Frequently Asked Questions
What is the difference between TAM, SAM, and SOM?
TAM (Total Addressable Market) is the total market demand for your product or service. SAM (Serviceable Addressable Market) is the portion of TAM you can realistically reach given your geography, channels, and capabilities. SOM (Serviceable Obtainable Market) is the share of SAM you can capture in the near term. We help you define all three with data-backed precision.
How accurate are market sizing estimates?
Accuracy depends on data availability and methodology. We combine primary research (surveys, expert interviews) with secondary data (industry reports, government statistics) and transparently state our assumptions and confidence intervals. Our estimates are grounded in evidence, not guesswork.
How long does a market sizing project typically take?
A standard market sizing project takes 4-6 weeks, depending on the complexity, geographic scope, and availability of secondary data. Rush projects can be completed in 2-3 weeks with expedited data collection.
Can you forecast market size for multiple years?
Yes. We develop multi-year forecasts using trend analysis, growth rate modelling, and scenario planning. Our forecasts incorporate macroeconomic indicators, industry trends, and expert input to provide a robust view of future market evolution.
