About StackSentry

StackSentry helps marketing, creative, and development agencies understand what they spend on software—and where that spend no longer supports active work.

Agencies have a particular kind of software sprawl: tools added for one client, seats kept after teams change, and overlapping platforms owned by different departments. Generic spend reports miss that context. StackSentry is designed around it.

We begin with an outcomes-based audit, then offer ongoing monitoring for agencies that want to catch seat creep and renewals before they become another year of unnecessary spend.
