The article challenges the common startup trap of perfecting a product in isolation before launch. Drawing on Y Combinator and Gmail founder Paul Buchheit's "90/10 rule," it advocates releasing a Minimum Viable Product (MVP) quickly to gather real customer feedback, then iterating. Key insights: (1) customers won't validate your idea until they actually use it; (2) early manual work reveals genuine problems better than building systems based on assumptions; (3) the 90/10 principle—solve 90% of the problem with 10% of resources—beats shipping in 3 years. Perfect for Thai SMEs planning product launches.
