Our history

Founded in 2014 in Poland, Leger Invest was born from the vision of our leader, who, after moving with his family, recognized the growing need for solutions to the labor shortage. We quickly launched Premium Outsourcing, marking a decisive turning point in our approach by becoming an agile HR solutions broker. This transformation has allowed us to increase our flexibility and better respond to the diverse demands of our customers.

In 2018, we innovated in the sector by being the first to adapt the management of foreign temporary workers, by transitioning to contracts under French law, particularly for our operations in France. This decision underlines our commitment to ethics and responsibility, placing people at the heart of all our actions.

In 2024, we are reaching a new level with the launch of GrowSo, symbolizing an expansion of our services and our growing ambition towards a more marked international presence. GrowSo represents our ongoing commitment to effectively meeting the global needs of our customers while maintaining the highest ethical standards.
