5 MVP Development Mistakes That Kill Startups Before Launch

Most startups don't fail after launch — they fail because of decisions made before a single line of production code was written. After seeing the same patterns repeat across dozens of early-stage builds, I want to document five of the most common MVP development mistakes and what they actually cost you. Mistake 1: Treating the MVP as a Smaller Version of the Full Product This is the most expensive mindset error you can make. An MVP is not a product with features removed. It is a hypothesis with a delivery mechanism. The question is not "what's the minimum we can ship?" — it is "what is the fastest way to learn whether this problem is real and whether our solution addresses it?"
