Thanks for the responses. You've been fortunate that you could utilise a tangible and working prototype to gain customer insight. Congrats on building this into a business. Other approaches (like lean) encourage you to first evaluate your idea/concept before building a prototype. When a concept has some good potential then going straight to prototype can work. Its having this confidence that has worked for you.
