Our digital development process

We believe that the key to success is constant communication, through which we can respond effectively to all requests and questions. The end result is guaranteed to be a product that meets all previous expectations.
OUR PORTFOLIO

1.

Ideas, workshops

In the beginning, there was the idea. Only 10% of digital product ideas become successful products and are able to provide value to end users. The brainstorming phase serves to see if the digital product can avoid initial failure. Traditionally, this phase is about identifying problems, technical limitations, and ideas and coming up with solutions.

Design

From the first meeting to the wireframe: after assessing the needs, we prepare the functional specification for the project and design the product, so you can already have the wireframe of the app or software in hand! Using this as the basis, we draw up a personalized, detailed offer and project schedule.

MVP Product Release

A minimally viable product is aversion that has the most important functionality and user interfaces. This step in digital product development is essential to validate the idea. In addition, it allows you to learn from user feedback. An MVP can be either a working prototype or even a simple idea visualization, depending on the approach you choose to create an MVP.

Go-to Market and Product Development

1The life of the product after the introduction is a kind of a maturing period. In general, it is characterized by customer support/support tasks, updates, development of new features and sustainable product development. The fundamental objective of continuous improvement is to ensure that the product evolves, renews itself, keeps up with trends, improves the user experience and meets new needs.
