YOOX Net-a-Porter Group S.p.A. is an Italian online fashion retailer created on 5 October 2015 after the merger between Yoox Group and Net-a-porter Group (NAP).
Yoox was originally founded by Federico Marchetti in Milan in 2000, and Net-a-Porter was founded by Natalie Massenet in London in 2000. Beginning in 2003, Richemont invested in NAP. In 2015, Yoox purchased NAP shares from Richemont and merged with Net-a-Porter to establish the Yoox Net-a-Porter Group. In May 2018, Richemont acquired the YNAP Group by purchasing 95% of the company's available shares. The combined company has become a global e-commerce player that serves more than 180 countries. YNAP posted a €1.46 billion loss in 2023, and in October 2024 Richemont agreed to sell Yoox Net-A-Porter to Mytheresa.
