adviser + co-builder for enterprise AI transformation
Crossing the threshold from AI pilots to production.
Not tool adoption. Not another pilot. Deep integration of AI into how your enterprise operates, delivers, and competes — with explicit evidence for every bet.

Adopting AI is easy. Differentiating with it is not.
New models, providers, harnesses and approaches land faster than any enterprise team can evaluate them. Committees end up choosing on vibes, not evidence — and the decision only gets more expensive to unmake.
PoCs multiply, demos impress the steering committee, nothing reaches production. The gap between "works in a demo" and "works across our business" is where enterprise AI programmes stall.
A Copilot licence changes what people can do. Deep integration into process and delivery changes what the enterprise is. Almost nobody does the second thing well — it takes method, not enthusiasm.
From noise to a decision you can act on.
phase 01 — map

phase 01
Map
Your enterprise workflows and the current AI landscape, surveyed side by side — what is real, what is demo-ware, what deserves a committee's attention.
-
phase 02
Threshold
Explicit evaluation criteria for your use cases: quality, cost, risk, latency, compliance. The bar a technology must clear before your executives are asked to bet on it.
-
phase 03
Cross
Co-built integration — harnesses, workflows, delivery pipelines — until it clears the bar and survives enterprise reality: procurement, security review, scale. Then your team holds the keys.
Advisory when you need judgement. Hands-on when you need it built. Most engagements are both.
"Five years as a Principal Solutions Engineer at Miro — serving Australia's largest enterprises — taught me exactly where enterprise AI breaks: never in the model, always in everything around it."— Ross Johnston, founder, Quethys
Two ways to work together.
-
Advisory
Standing counsel for enterprises navigating AI change: technology and vendor evaluation built for procurement, architecture review, build-versus-buy calls your executives can sign off on — and a methodology your own people can run without me. Retainer or fixed-term.
-
Co-build
Hands-on delivery inside your enterprise: evaluation harnesses, agentic workflows, data and delivery pipelines, internal tooling. Built with your engineers to clear security review, documented for handover, owned by you on day one.
Every engagement starts with a working session, not a sales deck: two hours on your actual problem, and you keep the write-up either way.
Why "Quethys".

from quorum — the threshold at which a group's decision becomes binding. The point where the evidence is strong enough to act on.
and Thetis — the sea goddess who made Achilles invulnerable, everywhere but the heel she held.
Enterprise AI fails the same way: never everywhere, always somewhere specific. Our work is finding the heel before the arrow does — and knowing when the system is strong enough to bet the business on.
Bring us the decision you are stuck on.
If enterprise AI is on your roadmap and the ground keeps moving under it, a working session is the fastest way to find out whether Quethys is the right partner. Two hours on your actual problem — and you keep the write-up either way.
