Yoon argues that trying to go viral is a poor strategy because the result cannot be reliably repeated, measured, or forecast. Peach and Lily instead asks which marketing levers are predictable and measurable. When a product does go viral, the company treats the extra demand and cash flow as temporary upside, explicitly avoids assuming it will recur in the next planning period, and keeps any new spending inside its normal test discipline. The same rule protects product development: a viral product is not evidence that a similar product will repeat the event. New products still need a problem-solution rationale, scientific support appropriate to the category, and the ability to earn repeat purchase after attention fades. The mechanism converts volatility into a bonus without allowing it to distort forecasts, assortment choices, or the underlying operating model.
Origin
Yoon developed this rule while managing viral attention around Peach Slices and other products. She says the company never holds marketing discussions about how to manufacture virality.
Core principles
- 01Do not build plans around an outcome you cannot reliably repeat
- 02Treat unexpected virality as upside rather than baseline demand
- 03Protect product development from trend-chasing
- 04Require substance and repeat purchase beyond launch attention
- 05Prefer controlled sustainable growth to unplanned spikes
How to run it
- 1
Name repeatable levers
Identify the marketing actions the company can execute again and measure with reasonable consistency. Use those levers as the foundation of the plan.
Pro tip Require an owner, input, expected output, and measurement window for each lever.
Watch out A hoped-for viral post is not a controllable lever.
- 2
Forecast without the spike
Build the next period's baseline without assuming that unusual viral demand will recur. Explain this distinction to retailers and other planning partners.
Pro tip Maintain separate baseline and upside scenarios.
Watch out Using the spike as the new baseline can create inventory and growth expectations the company cannot control.
- 3
Ring-fence the upside
Treat extra cash flow as optional capacity rather than permission to abandon normal discipline. Put proposed uses through the same measured test process as any other spend.
Pro tip Choose reversible tests instead of permanent cost increases.
Watch out Temporary revenue can fund recurring obligations that survive after attention fades.
- 4
Protect the product roadmap
Do not create a similar product solely because the first one went viral. Require the next concept to solve a specific customer problem on its own merits.
Pro tip Review concepts without showing the team viral sales first.
Watch out Trend imitation may produce launch attention without durable value.
- 5
Measure the long tail
Track whether sales and repeat purchase grow after the initial buzz. Judge product strength by sustained customer behavior, not the launch peak.
Pro tip Compare cohort retention before and after the spike.
Watch out A large launch can hide weak repeat demand for months.
In the wild
Yoon says Peach and Lily tells retail partners that an unexpected viral period cannot simply be repeated the following year. The company treats the event as unplanned upside and continues forecasting from its sustainable operating base.
→ The spike does not become an unsupported growth commitment.
Yoon says the company's launches are not usually designed as huge spikes. She describes products that launch at a reasonable level and continue growing as customers return, producing a snowball rather than a brief peak.
→ Long-term sales behavior becomes the product-quality signal.
Common mistakes
Forecasting another viral event
An uncontrollable spike should not become the assumed baseline for the next period.
Copying the viral product
Similarity to a viral item does not prove that the next product solves a durable customer problem.
Spending the spike indiscriminately
Extra cash flow should still be allocated through the company's measured decision process.
Is it for you?
Best for
It is best for brands exposed to social-media spikes, retailer forecasts, and pressure to imitate a viral product.
Not ideal for
It is not ideal as a reason to ignore organic attention that can be converted into repeat customers responsibly.
From the transcript
“Trying to go viral is a really bad strategy because by nature you can't comp that.”
“What is a repeatable predictable marketing lever and how do we measure that?”
“We stick to no, our product development is going to be driven by, you know, problem solution always.”
