Σ  SIGMASTACK · CYBER SECURITY

Find the software you're paying for twice.

Every team buys its own tools. A few years later the enterprise runs three whiteboards, two office suites, and a video platform nobody has opened since 2024 — and every unmanaged app is spend, attack surface, and audit debt. SigmaSTACK discovers the whole portfolio, detects functional overlap with evidence you can check, and drives consolidation to closure. Then its pre-purchase gate stops the next duplicate before the PO is cut.

The problem

Software sprawl isn't an inventory problem. It's an overlap problem.

Inventory tools can tell you that you own 400 apps. They can't tell you that eleven of them are, functionally, the same four products — or that the marketing team is about to buy a twelfth. Redundancy hides because apps have different names, different vendors, and different owners, while quietly doing the same job for the same people on the same data. Industry benchmarks put 10–30% of SaaS spend in that shadow. Finding it takes more than name-matching; retiring it takes evidence strong enough to survive the app owner's objections.

How it works

Five signals. One explainable score.

Two apps overlap because they do the same things for the same people — not because their names look alike. SigmaSTACK measures five independent signals and fuses them into a 0–100 score with the evidence attached.

Capability match Shared active users Workflow position Data domains Integrations 82 OVERLAP + evidence + gaps → Tolerate · Invest Migrate · Eliminate
01

Capability match — 34%

A 66-capability functional taxonomy describes what each app actually does. Overlap starts from function, not from name similarity.

02

Shared active users — 28%

People active in both apps within 30 days. What teams do outweighs what the catalog says.

03

Workflow position — 16%

Same functional category, same slot in how work flows through the organization.

04

Data domains — 12%

Apps handling the same classes of data (customer PII, contracts, telemetry) compound cost and risk.

05

Integrations — 10%

Two tools wired into the same systems usually occupy the same seat at the table.

Σ

Feasibility, not just overlap

Capability gaps and regulatory constraints are surfaced with every score. 80% overlap where the missing 20% is a compliance requirement is not an opportunity — and SigmaSTACK says so.

One estate, one number that matters. Redundant spend is counted per app — never per overlap pair — so the savings figure survives CFO scrutiny.

Why SigmaSTACK

Built for the decision, not just the inventory

Most tools stop at a list of what you own. SigmaSTACK is built for what happens next: proving the overlap, winning the argument, and closing the savings.

Five-signal overlap engine

Capability, shared users, workflow, data domains, integrations — fused into one explainable score. Never name-matching.

Pre-purchase gate

Every new software request is matched against the live portfolio before approval: "You already own Miro — 31% utilized, 138 seats free."

TIME board with reasons

Tolerate / Invest / Migrate / Eliminate, decided by auditable rules — each classification lists exactly why, line by line.

Behavioral usage truth

Utilization from who's actually active in the last 30 days — per app, per department — not from license counts.

Renewal runway

Every contract with its notice-by deadline — because an overlap confirmed the week after auto-renewal is worth nothing for a year.

Shadow IT from spend

Drop in an AP/expense export; vendors with no sanctioned record surface instantly as flagged findings with their annual cost attached.

Audit-ready by default

Append-only trail of every decision with actor and reasoning; CSV exports carry the evidence so any number can be re-checked.

Feasibility, stated plainly

Capability gaps and regulatory constraints ride with every recommendation. The tool never proposes retiring what compliance depends on without saying so.

Five roles, unlimited users

Admin, analyst, app owner, finance, auditor — deny-by-default access with field-level rights. Invite the whole organization at no extra cost.

The opening

Rationalization keeps failing. Here's why we'll win.

SAM suites inventory well and decide poorly. Spend dashboards find waste and can't prove overlap. We built SigmaSTACK for the part everyone skips: the evidence that survives the meeting.

What buyers reportSigmaSTACK's answer
"Inventory tools list apps; they can't see overlap"Five-signal engine scores functional overlap with evidence, not name similarity
"Recommendations are black boxes nobody trusts"Every score decomposes into signals + facts a human can verify
"Projected savings evaporate under scrutiny"Per-app savings math, feasibility gaps and regulatory blockers stated up front
"We cleaned up last year; it grew back"The pre-purchase gate stops new redundancy before the PO
"Priced per employee — the tool costs like the problem"Priced by apps under management, unlimited users on every tier
"Deployment took two quarters"SSO connect + one expense CSV → first findings in under an hour

Typical customers identify 10–30% of SaaS spend as addressable in the first 30 days — the platform usually pays for itself with its first confirmed overlap.
