The need for European reindustrialisation has boosted the debate on regional path creation. Through a business case approach, this work contributes to this literature by exploring the history of Daniel Alonso Group, a paradigmatic example of an entire sectorial trajectory. Born in the steelmaking region of Asturias (Spain) in 1957 as a small metalworking workshop, DAG is nowadays represented worldwide by Windar Renovables, a top firm in the wind power sector. DAG reflects the 3-stage cumulative process that allowed the Asturian metalworking sector to survive industrial restructuring and create new development paths: (1) birth around the steelmaking industry, (2) endogenous growth based on self-reinforcing dynamics (3) delocking, diversification, and international expansion moving towards Industry 4.0.
