I. Introduction
Every year, a massive number of businesses are launched all over the globe with the ambition of becoming successful entities that would remain sustainable in the long run. Most start-ups fail within the first years of existence [1], [2], but the rest of them grow rapidly and contribute to job creation, innovation, and economic growth [3], [4]. Young firms, which are between two and ten years of age [3], [5], [6], face specific challenges related to gaining legitimacy, stability in resource acquisition, and operational efficiency [7]. A critical factor in the success of young firms is the ability of their founders to meet new challenges as the company evolves through the various stages of the business development process [8], [9]. To survive and become more profitable, young entities need to change or improve the initial business model [10]. In addition, today's dynamic and turbulent business environment exerts a direct effect on business models and their innovation [11], [12].
