Large companies often focus R&D on high-ticket items, neglecting smaller accessory categories. This creates a market gap for focused startups to innovate and solve specific problems that bigger players overlook, allowing them to build a defensible niche.

When large appliance companies like Dyson entered the premium hair tool market, T3 was initially intimidated. However, their massive marketing budgets raised overall category awareness and normalized higher price points. This repositioned T3 as an 'affordable luxury' and ultimately boosted their business, demonstrating that new competition can grow the pie for everyone.

Nike's strategic error was pulling its products from third-party retailers like Foot Locker to focus on direct-to-consumer sales. New Balance capitalized on this by flooding those same stores with its products, scooping up abandoned market share and visibility.

For Numi's novel undershirts, a major challenge was educating the market on the problem and solution. When competitors emerged, they didn't just steal market share; they helped validate the category and shoulder the burden of customer education, ultimately expanding the total addressable market.

The recession acted as a tailwind for e.l.f. As consumers sought value, major competitors launched expensive drugstore lines that failed. This created a market vacuum and opened up precious retail shelf space for e.l.f. to fill.

Major retailers often dislike when a single large company, like Zen in nicotine, dominates a category. This gives the incumbent too much leverage on pricing and placement. Consequently, retailers are often receptive to new, high-potential brands that can introduce competition and shift the power dynamic back in their favor.

Rabbit's go-to-market was a calculated attack on Humane. They strategically timed their CES launch, set a low one-time price to contrast Humane's subscription model, and structured the keynote to directly compare the two products.

Many marketers mistakenly start with the goal of creating a new category. However, a new category only emerges as a downstream consequence of a strong, existing demand that is poorly served by all current products. The demand must exist before a new category can be successfully established.

For new CPG brands, aggressive marketing before achieving near-national distribution is a critical error. When excited customers can't find the product in their local store, they often buy a competitor's alternative (e.g., White Claw instead of Happy Dad). This funnels demand and new customers directly to established rivals.
