Where was Kesem started?

Could you please elaborate on the origins of Kesem? Specifically, where was it initially founded? I'm interested in understanding the geographical location that served as the birthplace of this organization or company. It would be helpful to know if there were any particular factors or motivations that led to its establishment in that specific place. Additionally, I'm curious about the initial vision and goals that the founders had in mind when they set out to create Kesem.
