Ask HN: Have you started a company that has zero to do with software?

I just discovered Shark Tank for the first time (I know I'm behind the times, but alas). I get really inspired/energized by the businesses people are out there working on - specifically, that the majority have nothing to do with software.

Assuming the majority of HN works in tech, have you started a business that wasn't within the software realm? What did you create?
