You can’t hire salespeople because you think I have some basic stuff, let me start selling this now.
You can’t sell half a car. If you are trying to build a car, don’t try to say, see, half the car is built, the other half will get built too.
If you are building a cycle you can. do that, you can sell a two-wheel cycle. But if you are building a car, you have to in your head know what your least viable product is, what your product looks like.
