Market Sizing and ForecastingMarket sizing you can show your workings for
TAM, SAM and SOM built from a documented model, sized by segment and geography, with scenario forecasts that show what has to be true for each number to hold.
Is this for you?
- You are preparing an investment case, business plan or investor deck and need a defensible market size.
- Your current sizing is a single top-down number with no segment detail.
- You need to know which segments or geographies drive growth, not just the headline figure.
- A lender, investor or board has asked how the number was arrived at.
What you get
- 01
TAM, SAM, SOM

How we work
- Step 01
Define
Market boundaries, segments, time horizon and the decision the number feeds.
- Step 02
Build
Bottom-up (units × price, installed base, consumption) and top-down (macro and proxy) models.
- Step 03
Reconcile and test
The two approaches are reconciled; gaps are closed with targeted interviews or trade data.
- Step 04
Deliver
Model, memo and a walkthrough of the sensitivities.
Why IMR for this
Two independent methods reconciled, so the number is not resting on one assumption.
The model is yours: editable, documented, and reusable for the next planning cycle.
Experience sizing industrial, chemical, agricultural and consumer markets across India, the Middle East, Europe and North America.
Frequently asked questions
Do you use published data or your own?
Both. Published sources are triangulated against trade data, company disclosures and, where needed, primary interviews.
How far out can you forecast?
Typically 5–10 years, with scenarios. Longer horizons are expressed as ranges, not points.
Will investors accept the methodology?
The memo is written for investor and lender review and states every assumption so it can be challenged.
