Impact Hub
Hamburg Candidate

Impact Hub is a global community of people who create positive change, challenge the status quo and reimagine the future. After some challenging and turbulent months, Impact Hub Hamburg is now part of 105 VIERTEL.
Together we will continue the mission:
pushing for sustainable and inclusive innovation at scale.

For more information on the recent developments, please see the LinkedIn post, press release, or our FAQ. In November we officially received Impact Hub Hamburg Candidate status and are in the process of reactivating the old channels (Website, LinkedIn, Instagram). Stay tuned!

Putting your idea and yourself out there is less intimidating when you have a community of like-minded people behind you. In this spirit, we invite all former Impact Hub Hamburg members to rejoin our community and everyone else to become a part of an exciting network! We offer knowledge sharing, peer support, access to experts, and events that inspire. Getting to know new perspectives and receiving feedback from a multitude of people is a huge source of inspiration and creativity that we want to tap into with you.

Further Offerings

Our office at Gänsemarkt 33 has a free open desk area where we offer coworking. As a member, you have the option to book a desk through your membership page and to check availability if you want to join spontaneously. Moreover, we have one conference room and a large kitchen that is a great basis for an open exchange. For larger gatherings, 105 VIERTEL owns the venues Grüner Jäger in St. Pauli and Phoenix in Phoenixhöfe in Altona where we are sure we will have the occasional amazing parties. Let us grow together and make the best use of the space!

Given the background of the people at 105 VIERTEL, we want to help our members grow and accelerate their impact. We launched our 105 VIERTEL Impact Accelerator in September: Eight exciting circularity startups are currently working on reaching their next growth goals through business und impact mentorship.
