Our take
SoFi started by offering ways for students to secure better financial terms on their loans, and now offers a huge range of personal finance products, including bank accounts, loans, mortgages, investment advice, and investment opportunities. Many customers find they have to go to multiple financial service providers to meet all their finance needs, but SoFi overcomes this issue by putting it all in one place.
Its goal, to cover all the financial bases, sets it apart from many of the traditional banks and even some of their digital competitors, such as Avant, which has chosen to focus on providing credit alternatives. Although it is operating in a competitive market with a lot of big players such as Monzo, Revolut, and Starling, the company has managed to raise huge amounts of funding to support its rapid expansion.
SoFi has focussed on global expansion, moving outside the US, and has made a series of acquisitions to support this - including a Hong Kong-based investment app called 8 Securities. After going public on the New York Stock Exchange via a SPAC merger in June 2021, the company has continued to evolve and release more mission-oriented services into its roster and has strengthened its lending capabilities through a $350 million post-IPO loan. To date, the company has funded over $117 billion in loans and continues to strengthen its offering.
