A proof of concept represents evidence of the reasonable feasibility of a concept. Only when the basis for verification has been created can a business model or a product be pronounced commercially viable. Whoever thus proves the economic chances of his ideas through the PoC test gains knowledge about the performance of his idea on the market. In doing so, he does not take the risk of sending the new development into the race without securing it. This saves unassessed losses for the company. If a PoC is meaningful, it offers the best prerequisites for getting investors excited about the idea.
