I bet if 100 people each threw 6k at a designer and 3k at a developer for the same exact product.. about 90-95 of them would not work, or be complete trash.
It seems really hard for a non developer to build a MVP. (I am a developer so not personally, but looking back at reports of someone who does the non-dev MVP thing).

Nowhere on the page do I see the price. So hard to tell if they actually get paid ;)
