B-VIP is incentives based, as it rewards you for your dedication and hard work. The more milestones you achieve, the more services you unlock. The program will help you validate some of your assumptions, as well as help you to identify and jettison those that are not relevant and/or no longer valid. In the end you would have transformed your idea to create a minimum viable product (MVP), along with one or more business models that will set you up for establishing a commercially viable business entity.
There is no country limit. There is no expertise limit. You just need an internet connection to apply.
