My friends and I have a seed-investment fund that we needed to be low overhead since we're all running companies. The Delaware process was fairly low-overhead. Some things needed to be notarized and it was a pretty easy process to get a virtual mailbox and everything (notarize.com was in the loop and they're neat!)
Sorry it isn't directly against your constraints but we are foreigners in the US so I thought I'd mention it. More information is always better :)
So basically you are a group of non US citizens living in the US and wanted to have a shared entity to do investments? Well I guess then a Delaware C Corp is the logical solution? Did you use Stripe Atlas to set it up?
Yes, right on the money. Though there's a slight natural difference for us to accommodate later participants. Yeah, we used Stripe Atlas, though none of the startups we run are through that. Overall, quite painless to be honest.
Actually, I just checked our Stripe Atlas. Originally intended the C corp so we could bring people in but we were instead advised to just start a new LLC each time if we wanted and that we could have one LLC just be the owner of the other.
So I should correct this. We did end up with an LLC but the C corp would have worked just fine apparently.

Good luck! Eager to hear how it goes.
