Launching a product or feature without understanding the market scale is a major risk. Aspiring product managers need a structured way to estimate user demand and market size, even when data is limited. This text-based course equips you with the essential strategic frameworks and mathematical logic needed to size markets confidently. You will transition from guessing to making structured, defensible assumptions that back up your product strategy. What you'll learn: • Understand core market sizing concepts, including TAM, SAM, and SOM. • Apply Fermi estimation techniques to break down complex, ambiguous sizing questions into manageable parts. • Analyze user demand using structured top-down and bottom-up estimation frameworks. • Evaluate market trends and modern data indicators to validate your assumptions. • Formulate clear hypotheses to guide product development and resource allocation. The course begins with foundational definitions of market metrics before guiding you through step-by-step estimation exercises and strategic frameworks.
