We are no VC.
For us VC means Value Creation.
Our core belief is that with a "Mittelstands-DNA" focusing on sustainable growth we can create the best value for our founders.
We are not going to Mars.
reziprok invests in founders and funds focusing on products which solve real-world problems.
We are no consultancy.
Founders are at the heart of everything we do. From seed or series X, we take care, personally and hands-on: networks, capital, clients, distribution channels, advice, coaching, industry expertise - you name it.
Ask our founders, they love us.

"Working with reziprok is, in my experience, very straightforward. They are keen to understand the business and continuously offer a variety of suggestions for improvements, support, or new angles - always with sensibility, trust, and the recognition that the real expertise sits within the business itself. The dialogue is direct and non-bureaucratic, and there is a clear structure that drives the business forward. Strong support for entrepreneur-led companies."
