Have you considered slashing features in order to speed up your MVP release? Our own "must have" features are often not must haves for users. I was in the same boat a few years back and released a cut down version missing what I thought were must have features. Many years and 1,000+ users later no one has ever requested the missing "key features."

I have the same issue as him but the issue is that users today expect a certain level of fidelity otherwise they will stick to incumbents.

I think your advice worked back in 2010-2018 when the bar was very low.

My audience literally didn’t want to use my product because while it was solving their problem it didn’t have the same level of fidelity as their current stack. So I had to spend a lot of time improving it.

These days the bar is so high. Unless you really do find something unique that has not been technified.

These days it’s mostly a David vs Goliath style of battle.
