Vestiaire Collective promotes CFO Bernard Osta to CEO role
Luxury fashion resale platform Vestiaire Collective has promoted Bernard Osta to the role of CEO, succeeding Maximilian Bittner who has led the company for the past seven years.
Osta has been part of the Vestiaire Collective journey since May 2021, initially holding the position of Chief Strategy Officer up to August 2023, followed by taking the role of Chief Financial Officer from September 2023 to September 2025.
Before joining Vestiaire Collective, Osta spent time advising businesses strategically as an investment banker for 15 years at Lazard (2006 to 2011) and Goldman Sachs (2011 to 2021), in New York and Paris.
In a statement regarding the departure of Bittner and the new appointment of Osta, the board of directors of Vestiaire Collective jointly said: “We want to thank Maximilian Bittner for his dedication and the significant role he has played in the development of the company since he joined in late 2018.
“We wish him every success in his future professional projects. Looking forward, we are very happy to open a new chapter under the leadership of Bernard. We have worked very closely with him since he joined Vestiaire Collective.
“His intimate knowledge of the company, international experience and great leadership will be invaluable assets for Vestiaire Collective in its next phase of growth.”
Osta added: “I am very honoured to take the role of CEO of Vestiaire Collective and lead the highly talented team we have built over the years.
“Vestiaire Collective has secured a unique position as the ultimate trusted marketplace in the highly attractive pre-loved luxury fashion industry. Together, we will continue to transform fashion by giving a second life to the most desirable pieces, at the service of a more sustainable model.
“This is a particularly exciting moment for the company. With the rise of AI, we have an extraordinary opportunity to accelerate on our product roadmap, deliver the most engaging customer experience and gain market share.”
Under Osta’s leadership, Vestiaire Collective will continue to invest in its leading authentication capabilities “to further confirm its strategic position as the ultimate trusted marketplace in the pre-loved fashion industry”, as well as its marketing initiatives across Europe, the US and APAC.
In April, Vestiaire Collective launched a data-driven Resale Buying Guide for SS25, described as a “comprehensive analysis of the second-hand landscape today”.
Leveraging historical data and proprietary analytics, the guide identified the brands, pieces and key trends driving the resale market for the season.
