Marshall rejects fixed channel prescriptions because performance depends on the product, company stage, team, creative strengths, and current platform conditions. A channel that underperforms for one business may be highly effective for another, while advice from a much larger founder may assume resources an early company does not have. The method begins by defining what the channel must accomplish, then auditing whether the team can execute the required content and operations. A founder runs a bounded test and uses company-specific results rather than borrowed certainty. Because platforms move quickly, the conclusion remains provisional. The output is not a permanent ranking of channels, but an evidence-based decision for this product, team, and moment.

Core principles
- 01Channel advice is conditional rather than universal
- 02A channel can work in the market and still be wrong for a particular team
- 03Current tests should outrank another founder's past result
- 04Opinions must change when platforms and customer behavior change
How to run it
- 1
Frame the situation
Specify the product, buyer, company stage, budget, and desired outcome. This prevents advice from a different operating context from becoming an automatic rule.
Pro tip Write down which assumptions would have to match for outside advice to transfer.
Watch out Large-company tactics may depend on staff and budget an early founder lacks.
- 2
Audit execution fit
Assess the team members and agencies responsible for the channel. Match their strengths to the channel's actual creative formats and operating demands.
Pro tip Evaluate specific capabilities such as short video or static imagery, not a generic claim that the team is good at marketing.
Watch out Poor execution does not prove the channel itself is ineffective.
- 3
Run your own test
Design a limited experiment with a measurable outcome and acceptable downside. Dig into the channel far enough to distinguish weak execution from weak fit.
Pro tip Use a predeclared threshold so enthusiasm does not move the goalposts.
Watch out A public revenue claim from another account is not evidence for your unit economics.
- 4
Update with the market
Keep the decision open to revision as platform features, competition, and team capability change. Retest only when a meaningful input has changed.
Pro tip Record the date and conditions behind every channel verdict.
Watch out Do not preserve an old opinion merely because it once worked.
In the wild
Marshall says Trapa was not succeeding on Pinterest, but he knew another company that was. He uses the contrast to show that a poor result for his team does not make Pinterest a bad channel in general; the relevant question is whether a particular product and team can execute it well.
→ Channel evaluation shifts from universal verdicts to company-specific fit.
After favoring performance marketing, Marshall notes that TikTok Shop was not yet available to Australians and says he intended to use it when available. Creator commissions could alter the opportunity, so he explicitly warns that his opinion may change as the platform changes.
→ A dated recommendation remains adaptable rather than becoming doctrine.
Common mistakes
Copying advice without its context
The founder adopts a tactic from a company with a different stage, team, product, or budget.
Blaming the channel for weak execution
A failed attempt is treated as proof that the channel cannot work, even when the team lacked the required capability.
Is it for you?
Best for
It is best for teams deciding where to invest limited marketing time and money.
Not ideal for
It is not ideal when a channel cannot be tested safely or within the company's loss limit.
