Galloway proposes a simple test for disruption risk: compare an industry's price increases with inflation, then ask whether underlying innovation justifies the gap. If prices have risen far faster while the customer experience has barely improved, incumbents have created both dissatisfaction and a margin pool that challengers can attack. He uses cable as an example of major price increases without corresponding innovation, helping explain Netflix's opportunity. The test is a screen rather than a complete forecast. Analysts must also map structural defenses, especially control of distribution. Netflix still depended on cable providers' pipes, so the same incumbents exposed by the price-value gap retained power over delivery. The framework therefore combines an economic warning signal with a final gatekeeper check.

Core principles
- 01Prices rising faster than inflation create customer pain and economic room for challengers.
- 02Underlying innovation can justify higher prices; stagnation cannot.
- 03A widening price-value gap is a practical signal of disruption risk.
- 04Control of distribution can delay disruption even when the gap is large.
How to run it
- 1
Measure price growth
Collect a meaningful history of prices paid by customers, including mandatory fees where relevant. Calculate the cumulative and annualized increase.
Pro tip Use the customer's total bill rather than an advertised entry price.
Watch out A short window can confuse temporary volatility with structural pricing.
- 2
Set the inflation baseline
Compare industry price growth with general inflation over the same period. Quantify the excess increase rather than relying on a sense that prices feel high.
Pro tip Keep dates and compounding consistent in both series.
Watch out Mismatched periods make the gap meaningless.
- 3
Audit innovation
List the improvements customers actually received while prices rose. Judge whether quality, access, convenience, or outcomes plausibly justify the premium over inflation.
Pro tip Prioritize changes customers value rather than internal upgrades.
Watch out Higher operating complexity is not automatically customer innovation.
- 4
Find the challenger opening
Identify new models that can offer a better price-value equation. Look for customer behavior showing willingness to leave the incumbent bundle.
Pro tip Target the most painful component of the incumbent offer first.
Watch out A visible gap does not guarantee that a challenger can acquire customers profitably.
- 5
Map the gatekeeper
Determine whether incumbents control pipes, channels, licenses, or another dependency the challenger still needs. Adjust the disruption thesis for that retained power.
Pro tip Model how the gatekeeper could raise costs or restrict access.
Watch out A superior offer can remain vulnerable when it does not control distribution.
In the wild
Galloway points to large cable price increases without matching innovation as a signal that the industry was open to disruption. Netflix offered a new model, but its reliance on cable providers' pipes remained a major hurdle.
→ The test identifies both the incumbent's exposed price-value gap and the challenger's distribution risk.
Common mistakes
Comparing prices alone
Price increases may be defensible when customers receive substantial underlying innovation.
Counting internal change
Operational activity is not innovation unless it improves customer value.
Ignoring distribution power
An incumbent may remain dangerous when the challenger depends on its infrastructure.
Is it for you?
Best for
It is best for investors, founders, and incumbent leaders evaluating industries with long price histories and observable customer outcomes.
Not ideal for
It is not ideal for markets where quality changes are hard to measure or prices are dominated by volatile inputs rather than incumbent strategy.
From the transcript
“If you want to understand how likely you are to be disrupted. It's pretty easy.”
“You just look at what is our prices relative to inflation”
“if our prices have gone way more inflation and there's no underlying innovation, Cable massive price increases, no innovation, everybody gets into it.”
