In my own process of validating + building GummySearch, I have personally talked to over 100 early stage founders who are validating, building, launching, and growing their own products.
Time and time again, I've seen 2 stories unfold. The founder that is so excited about their product idea that they build it without talking to anyone, only to be disappointed when nobody uses their product upon launch. And the founder that took the necessary steps upfront to validate their product and is rewarded with happy customers that are willing to purchase the product the second it becomes available.
I took all I've learned myself and written up a blog post on idea validation here. If you're going through this stage of your journey, it might help you.
Also, I'm going to try to keep this blog post updated. If there's anything you think I should add, would welcome the suggestions!
