Green-Tech expertise in program form: ACCELERATE To the program
>SMART> GREEN Startup Night on 27.09. Register


We founded Grünhof in 2013 to provide a home for creative thinkers, sustainability-oriented innovators and startup enthusiasts. In addition to our mission to support people in the realization of their ideas, we want to create a platform for startup culture and entrepreneurship that is played host to by many different actors. To make this possible, we work one thing above all: together! We are not only concerned with the "what", but also with the "how": Both within the Grünhof community and with external players, we want to shape a new culture of cooperation. Transparent and honest dealings with each other are just as much a part of our principles as a constructive and optimistic view of the future. Because one thing is certain: together we can move a lot!

KREATIVPARK LOKHALLE: Our container village

On June 1, 2018, we opened another Grünhof location: The startup and innovation center Kreativpark Lokhalle. In the future, the new location will be the center for companies, startups and creative minds in the Freiburg area. With the community idea behind this project, a place is to be created where knowledge, know-how and ideas are shared and advanced. In addition, the >SMART> GREEN Startups get a new home here: Here you work in an indoor container village on 1.600m² in teamspaces and coworking desks or have a creative session in our popup teamspace.

If that’s not startup enough for you, you can also just lie down in the hammock with your MacBook or chat with the developer or graphic designer next door in our café bar. After all, we want the Kreativpark Lokhalle to be a lively and colorful community where people can exchange ideas and work together. Our community manager will make sure that you become part of our network as quickly as possible!
