Founders obsess over perfecting downstream tactics like discovery interview scripts. This effort is wasted if their upstream understanding of why people buy is wrong. Getting the fundamental "upstream" concepts right, like customer pull, is the only way to ensure downstream activities are even relevant.
Traditional Ideal Customer Profiles (ICPs) based on static attributes like job title or company size are flawed. A superior ICP is defined by "pull"—the dynamic state of being actively stuck trying to do something but blocked by current options. All downstream tactics, from product to sales, flow from this definition.
Founders mistakenly believe sales proficiency is paramount. In reality, sales skill is a downstream concern. If you identify a customer with immense "pull"—someone so stuck they'd do anything for a solution—even a terrible sales call will succeed. The priority is finding that desperate customer, not perfecting the pitch.
Reframe the sales call mindset from persuasion to diagnosis. The goal is not to pressure someone into buying but to calmly determine if they are stuck and need help. This approach removes stress for the founder, improves signal quality, and creates a more genuine interaction. If they don't need help, that is a successful outcome.
The pre-product-market fit stage is a "pain cave" of infinite possibilities and unclear direction. The PULL framework provides a structured, predictive method to escape this uncertainty. It focuses on identifying the specific conditions that compel a purchase, offering a clear path to achieving product-market fit.
Building a startup requires following a specific sequence. First, internalize the theory of "pull." Second, define the Ideal Customer Profile (ICP) based on that theory. Third, shape a product concept to match their pull. Only then should you address downstream elements like pricing or outreach. Violating this order invalidates all subsequent work.
