Interesting read, I'm surprised nobody has brought up Pejman Nozad who is the owner of one of the more popular rug shops. https://pear.vc/team/pejman-nozad/

His money doesn't come from the rug shops. He sells rugs, but the rug shop was where he used to meet investors and founders and make investments. I assume the rug shop in Menlo Park has a similar background.
