Marketers often mistake strategic positioning (finding a niche) for true category creation. A new category introduces a solution to a problem customers haven't yet articulated, requiring education on why they need a thing they've never bought before.

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.

David Aaker posits that true market growth comes only from disruptive innovation, not from "my brand is better than yours" incrementalism. He criticizes seminal works on innovation for ignoring that branding is essential to position the new category, build barriers to entry, and make the innovation successful.

Shopify's evolution shows that initial TAM estimates can be conservative. By strategically expanding into adjacent "horizons" like payments, companies can "add a zero" to their market opportunity. This justifies long-term growth and high valuations, a lesson Bessemer now applies to its portfolio.

Companies like Amazon (from books to cloud) and Intuitive Surgical (from one specific surgery to many) became massive winners by creating new markets, not just conquering existing ones. Investors should prioritize businesses with the innovative capacity to expand their TAM, as initial market sizes are often misleadingly small.

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.

When evaluating revolutionary ideas, traditional Total Addressable Market (TAM) analysis is useless. VCs should instead bet on founders with a "world-bending vision" capable of inducing a new market, not just capturing an existing one. Have the humility to admit you can't predict market size and instead back the visionary founder.

The true advantage for new AI-native companies lies not in simply using AI tools, but in building entirely new business models around them. This mirrors how Direct-to-Consumer brands leveraged Shopify not just to sell online, but to fundamentally change distribution, marketing, and customer relationships, thereby outmaneuvering incumbents.

Instead of competing on commodity products, Shopify aimed to create a 'monopoly on all products that are actually interesting.' This strategy focused on empowering creators of unique goods, disintermediating Amazon's dominance.
