alt Hacker NewsI think you are underestimating how many product problems at big companies are actually bad technical debt. They cant release new features or evolve the offering because the systems are too complicated to change. 1 year of quick development could stunt the whole org for the next five years.
The good news if you take 2 years to ship the system "properly" then you won't have to re-factor it because the company went out of business or that product was too late to market.
There is a phrase "million dollar problems". You do stuff at your startup that will take a million dollars to fix because it doesn't scale.
The point is that if your startup doesn't get to that scale then it doesn't matter. If you startup does reach that scale then you have plenty of money/people to spend a million dollars fixing it.
