at the end of each one. You see progress, not status reports.

04

Go live

Data migration, load testing and training for your team before the switch is flipped.

05

Support and evolution

A named contact, agreed response times and a roadmap that keeps moving after launch.

Case studies
