# Add a new growth model every 18 months and protect it from KPIs for 12

## Claim
Every loop decays. Andrew Chen's Law of Shitty Click-throughs, over-optimizing a single channel produces diminishing returns, applies to growth loops as well. Allocate 20–25% of the growth team's annual time to introducing new loops with no metric expectation for the first 12–18 months. Without a runway, every new loop dies before it has a chance to compound.

## Mechanism
A loop's economics are non-linear in time. Months 1–12 produce noisy data and small results. Months 18–36 are where compound effects appear. Most teams kill loops at month 6 because they aren't pacing the existing loops. Pre-allocating capacity *and* removing the ROI gate during the seeding period preserves enough loops to ride out their slow start.

## Conditions
Holds when:
- The org has a stable senior team that can absorb the long horizon politically.
- The new loops are genuinely different growth models, not variants of existing ones.

Fails when:
- The org is in cost-cutting mode and 12-month no-metric work is impossible to defend.
- The loops are added cosmetically (every quarter, "new initiative") without real engineering investment.

## Evidence
> "Most loops decay over 5–7 years; some, like Dropbox sharing, don't. Allocate 20–25% of the growth team's annual time to introducing new loops with no metric expectation for the first 12–18 months."

Elena cites her own experience across Dropbox, Miro, SurveyMonkey, and Amplitude, the durable loops are always the ones that got the multi-year runway, not the ones launched and judged in a quarter.

## Signals
- The team has a named portfolio of loops, currently funding, currently seeding, retired.
- Leadership defends the seeding loops in OKR reviews without ROI justification.
- One in four loops eventually compounds; the rest are killed honestly after the runway.

## Counter-evidence
For pre-PMF or distressed companies, this rule is a luxury. Elena explicitly notes "growth teams cannot fix declining businesses." Add new growth models only when the existing ones are healthy enough to fund the experimentation.
