Grow together.

We want to make people independent. And give them absolute freedom of knowledge.

Lifelong learning, informing and educating should not be a constraint, but an opportunity. To make working with learning content as easy and enjoyable as possible, we develop advanced and innovative e-learning environments that are fun to use. And which also make it easier for people to exchange ideas, communicate and participate in the common progress of knowledge.

The two founders and managing partners of Lemon Systems GmbH, Kay Mathiesen and Björn Carstensen.

Our vision: efficient know-how transfer via mobile devices.

The mobile use of corporate know-how makes information procurement easy: the content comes to the user and no longer the other way around. We are fascinated by 2 things: the simple provision of knowledge via touchpoints that can be used absolutely independent of location and time, on the one hand, and the diverse extension options to serve individual customer requirements, on the other. We believe that the future of knowledge transfer and learning is mobile. With our team of 15 employees, we want to actively help shape and develop this development.
