Lena Jüngst Lena is the Co-Founder & Chief Evangelist of the start-up @airup . Lena, along with classmate and co-founder Tim Jäger, developed the world’s first drinking bottle system that flavors water by scent during her design studies. Her goal is to reduce the excessive consumption of sugar in the form of soft drinks and to save plastic and CO2. By turning down a high-class job as a product designer at Philips, she decided to instead focus entirely on developing her own idea. By not ruling anything out from the start and allowing freedom of thought, she’s turned her personal beliefs into her own dream job.
