We are Lemon.

Mobility continues to grow at an astonishing rate.
So why should knowledge transfer be static?

We believe that life-long learning, accessing information and education should never be a burden, but an opportunity. To make learning an easy, enjoyable process, we develop advanced, innovative mobile knowledge solutions that are fun to work with and make it a pleasure to collaborate, to communicate and share the joy of being empowered with knowledge.

Our vision:
efficient transfer of know-how
with mobile devices.

The mobile use of corporate know-how makes it easy to deliver and access knowledge: the content comes to the user, and not the other way round. We are fascinated by two aspects: the easy delivery of knowledge through touchpoints that can be used completely independently of location or time, and the wide range of extensions that can be added on to meet individual customer wishes. We believe that the future of knowledge transfer and learning is mobile, and our vision is to actively shape and develop this trend.
