About us
BRANDS
The opening
of the company’s first franchised store the Original Levi’s® Store in
Guimarães, dates back to 1993. Since then, the organization has followed an
upward trajectory, both in the number of stores and in the quality of the
service provided, resulting in steady growth in turnover. The most recent
investment in Madrid took place in October 2025, when we took over the
management of four Levi’s® Stores in the Spanish capital, located in the
Plenilunio, La Gavia, Gran Plaza 2 and Plaza Norte 2 shopping centres.
Currently, and also considering the management of the website levi.pt, GNG
manages 85 franchised stores of the Levi’s®, Dockers® and Adidas® brands in
Portugal and Spain.

Values
The main objectives of GNG are to become a national and international reference in the management of clothing stores, offering the consumer a high level of service and satisfaction, based on ethics, respect and human values. Today, GNG is one of the biggest customers of Levi Strauss in Europe and a firm investment and future of Dockers and Adidas, driven by steady growth through a specified investment policy, based on the working capacity of its professionals and on the search for new markets. GNG aspires to be an example in the quality and rigour of its management methods. Innovation has been and always will be present. The company seeks to quickly adjust to the challenges that arise daily and to the constant changing realities in today’s world. The current economic environment requires greater tools and methods to strengthen the current resources. There has never been a greater need to increase employee’s capacities, measure effectiveness, optimise stores, calculate optimal stock levels and improve service quality, leading the company to invest more in differentiation and innovation factors. The path to excellence will be based on three main pillars: correct selection of clothing and rigorous management of stocks; customer service optimisation; monitoring all aspects relating to business, “real-time”, of various performance indicators and general business conditions. The path to follow is to invest in tools that strengthen and develop the business as previously referred. Partnerships with companies that add value to internal resources and make it possible to achieve this objective are a reality. If we combine the tools that are currently used with the new applications that we can safely say, will be unique in the world and have unparalleled potential for innovation, GNG will achieve superior results in store management. GNG is proud to have key strengths throughout its company: its fantastic interpersonal relationship, human values, healthy competition and its employees work capacity. GNG believes in the value of human capital.
