Member portal
Responsive online banking with multi factor authentication and session controls.

The member portal, the banker console and the ledger run on one platform, with encryption, audit logging and a security program that is reviewed continuously.
Technology
River Gem runs a cloud native banking platform with hosted authentication, a PostgreSQL ledger and object storage for documents. The design goal is simple: every money movement has an owner, a timestamp and a resulting balance.

We do not claim a certification we have not earned. Where a control is still maturing, the risk register says so and the board sees it. Security is a program, not a badge.

Most personal applications take about eight minutes. You will get a decision, a routing number for DFAS and a named banker not a waiting list.
