Peach and Lily's retail mantra is to go an inch wide and a mile deep. Instead of treating maximum shelf space as the goal, the company focuses on making each existing SKU highly productive. Yoon argues that taking more space creates pressure to fill it with products that may not be needed, spreads limited marketing attention across too many launches, and leads to discontinuation and replacement cycles when weaker SKUs miss retailer goals. The decision rule is to keep the footprint stable while current products can still deliver growth through better productivity. Expansion begins only when the assortment is well above department benchmarks and effectively bursting at the seams. Even then, the company seeks the smallest increase and considers kits or educational materials before filling every new slot with another product. Geographic expansion follows the same depth-before-breadth logic.
Origin
Yoon says Peach and Lily developed the mantra while expanding through retailers such as Ulta Beauty. The company repeatedly negotiated to keep less space and grow through stronger SKU productivity instead.
Core principles
- 01More shelf space is not automatically better growth
- 02Existing SKU productivity should lead expansion
- 03Innovation should follow customer need rather than space-filling pressure
- 04Marketing attention is finite across a large assortment
- 05Expand only when the current footprint is demonstrably constrained
How to run it
- 1
Audit current productivity
Measure each SKU's sell-through and compare it with the retailer's department goals. Identify whether growth remains available within the current footprint.
Pro tip Review the assortment at SKU level rather than relying on total brand sales.
Watch out Strong aggregate sales can conceal weak products.
- 2
Deepen the current footprint
Improve education, community engagement, loyalty, and product support around the existing assortment. Concentrate marketing where it can increase productivity.
Pro tip Give each product enough attention to earn repeat purchase.
Watch out Adding products can dilute the support available to proven ones.
- 3
Decline premature space
When a retailer offers more space, test whether the same growth goal can be reached through better productivity. Negotiate to keep the footprint stable when expansion is unnecessary.
Pro tip Frame the discussion around shared productivity goals.
Watch out Space creates an obligation to fill and support it.
- 4
Wait for the seam to burst
Expand only when current SKUs are consistently above relevant benchmarks and the footprint itself is limiting growth. Require evidence across the assortment.
Pro tip Define the expansion trigger before the next offer arrives.
Watch out One exceptional hero SKU may not justify a broad assortment increase.
- 5
Minimize the expansion
Take only the space that current demand and the innovation pipeline justify. Use kits, duplicated facings, or education cards instead of inventing products merely to fill shelves.
Pro tip Ask how little new complexity is needed to unlock the next stage.
Watch out Rushed innovation can damage product quality and create later discontinuations.
- 6
Repeat before going wider
Prove depth in the current retailer or geography before entering another. Treat new markets as a later opportunity rather than an urgent requirement.
Pro tip Make operational readiness part of the expansion gate.
Watch out Being everywhere can mask shallow performance in each place.
In the wild
Yoon says Peach and Lily became a top-performing prestige skincare brand at Ulta while occupying much less shelf space than many peers. The company sometimes declined offers of more space and proposed hitting growth goals by improving the productivity of existing products.
→ The brand pursued concentrated sell-through before expanding its physical footprint.
When more space became necessary, Yoon says the company considered using a kit and an education card, then adding only three SKUs instead of creating nine products to fill every slot.
→ The expansion added less innovation and marketing complexity.
Common mistakes
Treating space as the goal
More shelf space can create complexity without improving the productivity of the assortment.
Developing products to fill slots
Shelf pressure can rush innovation and create products that are not grounded in customer need.
Expanding before depth
Entering more retailers or geographies before the current channel is strong spreads attention and operations too thin.
Is it for you?
Best for
It is best for consumer brands already selling through brick-and-mortar partners with SKU-level productivity data.
Not ideal for
It is not ideal when the current footprint is too small to establish reliable sell-through evidence.
