Ironically, quality is the enemy of a startup. You can only do quality once you've got Product Market Fit (very very subjective thing, i understand). The analogy is building a quality, beautiful hotel on Antarctica - it's effectively useless and no one will pay you money you need for it to survive.

Oversimplification is, test, test, test until something sticks. Once something sticks optimize it with quality.

So initially, yes, you need faster, faster, faster.
