Here's a neutral and interesting summary of the text in one paragraph: Launching with a validated idea is crucial for startups to achieve product-market fit, and it can be done through a continuous cycle of feedback with customers. Garrett Moon, co-founder of CoSchedule, shares his experience on how he worked with paying customers to validate his idea early on, using mockups, AdWords buys, and surveys to gather input. He emphasizes the importance of being "stubborn on vision" but "flexible on details," resisting feature creep and building to support customers. The process involves creating a feedback loop through user testing, incorporating tools like Intercom, and engaging users in the product development process. By including the entire team in this process, startups can ensure that their product meets real customer needs, leading to a successful launch with a validated idea.
