As startups grow, they're bombarded with opinions about their products from various sources, including customers, teammates, advisors, investors, media, and even non-customers who claim to represent others. However, not all feedback is created equal, and some types of feedback should be ignored due to their lack of relevance or accuracy. Aspirational statements, where people express what they want without considering the context or feasibility, can be misleading and often don't translate into actual behavior. Hypothetical or espoused behavior, such as predicting how customers will behave in certain scenarios, is also unreliable and should not be taken at face value. Third-party statements, which come from non-customers who claim to know what others might want or need, are particularly problematic and can lead to misguided product decisions. To build a successful product, it's essential to focus on real problems that customers are trying to solve, rather than chasing after aspirational goals or hypothetical scenarios.
