Sofi is a platform that allows you to invest with 0% management fees and access to financial advisors.
InvestUsers make money via stock price returns and dividends with 0% management fees.
Sofi makes money through interest through an FDIC sweep program (due to uninvested cash held within accounts), lending securities to institutions that need to borrow shares, and rebates through their clearing firm, Apex Partners, using a payment-for-oder-flow process.
With investing comes risk including the possible loss of principal and there is no assurance that the investment will provide positive performance over any period of time.
