For years, HiveBuzz has operated with the sole source of funding being the income from the few posts published. It simply doesn't work to support such a project (infrastructure, developers and other people working with us).
We don't have a "business model" as you suggest because we don't sell services. The purpose of our activity is to motivate and promote user retention on the platform. If the amount of the proposal may seem high, it must be taken into consideration that it is spread over two years.
