The New Era of Assortment Calls for More Than a Hero Product
In today’s CPG landscape, the old “volume at any cost” mindset is being replaced by a more disciplined approach to growth. For insurgent brands, the move from a single hero product to a broader assortment can be one of the hardest stages of scaling.
Success is no longer just about getting more space or facings. It requires a focused assortment strategy where new flavors, formats, and extensions are used to earn more shelf space. It also means understanding how retailers evaluate shelf productivity and where a brand’s assortment truly adds value.
A common assumption is that growth comes from adding more SKUs. This ignores the key challenge that comes with complexity: more expenses. Too many products can strain operations, reduce margins, and confuse shoppers; it ties upvaluable inventory dollars that can be spent on something else. Complexity is not just a brand problem, it is a retailer problem too, because every underperforming SKU steals space from something more productive.
Strong brands take a different approach. With shrinking lead times, they have to expand efficiently and strategically without letting anything fall off track.
When you’re working smarter, not harder, as an insurgent brand, you must assess SKU expansion with stringent criteria. Each new SKU should:
Attract new shoppers
Increase basket size
Fill a real gap in the category
Retailers aren’t interested in novelty for novelty’s sake. They want products that show clear, proven performance, especially when pressure is high, margins are tight, and line reviews are more competitive than ever.
Brands Need to Understand How Retailers Think
Retailers are under pressure to make better use of limited shelf space. In many cases, store footprints have shrunk and costs are increasing, so every product must perform. To combat this, retailers reward products that bring in new shoppers and increase total basket value. That’s their primary objective, and it’s a win-win for both retailers and brands.
The most important concept in retail decision-making is incrementality, meaning the product drives new, additional revenue for a brand rather than simply stealing sales from existing items. This adds complexity without growing the category. Strong brands know not to lead conversations with “we have more SKUs.” Instead, they come with proof that the new SKU creates net-new value.
A product is truly incremental if, upon its removal from the shelf, the shopper leaves the brand (or category) entirely rather than just switching to another one of your available flavors or formats. If they simply switch to your other product, that is called transferable demand, and the original SKU was not actually driving incremental growth.
What Retailers Look For
Buyers often focus on both the science and the art of assortment decisions. On the analytical side, they look at productivity per door, how well the product sells in each store, along with shelf performance, how changes to the assortment affect the category, and opportunity gaps, where the retailer is underperforming compared to the market. There is also a visual and intuitive component to assortment planning, how products show up on shelf, how they create a cohesive and compelling display, and whether the assortment feels complete and easy for shoppers to navigate.
When reviewing a brand’s SKU count, retailers are also looking for brand maturity, the ability to manage a broader assortment, consumer trust in new product areas and clear proof that new SKUs will grow total category sales.
Line reviews are where this logic becomes real. Retailers want brands that can walk in with a clear story backed by data, shopper logic, and a plan for shelf productivity; novelty and category experts are also in demand.

The Expansion Levers: Flavors, Formats, and Functional Extensions
Smart expansion is not about simply adding more products. It is about giving retailers better ways to sell the brand by meeting specific shopper needs and filling gaps in the category. By focusing on key levers of flavors, formats, and functional extensions, fast-growing brands can earn more shelf space and improve overall shelf performance.
Flavor and Format Expansion
The leading insurgent brands use data and shopper feedback to guide innovation, making sure every new product has a clear purpose. OLIPOP, for example, used social listening and Amazon reviews to spot strong demand for an Orange Cream flavor. What started as a customer request became a core product that helped the brand grow to over 50,000 stores.
In a similar way, Chomps expanded its grass-fed beef sticks into chicken and turkey options. It also added mini-stick formats to hit different price points and use cases, helping it grow into 30,000 stores. Jackson’s shows the same kind of focus, using new flavors and pack formats, like 24-count multipacks for club stores, to reach more shoppers and occasions, such as lunchbox prep.
This approach ensures brands are not just adding products for the sake of it, but instead creating more opportunities for placement and building retailer confidence.
Retailer Exclusives
Creating products just for specific retailers is a powerful way to earn more shelf space. It gives the retailer something unique that competitors cannot offer. Liquid Death has done this well by launching exclusives like “Pina Killada” at Target and “Deathberry Inferno” at Walmart.
These exclusives create a win-win: the retailer gets a unique product to attract shoppers, and the brand gains more shelf space. OLIPOP is using a similar strategy by designing slim cans just for convenience stores, matching the needs of on-the-go shoppers.
Adjacent Expansion
Successful growing brands often expand beyond their main product into nearby categories. This helps them evolve from a single product into a broader brand. Once Upon a Farm started with refrigerated baby food pouches and expanded into kids’ snack bars and protein-rich baby meals.
This allowed the brand to show up in different parts of the stores (like the baby aisle, dairy section, and snack bars) reaching more shoppers. As a result, it now averages over 20 products per store across 25,000 locations.
