circle17, an initiative by AustrianStartups and respACT, explores the opportunities that arise from the collaboration of companies (= Challenge Leads) with start-ups and individuals in the field of the Sustainable Development Goals with a focus on circular economy. A pool of talents (graduates, young individuals who are interested in working within the sustainability sector, etc.) will be introduced to the companies. The Impacthon is seen as an opportunity to recruit future employees and to develop sustainable business models together. In addition, the companies will be connected with Startups from the sustainability sector during the matchmaking event in order to create potential cooperations.
