Marina Sersale was born in Rome, Italy, to an Italian father and an English mother. Through her father she is part of the family that created and still owns the award-winning 5-star hotel Le Sirenuse in Positano, Italy. Growing up she split her time between England and Italy and built a career as a documentary filmmaker.
Sebastián Alvarez Murena was born in Buenos Aires, Argentina to a family of writers. After living in Argentina, Spain and Switzerland, he settled in Rome where he worked as a journalist and in 2001 met Marina.
The two fell in love and got married. In 2004 they joined forces with the creation of Eau d'Italie, an exclusive collection of fragrances, body care and home fragrances, inspired by Positano and their favourite places throughout Italy.
In 2012 the chance discovery of the extraordinary events that centuries ago linked their families in Argentina inspired them to create a new fragrance brand, which they called ALTAIA.
