My Name is Franz Geffke - I was born and raised in East Germany but today my home is anywhere between Europe, the Middle-East and Southeast-Asia. New experiences and culture draw me to travel to, and live in different countries all around the world - With stronger foreign ties come a different, new perspective on all aspects of life and business which I continue to embrace.
Apart from my travels, I’m a privacy advocate and supporter of technologies and ideas that help promote personal freedom, decentralize certain aspects of power, and are easily accessible to everyone - now or in the near future.
Whenever I’m not working, I like to disconnect and return a different era - with crackling vinyls, glowing amplifiers and tennis.
