Act as a market analyst. For my project [PROJECT_NAME] in the [INDUSTRY] sector and located in [COUNTRY_REGION], perform an estimation of TAM (Total Addressable Market), SAM (Serviceable Available Market), and SOM (Serviceable Obtainable Market). Use a top-down approach (based on macroeconomic data) and a bottom-up approach (based on the estimated number of potential customers and average price). For TAM, take into account the relevant global or national market. For SAM, restrict to the segment we can reach with our current offering. For SOM, estimate a realistic share over 3 years based on our commercial capacity. Provide the figures in euros or dollars, with clear sources or assumptions.
