So if I try to apply the advice Sam Altman gave in his lectures, I'd suggest you to be careful in finding a cofounder. If you don't already know somebody, any choice is very likely to be a bad choice.
You probably already put a few thousands of dollars into the product. Any cofounder/partner would have to bring a substantial benefit to the table, probably unlike anything a first-time cofounder with little experience could give to you.
My advice would be to look to an active investor, a business angel maybe. Such a person would either have experience and contacts to develop the business side or the software/hardware side.
Having no cofounder isn't that big of a catastrophe, because it is unlikely you will quickly find someone who is highly qualified, willing to take the risk and is as passionate about the product as you (hopefully) are.
