A growing number of studies in the international entrepreneurship field have been devoted to born global companies (BG) and international new ventures (INV), covering such problems as their founding processes, organization, strategy and performance, their environments of activity (Aspelund, Madsen, & Moen, 2007), reinternationalization and deinternationalization processes (Trąpczyński, 2015; Zhang & Larimo, 2011), motives of founding and key success factors (Kowalik & Baranowska-Prokop, 2013; Hollensen, 2011; Karra & Philips, 2004), decision-making styles (Francioni, Musso, & Cioppi, 2015), networking activities (Sepulveda & Gabrielsson, 2013), learning orientation, and other strategic orientations of such firms (Pellegrino & McNaughton, 2015; Eggers, Kraus, Hughes, Laraway, & Snycerski, 2013). There are still few studies, however, regarding the marketing activity of these companies. So far, their managerial competencies, the communication and marketing channels they use, and their approach to customers have not been adequately explored. Furthermore, as emphasized in the literature, the contribution of marketing to accelerated internationalization needs to be studied through empirical projects (Gabrielsson & Kirpalani, 2012; A. Rialp, J. Rialp, & Knight, 2015; Knight & Liesch, 2016; Hagen & Zucchella, 2018). Current research also shows that these problems are relevant for SMEs originating in the Central and Eastern European Countries (CEECs; Nowiński & Rialp, 2013; Wach, 2017; Kowalik, Danik, & Sikora, 2017). The share of quickly internationalizing small and medium-sized enterprises in Polish foreign trade has been growing, and their role in Polish economic growth is vital (Wach & Maciejewski, 2019). These SMEs are responsible for almost one-third of Polish foreign trade—they contribute to 30% of Polish export value and to 37% of import value (World Trade Organization, 2016), as well as represent the highest export dynamics among Polish firms. Just in the years between 2007 and 2014, their exports doubled (PARP, 2017). Listed among the important entrepreneurship growth determinants in Poland, the Global Entrepreneurship Monitor report includes the increasing availability of different forms of financing, the dynamic and open internal market, and growing access to telecommunications infrastructure (PARP, 2018). To describe the early internationalized firms, various terms have been used, such as: born globals (Rennie, 1993; Knight & Cavusgil, 1996; Moen & Servais, 2002); international new ventures (McDougall, Shane, & Oviatt, 1994; Crick, 2009); born internationals (Kundu & Katz, 2003); born exporters (Quelch & Klein, 1996); and early internationalizing firms (Rialp et al., 2005). Moreover, the definitions and classification criteria used in this field are not uniform (Madsen, 2013). Oviatt and McDougall (1994) define an international new venture as “a business organization that, from inception, seeks to derive significant competitive advantage from the use of resources and the sale of outputs in multiple countries,” while other authors concentrate on the indicators
