Marco was born in the Wilhelmina Hospital in Alkmaar, the Netherlands as the son of Italian Roberto Borsato and the Dutch Mary de Graaf. His family moved to Italy, where his father opened a restaurant at lake Garda (Lago di Garda). Marco has spent a lot of time in Italy and speaks fluent Italian.

Marco gained his fame after winning the Soundmixshow on the 7th of April 1990 with his representation of the song At This Moment. After winning the contest he made three Italian albums. However, they were of limited commercial success. In 1994 he switched to singing his songs in Dutch (of which many are translations of Italian songs). His big breakthrough was the song Dromen zijn bedrog which remained at the number 1 position for 12 weeks, which is still a record in the Dutch Top 40.

Marco is married to Leontine Ruiters and they have three children: Luca (1998), Senna (2002) and Jada (2003). His favorite artists are Paskal Jakobsen, Bløf, Paul Carrack and Phil Collins.
