The company SIGEA HOLDING, a leading company in the building sector, started its business in the early sixties, when Louis Grigoletto, the Daniel's father, established a small proprietorship “Grigoletto Costruzioni” at Via Burago in Villa di Salò.

The tenacity and the entrepreneurial spirit that characterized Mr. Grigoletto senior, became fundamental to the growth of the company which grew and consolidated thanks to quality.

The quick growth allowed the company to reach an excellent visibility in the building field and helped to acquire assignments for the execution of public works, construction of industrial buildings and urbanization works besides residential complexes. All this contributed to the development of the company which had subsequent corporate changes.

The first corporate change took place in 1986 when after the father‘s death, Danilo got the company going and brought it to the maximum development. The experience gained by the father enabled Danilo Grigoletto to adapt to the market progress and invest in research of new state-of-the-art construction methods.
