Prototyping is crucial; instead of spending months on a project before showing it to anyone, build prototypes and share them throughout the design process to gather feedback early.

Rapid prototyping and user testing are essential; focus on getting a functional prototype out quickly, using tools to create clickable mock-ups or writing throwaway code to test ideas with users, as building a fully functional product before testing can be an expensive mistake.

It's important to gather user feedback early, even with a prototype, to ensure you're addressing real problems and providing value to your customers.

If you're not prototyping and building to see what you want to build, I think you're doing it wrong. Prototyping is essential for effective product development.

Prototyping is an incredibly valuable tool, even if I personally haven't utilized it much. I tend to rush to build and ship my code, but I recognize that taking the time to prototype can lead to better outcomes.

We learned that building too much technology too quickly can be a mistake; it's essential to focus on what's most needed and to iterate based on user feedback.

It's crucial to engage with customers early on, as they can provide valuable feedback that helps you build a better product than if you just focus on perfecting the prototype first.

Prototyping allows for rapid testing and feedback, which is crucial for understanding product dynamics before scaling with engineering resources.

A common mistake technical founders make is to build products first and then talk to users, which often leads to choosing the least impactful tasks for the week.
