Scenarios

Saying "the market is huge" is not a strategy.

Build your TAM, SAM, and SOM with assumptions you can defend line by line. For founders, operators, and strategy teams who get questioned on the numbers.

Audience

Who this is for

For anyone presenting a market-entry decision to people who will question every assumption — boards, investors, partnership committees, internal strategy reviews.

Startup founders & CEOs
Early-stage teams
SMBs entering new markets
Strategy consultants
CMOs evaluating segments
Founders building pitch decks
The problem

Why most market sizing models fail

Most templates give you a number for slide 7 of the deck. They don't give you the logic. So when an investor asks how you got to ₹2,400 Cr, you don't have an answer.

  • Top-down only, no bottom-up sanity check
  • TAM inflated because segmentation isn't built in
  • Pricing not connected to the revenue model
  • No scenarios, no stress test
  • Penetration rate pulled from thin air

Differentiation

Why this is different

Most templates give you the number. This one gives you the logic — sheet by sheet, assumption by assumption — so anyone reading the model can trace how every figure was built.

Most templates
  • Top-down assumptions, no detail
  • TAM overstated, no segmentation
  • Capture rates aspirational
  • Pricing disconnected from revenue
  • No strategic context
This toolkit
  • Segmentation logic at every level
  • Pricing tied directly to SOM
  • Explicit customer base assumptions
  • Penetration from comparable benchmarks
  • Output framed for boards and investors

Outcomes

What you walk away with

01
Numbers you can defend
Every figure traces back to a stated assumption. When an investor pushes back, you don't guess — you point to the cell.
02
Output that drops into decks
Summary tables and charts come pre-formatted for pitch and board decks. Copy, paste, ship. No rebuilding from scratch.
03
Three scenarios, stress-tested
Conservative, realistic, aggressive — modeled on the same logic, with sensitivity tables across pricing and volume.
Common questions

Frequently asked

What files are in the download?
Three files. The main 12-sheet Excel TAM-SAM-SOM model with 316 formulas. A separate stress-testing workbook. A filled example version with realistic data. Plus a blank master template and an instruction sheet. All editable.
Does this work for any industry or market?
Yes. The structure is industry-agnostic — you input your own segmentation, pricing, and customer assumptions. Used across SaaS, D2C, B2B services, ecommerce, healthcare, and education.
Can I use this for an investor pitch deck?
Yes. The output pages generate summary tables and charts that map directly onto pitch deck slides. The model forces the segmentation, penetration, and bottom-up logic investors ask about during due diligence.
What's the difference between the main model and the stress-testing variant?
The main model builds your TAM-SAM-SOM bottom-up from your inputs. The stress-testing variant takes the same logic and runs bull, base, and bear cases across pricing and volume. Both files are included.
