My name is Eva Wissenz. I’m a social and impact entrepreneur based in Tampere, Finland. I am the founder of Sepia Agency and the co-founder and chairperson of Solar Fire Concentration Oy. Before moving to Finland, I had a long career as free-lance and corporate in France. I wrote 12 books published in French.

My DNA is entrepreneurship with purpose, I have done it all and that’s why I want to help you to have a real impact in life. My experiences working as a corporate, a free-lance and entrepreneur, have made me flexible, rigorous, organized, creative. I’m passionate about sustainability and focused on ethics and quality.

I have 8 years experience managing international partnerships, handling communications, providing mission logistics in developing countries (India, Kenya, Tanzania, Uganda, Haiti, South Africa), and multi-cultural team management for my company. I worked at the intersection of clean tech, education and agro-food sectors.

Before I became an entrepreneur in Finland, my first background is in education and I was assistant in literature during my PhD at Paris-La Sorbonne. I wrote and published 12 books in French (novels and poetry). I worked many years in Paris as an editor, author, journalist and translator- with a special focus on culture, sustainable tourism, agriculture, food, positive communication and clean energy. I have been Director of Publications of Paris Tourism Office and Website Chief Editor implementing the communication strategy with supervision of several collections, management of Paris city guides, brochures and maps in 9 languages, production of all internal reports and transition to use of recycled paper.
