Spendassay vs. Jellyfish
Jellyfish measures engineering output. Spendassay prices it against spend.
Jellyfish is a software engineering intelligence and AI impact platform, which is how it describes itself as of 2026. It pulls data from your developer tools to show R&D leaders how work moves: delivery, allocation, AI adoption, and developer experience. It now reports AI usage and cost inside that picture. That is a real and valuable job. Spendassay does a different one. It is an independent, cross-vendor auditor that connects every dollar of AI spend to what teams actually shipped, and it attaches a proof level and a visible formula to each number. Many teams run both.
The one-line difference
Jellyfish tells you how your engineering org is performing; Spendassay tells you what each AI dollar bought, with the formula shown.

Use each for what it's built for
Reach for Jellyfish when…
Reach for Jellyfish when you want a standing view of R&D productivity, delivery flow, resource allocation, and developer experience across the software lifecycle, plus finance features like software capitalization.
Reach for Spendassay when…
Reach for Spendassay when finance needs a defensible AI cost report: the full AI bill across every vendor priced against shipped output, each dollar tagged counted, compared, or estimated, and forwardable to a CFO.
Side by side
Built for different questions
| Dimension | Jellyfish | Spendassay |
|---|---|---|
| Primary job | Software engineering intelligence — a standing view of R&D output and flow | An independent audit that prices AI spend against shipped output |
| What it measures | Delivery, allocation, developer experience, and AI adoption, with AI cost reported inside the platform | The whole AI bill (seats, API tokens, infra) mapped to what teams shipped |
| Connects spend to shipped output | Reports AI cost and productivity side by side within the platform | Produces a per-dollar AI cost report: spend priced against output, cost per unit shipped |
| Independence | An engineering-intelligence platform reading your dev-tool stack | A cross-vendor auditor, tied to no tool it is measuring |
| Evidence on every number | Insights and benchmarks from aggregated tool data | Each dollar carries a proof level (Counted > Compared > Estimated) and exposes its formula |
| How you buy | Request a demo; pricing is quoted by sales | Free self-serve Snapshot; published pricing (Observe $16/eng-mo, Control $40/eng-mo) |
| Pricing | No public price. Sales-led, with no self-serve tier and no public trial. | 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 Jellyfish
- Is Jellyfish a competitor to Spendassay?
- They overlap at the edges but do different jobs. Jellyfish is a software engineering intelligence platform built to show R&D leaders how work moves: delivery, allocation, AI adoption, and developer experience. Spendassay is an independent auditor built to price your AI spend against what teams shipped, with a proof level on every dollar. Jellyfish reports AI cost as one part of a productivity picture; Spendassay's entire job is the cross-vendor AI cost report.
- Can I use both?
- Yes, and many teams do. Jellyfish gives engineering leaders an ongoing read on output and flow. Spendassay gives finance a defensible per-dollar view of the AI bill across every vendor, forwardable to a CFO. One measures performance; the other prices it against spend.
- Does Spendassay do what Jellyfish does?
- No. Spendassay does not track delivery flow, developer experience, resource allocation across the lifecycle, or R&D finance features like software capitalization. It stays on one question: what did each AI dollar buy. It is read-only and metadata-only, never ingests code or prompts, and reports at the team level rather than ranking individuals.
