The primary piece of advice is to truly understand your customers. It might seem obvious, but many individuals assume that a particular customer will require their service. They become enthusiastic about their solution and technology, and only after developing the solution, platform, or service, do they begin seeking out customers who might match their offering. However, the issue with this approach is that entrepreneurs can end up wasting a significant amount of time and money trying to create something for a small number of customers. Instead, the better approach is to first define the problem, identify a broad audience or a large group of individuals, and then craft a solution that addresses a specific niche problem that, for example, might be shared by around 100 people.
