Founders who have truly 'found' demand can break free from copying other startups' playbooks. They can confidently deploy unique tactics in product or marketing that seem strange to outsiders but perfectly fit their specific, proprietary understanding of customer needs, leading to outsized success.

To determine if a startup will succeed, analyze the sequence of events. Did organic customer demand and behavior exist before the startup created its supply (product, messaging)? If the startup is trying to force motion with its supply, it's a sign of conjuring demand and a higher risk of failure.

Successful startups tap into organic customer needs that already exist—a 'pull' from the market. In contrast, 'conjuring demand' involves a founder trying to convince a market of a new worldview without prior evidence. This is a much harder and less reliable path to building a business.

Founders mistakenly treat their product idea as fixed while searching for customers. The correct mindset is the reverse: customer needs are a fixed reality. Your product is the variable you must shape to fit that reality, not the other way around.

The moment you find product-market fit is not a time to celebrate; it's a signal that competitors will soon flock to your space. The founder’s immediate reaction was paranoia and an urgent need to build a moat, raise capital, and scale aggressively. The discovery of 'gold' means you must instantly shift from exploration to defense.

Having paying customers doesn't automatically mean you have strong product-market fit. The founder warns against this self-deception, describing their early traction as a "partial vacuum"—good enough to survive, but not to thrive. Being "ruthlessly honest" about this gap is critical for making necessary, company-defining pivots.

When sales stall, founders assume the market isn't interested. More often, it's an execution problem: they fail to listen to clear demand signals or pitch irrelevant features, creating a self-inflicted "demand problem."

Using a child's toy analogy, demand is a pre-existing hole (e.g., a star shape) and your product is the block. Founders fail when they build a block and then search for a hole it fits. The real job is to first deeply understand the shape of the hole, then craft a block that fits it perfectly.
