Indian businesses entering new markets, raising equity rounds, or expanding product lines face a fundamental challenge: they cannot convincingly articulate the size of their opportunity to investors, board members, or strategic partners. A Market Sizing Study using TAM, SAM, and SOM methodology provides data-backed credibility that transforms a business pitch from aspiration to institutional-grade opportunity analysis. Under the SEBI (Issue of Capital and Disclosure Requirements) Regulations 2018, listed companies undertaking preferential allotments or Rights Issues must disclose market position and competitors in the offer document, making structured market sizing not merely strategic but increasingly a compliance-adjacent necessity. The Companies Act 2013 (Section 134) mandates board reports to include business segment analysis, and bank lending assessments under RBI guidelines increasingly weight market positioning data. KAMRIT Financial Services LLP delivers end-to-end market sizing engagements: from primary research and secondary data synthesis to stakeholder interviews and structured TAM-SAM-SOM modeling, producing reports that satisfy investor due diligence, internal board presentations, and strategic planning cycles. Our studies have supported fundraise documentation for companies across fintech, agritech, healthcare technology, and D2C consumer brands.
What is Market Sizing Study (TAM, SAM, SOM) in India 2026?
A Market Sizing Study is a structured quantitative and qualitative assessment of the commercial opportunity available to a business, broken into three hierarchical layers. TAM (Total Addressable Market) represents the gross revenue potential if a company captured 100% of its defined market category without any constraints. SAM (Serviceable Addressable Market) narrows this to the geographic and regulatory jurisdictions where the company can realistically operate, accounting for distribution reach, import restrictions, or state-level licensing requirements under central acts such as the Drugs and Cosmetics Act 1940 or the Motor Vehicles Act 1988. SOM (Serviceable Obtainable Market) projects the realistic market share capture based on current competitive positioning, sales capacity, and channel penetration. This methodology originated with US investment banking but has become standard in Indian startup ecosystems, particularly for companies preparing Information Memorandums under SEBI (ICDR) Schedule XVI for qualified institutional placements or preferential issuances under Section 62 of the Companies Act 2013. The study applies to consumer goods companies assessing FMCG distribution zones, technology firms quantifying India's SaaS addressable base under the DPIIT Startup India framework, and manufacturing businesses evaluating PLI (Production Linked Incentive) scheme eligible categories under the Ministry of Commerce and Industry.
Who needs this
Market Sizing Studies are commissioned by businesses that require validated opportunity quantification for external or internal stakeholders. The following conditions typically trigger or enhance the value of a formal study.
- Companies preparing for Series A through Series D equity fundraising where investors require independent market validation as part of term sheet due diligence
- Listed entities undertaking Qualified Institutional Placement (QIP) or preferential allotment under SEBI (ICDR) Regulations 2018 requiring offer document disclosures
- Startups registered under DPIIT Startup India seeking tax benefits under Section 80-IAC of the Income Tax Act 1961 where market size is a board reporting requirement
- FMCG or consumer goods companies entering new state markets requiring distributor network sizing and retail outlet mapping per BIS standards
- Healthcare and pharmaceutical companies entering new drug categories where market sizing supports pricing strategy under the Drugs (Prices Control) Order 2013
- Manufacturing firms evaluating PLI Scheme eligibility requiring proof of market size for eligible product categories notified by the Ministry of Commerce
- NBFCs and fintech companies assessing loan book potential where market sizing supports RBI registration applications or scale-up approvals
- Real estate developers and property technology firms where RERA registration under Section 3 of RERA Act 2016 requires project market viability disclosures
- Agritech companies seeking VC funding where TAM-SAM-SOM framing is a standard expectation of seed and growth-stage investors
- Export-oriented companies quantifying overseas market segments to support Export-Import Bank (EXIM Bank) credit applications
Documents required
KAMRIT requires a structured data package from the client to initiate a market sizing engagement. The completeness of inputs directly determines the accuracy and defensibility of outputs.
- Company Registration Certificate (INC-7 or INC-20 for companies registered post-2013 via MCA21 SPICe+ portal) and CIN confirmation
- Latest Audited Financial Statements for three financial years with revenue segmentation by product line or geography
- Current Product or Service Portfolio with MSIC codes (Ministry of Statistics and Programme Implementation classification) for industry mapping
- Existing Customer Database or Contract List (minimum 20 reference customers for B2B studies) with annual contract values
- Competitor Matrix listing direct competitors with estimated market share data from annual reports or Tracxn/Crunchbase sources
- Distribution Channel Map showing existing dealer, distributor, or retail outlet coverage by PIN code or state
- Board Resolution authorizing the engagement of external market research consultant (required for listed companies under SEBI LODR)
- Founder or Management Team CVs with industry tenure documentation to establish domain expertise claims in the study narrative
- Previous Market Research Reports if any third-party studies exist (BIS, Euromonitor, Inc42 DataLabs, Redseer) for triangulation
- Technology Stack or IP Documentation for software or deep-tech companies where market definitions are based on adoption curves
- Regulatory Licenses or Registrations currently held (FSSAI license numbers, RBI registration, ISO certifications) to establish compliance baseline
How KAMRIT runs it, step by step
KAMRIT executes market sizing engagements through a five-stage methodology that combines bottom-up primary research with top-down secondary data analysis.
