Reachable market applies the share you can serve given geography, language and channel. Every figure traces back to something you typed. ### Apply a realistic share Obtainable revenue is the reachable market times the share you expect to win. The tool compares that share with a ceiling for your business type, so an optimistic input gets flagged instead of rewarded. ### Test the revenue goal The tool divides your goal by the reachable market to find the share you would need. Under the ceiling it fits, up to twice the ceiling it is a stretch, beyond that the market is probably too small. *Before you trust the output* ## The number is only as good as your customer count Most market sizing fails at one input: how many potential customers exist. A guess pulled from a report headline is worse than a short list you counted yourself. Count a real slice first, such as the businesses in one city or one category, then scale it up with a stated assumption. Then go and talk to a handful of those customers. A calculator tells you whether the arithmetic can work. A conversation tells you whether anyone cares. - Write the source next to every input - Count a small slice before scaling it up - Check the price against what buyers already pay ## Questions about this market research tool ### Is this market research tool free? Yes. It is free, needs no account, and runs entirely in your browser. Nothing you type is sent to a server. ### Where do the numbers come from? From you. The tool multiplies the inputs you give it: customers, reach, price and share. It does not pull data from a database, so it never shows a figure you cannot trace back to an assumption. ### What is the 1 to 5 percent share ceiling based on? It is a rule of thumb, not a published statistic. A new entrant rarely wins more than a few percent of a reachable market within three years, so the tool uses 3% for B2B, 1% for consumer apps, 2% for marketplaces and 5% for local services as a stress test. Replace it with your own evidence once you have some. ### How is this different from a market research report? A report gives a top-down number for an entire industry. This tool builds the figure bottom-up from customers you could actually serve, which is closer to a revenue plan. Use the optional report field to compare the two. ### Where do I find the number of potential customers? Start with public sources: census and business registries, trade association member counts, LinkedIn or Google Maps searches, app store category sizes. Write down the source next to the number so you can defend it. ### Does it replace talking to customers? No. The tool sizes demand on paper. Whether people will pay is a different question, and only interviews, pre-sales or a landing page test can answer it. ### What if my goal does not fit? Change one lever at a time. A higher price, a wider reach or a narrower goal each move the verdict. If none of them works on realistic inputs, the market as you described it is too small for that goal. ## Market size is one risk. What about the rest?
