To be frank, in order to maintain a business, you can't just do all the things alone. So it's really common to have more than one person as the founders of a company. The idea is, it's better to have at least one partner who is growing the same direction as yours. So a technical person would be the best candidate, i would say.
That's what I thought too - that's why I am just curious if there is any great example that founded only by one designer founder, though I totally understand the importance of having a co-founder with strong technical background.
