If you are a non-US citizen: yes.
If you are a US citizen: Possibly yes but only if you are what the Security and Exchange Commission (SEC) calls a sophisticated investor. EmeraMed LLC is not a publicly traded stock and as a result it is not on any stock exchange in the world. A Sophisticated Investor is a classification of investor indicating someone who has sufficient capital, experience and net worth to engage in more advanced types of investment opportunities. For those selling stocks in companies that are not publicly traded the SEC is concerned about scammers taking the unsophisticated investors money. To prevent that they limit how many and who can invest.
