As an analogy, say I had the idea for a car when everyone is still using horses. I raised a seed round to build my car but the funding is only enough to build a car prototype that goes 10mph. At 10mph, there is obviously no product/market fit since horses are still faster and cheaper. However, the prototype proved out the technical challenges, so I know with more capital I'd be able to make a car that can go 80mph, making the horses obsolete. How would your post apply in this case?
