Founded in Hong Kong in 2016 by the French couple Delphine Lefay and Diego Dultzin Lacoste, OnTheList is a leading premium flash sales concept in Asia and the Middle-East. OnTheList works to minimize the problem of excess stock by turning past-season inventory into sustainable opportunities. OnTheList works directly with retail brands and official distributors, turning old inventory into opportunity by providing a sustainable way for brands to sell past-season items that would have otherwise ended up in landfills, while providing the best deals and steep discounts to our OnTheList members. Since launching in Hong Kong in 2016, OnTheList has hosted over 5,200 flash sales and has built a community of over 1.3 million members across all regions. We’ve since expanded to Singapore, Australia, Malaysia, Korea, Shanghai, Beijing, Thailand, and Dubai.

Sustainability is rooted in who we are and motivates us to continue our mission. To date, we have saved over 8.2 million items from ending up in landfills. Forming OnTheLove, our CSR initiative, has allowed us to deepen our commitment to minimizing our carbon footprint while working with local organizations and hosting regular charity sales.

At OnTheList, our values guide everything we do: Family Spirit is driven by humility, fostering genuine connections with our community. Panache reflects our passion for delivering exceptional experiences, while sustainability is rooted in our commitment to creating a positive impact on the world around us. Excellence is driven by the cooperation of our teams.
