Our Story

The company was founded in Rome in 2015 by Alessandro Mattei and Caterina Naglieri, both architects. After working in several European cities in the fields of construction, interior design and research, they decided to return to their own city and launch a creative company. Plato Design first project D-TWELVE lamp was produced thanks to a successful crowdfunding campaign on Kickstarter. The project was on show at Fuorisalone di Milano, Maker Faire Rome and Moacasa, and was also awarded with Regione Lazio Fund for Creativity, Inarcassa Premia le Idee Prize and Maker Faire Blue Ribbon.


Alessandro Mattei, 1980, architect, designer and craftsman. He studied arts and architecture in Italy and Spain, and then worked as an architect for international companies in Italy and Poland. Moving back to Italy he founded Plato Design. Exceptionally creative and always keen on light design, he designed his first lamp at the age of six.


Caterina Naglieri, 1982, architect and PhD in Environmental Design, studied in Rome and Lisbon. She has worked as teaching assistant in Sapienza University and later as architect for international firms in Italy, Poland and Spain. Moving back to Italy she joined Alessandro in founding Plato Design. Passionately fond of sustainability and innovation, she is the rational side of the company.

At Plato Design things are invented, prototyped and handmade,

merging clear design with technological innovation and unique “made in Italy” handicraft.
