Zadaa is a modern technology company and one of the fastest growing European startups. Zadaa’s vision is to connect every wardrobe in the world within the next five years.

Zadaa is a fashion marketplace that helps you to sell and buy clothes that fit by connecting people with a similar size and style. This way every user can find much easier clothes to buy that fits them perfectly, and sell their own clothes to people alike faster than ever before.

The brilliance of the company lies in Zadaa’s superior logistics technology. Physical location of the sellers and buyers doesn’t matter anymore – everyone in Zadaa are connected to each other, even cross-border. The Zadaa Package enables the cheapest and easiest consumer package to deliver items directly from people to people. These pre-paid packages are sent for free with a single code, and everything is integrated in the app.

The company was launched in Finland in 2016 and operates now in Finland, Denmark and Sweden. We have grown our network to over 150 000 Zadaa users collaborating with hundreds of clothing brands, local designers, fashion and lifestyle influencers. There are currently over 500 000 unique pieces of clothes for sale in the app.

Since the launch we have raised 1,2M euro in funding and are currently closing an additional 3M euro A round. We are backed by the most well-known Finnish and Swedish investors and VC’s such as Superhero Capital, Leena Niemistö (FIN) and Moaffak Ahmed (FIN), Paul Källenius (SWE). We have been rewarded with multiple awards, Forbes nominated our CEO Iiro Kormi on the list of 30-under-30 in retail and e-commerce and we have featured by Apple in their webpage and App Store.
