01 / WHAT’S INCLUDED
A first version that solves the right problem.
We start with the user and the task they need to complete. That gives development a clear purpose and a first release you can evaluate before investing further.
An interface for real use
Sign-in, search, forms, bookings or other tasks shaped by your idea. We design empty states, confirmations and error messages too.
Data, permissions and integrations
A data model, user authentication and server-side permission checks. Connections to available external APIs within the agreed scope.
Testing and future development
We verify key flows and acceptance criteria. Handover includes agreements on hosting, documentation, maintenance and future versions.
From choosing a time to a clear confirmation.
Our booking concept illustrates a complete small journey: selecting a service, an available slot and confirming it. A flow like this can form the starting point for an MVP.

BEFORE WE START
Common questions.
What is an MVP, and is it right for my idea?
An MVP is the first usable version of a product focused on its core problem. It helps you see how real users respond before making a larger investment. Scope depends on what you need to learn.
How is a web application different from a business system?
A web application can be a product or tool for external users. A business system organises company operations, such as CRM, work orders and a client portal. If internal processes are your priority, explore our business systems service.
Will the application work on mobile?
A responsive application runs in a mobile browser without installation. Offline use, push notifications and device-specific features require a separate assessment and are not automatically included.
Can you develop an existing application further?
Potentially, after reviewing the code, documentation, access and infrastructure. We then recommend improvements, stabilisation or a new build with an explanation of scope.
What should I prepare for an initial conversation?
Describe who would use the application, the problem it solves and one main task. Include sketches, an existing tool or integration requirements if available. You do not need a technical specification to start talking.
Do you work with companies and startups in Zagreb?
Yes. We work with companies and startups in Zagreb and across Croatia. Workshops, reviews and handover take place remotely, in Croatian or English.
