The question has been also on our mind. We restructure now towards a https://steward-ownership.com/ company structure (in CH). The hard challenge will be fundraising - so we are actually considering selling "Partizipationsscheine" which are stocks without a vote, but still a dividend. On a open market (maybe through polygon / base coins). I just wonder how to resolve the initial funding question on those companies. Any ideas?

Don't think you need anything like polygon or tokens for this. I think you just have to have the courage to ask investors to play the proper role within the governance of your company and, frankly, have the business results such that they are willing to accept those terms.
