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.

The advice to "serve a customer for 10 years" is incomplete. A more foundational step is to first understand your own authentic identity. Building products that reflect who you are naturally attracts the right customer, creating genuine "customer-founder fit" and avoiding the burnout of "putting on a show."

Instead of chasing trends or pivoting every few weeks, founders should focus on a singular mission that stems from their unique expertise and conviction. This approach builds durable, meaningful companies rather than simply chasing valuations.

The dominant VC narrative demands founders focus on a single venture. However, successful entrepreneurs demonstrate that running multiple projects—a portfolio approach mirrored by VCs themselves—is a viable path, contrary to the "focus on one thing" dogma.

Product management "range" is developed not by learning domain-specific facts, but by recognizing universal human behaviors that transcend industries—the desire for simplicity, convenience, or saving time. Working across different verticals hones this pattern-matching skill, which is more valuable than deep expertise in a world of accessible information.

True diversification doesn't come from being a generalist, but from achieving undeniable mastery in one specific domain. This deep expertise becomes your leverage—your "in"—to access rooms, build credibility, and then expand horizontally into other ventures like production, investing, and brand partnerships.

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.
