This thesis attempts to clarify and define the term « growth hacking » and what it implies in the world of marketing today. It also attempts to present the growth hacking process and mindset as it is used by successful high-tech startups. This thesis then tries to identify what are the keys to successfully implementing growth hacking in any organization, outside of the high tech startup ecosystem, where the movement was born. A qualitative study was conducted interviewing growth hacking experts to provide elements that are part of the growth hacking movement and that can help implement in organizations. Our findings led to defining growth hacking as a new organizational culture that can potentially disrupt traditional marketing by introducing marketing into every aspect of organizations. Growth hacking is also an essential element for healthy competition in industries thanks to its product and customer centricity and low cost and fast implementation with rapid and effective effects on growth.
