Yes, I have successful experience in both hardware and software projects. The cost of hardware projects in the early sample design stage is controllable. The most expensive stage is the mass production stage, industrial molds and mass production costs. But my previous hardware projects will be pre-sold and crowdfunded after the samples are out. Pre-sales and crowdfunding can recover our mass production costs and profits, but the premise is that we have created hardware products that users like. For software projects, although the initial investment is small, it takes a long time, so the cost of trial and error in the early stage of hardware and software is very high. I like this kind of challenge.
