FlashcardsStart the first lesson

Size anything from a few round anchors: segment the population, count one location, turn an installed base into annual sales, size a B2B market, and say which assumption matters.

BBasic3 lessons

  1. 1Anchor numbers and clean roundingA handful of round numbers carries most sizing questions. Memorize them, round on purpose, and say that you are rounding.7 min
  2. 2Segment the populationProOne average user hides the market. Split people into groups that behave differently, size each, and add them up.8 min
  3. 3Sizing one business from the insideProHow much does one laundromat, garage, or clinic make? Count capacity, then utilization, then price. This is the supply side question in its purest form.8 min

  1. 4Stock versus flow: installed base and replacementProMany markets are annual purchases of things people already own. Annual sales are the installed base divided by its lifetime, plus net growth. Confusing the two is the most common sizing error.9 min
  2. 5Sizing B2B marketsProBusiness markets start from a count of businesses, not people. Segment by size, because a 5 person office and a 5,000 person company buy very differently.9 min
  3. 6Ranges, sensitivity, and the decisionProA market size is only useful next to the decision it informs. Narrow total market to what the client can reach and win, give a range, and say which assumption moves it most.8 min
