How we work
For creating user-centric and user-desired apps, we use our R2D Product Growth framework. The R2D Product Growth framework consists of a series of iterations that solve three key objectives for our clients:
The R2D Product Growth Framework is a roadmap of a project that we assemble from necessary 2-week cycles depending on the business needs. According to this framework, a high-level roadmap looks like this:
R2D Product Growth Framework
To create our proprietary framework, we integrated all development stages with their respective best practices.
The main idea of the framework is that during the development of the product, we constantly prioritize the tasks required to be solved ASAP and proceed to the respective cycle. This approach allows us to run two or more cycles in parallel. Our R2D framework is a practice-oriented approach that has been used to deliver more than 250 successful software development projects. Unlike Agile, for each cycle, our framework offers proven results-driven stages and methods, which were carefully evaluated and chosen over the span of 10 years across hundreds of development projects.

The framework allows you to reach the expected results, transform chaotic ideas and feedback from the market into specific features, and keep on continuously delivering values to users in a changing market.
