SiSustainable


SiSustainable was created in Finland in 2009 by Eerik Wissenz, a GNU/Linux enthusiast.
On some projects he works with his wife Eva, who also runs her business Seepia Publishing (ecological resources). When required they don’t hesitate to complete their skills with independent friends.

They are accustomed to work at a distance as well as integrate into a team. They can communicate in English, French, Italian and Spanish.

Eerik Wissenz grew up in Canada and studied mathematics at Ottawa and Carleton University, but quickly took a hiatus to dedicate himself to developing solar thermal technologies. He completed his Finnish defense forces service in 2004 as a class A infantry. Participating in, leading and organizing solar projects in Central America, Europe, Africa and India, Eerik is striving to push the boundaries of where solar thermal can go and so he founded Solar Fire Concentration Oy in 2012 .

Passionate writer, bilingual in French, convinced by Open Source culture, Eerik is currently also working on an open book on sustainability, Decentralized Democracy. He enjoys chess, guitar and nature, and loves living close to lakes and trees with his wife Eva and daughter in Tampere. He is Finnish-Canadian and speaks English, French and some Finnish.


With 15 years experience in publishing, Eva Wissenz can manage editorial services, translations, and communication in French and Italian.

She is a writer, publisher, translator and journalist member of the French JNE (Journalistes pour la Nature et l’Environnement). She started publishing her books in France in 2005, created writing workshops in hospitals, participated in many environmentalist associations and worked on solar energy since 2007. Her articles have been published in French reviews and ecological sites. She created her own publishing house in Finland, Seepia Publishing.

Eva has a DEA in literature and has taught as associated professor at La Sorbonne University (Paris). She has a strong experience in French publishing and media (Michelin Guide, Hachette and Gallimard, including chief editor for the Zurban Guides, chief editor at the Paris Convention and Visitors Bureau). For the web, she was chief editor of the new version of the Paris Convention and Visitors Bureau and editor for Nomade Aventure’s website. She has translated over a dozen works (published in France by Allia, Actes Sud, Fayard...) and has done live transcription at the Autumn Festival of Paris and the Festival of Palermo.
