WHY TEAMS CHOOSE US OVER A TYPICAL DEV SHOP
Most AI projects run. Ours changes something.
The gap in most AI work isn’t the models, but the engineering and ownership around them. A pilot that never touches your systems, data, or workflow was never going to change a number.
Book a discovery callThe typical arrangement
An account manager sits between you and the people doing the work. The vendor owns the roadmap. You find out what's on it at the demo. Senior names in the pitch, junior hands on the keyboard. The engagement ends when the invoice does.
How Halcrow works
I scope, lead, and answer for each engagement personally. Your roadmap stays yours. I run it with you, in your language. The team I bring is the team that builds. Everything gets handed over properly so you can own and extended what gets built.
WHAT I CAN LEAD & DELIVER WITH MY TEAM OR YOURS
AI development services
Applied AI & agentic systems
LLM-powered workflows, agents and copilots built into the tools your people already use, designed around a measurable job.
Automation & intelligent operations
Document handling, triage, scheduling, and reporting. Hours back every week, engineered reliably enough to trust.
Data & cloud foundations
Pipelines, integration, and infrastructure that make AI and machine learning models accurate, secure and affordable at production scale.
AI in your product
Features your customers pay for (search, recommendations, assistants) shipped inside your existing product.
Model evaluation & guardrails
Evals, monitoring and safety rails so the system stays accurate as your data, providers, and models change.
Pilot rescue
You’ve run a proof of concept, or maybe several - custom-built or off-the-shelf. We assess what’s worth keeping and engineer the survivor into production.

WHY NOW, NOT NEXT QUARTER
Without a technical leader accountable to you, you're risking project drift
Technology initiatives don’t fail suddenly. They drift. The same problems go unaddressed every quarter. By the time anyone notices, months of budget have gone with nothing to show for it.
It's a slow, quiet deterioration that looks like business as usual until it isn't.
HOW TO START WORKING WITH ME
Three steps to work with me. The first one costs you nothing but gives you what you need at this moment.
STEP 1
Book a 30-minute discovery call with me
You describe what you’re trying to build or fix. I ask the questions a CTO would.
STEP 2
I send a scope you can hold us to
With clear phases, honest estimates, named risks. Written so your leadership team can read it.
STEP 3
The team embeds and we start with you
My engineers build; I lead.
FAQ
What I'm asked on most scoping calls
How do you price?
Day rates for embedded engineers and my fractional CTO time, or a scoped phase price where the work suits it.
Who owns the code and IP?
You do. Everything we build for you belongs to your business.
Can you take over an existing build or vendor situation?
Yes, a meaningful share of our engagements start as rescues or take-overs.
How quickly can you start?
Scoping within days. Engineering start is typically weeks and not months.
Where are you based?
Sydney, working with clients across Australia.
