“Actually it's always not good to know the future because then all of a sudden you tell if I had known that this takes 10 years to become successful I may have done something differently. So sometimes it's good also not to know that it will become difficult. Um, but what I would have done differently I think we would have been more thoughtful on selecting our first investors because at the beginning beggars can't be choosers so we picked any kind of investor we could find but at a certain level It's very helpful if you have well-connected investors. And so that's definitely something I would do differently today.”
