Hi all,
I’m practicing market sizing for interviews coming up, and I do not understand why we would not always start with the demand side in regular market sizing? Why would you start with the supply side? That always seem to be more complicated.
Im talking about sizing markets, such as “how big is the market for sunglasses, coffe, sweaters, plane tickets, fuel in a given country». I think it makes sense to start with the population, and then segment that into smaller pieces, by age etc. What do you guys think?
Of course, other guesstimate such as golf balls in planes and similar won’t be solved by this approach, but I’m thinking about regular market sizing.
Would love to hear what you guys think
Best,
A
