Do I have to work absolutely on brief?

One of the things that make jovoto so special is the fact that you have more freedom in developing your idea - this is not agency work!
With jovoto you can try things out, experiment with ideas, and let your creativity run wild. Of course, this doesn’t mean that the briefing is irrelevant. We will always advise you to take the briefing into consideration carefully. But you should also feel free to surprise us and the client if you have a brilliant idea.
We discussed the matter in this blog post.
