Born into a family of lawyers and theater producers, Palazzari attended the Francesco Morosini Naval School in Venice and pursued a law degree at La Sapienza University in Rome. In his early 30s, he relocated to Milan, driven by a fascination with the design industry, and transformed a custom lighting production workshop into what is now Nemo Lighting Group.

Since acquiring Nemo in 2012, Palazzari has collaborated with renowned designers and architects, including Álvaro Siza, to create innovative lighting solutions. Under his leadership, Nemo has expanded its global presence, becoming a leading name in contemporary lighting design.
