You have signups, but how do you make sure that you have the product-market fit?

As an early stage startup founder, my big million dollar question at the moment is to find the first set of customers who will pay for an early stage product. Keen to understand how other founders / makers reached this milestone.

I will start it off with a book I really enjoyed recently 1+1=3 by Dave Trott. I would highly recommend!

As founders, we often wear multiple hats: product manager, engineer, marketer, all in a single day. I'm curious to hear how other founders manage the context switching and the different types of thinking and focus required for these different roles.
