Rhona Caldwell
Founder and lead data scientist
Rhona spent five years in financial-services ML before starting the company. She leads model design and handles the technical side of client proposals.
How we got here
Ai Integrity Alliance began when our founder, Rhona Caldwell, left a data-science role at a large Edinburgh financial firm. She had spent five years building machine-learning models that saved her employer millions, but she kept meeting owners of smaller businesses who assumed AI was out of reach for them. A logistics company in Dundee. A craft brewery in Inverness. A chain of dental practices across the central belt. All of them were drowning in manual data work that a well-scoped model could handle in seconds.
Rhona recruited two engineers she trusted and set up shop in Long Trompthorpe. The first project was an invoice-reading system for a wholesale florist. It took eight weeks to build and paid for itself in under four months. Word spread quickly.
By mid-2023 the team had grown to nine. We moved into a converted mill building at 566 Sporer Mount, which gives us enough space for a small server room, a meeting area, and the whiteboards we go through at an alarming rate.
Mission and values
Our mission is to make responsible AI accessible to businesses that do not have dedicated data teams. "Responsible" is the key word. Every model we deploy comes with documentation that explains, in plain English, what the model does, what data it uses, and where its predictions are likely to be wrong. We think that kind of transparency should be standard, not a premium add-on.
Transparency first
We publish model cards for every system we deliver. These cards describe the training data, known biases, accuracy metrics on held-out test sets, and recommended human-review thresholds. If a model is not confident enough to act alone, it flags the decision for a person.
Fixed pricing
Scope creep is the enemy of trust. After the initial audit we quote a fixed price for the agreed deliverables. If the scope changes, we re-quote before doing additional work. No surprise invoices.
Data stays in the UK
All training and inference happen on servers physically located in the United Kingdom. We do not send client data to overseas cloud regions, and we contractually commit to that in every engagement letter.
Measurable outcomes
Before we write a line of code, we agree on the metric that defines success: hours saved per week, error rate reduction, cost per processed document. If the metric does not move, we have not done our job.
The people behind the work
We are a team of nine, split between engineering, project management, and client advisory. Here are the people you are most likely to speak with.
Callum Bryce
Engineering lead
Callum manages the build phase of every project. He came from a DevOps background at a health-tech startup and is obsessive about deployment reliability.
Amina Osei
Project coordinator
Amina is the person who keeps timelines honest. She runs the shared Kanban boards, schedules demos, and makes sure clients always know what is happening next.
Key milestones
A short history of the things that shaped us.
March 2021
Company registered in Scotland. First project signed: an invoice-extraction system for a wholesale florist in Perth.
November 2021
Completed our fifth project. All five clients renewed for ongoing support, giving us the recurring revenue to hire our fourth engineer.
June 2022
Launched our demand-forecasting product after piloting it with a Glasgow food distributor. Their 22% waste reduction became our most-cited case study.
January 2023
Moved into the converted mill at 566 Sporer Mount. Installed an on-premises GPU cluster for training sensitive models without cloud dependency.
September 2023
Team reached nine people. Introduced formal model-card documentation for every deployment, making bias and accuracy reporting a default part of delivery.
April 2024
Passed 30 completed projects. Median client payback period confirmed at seven months across the full portfolio.
2025
Working on three concurrent builds, including our largest engagement to date: a multi-site document workflow for a Scottish NHS trust procurement team.
