1. 028How would you perform a whitespace analysis?Company analysisHardtechnicalViking Global InvestorsQuantitative Research · New York · 2024

   Say this

   Map what the company currently sells to whom, map the total set of customers and products it could serve, and the gap between them is the whitespace. Then test whether the company can actually reach it.

   Then walk it

   1. Build the current position first: revenue split by product, by customer segment, by geography. You need the base to measure the gap from.
   2. Then size the addressable set honestly, bottom-up. Number of potential customers times realistic spend per customer, not a top-down market report number that includes everyone.
   3. The whitespace is the difference: customers in the addressable set who do not buy, and products the existing customers buy from someone else. The second is usually the higher-probability opportunity, because the relationship already exists.
   4. Then the feasibility test, which is where most whitespace analyses fail. Does the company have the product, the sales capacity and the right to win? Whitespace that requires capability it does not have is not an opportunity, it is a wish.
   5. Then quantify what the market is paying for. If the current price implies the company captures a third of the whitespace, and your work says it captures a tenth, you have a short. That conversion from market map to expectation is the actual investment output.

   Where candidates lose it

   Producing a large total addressable market number and calling it whitespace. The analytical value is entirely in the feasibility filter and in converting the result into what is priced in.

   • How do you size a market bottom-up?
   • How much of that is in the price?
   • How would you verify penetration rates?
