Our vision

We want to strive for a circular world without waste, where items and resources keep circulating to live a long life, and where nature has time to recover.

Our why

Did you know “The Swiss are the third most wasteful people in Europe” and as a consequence “If everyone lived like the Swiss we would need the natural resources of 3 planets”? Swishi exists to inform people about alternatives to “new” consumption, to shift mindsets towards throwing less away and to make conscious consumption easy. Together, we can reduce waste and slow down the extraction of our Earth’s resources.

Swishi’s Story

Swishi started when us sisters, Julia & Viktoria, decluttered our home in 2019 and learned how to use popular online marketplaces. In parallel, we discovered beautiful second-hand shops and new second life programs from brands like IKEA and Apple. We realised there were many more ways to declutter sustainably, but researching these options was very time-consuming for so many different kinds of items in our home. Through interviewing our friends we realised they have different preferences on how to give items a new life, some enjoy a flea market while others like to donate an item, and we noticed an unawareness of new trade-in programs from brands. 

We saw an opportunity to gamify the item afterlife experience, after having played video games trading Pokémon, as well as doing several sustainable impact university projects. Swishi matches items with their possibilities to motivate users to give their items a new life – the way they want. We make it easy to adopt a sustainable mindset and to contribute to the circular economy.

Happy sustainable shopping/decluttering everyone!

– Julia & Viktoria Rajnak, Founders


Swishi: a WIN-WIN-WIN solution!

Swishi is the first Sustainable Exchange & Recommerce Platform in Switzerland. Recommerce is about exchanging a second-hand product with businesses or individuals willing to reuse, recycle, repair or resell it. Recommerce is also known as resale or reverse commerce.

As an individual, on Swishi you can find a second-hand treasure at a low price, get rewarded with a discount for trading in your phone, get money from a local second-hand shop for selling your furniture, swap your book for a Pokémon card, repair or upcycle your favourite shoes, rent a new cocktail dress for your next afterwork – you choose what option works best for you and your lifestyle!

As a business, show your storefront digitally, connect and engage with sustainable customers and promote your contribution to the circular economy on Swishi. Why not have a B2B conversation and join forces with another business? You might need that handbag from a shop in Zürich, for your loyal customer in Geneva. With Swishi new kinds of interactions are made possible!

Together, it feels good to find the right home for items and give them a new life and purpose! Our diverse and inclusive organized directory informs you about your different trading options, to transition to a more sustainable world and do good for the planet.
