Acorns has made micro investing possible through its proprietary investment platform. The brokerage and advisory functions are operated algorithmically while the proprietary back-end technologies aggregate order-processing and clearing functions, repopulating data via the cloud. Acorns works with external developers who wish to use the platform to transform rewards programs into investable cash. The app can also help identify and gather found money, such as rebates and rewards, which can be automatically swept into the customer’s investment account.
