1. 018How would you perform a whitespace analysis?Stock pitchIntermediatecase studyViking Global InvestorsQuantitative Research · New York · 2024

   Say this

   Whitespace analysis maps where a company could sell but currently does not, and then asks how much of that gap is actually reachable. It is a growth-runway tool: define the full addressable grid, mark what is already penetrated, and size the remainder with an honest win rate.

   Then walk it

   1. Build the grid explicitly. Two or three axes that matter: customer segment by geography by product. Cells are combinations, and every cell gets a size and a current penetration.
   2. Get the penetration from disclosure and bottom-up data rather than management's TAM slide. Customer counts, store counts, licence counts, segment revenue, and where possible third-party data like app downloads or job postings.
   3. Then subtract what is not really reachable. Cells owned by an entrenched incumbent with switching costs, cells where the product does not fit without heavy investment, cells where regulation blocks entry. That haircut is the analytical content of the exercise.
   4. Then convert it to a number the model can use. Reachable whitespace times a realistic win rate over a defined period equals incremental revenue, and I would keep the win rate low enough to be defensible, often 10 to 20 percent rather than a third.
   5. Cross-check against history. If the company has been adding 400 customers a year and your whitespace implies 2,000 a year, the whitespace is not the constraint, execution is. Reconcile the two or drop the analysis.
   6. The limitation to say out loud: whitespace tells you the ceiling, not the path. Plenty of companies with enormous whitespace never grow, because the gating factor is sales capacity or the economics of serving the marginal customer, not the size of the opportunity.

   Where candidates lose it

   Producing a large TAM number and calling it a thesis. TAM slides are marketing. A credible whitespace analysis is mostly about what you exclude and the win rate you apply, and it must reconcile with the company's demonstrated rate of expansion.

   Expect next

   • How would you validate the penetration numbers independently?
   • What win rate would you use, and why?
   • Where does this analysis mislead you?
