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.

1

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.

2

Identify overlaps

The evaluation computes which tools duplicate each other, capability by capability, and the Utilization lens shows seats bought against seats used. See which tools serve the same function and which are critical path.

3

Analyze cost impact

The Cost lens shows what each tool costs per month. The evaluation puts a recoverable-spend range on the overlaps, from the costs you enter, or category benchmarks where you have not entered one.

4

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 canvas, next to the evaluation, they are hard to miss. Filter by category, trace data flows, and identify which tools are truly redundant.

  • See which tools share capabilities
  • Trace data flow to understand dependencies
  • Identify critical-path vs. redundant tools
  • Filter the canvas by category
The Instant Stack Audit's overlap map: ten tools in a ring, red lines joining the pairs that overlap (Braze, Iterable, Klaviyo and Mailchimp; Segment, mParticle and Hightouch), bubble size by annual spend

Computed Redundancy Detection

The evaluation compares every pair of tools against a capability taxonomy of 134 capabilities and a stored verdict on each vendor pair, so a complement is not counted as waste. It names the overlaps, grades the stack A–F and gives a keep, evaluate or remove call per tool. The AI explains the findings; it does not produce them.

  • Specific consolidation recommendations
  • Single points of failure and orphaned tools
  • Recoverable spend, as a range

Cost Lens and Stack Costs

Switch to the Cost lens to see what each tool costs per month, right on the diagram. On Consultant, Agency, Team and Enterprise, the Stack Costs panel adds spend by department, a renewal calendar and a forecast. Build a business case with the numbers you entered.

  • Monthly cost on every tool
  • Recoverable spend from the overlaps
  • Renewals and forecast in Stack Costs
  • Data for budget conversations
Stack Costs: tracked spend per year, seat utilisation, recoverable spend, spend by department and each vendor's contract, seats and renewal date

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. Name an owner and a date for each

    An unowned consolidation is a wish. One name, one date, one success measure per cut.

Worked example Illustrative

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: The stack evaluation computes step 2 from the capability taxonomy rather than a workshop, and prices each overlap from the costs you have entered.

Frequently Asked Questions

How does Stack Builder help with consolidation?
It gives you three things spreadsheets can't: a visual map showing how tools connect, an evaluation that computes which tools duplicate each other and grades the stack A–F, and lens views that show cost and data flow before you make changes.
Can AI identify which tools to cut?
The engine identifies them, not the AI: it compares tools capability by capability, checks each pair against a stored verdict so complements are not counted as waste, and gives a keep/evaluate/remove call per tool. The AI explains those findings. The final decision should still involve your team. Some "redundant" tools serve different teams or use cases that aren't obvious from architecture alone.
What if we cut a tool and something breaks?
That's exactly why visual mapping matters. Trace Data Flow shows every upstream and downstream dependency before you remove anything. You'll see exactly what's connected before making changes.
How do I get buy-in from leadership?
Export the evaluation report as a PDF. The grade, the named overlaps and the recoverable spend give leadership a clear picture of why consolidation is needed and where to start.
How long does a consolidation analysis take?
Building your initial stack map takes 15-30 minutes. The evaluation is computed in seconds. Most teams complete their full consolidation analysis in a single afternoon.
Can we track consolidation progress over time?
Save checkpoints at each stage. Compare your stack before and after consolidation to measure progress and demonstrate ROI.
Is there a free plan?
Yes. The instant audit needs no account, and the free plan saves up to 3 stacks. Pro ($39/month) adds a monthly AI allowance with top-ups, all lens views and 20 cloud saves. The Stack Costs panel (per-tool costs, renewals, forecast) is on Consultant, Agency, Team and Enterprise.
