Trading Membrion Stock
How to invest in Membrion stock?
Accredited investors can buy pre-IPO stock in companies like Membrion through EquityZen funds. These investments are made available by existing Membrion shareholders who sell their shares on our platform. Typically, these are early employees who need to fund a life event – house, education, etc. Accredited investors are then offered the opportunity to invest in this stock through a fund, like those used by hedge funds serving large investors. While not without risk, investing in private companies can help investors reach goals of portfolio diversification, access to potential growth and high potential return.