- Discovery and Scope Definition. KAMRIT conducts a 90-minute discovery session with founders or business heads to define market boundaries, geographic scope, customer segment universe, and competitive perimeter. This session produces a signed Project Initiation Document (PID) specifying TAM definition, SAM constraints, SOM time horizon (Year 1-3), and deliverable format. The engagement formally commences upon PID sign-off. This stage is completed within 3 working days of data package receipt.
- Secondary Research and Data Compilation. Our research team aggregates government statistics (MOSPI reports, DPIIT annual publications, RBI bulletins), industry association data (FICCI, CII, AIOCD for pharma), third-party market research databases (Statista India, Mordor Intelligence, IDC India), and published annual reports of listed competitors. Data is organized by NAICS/MOSIC code clusters and cross-referenced against three independent sources. This stage runs 10 to 15 working days depending on market category depth.
- Primary Research Execution. KAMRIT conducts structured interviews with 15 to 30 industry stakeholders including distributors, channel partners, procurement heads at target customer firms, and retired industry executives. Interviews follow a standardized questionnaire aligned to TAM-SAM-SOM methodology and are conducted under non-disclosure agreements. Survey responses are aggregated and statistically validated. This stage spans 15 to 20 working days.
- TAM-SAM-SOM Modeling and Scenario Analysis. The research team builds three financial models: a bottom-up model deriving SAM from distributor unit economics and retail outlet density, a top-down model triangulating from industry category totals, and a hybrid model for software or subscription businesses based on addressable account count and average contract value. Conservative, base, and aggressive scenarios are produced with explicit assumptions documented for investor scrutiny. This stage requires 7 to 10 working days.
- Report Production, Quality Review, and Delivery. KAMRIT produces a final report including executive summary, market definition methodology, primary research findings, TAM-SAM-SOM tables with confidence intervals, competitor landscape with estimated share percentages, and strategic implications narrative. The report undergoes internal quality review for data sourcing verification and assumption transparency. A PDF report and editable Excel model are delivered via secure sharing. Final delivery occurs within 5 working days of model completion. Total engagement duration: 40 to 60 working days from kickoff.
Timeline
A standard market sizing engagement spans 40 to 60 working days from the date KAMRIT receives a complete data package and Project Initiation Document sign-off. The discovery and scope definition stage (3 working days) is entirely within KAMRIT's control and experiences minimal delays provided the client attends the kickoff session. Secondary research compilation (10 to 15 working days) is subject to data availability; markets with limited published reports from MOSPI or industry associations may require extended research periods. Primary research execution (15 to 20 working days) is the most variable stage, as respondent availability for industry interviews can extend timelines by 5 to 10 days during festival periods or year-end closures. KAMRIT factors in a 10% time buffer in the project schedule. The modeling and report production stage (12 to 15 working days) is within KAMRIT's control pending data validation completion. For companies preparing for time-bound fundraising closes or board meetings, KAMRIT offers an expedited 25-working-day engagement with adjusted scope (TAM-SAM only, 10 stakeholder interviews) at a premium fee structure.
How our pricing compares
KAMRIT Financial Services LLP prices the TAM-SAM-SOM Market Sizing Study engagement at a starting rate of ₹84,899 for standard scope (40 to 60 working days, 20 to 30 stakeholder interviews, all three model scenarios). By comparison, premium global research providers such as Gartner India charge ₹3,50,000 to ₹12,00,000 for comparable technology sector studies with extended analyst time. Indian-specialist firms including Redseer and Ken Research price market sizing deliverables between ₹1,50,000 and ₹4,50,000 depending on market complexity and data exclusivity. Tracxn Data offers off-the-shelf sector reports from ₹25,000 but these are generic compilations without primary research or customized SOM modeling. Inc42 DataLabs charges ₹40,000 to ₹80,000 for startup ecosystem TAM assessments but their coverage is limited to technology and new economy categories. KAMRIT's pricing is positioned between off-the-shelf data reports and full-service premium consultancies, offering primary research customization and TAM-SAM-SOM methodology at approximately 40% to 60% below specialist Indian market research firms. Government fees are not applicable as this is a private advisory engagement. The fee includes one revision cycle for executive summary adjustments. Additional stakeholder interviews beyond 30 are billed at ₹4,500 per interview. Expedited delivery (25 working days) carries a 35% premium.
Common mistakes KAMRIT avoids
Indian businesses commissioning market sizing studies frequently make errors that undermine the credibility of the output or result in unusable deliverables for investor or board purposes.
- Defining TAM too broadly to inflate the headline number without SAM constraints, which sophisticated investors immediately reject during due diligence questioning
- Relying exclusively on secondary data without primary stakeholder interviews, leading to findings that are publicly available and carry no independent validation premium
- Failing to segment competitors correctly by geography or customer type, causing SAM calculations to include categories where regulatory entry is restricted (e.g., pharmaceutical segments requiring specific manufacturing licenses under Schedule M of Drugs and Cosmetics Rules 1945)
- Using outdated pricing assumptions from pre-GST data, causing revenue-per-unit calculations to overstate market opportunity since the GST Council reforms restructured channel margins across FMCG, electronics, and automotive categories
- Neglecting to map distribution infrastructure constraints in SAM calculations, particularly for companies expanding into rural markets where the National Rural Roads Development Mission logistics corridors affect realistic reach
- Presenting SOM projections without explicit assumptions on customer acquisition cost and conversion rates, making the obtainable market figure unverifiable for investors
- Commissioning studies without aligning methodology to investor expectations, particularly for VC presentations where SOM must demonstrate achievable milestone funding requirements (e.g., ₹X Crore revenue requiring Y% market share of SOM)
