The cave of the carp
At Höhle der Karpfen, selected startups from the regional startup ecosystem present their ideas in the competition for the Golden Carp. These startups are specifically nominated by accelerators, high-tech incubators and the Hannover Region startup network. A jury of experts evaluates the participants' innovative approaches and provides valuable feedback. The audience has the opportunity to clap, cheer and stomp loudly for their favorites, making the event a lively and interactive experience.
We will hold the next event in 2025. More information will follow on this page.

On August 13, 2024, the Madsack stage was transformed into a hotspot for innovation and entrepreneurship as part of the Maschseefest. Despite the sweltering 30-degree heat, six promising start-ups presented their business ideas in a rousing one-hour event.
Diverse innovations
The startups' pitches covered a broad spectrum, from technological developments to sustainable business models that address current social challenges. Each of the proposed companies had the chance to convince both the expert jury and the audience of their innovative approaches.
Despite the high temperatures, the atmosphere on and in front of the stage was fantastic. The audience cheered the start-ups on loudly, while the jury listened attentively and evaluated them. The innovative strength and enthusiasm of the founders was clearly noticeable and made the evening an inspiring experience.
The big winner
Alexander Kornelsen and his "Mission to Marsh" project emerged from the competition as the shining winner. He not only secured the prize money of 500 euros, but also the coveted golden carp trophy. Kornelsen's success underlines the growing importance of environmental protection and sustainable solutions in the start-up scene. "Mission to Marsh" is a non-profit company dedicated to the protection and renaturation of marshes. Founded by Alexander Kornelsen and his wife Ann-Christin, the project aims to raise awareness of the ecological importance of marshes and actively contribute to their preservation.
Outlook
The "Höhle der Karpfen" has established itself as an important platform for the region's startup scene. It offers nominated start-ups the opportunity to present their ideas to a broad audience and experts.
The next edition is planned for 2025 and promises to be another highlight for innovators and interested parties. And maybe you'll be there when it's time to raise the curtain on the region's most innovative start-ups!
