About Lilium

About us Lilium is a disruptive aviation start-up based in Munich. Co-founded in 2015 by Daniel Wiegand, Sebastian Born, Patrick Nathen and Matthias Meiner, the team brings together international world-class engineers and designers. The group shares the vision of a completely new type of individual transportation and is dedicated to develop and build the world’s first fully electric vertical take-off and landing (VTOL) jet. An estimated range of up to 300 km and a top speed of 300 km/h, along with zero emissions make it the most efficient and eco-friendly individual means of transportation of our time. By providing ultra-redundancy, the Lilium Jet will also set new standards in safety. Lilium aims at liberating towns and cities from today’s congestion and pollution, with people able to come and go freely, vastly expanding the radius of their everyday lives.
