Ábil Score is an innovative app that goes beyond traditional stock analysis. It measures customer satisfaction using the Net Promoter Score (NPS) system and crosses this data with the quotes of companies listed on B3 and Nasdaq. The proposal is to offer a more complete view, where the performance of shares is analyzed both by the market and by the perception of customers, those who matter most. It is an essential tool for investors who seek to go beyond the numbers and explore the connection between customer and market.
