What our clients say…

I would recommend Rethink Rebels to textile companies that really want to work on sustainability and produce responsibly, but need a helping hand to apply complicated concepts. They work correctly, professionally and deliver quality, playing a connecting role between the technical expectations from politics, the concerns of the clothing consumer, and the practical reality of the production of clothing companies.

I feel super lucky to be able to work with Rethink Rebels and have conversations like this to further accelerate the transition towards the sustainable fashion industry. I’d recommend their services to anyone who is interested in sustainable fashion, let it be someone who wants to be sustainable in his/her daily life or someone who works in the fashion industry. From fashion designers through small brands to big organisations I believe everyone can take something home and implement your knowledge in practice.

Rethink Rebels is a perfect fit for our company. With their commercial experience, can-do attitude and immense drive for change, they have not only helped us in only a few months to set up a clearly defined strategy, but also initiated multiple immediate actions, have motivated stakeholders throughout the company and in addition, as one of our sales managers explained it, “they has made sustainability fun!”
