The challenge asks what would have to change to double a meaningful conversion or performance metric while keeping time, money, and headcount fixed. The aggressive target is not necessarily a forecast; it is a device for exposing assumptions that small improvement goals leave untouched. Teams reason from first principles about the customer's decision, the offer, friction, distribution, message, and experience instead of copying industry averages. They then translate the strongest hypotheses into a sequence of real experiments. Even if the metric does not fully double, the process can reveal nonlinear opportunities and produce greater gains than conventional optimization. The constraint prevents the team from answering the challenge merely by buying twice as much traffic or labor.
Origin
Extracted from Marketing Against The Grain during Kipp Bodnar and Kieran Flanagan's discussion of certainty, benchmarks, and top-performing marketers.
Core principles
- 01Benchmarks describe the past rather than define the possible.
- 02Fixed constraints can force structural innovation.
- 03Outlier performance rarely comes from copying the average.
How to run it
- 1
Set the Doubling Target
Choose one consequential metric and ask how it could become twice as good without additional time, money, or people.
Pro tip Use a metric close enough to customer value that doubling it would matter.
Watch out Avoid vanity metrics that can double without improving the business.
- 2
Strip Away Inherited Assumptions
List conventions based on benchmarks, competitors, and historical practice, then reconsider each from the customer's perspective.
Pro tip Ask what function each convention serves and whether another mechanism could serve it better.
Watch out First-principles thinking does not mean ignoring accumulated evidence.
- 3
Design Structural Experiments
Test changes to the offer, audience, message, flow, or channel that could create nonlinear improvement.
Pro tip Combine compatible hypotheses into coherent experience-level tests.
Watch out A series of tiny cosmetic tests is unlikely to reach a step-change target.
- 4
Compound the Learning
Use each result to refine the model and choose the next experiment rather than judging the exercise only by the final doubling.
Pro tip Document why each result supports or weakens the underlying mechanism.
Watch out Do not declare the target impossible after one failed approach.
In the wild
A B2B team challenges itself to double demo conversion without more traffic or staff. Instead of copying benchmark forms, it interviews lost prospects, changes the offer from a generic demo to a role-specific diagnostic, removes unnecessary fields, and tests proof tailored to each segment.
→ The team discovers structural conversion levers that incremental button and headline tests had missed.
Common mistakes
Treating the Target as a Promise
The doubling target is a thinking constraint and experimentation direction, not a guaranteed forecast.
Copying the Market Average
Replicating common tactics tends to reproduce average performance rather than create leverage.
Is it for you?
Best for
Experienced teams with stable measurement and a funnel or channel that needs a step-change in performance.
Not ideal for
Immature systems whose data is unreliable or whose basic execution problems have not yet been corrected.
From the transcript
“what if I had to double this conversion rate with everything else being the same?”
“Same amount of time, money, people, what have you. What would I do?”
“It's thinking through things from first principles.”
