Custom software development in Barcelona

We design, build and launch software made for your business: web platforms, internal tools, SaaS and the APIs that connect it all. It’s what we do every day with REPLAI, our AI operations platform: a single team, from first sketch to production server.

What we do

  • Web platforms and SaaS

    Complete web applications, for one company or multi-tenant, with roles, permissions and several languages from day one.

  • Backend and APIs

    The business logic, the data and the APIs used by your website, your apps and other systems.

  • Integrations

    We connect your software to calendars, CRM, e-signature and the tools you already use, without breaking what works.

  • Internal tools

    Dashboards, workflows and automations that replace spreadsheets and repetitive tasks.

  • Infrastructure and operations

    Deployment on AWS or Azure, support and new features once the product is live.

Who it’s for

  • Companies that need their own tool because off-the-shelf ones don’t fit the way they work.
  • Start-ups and teams that want to launch a SaaS product and run it from day one.
  • Organisations with several brands, sites, clients or languages on the same platform.
  • Teams that want to move manual processes into their own system and automate them.

What you get

  • A clickable prototype before any production code is written.
  • The application in production, with your brand and in your languages.
  • APIs to connect your website, your apps and other systems.
  • Infrastructure on AWS or Azure, ready to run.
  • Support and new features once the product is live.

How we work

  1. 01

    Understand

    We talk to you and to the people who will use the product to understand the problem and what to solve first.

  2. 02

    Design and prototype

    We design the experience and test it with a prototype before writing production code.

  3. 03

    Build

    The same team builds the product in increments, with AI in the process and regular reviews with you.

  4. 04

    Launch and run

    We put it into production on AWS or Azure, publish it where it needs to be and stay on for support and new features.

Frequently asked questions

What is custom software and when is it worth it?
It’s software designed around the way you work, instead of bending your business to a generic tool. It pays off when your processes are your own, when several systems need to work together, or when the software is part of what you sell.
Can you work on a system we already have?
Yes. We can integrate with what you already use or evolve it step by step, without breaking what already works. The first step is understanding what’s there and what has to keep running.
Do you also handle hosting and maintenance?
Yes. It’s what we do with our own products: infrastructure on AWS or Azure, support and new features. We design it, we build it, we run it.
Do you work with companies outside Barcelona?
Yes. We are based in Barcelona, but the work can be done remotely with companies across Spain and in other countries. We speak English, Spanish and Catalan.
How much does a custom software project cost?
It depends on the scope, so we don’t publish prices. Tell us what you need using the contact form and we’ll reply by email with the next steps.
