How it works
From scattered receipts to a clean decision queue.

Connect or forward
Connect your expense feed or forward SaaS email receipts into one private inbox.
Reveal the stack
AI flags each recurring SaaS charge, matches the vendor, and identifies who bought it.
Approve what stays
Review one clear queue and confirm the tools your team still needs.
Cancel and prevent
Cancel dead subscriptions in one click, while renewal alerts block the next surprise auto-renewal.
Why not the incumbents?

Questions
Before you connect anything.
How does ShadowStack find subscriptions without IT access?
It matches recurring patterns across expense transactions and forwarded email receipts. Vendor, amount, cadence, purchaser, and renewal signals are combined into one review queue—without requiring SSO or an IT directory integration.
What happens when I cancel?
Where a vendor supports an automated path, ShadowStack handles the cancellation flow. Otherwise, it hands you the vendor’s direct cancellation link and the context you need to finish quickly.
Is my financial data safe?
The private pilot is designed around read-only financial access. Data is encrypted in transit and at rest, and ShadowStack does not need permission to move money or change your expense records.
How is this different from Nudge Security or Zluri?
ShadowStack starts with spend and action, not enterprise security governance or a long implementation. It is built for smaller SaaS companies that want expense-based discovery and a faster path to cancellation.
When does the private pilot start?
Pilot access opens in small cohorts. Join the waitlist and we’ll confirm fit, timing, and the tier that matches your team size.
