Spendassay vs. CloudZero
CloudZero maps your cost. Spendassay audits what it bought.
CloudZero is a mature FinOps platform, repositioned in May 2026 around AI ROI. It ingests cloud and AI cost and attributes it to units the business cares about (cost per customer, per feature, per team), so finance and engineering see where the money goes. That attribution is real work, and CloudZero does it across major clouds and AI vendors. Spendassay does a narrower, different job: it audits AI spend specifically against engineering delivery, buyer-side and independent, and attaches a proof level and a visible formula to every dollar. Many teams run a cost platform for the bill and Spendassay for the audit.
The one-line difference
CloudZero tells you what you spent and how to attribute it; Spendassay tells you what that AI spend shipped, and shows its work.
Two jobs, often side by side
Use each for what it's built for
Reach for CloudZero when…
Reach for CloudZero when you need broad cloud and AI cost visibility, unit-economics attribution, and cost-per-customer reporting across your whole infrastructure bill.
Reach for Spendassay when…
Reach for Spendassay when you need an independent, CFO-forwardable audit that ties AI seats and tokens to what engineering actually shipped, with a stated proof level behind every number.
Side by side
Built for different questions
| Dimension | CloudZero | Spendassay |
|---|---|---|
| Primary job | Cloud + AI cost visibility and unit-economics attribution across the whole bill. | Audit AI spend against engineering delivery and produce an AI cost report a CFO can forward. |
| Scope | Broad: cloud infrastructure, Kubernetes, and AI vendor cost in one platform. | Focused: AI seats, API tokens, and AI infra, tied to team output. |
| What it measures | Cost attributed to business units — cost per customer, per feature, per team. | Whether the AI spend shipped software: spend connected to shipped engineering work. |
| Independence | Cost-platform vendor; you connect your accounts and it reports on spend. | Buyer-side auditor. Issues no cards and resells no tools. Read-only, metadata-only. |
| Evidence on every number | Attribution and allocation across cost sources. | Every dollar carries a proof level (Counted > Compared > Estimated) and exposes its formula. |
| How you buy | Sales-led. Book a demo; pricing is a custom quote. | Free self-serve Snapshot; published pricing (Observe $16/eng-mo, Control $40/eng-mo). |
| Pricing | No public price. Sales-led, tiered on annualized cloud spend under management; cloudzero.com/pricing is a request form. | Published and self-serve: a free Snapshot, then $16 per covered engineer per month (Observe) and $40 (Control). Priced per engineer, never as a percentage of your AI spend. |

Common questions
Spendassay and CloudZero
- Is CloudZero a competitor to Spendassay?
- They overlap but do different jobs. CloudZero is a cloud + AI FinOps platform built for broad cost visibility and unit-economics attribution. Spendassay is a focused, independent audit that ties AI spend to shipped engineering output with a proof level on every number. Teams often run a cost platform and Spendassay side by side.
- Can I use both?
- Yes, and many do. A cost platform like CloudZero tells you what you spent and how to attribute it across the business. Spendassay sits downstream and asks whether the AI spend shipped software, then packages that as a CFO-forwardable audit. The cost data and the audit answer different questions.
- Does Spendassay do what CloudZero does?
- No. Spendassay does not aim to be a full cloud cost platform — it does not report your whole AWS or Kubernetes bill. It audits AI spend specifically, connects it to engineering delivery, and shows the formula and proof level behind each finding. If you need broad infrastructure cost attribution, use a FinOps platform; if you need an independent AI-spend audit, use Spendassay.
