Software development

From idea
to working product.

The technical and design team behind your product, from the first line of code to launch day.

You work directly with senior engineers. We use AI-assisted workflows to move faster, while every product and technical decision stays in experienced hands. You see working software every week, and you own the code.

What we solve

The problems
we solve for you.

Founders come to us stuck in one of three places. Whichever one you are in, you get the same team and the same weekly rhythm.

You have an idea, but no product.

We build the web product end to end — product definition, the core user journeys, the database, the backend, the interface, and production deployment. You get working software on secure foundations, plus the source code and a technical handover.

It works, but nobody trusts it yet.

Branding and UX/UI design led by a senior designer: a visual identity, high-fidelity screens for the journeys that matter, and a reusable design system. The product stops looking like a prototype and starts looking like a company.

Your users live on their phone, not a browser.

Mobile app development for iOS and Android, including the store accounts, the review process, and publication to both the App Store and Google Play. We handle the parts that usually stall a launch.

How we do it

No black box.
You steer, every week.

Most software projects go quiet for months and reappear as something you did not ask for. Ours never leaves your hands: you see the product every week and decide what happens next.

  1. 01

    Free project proposal

    Together we define the problem and the core user journey, the constraints the product has to live with — data, integrations, performance — and where the first release stops. You get it in writing, in plain language. The proposal is free and it is yours to keep, even if we never work together.

  2. 02

    Scope agreed in writing

    Nothing is built until you have approved that scope and we have the content and access we need. No surprise invoices, no quiet expansions — if something needs to change later, we agree it with you first.

  3. 03 Every week

    Weekly sprint with your Client Companion

    Every week, in the same slot, your Client Companion shows you the working software we built last week, answers your questions, and plans the week ahead with you. Blockers and unknowns come up in that meeting, not three months later — so we adjust instead of building the wrong thing.

  4. 04

    Launch and handover

    We deploy to production and hand over the source code, the infrastructure, and the documentation you need to run it. You own the product outright. From there you can keep us on to build the next sprint, or take it from here yourself.

One or two conversations are usually enough to get started. The proposal is free, and it is yours even if we do not end up working together.

FAQ

The questions everyone asks

When will I see something working?
After the first sprint, and every week after that. We build in complete vertical slices, so what you see each week is a real, working part of your product — not a mockup or a progress report. You never wait until the end to find out what you are getting.
What is a Sprint?
At Studio Prats we work in weekly Sprints following the Agile methodology: each week we set the priorities and features to work on together with you, and deliver them the following week. Sometimes unknowns or blockers come up in a feature and, instead of building something wrong that you don't want, we touch base with you the next week to adjust.
Who owns the code?
You do — the source code, the designs, and the accounts, outright and from day one. A technical handover is part of every engagement, so you are never locked in to us. If you bring in an in-house team later, they inherit a documented codebase rather than a mystery.
What about hosting and infrastructure costs?
We cover the web hosting, database, and monitoring services we select during the build and for 30 days after launch. After that, you can ask us to maintain the product or take over the accounts and code yourself.
