I am Marena Eirich, founder of teams4purpose®.

I am German-Venezuelan living in Paris and I consider myself a global citizen.

I studied International Management at l’ESB Business School in Reutligen, Germany and ICADE Madrid, Spain.

After a 15 year career in Marketing and Communications at international level, working both at local sales offices and headquarters across Europe, I left the corporate world in 2015 to study again.

BSL HSGI did an executive program on “Sustainable Business”at the Business School Lausanne  and St. Gallen University in Switzerland, which enabled me to better understand how Sustainability is a formidable business opportunity for positive impact.



cropped-image-1-1.pngBased on my « corporate », startup and consulting backgrounds and my conviction that EVERYONE can be a change agent, I founded teams4purpose® in 2018: a programme that empowers organizations and its employees to take action for positive impact and makes action on Sustainability and CSR accessible.


I love to co-create and work in network mode.

I believe that in order to solve the challenges of the 21st century, collaboration will be more crucial than ever. This enables me to continue learning, create a support system and very often get better results.

I co-founded 2 ventures :

logo VertuoseVertuose.fr, a social start-up, active in e-commerce and the Circular Economy. This experience enabled me to step out of my comfort zone, doing Biz Dev, Digital Marketing, people management and many other things. It also enabled me to grow, to co-create a company from scratch and live “agility” on a daily basis.

Logo with claim FINALAfter my executive education Business Sustainability, I co-founded The Sustainability Tribe, a network of independent sustainability experts, with whom I regularly collaborate, enabling me to learn from my peers and to add my hard and soft skills to co-create and
enrich our common offers.

Sustainability and me 🙂

The more I know about Sustainability, the less I know (Aristotle) … AND that’s OK because what counts is to give the best of ourselves and find new ways of doing things to accelerate the transition and co-create a livable future. !

Also, I am convinced that everyone can contribute to co-create a better world – especially at work, where we spend most of our time a day! 

What a great opportunity to add meaning to our jobs!
