Centr is a collective of ambitious students realising their entrepreneurial ambitions by means of launching startups together. The concept is based on the idea that successful businesses result from a great team and ideas are of secondary importance. We take a problem-based approach, in which special attention is given to quickly validating a market need to avoid spending time on an unwanted product. In addition to checking desirability, we strive to verify viability and feasibility as soon as possible, as to minimize the risk of failure later in the process.
