An offering gap is something customers in a market should be able to buy but currently cannot. Pabrai's method starts with observation: compare a growing area with established areas and identify a missing service whose absence creates inconvenience. Enter with the smallest reversible test rather than a complete operation. His barber example uses a subleased storefront, used equipment, and one operating day per week in a new township. If that day fills, add another day; if demand keeps filling the schedule, grow toward full-time operation. Early scarcity may support premium pricing because customers avoid travel, but capitalism will attract competitors and reduce that premium. The test therefore validates demand cheaply; it does not guarantee a permanent advantage or excuse regulatory and safety obligations.
Origin
Pabrai says his father was skilled at identifying 'offering gaps.' He explains the idea through a hypothetical barber testing one day per week in a growing township with no barber shop.
Core principles
- 01Observe what a growing market lacks
- 02Existing demand may be easier to serve than a novel desire
- 03Enter with a reversible commitment
- 04Expand only when utilization earns the next step
- 05Early scarcity may support a premium but attracts competition
How to run it
- 1
Observe market change
Find a growing population, new behavior, or transferred concept that creates demand before supply catches up.
Pro tip Compare the new market with nearby mature markets.
Watch out Population growth does not prove demand for every service.
- 2
Name the missing offer
Specify the unavailable product or service and the inconvenience customers currently endure without it.
Pro tip Quantify the travel, delay, price, or effort the gap imposes.
Watch out A missing offer may be absent because demand or economics are weak.
- 3
Design a reversible probe
Use limited hours, used assets, a sublease, or another small commitment to test real purchases.
Pro tip Make the probe complete enough to deliver the actual customer outcome.
Watch out Do not bypass licenses, insurance, or safety standards.
- 4
Measure the response
Track bookings, utilization, repeat use, and willingness to pay during the limited test.
Pro tip Notice whether convenience supports a temporary premium.
Watch out Initial novelty may overstate recurring demand.
- 5
Expand by one increment
Add the next day, location, or capacity unit only after the current one fills consistently.
Pro tip Make each expansion another test rather than a forecast-driven leap.
Watch out Growth can introduce fixed costs that remove the original asymmetry.
- 6
Prepare for normalization
Assume successful economics will attract competitors and plan how to retain customers after scarcity disappears.
Pro tip Use the early period to build service quality and customer habit.
Watch out An offering gap is an entry point, not automatically a durable moat.
In the wild
Pabrai imagines a barber noticing that a fast-growing township between two established towns has no barber shop. The barber subleases a small storefront, buys used equipment, and opens only on Wednesdays before adding Tuesday when demand fills the first day.
→ The barber validates demand and expands with little initial commitment, while recognizing that later competitors may normalize prices.
Common mistakes
Building full capacity first
A large initial lease, staff, and equipment commitment removes the reversibility that makes the probe informative.
Confusing scarcity with a moat
The early premium can disappear when competitors enter, so temporary absence is not durable protection.
Is it for you?
Best for
It is best for local or transferable services where demand can be tested with limited equipment, rent, and operating time.
Not ideal for
It is not ideal when regulation, fixed costs, or safety requirements make a small informal pilot impossible.
