Stop guessing your reach and start using a structured engine to project revenue and customer capture based on real geographic and segment filters. ## Overview - **Category:** finance - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_cinYbu6iDTamcOuuFQHZQrel3pRE0ZUljXLkMola/ai-agent-connect - **Tags:** market-sizing, tam-sam-som, business-planning, revenue-projection, strategy ## Description Most founders and strategy leads spend way too much time wrestling with messy spreadsheets to figure out if their business actually has legs. You usually start with a huge number for your total market, but then you have to manually subtract people you can't actually reach or products you aren't actually selling. This Connector handles that math for you. It takes your initial baseline and applies specific filters to narrow it down to your reachable market. From there, it helps you project what you can realistically capture over the next few years. Instead of arguing over "vibes" in a pitch deck, you can show a logical progression from a broad market down to your specific, obtainable target. It’s one of the many tools in the Vinkius catalog that turns abstract business goals into concrete numbers you can actually defend in front of investors or stakeholders. By using both top-down and bottom-up methodologies, you can ensure your projections aren't just optimistic guesses. You can move from a massive global view to a specific regional niche, ensuring that every step of the reduction is based on actual constraints like geography, customer segments, and realistic capture rates. This takes the friction out of market sizing, allowing you to focus on the actual strategy rather than the arithmetic. ## Tools ### apply_sam_refinement Shrinks your total market into a reachable size by applying geographic or segment filters. This helps define your actual reach. ### calculate_tam_base Sets your initial total market size based on your customer base and spending. It establishes the baseline for your calculations. ### project_som_capture Determines your realistic market share and revenue for your obtainable market. Use this to project your 3-year goals. ## Prompt Examples **Prompt:** ``` Calculate my TAM if I have 50,000 potential customers and each spends $100 per year. ``` **Response:** ``` The Total Addressable Market (TAM) is $5,000,000 with 50,000 customers. ``` **Prompt:** ``` My TAM is $10M. If my geographic reach is 30% and my segment target is 50%, what is my SAM? ``` **Response:** ``` Your Serviceable Addressable Market (SAM) is $1,500,000. ``` **Prompt:** ``` If my SAM is $2M and I expect to capture 5% of the market by year 3, what is my SOM? ``` **Response:** ``` Your Serviceable Obtainable Market (SOM) is $100,000. ``` ## Capabilities ### Set a total market baseline Establish the starting point for your total market size using customer counts and spending. ### Narrow market by geography Apply regional filters to see how many customers you can actually reach. ### Filter market by segments Shrink your market size based on specific customer types or product niches. ### Project year 3 capture Calculate your realistic obtainable market share over a multi-year period. ### Calculate reachable revenue Get a clear view of potential revenue based on your specific market filters. ## Use Cases ### Pitch Deck Prep A founder wants to calculate the TAM for a new SaaS product with 50k users at $100 per year. ### Market Entry Analysis A consultant needs to know the SAM for a specific region and product niche to show a client. ### Product Expansion A product manager wants to see the reachable market for a new feature launch in the European market. ### Revenue Forecasting A strategist needs to project what a 5% capture of a $2M SAM looks like by year three. ## Benefits - Get a defensible baseline by using `calculate_tam_base` to turn customer counts into a hard market number. - Stop overestimating your reach by using `apply_sam_refinement` to filter out regions and segments you don't serve. - Defend your 3-year goals with `project_som_capture` to show a realistic path to market share. - Move from subjective guesses to math-based strategy by applying consistent reduction filters to every calculation. - Save hours of manual spreadsheet work by letting your agent handle the multi-step market sizing logic. ## How It Works The bottom line is you get a defensible, multi-layered market sizing model without the manual spreadsheet headaches. 1.

Instead of using vague estimates, you can show investors a logical calculation based on your actual reach and segments. **What is the difference between TAM and SAM in this tool?** TAM is the total potential market. SAM is the portion of that market you can actually reach based on your geography and specific target segments. **Can the TAM-SAM-SOM Calculator handle geographic filters?** Yes, you can use it to shrink your total market into a reachable size by applying specific geographic boundaries. **How do I project my market share with this tool?** You can use the projection tool to determine your realistic capture, which helps you set achievable goals for your business over the next few years. **Is the TAM-SAM-SOM Calculator good for revenue forecasting?** It is excellent for the initial strategy phase. By calculating your obtainable market share, you get a much more realistic basis for your revenue projections. **What is the difference between TAM, SAM, and SOM?** TAM (Total Addressable Market) is the total global demand. SAM (Serviceable Addressable Market) is the portion reachable within your specific geography and segment. SOM (Serviceable Obtainable Market) is the realistic share you can capture by Year 3. **How do I start my calculation?** Start by using the `calculate_tam_base` tool with either your total market revenue or your potential customer count and average revenue per user. **Can I apply geographic filters?** Yes, use the `apply_sam_refinement` tool to apply a geographic reach ratio (e.g., 0.2 for 20% of the market) and segment target ratios.
