SMEs are the backbone of the Austrian economy, and most startups are SMEs. The European Commission strives to support SMEs to establish and do business cross-borders since it generates a direct impact on the GDP, value chain, and economic growth. Likewise, important Austrian players in the business ecosystem, such as the Science Park Graz, endeavor with the shared goal of supporting the national companies to grow and thrive. However, the SPG does not have a defined model for supporting the incubated startups to grow into foreign markets, which justifies this master’s thesis objective: to develop a model for a high-technology incubator company to adopt and provide consulting services to startups aiming to do business abroad. First, is executed intense theoretical research to obtain a literature basis and to de-velop a theoretical service design model based on the key factors raised. Second, the theoretical model proposed and the key factors found are utilized as guides to the practical research, in which 14 semi-structured individual interviews were real-ised. The information requirement was to analyse the needs of Austrian startups growing cross-borders that could be addressed by the SPG’s service model, and this outcome is reached through the qualitative research, in addition to understand-ing the services provided by each one of the four main institutions in Austrian eco-system, along the international market development process studied. In conclusion, the service design model proposed is appropriate and covers the main facts that emerged from literature research and the needs of startups inter-viewed. Moreover, it is emphasised the proposal that SPG should be positioning itself as the expert in startups development, supporting the incubated startups to find and validate product-market fit into foreign markets. Besides this, it is recom-mended to invest in the internal and external network, to be able to provide services related to Legal, Talent hiring, and lessons learned from Austrian startups doing business abroad.
