A founder of an athletic underwear brand faces a classic strategic choice. One path is to focus narrowly to dominate a niche, like Spanx did. The other is to expand into adjacent products (like sports bras) to create a complete brand system. This highlights the core tension between operational focus and building a broader brand platform.

Product-led models create deep loyalty and organic demand, providing a stable business foundation. Marketing-led models can scale faster but risk high customer churn and rising acquisition costs if the product doesn't resonate, leading to business volatility. An ideal approach blends both strategies for sustainable scale.
A company with modest growth experimented with niche content for a small user segment, revealing a massive, underserved market. This led to a second, separate app that quickly surpassed the original product's revenue and drove hyper-growth, challenging the "focus on one thing" dogma.
While adjacent, incremental innovation feels safer and is easier to get approved, Nubar Afeyan warns that everyone else is doing the same thing. This approach inevitably leads to commoditization and erodes sustainable advantage. Leaping to new possibilities is the only way to truly own a new space.
The tension between growth and profitability is best resolved by understanding your product's "runway" (be it 6 months or 6 years). This single piece of information, often misaligned between teams and leadership, should dictate your strategic focus. The key task is to uncover this true runway.
The "build it and they will come" mindset is a trap. Founders should treat marketing and brand-building not as a later-stage activity to be "turned on," but as a core muscle to be developed in parallel with the product from day one.
The key to effective portfolio entrepreneurship isn't random diversification. It's about serving the same customer segment across multiple products. This creates a cohesive ecosystem where each new offering benefits from compounding knowledge and trust, making many things feel like one thing.
A brand's strength can be measured by its "durability"—the permission customers grant it to enter new categories. For example, a "Nike hotel" is conceivable, but a "Hilton shoe" is not. This mental model tests whether your brand is defined by a narrow function or a broad customer relationship.
Counterintuitively, focusing on a single, powerful SKU can be more effective for initial growth than launching a full product line. It simplifies your message, makes you attractive to distributors who value efficiency, and builds a strong customer base before you introduce new offerings.
Eliminating a popular and profitable product line can be a wise long-term strategy. If a product, even a bestseller, creates brand confusion or pulls focus from your core vision, cutting it can strengthen your primary brand's identity and lead to more dedicated growth.
Jane Wurwand of Dermalogica deliberately launched a multi-product line to establish a complete skincare regimen. This set them apart and communicated their educational philosophy. She maintained intense focus, however, by refusing to diversify into adjacent categories like makeup or hair, proving focus can apply to a category, not just one product.
