I guess it would be better to change "founded" to "founded or cofounded". Your formulation is fine too, although immigrants are Americans, so I don't love that

I guess it would be better to change "founded" to "founded or cofounded". Your formulation is fine too, although immigrants are Americans, so I don't love that distinction. Regardless, these all conjure up the same idea for me. For the purposes of this discussion, I don't even see much difference between founder and cofounder. Typically if someone is called a cofounder then the business probably wouldn't exist without them. To settle the argument, why don't we agree to stick with this sentence from the original study: "43 percent of these companies were founded or co-founded by an immigrant or the child of an immigrant."
