StackSwap vs Zylo
Updated Apr 17, 2026
Zylo and StackSwap sound like competitors. They are not, and picking the wrong one is the single most common SaaS management mistake.
Zylo is a SaaS management platform (SMP). It ingests SSO logs, finance feeds, and expense systems to discover every tool your company pays for, then tracks license usage and renewal dates. Built for IT and procurement.
StackSwap is a GTM stack audit tool. It takes the tools you already know about, scores them against peer stacks, names specific replacements, and models savings. Built for RevOps, sales leadership, and GTM finance.
Criteria comparison
| Criterion | Zylo | StackSwap |
|---|---|---|
| Primary buyer | IT, Procurement | RevOps, GTM Finance |
| Discovery source | SSO + finance feeds | User-declared stack |
| Answers "what do we own?" | Best | No |
| Answers "what should we stop owning?" | Weak | Best |
| License usage tracking | Yes | No |
| Named replacements | No | Yes |
| Modeled savings by team size | No | Yes |
| Time to first useful output | Days (integrations) | Seconds (scan) |
| Good for shadow IT | Best | No |
| Good for renewal decisions | Partial | Best |
When Zylo wins
- You suspect shadow SaaS and need discovery across 100+ vendors.
- IT is the sponsor and the consolidation goal is governance, not cost.
- You have the time and integration budget for a multi-week onboarding.
When StackSwap wins
- You already know your GTM stack and need a consolidation plan before renewal.
- The sponsor is RevOps, sales leadership, or finance.
- You want named replacements ("move from HubSpot to Attio") not capability overlap maps.
- You need a defensible output for a CFO conversation this week.
Running them together
Most mature GTM orgs run both. Zylo or a similar SMP handles discovery and license hygiene across the whole company. StackSwap handles GTM-specific consolidation plans. The feeds are different; the decisions are different.
Takeaway
If the ask is "what are we paying for?" — pick Zylo. If the ask is "what should we consolidate before the next renewal?" — pick StackSwap. Confusing them wastes a quarter.
