$1.1M vs $4.2M
Archipelago Software platform — 16 production SaaS products, same scope, outcome contract
73%
of code AI-written on the Archipelago engagement — 100% human-reviewed against the quality checks
8–14 wks
typical delivery for a custom software build, compared to 9–18 months on a Big-4 quote
5 gates
on every pull request before a human sees the diff — spec coverage, test, security, performance, trace
Why the price gap exists
AI is writing 60–70% of the code. The cost has dropped to 10% of the 2023 rate card. Who keeps the difference is the question.
A firm that bills on day rates keeps the AI productivity gain. When AI writes 70% of the code, the day-rate firm's costs drop but the invoice doesn't change. The client pays for the hours that used to be needed.
An outcome contract prices the scope, not the hours. When AI writes 70% of the code on an outcome-priced engagement, the saving flows to the client. The Archipelago Software platform — 16 production SaaS products — came in at $1.1M against a $4.2M Big-4 quote. 73% AI-written, 100% human-reviewed. The framework that built it is the same one we bring to every new engagement.
The same scope, three delivery shapes
How the numbers compare.
| Dimension | Effektiv build | Big-4 fixed-price | Day-rate firm |
|---|---|---|---|
| Typical 12-week project | $160k–$420k all-in | $420k–$1.1M | $280k–$540k |
| AI authorship disclosed | Per PR, in the trace | Aggregate at end | Not produced |
| Code ownership at exit | Yours, in your repo | Vendor-retained until escrow trigger | Mixed; depends on contract |
| Eval rig handoff | Source code yours at exit | Vendor-framework retained | Not produced |
How we deliver
Diagnose. Design. Deliver.
Two weeks of listening before a line of code. The price is fixed at the end of Design — not at kick-off.
Phase 1 · 1–2 weeks
Diagnose
We read your stack, sprint history, and AI controls. We map the governance posture and build an evaluation rig shaped to your system. Output: a findings document and an outcome contract your legal team can read in one sitting.
Phase 2 · 1–2 weeks
Design
A build plan shaped to what Diagnose found, with the outcome metric named. The quality checks is specified here — not delivered as a surprise at exit. The price agreed at the end of Design is the price on the invoice. No scope creep billing.
Phase 3 · 8–14 weeks
Deliver
AI agents author at pace. Senior pair from each side reviews every pull request: spec coverage, test coverage, security scan, performance budget. Human sign-off on architecture, security, and any line that touches money or a record of truth.
Quality gates
What the quality checks measures.
Every output passes a multi-gate evaluation before it merges or ships. Outputs that fail do not proceed. The quality checks and all gate code are yours at exit.
- Spec coverage across the agreed acceptance criteria — threshold 100% before any milestone closes
- Test coverage on AI-authored code — threshold agreed in Design against your existing standard
- Security scan pass on every PR — zero high-severity findings before merge
- Performance budget adherence under load tests — named in Design
- AI authorship trace integrity — every line attributable to a model run with prompt and version
