Most important: The logo also has to work as an app icon! This means that it has to work on a small space (so lines can't be too thin) and needs to be easily recognizable on a smartphone screen.
This icon is our main face to the customer, so it is important that it is unique and differentiates us from other similar apps.
We would like a clean, compact design which can easily be recognized again. It should look modern and stylish.
We would like to symbolize that either 1) we enable people to organize and plan their need for e-Vans 2) we assist people in bringing large or heavy goods from A to B. It is important that we do NOT include pictures of vans or electric vehicles. The logo should be more abstract.
We want to be friendly but not too childish, we want to be clear but not too technical (heyTobi! is a helpful personal assistant to you).
We would like modern colors, but not neon.
Regarding the writing, we do not want to emphasize the "hey and !" in "heyTobi!" too much, as "Tobi" (your personal assistant) is the most important part. It would be great if this would be visible in the writing.
We are especially interested in logos which are making creative use of negative space.
