We create products that we wish existed,
explore new territories and dedicate our work to imagination with a human-centered approach,
as we believe that design has an added value to the world, apart from aesthetics.

Cristina Dan

Solve is an award winning multi-disciplinary social innovation studio in design and sustainability, whose expertise lies in

co-creating solutions for the circular economy through design, within the fashion & lifestyle industry. The studio’s design work is strongly connected to the academic research that Cristina Dan, the founder of SOLVE, conducts in circular fashion design. 


We work with design thinking, new technology, and circular economy to co-design sustainable innovations, offering design and consultancy services.


The results of Cristina's research also translate into circular fashion products that we carefully manufactured in our studio and sell online via our webshop.   

We engage with enthusiasm in collaborations with companies, public institutions, NGO’s and researchers that share our vision of bringing to life circular products and systems within the fashion and lifestyle industry.


Through design we act as a binder for circular fashion stakeholders and wish to scale the impact of our knowledge and help create new agents for change. Hence we enable companies to create products and product-service system innovation for a circular economy. 

Form Follows Feeling.
