Founded in 1940 by Mr. Alejandro Amilibia Echeverria and Mr. Facundo de la Iglesia Martín, AMIG began in Bilbao, manufacturing small pieces such as shoe defenses, buckles or suitcase closures.

Little by little the company is growing until reaching 232 workers, evolving its production towards hardware items and fittings for the door, and moving to a larger factory in Durango.

At the end of the 1990s, the company opted for innovation in manufacturing and storage, and in 1998 it moved to a more modern factory in the town of Amorebieta.