These moves help brands build stronger relationships with retailers by showing they can bring in new shoppers and increase spending, no matter where their products are placed.
Case Studies in Disciplined Scaling
Several fast-growing brands worth learning from. Each brand started with a strong core.
Brand | Starting Point | SKU Expansion Strategy | What Made It Work | Retail Impact |
Canned still water | Added flavored sparkling water, iced tea, and retailer-exclusive flavors | Expanded into adjacent beverage categories and created retailer-specific demand | Earned more shelf space and became a multi-category player | |
Functional soda with core flavors | Turned high-demand and nostalgic flavors into permanent SKUs | Used consumer demand signals to guide expansion | Increased distribution and strengthened shelf presence | |
Beef sticks | Added chicken sticks, mini sticks, and multi-pack formats | Covered more occasions and price points | Expanded into more retailers and usage occasions | |
Refrigerated baby food pouches | Expanded into snacks, protein blends, and new formats across store sections | Moved into adjacent categories and in-store placements | Increased SKUs per store and presence across the store | |
Sweet potato chips (better-for-you snacks) | Expanded flavors and pack formats while widening distribution | Matched SKU growth to real placements and retailer demand | More placements, more missions, stronger retailer assortment story |
Managing the Risks of SKU Growth
Growth can create problems if not managed carefully.
Adding too many SKUs can lead to lower margins, strain on your supply chain, increased shopper confusion, and weak product performance. In essence, they have the inverse impact that brands intend by expanding SKUs in the first place.With increased inventory investment, brands are using up their open-to-buy (OTB) planning dollars.
In many categories, most SKUs contribute very little to total sales. This is why smart brands expand and rationalize at the same time. They protect the assortment by pruning what is not working, and they defend margins by keeping complexity under control.
Jackson’s provides an important lesson that brands who value long-term wins do not just “launch” endlessly. They roll out formats and flavors that support a clear shelf role, then they keep the line tight enough that retailers can clearly see what is driving velocity and what is not, allowing them to make more informed business decisions..
Decision Type | What It Looks Like | Why It Works (or Fails) | Outcome |
Good SKU Expansion | Adding a new format (example: single-serve vs. multi-pack) | Meets a new use case or shopping mission | Increases total sales and basket size |
Good SKU Expansion | Launching a flavor that brings in a new audience | Expands appeal beyond current customers | Drives incremental demand |
Good SKU Expansion | Entering an adjacent category with strong brand fit | Builds on existing trust with shoppers | Expands shelf presence across the store |
Bad SKU Expansion | Adding similar flavors with no clear difference | Shifts sales between your own products | Creates complexity without growth |
Bad SKU Expansion | Launching products without data or demand signals | Based on guesswork instead of insight | High risk of low performance |
Bad SKU Expansion | Expanding faster than operations can handle | Strains supply chain and inventory systems | Leads to out-of-stocks and retailer issues |
Bad SKU Expansion | Keeping low-performing SKUs too long | Takes up space that could go to stronger items | Reduces overall productivity |
Strong brands manage this by reviewing their assortment regularly and removing low-performing items. This frees up space, inventory, and resources for products that drive real growth.
Powering Growth Without Losing Shelf Space
It’s easy to overcommit when considering SKU expansion. While more offerings is a product strategy, many brands aren’t ready for the operational complexities that come with it.
The moment you add SKUs, you create more to coordinate across:
Item setup and retailer requirements
Forecasting and inventory planning
Purchase orders, routing guides, and compliance
Warehouse pick complexity (more items, more touches)
Out-of-stocks risk (more ways to miss)
That is why the fastest-growing brands treat operations as part of the shelf-space story. Retailers want confidence that if they expand your assortment, you can keep it in stock, ship it accurately, and execute consistently across stores. It is also why “more SKUs” can become margin drag if the backend cannot keep up.
As assortments expand, many suppliers hit the same wall: managing more orders, more trading partner requirements, and more moving parts. This is exactly the kind of complexity that EDI and fulfillment infrastructure are built to absorb, so growth does not turn into errors, delays, or out-of-stocks that put shelf space at risk.
Insurgent Brands Win by Working Smarter, Not Harder
The fastest-growing brands are not winning by adding more products. They are winning by building disciplined assortments that make the retailer’s job easier and the shelf more productive.
Each SKU should earn its spot by doing at least one of the following:
Driving incremental demand (not just shifting sales). If a new item only cannibalizes, retailers see complexity without upside.
Expanding the brand into a new use case, format, or occasion, backed by real demand signals (not guesswork).
Improving shelf productivity and category outcomes, not just adding novelty. Strengthening retailer confidence that the brand can scale reliably, especially through line reviews where the story must be backed by performance and shopper logic.
The shelf-space playbook is simple: prove value, expand with intent, and keep the assortment tight enough to stay fast. Brands that do this win more facings, build trust with retailers, and grow without letting complexity tax the business.
