Case in point of “engineers are not product people”
Back in the day, here is Sokovia, there was a local competetitor to Facebook. They had a great start and everything went perfect for them, but it quickly turned out that the technical side was really bad. Sluggish interface, constant outages, etc.
They tried to rewrite the app from scratch two times, and eventually failed.
So yes, making sure you're moving in the right direction at the beginning of your journey is pretty important. You don't have to overengineer and stay in your shed until you have a complete, feature complete product, but at least make sure, that you're building on the right foundation.
Just understand and accept that you are taking on heavy technical debt that will need to be repaid, and that it’s much more difficult to do once you’ve already vertically scaled several times along the way.
