Our take
Founded in 2015, Stash was created in response to studies showing that 44% of Americans don’t invest in stocks, 70% of households don’t have a long-term financial plan, and 68% are afraid to retire. Stash offers beginner retail investors the tools to invest small amounts in stocks and exchange-traded funds. It aims to help new investors learn the ropes, offering preference-tailored guidance and digestible investment summaries.
Its service, although pricier than competitors like Wealthfront and Acorns, remains competitive through its highly educational and beginner-friendly focus. This is a lucrative feature for Stash, given the recent surge in first-time and amateur retail investors. The company has more than 6 million customers, and its assets under management total about $3 billion.
Its focus on long-term profit over day trading is refreshing in the retail investment app market. It could prove especially attractive to its younger customer base (average age 29), who are on the whole trending away from traditional legacy banking and looking towards new, innovative financial platforms.
Stash was not immune to the market turmoil of 2022, which particularly impacted the fintech sector, and was forced to restructure. Having streamlined the business, it received major funding and a leadership change in 2023. Stash is now setting its sights on an acquisition or public offering in the near future.
