Or.... you can look at tweet Jim has put out and narrow down some targets to contact. For instance, "MS Society" or "Mass General" from the 8k, or "ApolloHospitals". There are means and ways of confirming information but it seems like you don't want to do the hard work. Regardless of what people have heard from insiders, it's very easy to reach out to let's say, Fabrizio di Silvestri.
Or even contact past contacts from Jim's last companies.
None of which tells anyone if this venture will be successful, but gives me a read into the type of person I am investing in.
