Working on projects for Adidas, IKEA, and other seriously good global brands, they built a process in which design, architecture, and analytics don’t live apart, but develop in parallel. This link allows not only to release applications faster, but also to calculate in advance how certain product solutions will affect user retention, involvement, and conversion.

The Appinventiv technology stack easily combines React Native, AI-modules for personalization, IoT-integrations and blockchain-functionality for secure transactions. At the same time, the team does not chase «fashionable» technologies for the sake of ticking – each tool they add to the project only after evaluating its real use.

As a result, customers get not just a beautiful frontend and working backend, but a complete ecosystem that fuel growth and scaling provides.
