Avoid the middle ground. On Running learned that designing for a "hybrid" persona who moves from the gym to a cafe leads to compromises. It's better to create a best-in-class performance product that people choose to wear for style, rather than a watered-down product that serves neither purpose well.

Unlike product marketing, sports marketing cannot control the core product’s performance (wins/losses). The primary job is to build deep, personal connections between fans and athletes. This creates emotional "insulation" where fan loyalty is tied to the people and the brand, not just unpredictable on-court results.

Spotify leveraged its brand love to successfully expand from music streaming into podcasts and audiobooks. This emotional equity provides the necessary consumer trust for diversification, turning brand into a strategic asset for growth beyond the core product.

True Religion strategically defines the objective of each partnership before launch. A collaboration with Ford aimed for mass scale and broad awareness. In contrast, a partnership with fashion brand Bella Donna was specifically designed to attract a new, targeted audience (the Hispanic consumer), showcasing a dual-pronged approach to growth.

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 inspiration can come from unexpected places. On Running's CPO points to the perfume industry's ability to sell an intangible feeling through packaging and branding as a key lesson in creating an emotional connection with consumers, even for highly functional products like running shoes.

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.

A common misconception is that market size is fixed. However, as investor Alex Rampell notes, the market for a product executed exceptionally well can be orders of magnitude larger than for a merely adequate solution. Superior execution doesn't just capture a market; it dramatically expands it.

For celebrities, the most effective path to massive wealth isn't always starting their own company. A more strategic approach is to identify a promising brand and exchange social capital for a significant equity stake, as Roger Federer did with On. This leverages influence without the operational burden of building a business from scratch.
