Stack Consolidation
Cut the Right Tools. Keep the Ones That Matter.
Everyone knows you have too many tools. The hard part is proving which ones to cut without breaking something. See overlaps, trace dependencies, quantify savings — and make consolidation decisions your CFO and your engineers can both support.
No signup needed — tick your tools, see overlaps and recoverable spend instantly.
The consolidation imperative
The numbers tell the story. Stack sprawl has hit a tipping point.

Stack sprawl is the defining Martech challenge of 2026. Budgets are tightening, tools overlap, and nobody can confidently answer 'what would break if we removed this tool?' Stack Builder helps you move from gut feeling to data-driven consolidation.
Four steps to confident consolidation
A structured workflow to go from stack chaos to a clear consolidation plan.
Map your complete stack
Build a visual inventory of every tool, how they connect, and what data flows between them. See the full picture before making any cuts.
Identify overlaps with AI
AI evaluation highlights redundant capabilities, underutilized tools, and integration gaps. See which tools serve the same function and which are critical path.
Analyze cost impact
The Cost Analysis lens shows spend distribution across your stack. Identify your most expensive redundancies and quantify potential savings.
Build your consolidation plan
Use multi-lens views to understand the full impact of removing a tool — data flow disruption, team dependencies, and cost savings. Export your plan for stakeholder approval.
Purpose-built for stack consolidation
Tools that turn consolidation from a political minefield into a data-driven process.
Visualize Tool Overlaps
When multiple tools serve the same function, it's hard to see in a spreadsheet. On a visual canvas, overlapping capabilities become immediately obvious. Group tools by category, trace data flows, and identify which tools are truly redundant.
- See category overlaps at a glance
- Trace data flow to understand dependencies
- Identify critical-path vs. redundant tools
- Group by function for clarity
AI-Powered Redundancy Detection
The AI evaluation doesn't just grade your stack — it identifies specific redundancies and optimization opportunities. Get recommendations for which tools to consolidate and why.
- Automatic redundancy identification
- Specific consolidation recommendations
- Integration health assessment
- Cost efficiency scoring
Cost Analysis Lens
Switch to the Cost lens to see exactly where your budget goes. Visualize spend per tool, per category, and identify the biggest cost-saving opportunities. Build a business case with real numbers.
- Visualize spend distribution
- Quantify consolidation savings
- Category-level cost analysis
- Data for budget conversations
The method
Build the consolidation case by hand
Consolidation fails when it is argued as tidiness. It succeeds when each cut has a named owner, a migration cost and a date. Allow a day, most of it spent on step 3.
-
Group tools by the job they do
Not by vendor category — by the outcome someone needs. Anything with more than one tool in a group is a consolidation candidate.
-
List the capabilities each tool in a group actually provides
Tick the capabilities each one covers. The overlap is the intersection; the risk is what only the tool you plan to cut can do. That column is the one that kills naive consolidations, so fill it in honestly.
-
Price the migration, not just the licence
For each candidate cut: licence saved, minus rebuild effort, integration rework, retraining, and the contract you cannot exit until renewal. A cut that saves $2k a month and costs six weeks of engineering is not a cut this year.
-
Sequence by renewal date
Order the surviving candidates by contract end. Consolidation is a calendar problem — the best case you cannot act on for eleven months goes below the mediocre one renewing in six weeks.
-
Name an owner and a date for each
An unowned consolidation is a wish. One name, one date, one success measure per cut.
Retail stack, two email platforms and two analytics tools in overlapping groups.
| Capability overlap, email pair | 68% |
|---|---|
| Only on the tool being cut | 2 capabilities |
| Combined licence | $4,200/mo |
| Estimated recoverable | $1,900/mo |
| Migration effort | ~4 weeks |
| Earliest exit | renewal in 5 months |
Reading it: A 68% overlap looks decisive until the 2 unique capabilities are named and the exit date is five months out. This is a real cut, but it is next-half work with a rebuild attached — not a quick win.
The shortcut: Stack DNA computes step 2 from the capability taxonomy rather than a workshop, and prices the group from your cost data.
