Vestiaire Collective
Vestiaire Collective, founded in 2009 as “Vestiaire de Copines” by Fanny Moizant, Sophie Hersan, Sébastien Fabre, Alexandre Cognard, Henrique Fernandes, and Christian Jorge, began with 3,000 pre-owned fashion items sourced from friends and family. Rebranded in 2012, the company expanded internationally, starting in the UK and then the US, growing to operate in over 70 countries worldwide.
Under the leadership of Global CEO Maximilian Bittner, who joined in 2019, Vestiaire Collective shifted its focus towards promoting circularity and increasing its US market presence. Bittner, a tech entrepreneur known for founding Lazada Group, brought a wealth of experience, having previously led the company through rapid growth before its acquisition by Alibaba.
In recent years, Vestiaire Collective has been recognised for its commitment to sustainability. In 2020, it earned the distinction of being the 11th French Unicorn and became a Certified B Corporation in 2021. In line with its mission to tackle textile waste, the company launched a three-year plan in 2022 to ban 63 fast fashion brands, advocating for more conscious consumption.
The company’s growth continued in 2021 with significant funding rounds, raising €356 million in total, led by industry giants such as Kering, SoftBank, and Tiger Global Management. By November 2023, its valuation reached €1.1 billion. Fanny Moizant and Sophie Hersan were also recognised with the “National Order of Merit” by the French Ministry of the Economy in December 2023 for their leadership in sustainable fashion.
Vestiare’s resale platform creates potential benefits to citizens, business and the environment including shifting from fast fashion to trading up to a mindset of fewer, but better quality, second hand items; lower price points make luxury brand items accessible to a larger customer base; 48% of second hand shoppers admit purchasing a brand that was new to them and nearly all would consider buying these brands again; and by 2027, resale apparel is expected to make up 11% of an average citizen’s wardrobe.
