The thesis titled "The Creation, Growth, and Development of a Startup Company on the Example of Hivetech" deals with the key aspects of founding and developing a startup company, with a focus on the example of Hivetech, an independent digital agency from Croatia. The author examines the specific challenges, opportunities, and strategies related to startups, with the aim of identifying success factors and risks, all supported by the example of the successful startup company HIVETECH. The work begins with an introduction to the concept of a startup, defined as a company in its early stages of development, with high innovation potential but also increased risks. Startups typically face challenges such as lack of resources, need for funding, and market uncertainty. Special attention is given to the differences between startups and traditional companies, with startups standing out for their adaptability and innovation. The author thoroughly analyzes startup creation models, including various business models such as B2B (business-to-business) and SaaS (software as a service). The social significance of entrepreneurship is also addressed, where startups are described as key drivers of economic development and innovation. The paper discusses the advantages as well as the challenges faced by startups, including financial obstacles, bureaucratic challenges, and the importance of an agile business model. Hivetech is presented as an example of a successful Croatian startup, which, through innovative technological solutions such as the application of artificial intelligence and cybersecurity, has managed to expand its operations to the international market, with a special focus on its branch in Dubai. The key success factors of Hivetech include technological excellence, adaptability to market changes, a skilled team, and a focus on customer experience. Additionally, Hivetech continuously invests in the development of its employees and technical capabilities, allowing it to remain competitive and sustain growth. The research methodology is based on both primary and secondary data analysis, including interviews conducted with key figures at Hivetech. The data analysis provides insight into key trends in business and technologies that Hivetech uses to improve its services. In conclusion, the paper provides an overview of the key factors for startup success, emphasizing the importance of innovation, agility, and market adaptability. It also highlights the importance of quality management and constant investment in employee development as crucial elements for the long-term success of a company. The paper also offers suggestions for further research in this area, including possibilities for the development of Hivetech and other startups in similar industries.
