Everything you need to make a better software decision
Build a centralized view of applications, subscriptions, owners, and costs.
See verified usage where reliable evidence exists—and know when it doesn't.
Surface unused licenses, overlapping tools, renewal opportunities, and other areas that deserve review.
Turn findings into decisions: Keep, Reduce, Renegotiate, Cancel, Replace, or Investigate.
Track actions and their financial impact over time.
Software decisions should be based on evidence—not assumptions.
Stack Sixth distinguishes between what we know, what we can observe, and what we cannot yet verify.
Recent activity has been verified.
Access or a seat has been confirmed, but usage hasn't.
Supporting evidence indicates activity.
We don't have enough evidence to make a usage claim.
A connection doesn't automatically mean usage. And missing data doesn't automatically mean waste.
