Start-up companies are increasingly growing by exploiting disruptive ideas and recent digital technologies. As of November 2018, there are about 9,000 innovative start-ups in Italy, leading the employment rate to grow up above 5% per semester, with about 40,000 shareholders and over 12,000 employees (Sole 24 Ore, 2018).
Many scholars investigated the growing phenomenon of start-ups in last decade (Petretto, 2009; Blank, 2013; Cohen et al., 2019) highlighting the most relevant features as the drivers of success (Scagnelli et al., 2018), the control systems (Samagaio et al., 2018) and the role of actors in shaping the start-up ecosystem (Sipola et al., 2016).

Most of studies indeed focus on the relationship between universities and young companies in term of spin-offs, education/training activities and technology transfer (Shane, 2003, Petretto, 2009; Dempwolf et al., 2014). Due to the novelty of these supports,
