To size the market for your tech business, define your target audience (industry, size, region). Estimate the Total Addressable Market (TAM), the entire market demand for your solution. Narrow to Serviceable Available Market (SAM), the portion you can realistically target. Focus on Serviceable Obtainable Market (SOM), the market share you can capture in the short term. Use industry data, competitor insights, and customer trends to refine estimates for growth planning.
