Contractually binding

The 3× ROI Guarantee.

If CARTIE doesn't save you 3× your subscription fee in your first 90 days, you get a full refund. No clawbacks. No fine print. In writing.

SCOPE TODAY: Engine #27 (AI token savings) — guarantee active. Cloud-side guarantee ships with the Code Tracer · Q2 2026.

How the math actually works.

Most FinOps tools claim savings they can't prove. We attribute every dollar to a specific engine, a specific incident, and a specific code change you can audit.

1
We measure realized savings — not theoretical.
Every booking is tied to a real action: a merged PR, a deleted resource, a re-sized instance, or a cached LLM call. We don't count 'recommendations'. We count merged fixes that show up in your next bill.
2
The clock starts the day your data lands.
Day 0 = the day our connector successfully ingests your first AWS/GCP/Azure bill. Not your contract signature. Not your kickoff call.
3
3× means 3× — on the cumulative subscription you've paid by day 90.
If you've paid $9,000 in subscription fees over 90 days, we need to book ≥ $27,000 in realized savings by that date. The dashboard ticks live so you (and your CFO) always know where you stand.
4
If we miss, you tell us and we refund. Full stop.
No 'extension period', no 'let us try harder', no clawing back free months. You email Harinathmekala@cartieai.com on day 91. We refund within 5 business days.

Why we can offer something this strong.

Because the 27-engine portfolio actually closes the loop — it doesn't stop at dashboards.

Trace
Trace → loop closes.
Cost spikes get mapped back to the exact line of code (or terraform block, or LLM call site) that caused them.
Fix
Fix → loop closes.
The fix ships as a GitHub PR — reviewable, mergeable, auditable. Your engineers stay in their existing workflow.
Book
Book → loop closes.
After merge, we watch the next 30 days of billing and credit the realized savings to the incident. CFO has the receipts.
Auto-cut
Runtime savings, day 1.
Engine #27's Auto-Compiler Proxy reduces AI token spend at runtime — savings flow in even before your team merges the first PR.

What the guarantee doesn't cover. (Honest list.)

We'd rather tell you upfront than fight over it in 90 days.

  • Reservations & commit purchases (we can recommend them, but you have to actually sign the AWS/GCP contract — that's on you).
  • Workloads you explicitly mark "do not optimize" (some teams want zero autonomy in prod — fine, but those savings don't count toward 3×).
  • Acts of cloud (AWS surprise outage, GCP price re-jig, an OpenAI rate-limit change). We re-baseline and the clock resets.
  • Refunds are pro-rated for legitimately consumed services if you cancel mid-period; the guarantee math is over the full 90 days.

Want it in writing first?

We'll send the full Master Services Agreement with the 3× ROI clause boxed and highlighted before you sign anything. No friction, no "contact sales" gating — just email and we send it the same day.
