The main goal of this academic investigation is to improve theoretical and practical understanding of the startup industry. This includes a thorough analysis of the essential elements and drivers that support the development of a healthy ecosystem. A thorough examination of numerous models' representative of startup ecosystems, including the 3M model, improved from the previous 5M framework, is at the heart of this endeavour. This model is the focus of the analysis because of its extreme importance. The inquiry also looks at how it might be used in Algeria, where the model's components are sharply projected onto the local topography. An extremely thorough examination follows, with a special emphasis on Executive Decree No. 20/254, a piece of legislation outlining the boundaries of startups and their legal requirements. This thorough evaluation helps us understand the complex interactions between conceptual frameworks, legal definitions, and practical implementation.
