"За породицу" is an enhanced version of the project "Proud CardPrice minus for 3+". The aim is to increase the number of businesses offering discounts on their goods and services to families with three or more children and contribute to their businesses. Participants in the project have access to a unique electronic sales platform where they can showcase their products and services for free.

The app also features "Proud Market RS," designed as a business incubator primarily for food producers from families with three or more children. Through the app, these producers, often in the Startup phase, can market their goods to other families with three or more children and the broader market. The goal is to support production development among these families in the food and artisanal products sector and connect them with the market.
