Sunsundegui initially started out as a rolling stock repair workshop for Renfe, the Spanish state railway company. This practice continued until the 1980s, when Renfe began to open their own engineering workshops and ceased to use Sunsundegui's services; the company changed focus as a result, launching their first production coach, the Sunsundegui Korinto, in 1987. In 2017, Sunsundegui moved into a €5.5 million new factory in Alsasua.
