Trading MainStreet Stock
How to invest in MainStreet stock?
Accredited investors can buy pre-IPO stock in companies like MainStreet through EquityZen funds. These investments are made available by existing MainStreet 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.

If I invest, how do I exit my investment?
There are two ways to exit your private company investment on EquityZen's marketplace. The first is if the company has an exit event like an IPO, merger or acquisition. In that case, we will distribute the shares and/or cash to you directly. The second way is through an Express Deal on EquityZen, if eligible. An Express Deal allows you to sell your allocation of private shares in a given private company to another investor on EquityZen's marketplace. More information on Express Deals can be found here and exit information can be found here.
