Food Tech Market Sizing: Estimating TAM, SAM and a Product's Reachable Customers

Walk through how you would estimate three nested market sizes for the food tech industry: - **Total available market (TAM):** all the spending the industry could address. - **Serviceable available market (SAM):** the part of that market a product like ours can actually serve. - **Target market:** the customers who would actually use our product. Explain how you would structure each calculation, which assumptions you would make and how you would check the result. Give rough figures under the assumptions you state. ```hint Narrow in steps "Food tech" covers very different businesses. Fix the scope, the unit of measure and what "our product" is before calculating anything, then make each market a filtered slice of the one above it. ``` ### Clarifying Questions - Which businesses count as food tech here: consumer ordering and delivery, online grocery, meal kits, smart kitchen devices, software sold to restaurants, or new ways of producing food? - Which geography and period: one country or the whole world, and yearly spend today or a projection a few years out? - What is "our product"? The target market depends on whether we are a delivery app, a grocery service or something else, and on whether we are a new entrant or an established player. - Should the markets be measured as the consumer spend flowing through these products, or as the revenue the companies keep? ### What a Strong Answer Covers - Clear definitions of the three markets and an explicit scope (segments, geography, period, unit) before any arithmetic. - An equation for each market in which every step narrows the previous one, with each input labeled as an assumption and kept to round numbers. - Correct arithmetic, with double counting avoided where segments overlap. - At least one cross-check (a second method or a per-customer plausibility test) and a view of how sensitive the result is to the least certain inputs. - How the three numbers would feed a product or investment decision. ### Follow-up Questions - If the interviewer adds smart kitchen appliances to the scope, how does the estimate change, and which new inputs would you need? - Which single assumption moves your target market the most, and how would you validate it with real data before a launch decision? - How would you size the same three markets for a country where you have very little data?
