Process

A simple process with no surprises

You always know what is being built, what it costs and when it ships.

  1. Step 1

    Discovery call

    A free call to understand your goals, users and budget. You get a clear plan and a fixed quote.

  2. Step 2

    Design

    Wireframes and designs you can click through before any code is written.

  3. Step 3

    Build

    Short cycles with a live preview link, so you see progress every week and can steer.

  4. Step 4

    Launch and support

    We deploy, publish to the app stores, set up monitoring and stay on to maintain and improve.

FAQ

Questions we get asked a lot

How much does a website or app cost?

It depends on scope. After a free discovery call we send a fixed quote, so you know the price before we start. A business website costs far less than a custom mobile app or platform, and we can phase larger projects to fit your budget.

How long does a project take?

A business website usually takes 2 to 4 weeks. A first version of a mobile app or web platform usually takes 6 to 12 weeks. We agree on a timeline before work starts.

Do you only work with clients in Cyprus?

No. We are based in Limassol, Cyprus, and work with clients in Cyprus, Greece, the rest of Europe and worldwide, remotely in English or Greek.

Do you build both websites and mobile apps?

Yes. We build websites, web applications, iOS and Android apps, and the backend systems behind them, so you have one team for the whole product.

Who owns the code and the accounts?

You do. Code, domains, app store accounts and cloud accounts are in your name, and you get full access from day one.

Do you offer support after launch?

Yes. We offer ongoing maintenance, hosting management, updates and new features after launch.
