What problem does a real estate portfolio bookkeeping/aggregation tool actually solve, and who is it built for?

The tool aggregates data across many bank accounts, loans, leases, and property management reports into one place — in the example given, 21 bank accounts across five banks plus reports from four different property managers. Anyone could use it as a general bookkeeping and financial management tool, but it's specifically built to solve the pain of investors and operators who hold many different types of real estate investments and otherwise have to pull together data from disparate, non-standardized sources.
