TAM SAM SOM tips for Indian founders
Bottom-up beats top-down
Indian VCs like Sequoia India and Accel always prefer bottom-up market sizing. Start with number of customers × price. Top-down is a cross-check, not the primary method.
SAM > ₹500 Cr minimum
For Indian seed VCs, SAM below ₹500 Cr raises questions about fund return potential. For Series A, SAM should be ₹2,000 Cr+. TAM should be 10–100x larger than SAM.
SOM must be credible
SOM of >5% of SAM in Year 3 looks unrealistic to most investors. Your SOM should tie directly to your sales capacity, GTM budget, and team size — not just a percentage.
Cite Indian-specific data
Quoting "the global market is $1T" for an India-focused startup is a red flag. Use NASSCOM, RBI, DPIIT, or Redseer India-specific data. Indian VCs know these sources intimately.
Market size estimates are based on user inputs and are for educational and pitch preparation purposes only. Always validate with primary research and cite credible sources in investor materials.
