Northbridge Capital: A client portal that turned quarterly reporting into a same-day process.
Northbridge's reporting process relied on spreadsheets passed between teams, taking weeks to compile and leaving room for error at every handoff. We built a client portal that pulls data directly from source systems, giving both staff and clients a single, always-current view of portfolio performance.
Quarterly reports that took two weeks now take a single afternoon, with fewer errors and faster client sign-off.
