"How do I measure the size of the market my start-up will be competing in?
I received that question yesterday from a first-timer. It's an important question.
Here are responsive tips from serial entrepreneurs (who do it with little effort).
EXAMPLE
Let's assume you are going to sell an app to consumers. Specifically, it would help people monitor calories eaten daily by scanning the dish of food they eat, using their smartphone. The company business model (how it makes money) is 90 percent sales, plus 10 percent from advertising.
The numbers you will be generating will be Units and Price per Unit. The mulitiplicant is the economic size of your market.
- Top down: TAM = Total Available Market
- How many end users have an over-weight problem?
- How many have an under-weight problem?
- For (1.) and (2.) how many are
- In the U.S.
- Europe
- S. America
- China
- India
- Rest of World
- What portion of them own a smartphone?
- What portion are
- Obese
- Over weight by 30 pounds or more
- Think of themselves as "over-weight"
- Have serious (doctor treated) health problems related to excess weight
- What portion are
- Seriously under-weight
- Chronically under-weight
- Psychologically under-weight
- The total of the above equals TAM
- Units
- Price per Unit
- Dollars
- Focus: Ideal Customer = SAM = Served Available Market
- Which segments of TAM is your product most appealing to (pick 6)?
- Which segment is most eager to use your product?
- What 2 related segments are next as measured by product appeal?
- In what year will you offer products for each of those 3 market segments?
- Line up these 3 segments like Bowling Pins
- The total of the above equals SAM
-
- Units
- Price per Unit
- Dollars
- Calculate % of TAM
- Which segments of TAM is your product most appealing to (pick 6)?
- Sales: Customer Adoption = SOM = Share of Market
- For each of the 3 Bowling Pins:
- At what rate (% of each of the 3 market segments in SAM) will customers purchase your product, each year, for five years.
- Units
- Price per Unit
- Dollars
- Add the 3 sets of numbers to get your Sales.
- Total Units
- Total Dollars
- Average Selling Price
- % of SAM
- At what rate (% of each of the 3 market segments in SAM) will customers purchase your product, each year, for five years.
- For each of the 3 Bowling Pins:
- Boundaries:
- SAM in early years should be less than 25% of TAM, rarely over 50%.
- SAM below 10% is too small, or TAM is too large, not focused enough, lacks meaning.
- SOM over 30% of SAM is rare. Gorillas of new markets settle in around 30%
- SOM below 10% is too small.
- Your adoption rare may be too conservative.
- Or your product is rather boring, not appealing.
Once you start to follow this example for your start-up, you'll get a feel for how it is done. Avoid looking for other people to measure the market for you. Serial entrepreneurs never do. Instead, they focus on exactly what they are offering to their Ideal Customer, find them in various related markets, and figure out a plan for selling to them, including modifying the first product to appeal to each market segment.
BOTTOM LINE: You can forecast something from nothing. New markets just forming in people's heads is where great start-ups begin. Facebook before Facebook. Google before Google. Even more modest new enterprises think the same way. First-timers can learn it. MBAs can learn it. Giant corporation people can learn it. So can you! Do it and add it to the elements you are using to build your unfair advantage.
I wish you The Best on your Adventure!
