Idea validation
“In terms of validation, I just build apps that solve my own problems… I will always be my first customer, and so I always know exactly what's needed in the product, what are the requirements, what works and what doesn't.”
Build apps that solve your own problems — be your own first customer
Skip elaborate validation rituals and build apps that solve your own problems. Being your own first customer removes the guesswork about requirements and feature priority — you always know what works because you're the one using it daily.
