Bootstrapping is a marathon, not a sprint. Bootstrapping is kind of like stacking bricks, except you mught be making each brick too.

Sometimes you have to build the first thing to get to the second thing.

Before developing hardware, I'd see if there's a lucrative software based problem in this area that could be bootstrapped to generate revenue to fund the next project.

In a way SpaceX is doing their equivalent of this by building Starlink to generate ongoing monthly revenue that conceivably could be directed elsewhere.
