Founder Noemi Dulischewski is aiming to raise £10,000 by 17 November to launch the project in The Taproom at London Fields Brewery.
Since 2015 brünch has run events with partners including London Union, German Gymnasium and Jamie Oliver’s Big Feastival.
Now the pop-up is ready to go permanent, with the aim of ‘bringing people together for 'long, lazy Berlin-style brunches’.
In a video on the Kickstarter page, Dulischewski said she wanted the café to ‘bring The Taproom back in to the heart of the London Fields community’.
A former Berliner, Dulischewski left her corporate job in London to launch brünch two years ago.
The pop-up serves platters of cold cuts and cheeses, homemade granola, buckwheat waffles, and traditional German desserts laid out on a table.
The Taproom is being redesigned for the cafe's launch to create a 'lighter and airier' space.
Dulischewski said it was her 'ambitious' aim to open the café in less than a month’s time.
