UK AI studio · Regulated operations
Governance before automation, every time.
North Stack is a UK AI studio built for messy data, closed systems and regulated stakes. We map how work really happens, build human-in-the-loop systems and run supervised agents for businesses where getting it wrong matters.
Who we are
Their problem isn't the technology. It's trust.
Buying an AI licence is easy. Being able to say who is accountable for what it decides, which rules apply, and what you would show a regulator who asked, is the part nobody has solved. So that is where we start.
Before a single workflow is automated, we help you understand the regulatory layer you are already inside: which rules apply, where the data that evidences them comes from, and who owns the answer when someone asks.
How we're built
Small, senior, and built to surge.
Senior people on the actual work
No pyramid and no juniors learning on your account. The people who scope your operation build and run it.
Generalists and specialists at one table
Operations strategy, applied AI engineering, regulated-sector knowledge and clinical human-in-the-loop instinct in the same room.
A studio that surges
A five-person core, partnered with an award-winning technical studio, scales up for a build and back down. You pay for the work, not the bench.
We say no in writing
Our audit tells you which workflows not to automate. Telling you not to build is a successful engagement.
The bench
Every side of a regulated operation, on the team.

The method
The North Stack Ladder.
Five rungs for adopting AI in a regulated operation. Each adds exactly one new thing to trust, and earns it before the next is built. Build only what pays back; never automate past the point a person can still be accountable.
- 01
Rung 1
Mapped: you can see the work
Before anything is built, the whole operation is visible and every workflow is scored. Humans decide; nothing is touched.
- 02
Rung 2
Assisted: AI reads, humans act
AI retrieves, summarises and drafts. Your people still make every call.
- 03
Rung 3
Automated: pipelines type, humans approve
Pipelines read the inbound flood and compile the periodic returns. People approve before anything commits.
- 04
Rung 4
Integrated: systems agree
Your sources stop contradicting each other, and approved results write back into your core system.
- 05
Rung 5
Orchestrated: agents work, humans hold the gate
Supervised agents operate the closed portals you cannot integrate with, with a person approving every critical action.

Start with the audit, not the build.
A fixed-fee operations review: we map the workflows draining time and control, score each one, and hand you a costed plan that includes the work we would tell you not to automate.
