The purpose of Scale-up Denmark is to create more growth companies by strengthening regional specialisation within the business sector, so that the regions’ strength positions are supported. The initiative is inspired by Team Denmark’s work to develop top-patlets by training the best intensively, so that some of them become tupatlers. In the same way, Scale-up Denmark is about the best potential growth companies taking part in a training programme where they are trained to become the elite of the future within their area. Here is the plan for 57 companies to participate in the programme in Region Sjælland. The expected effect of Scale-up Denmark in Region Zealand is that the participating potential growth companies will all continue to achieve an annual growth rate of 20 % after the project period has ended. This is achieved through interregional action, in which two acceleration environments are established in the region. In the first year of the project period, an acceleration environment is established within bio-economy and industrial symbiosis. Next, it is expected that an additional environment will be established in the year 2 of the project period in either smart energy, logistics and transport or the construction industry. Initially, the operator recruits and selects potential growth companies both nationally and internationally. This broad recruitment effort is important to ensure that the best companies with the highest growth potential are identified and activated. The training programmes are targeted at the individual company’s needs to ensure that they get the most out of the training. Then the operator and the company identify how best to organise a training programme for them so that they can scale up the company. Relevant activities in the training programme may include the purchase of external advice, assistance in obtaining external financing, involvement of existing companies or maturation for exit. Involvement of existing companies is central here, as the success of Scale-up Denmark depends to a large extent on how well the ecosystem is activated. In addition, during the training programme, a growth plan is drawn up that maps out how the company is to be scaled up after the training has ended. It also identifies how the scale-up is expected to be reflected in turnover, job creation and exports. It is also fundamental in Scale-up Denmark that it is a sustainable initiative, which is why the focus is on the establishment of a sustainable business model that will continue even after the project period expires.
