The first step
José Cardoso founds Grupo JAF in Guimarães. Construction is the point of departure, and the will to grow is the engine.
We started in 1999, in Guimarães, with construction as the point of departure. Since then, we have turned on-the-ground experience into new capabilities, new projects and new markets, without ever losing closeness, rigour and a long-term view.
Grupo JAF’s history is one of entrepreneurship and adaptation. We were born in construction, but never stayed tied to it: we gradually broadened the business into complementary areas, consolidating technical capabilities and expanding our presence beyond Portugal.
José Cardoso
“Grupo JAF was born in 1999. Building on experience in construction, we grew and diversified with a clear focus: delivering projects, developing teams and investing in areas with long-term potential.”
José Cardoso, founder
Leadership that stays close to the work, geared to delivery and to creating sustainable value.
