Ciara Donnelly
Founder and lead data scientist. Eight years in data engineering and ML. Formerly at Kainos and a Belfast logistics firm. Leads model design and client strategy.
In early 2019, our founder Ciara Donnelly was working as a data engineer at a Belfast logistics company. She kept seeing the same pattern: teams collected mountains of data, stored it carefully, then never used it for anything beyond monthly spreadsheets. The gap between what the data could reveal and what anyone actually did with it frustrated her enough to quit and start Ai Excel Tech.
The first project was a demand-forecasting model for a food distributor in Lisburn. It took eight weeks and reduced their weekly over-ordering by 14%. That single result brought two referrals, and by the end of 2019 we had three clients and a second engineer.
Today the company has grown to nine people. We still operate from Church Lane in South Friesen Green, though half the team works remotely across Northern Ireland and the rest of the UK. Our client list includes manufacturers, retailers, logistics firms and a handful of professional-services companies.
Four principles that shape every decision, from which projects we take on to how we write code.
If your problem is better solved with a simple SQL query or a rules engine, we will tell you. We have turned down projects where AI would have added cost without adding value. That saves everyone time.
A model that sits in a notebook is a hobby project. We deploy to production, wire up monitoring, and stay accountable for accuracy after launch. If predictions drift, we fix them before you notice.
Our reports use words your operations manager can read. We explain precision, recall and F1 scores when asked, but the default output is "here is what the model does, here is how often it is right, here is what to do when it is wrong."
We process client data on UK-hosted infrastructure. Personal identifiers are stripped or pseudonymised at the earliest possible stage. Every project has a data-handling agreement signed before we receive a single file.
Nine people, four disciplines: data engineering, machine learning, software development and client delivery.
Founder and lead data scientist. Eight years in data engineering and ML. Formerly at Kainos and a Belfast logistics firm. Leads model design and client strategy.
Senior ML engineer. Specialises in computer vision and edge deployment. Built quality-inspection systems for two manufacturing clients. Joined in 2020.
Data engineer. Designs the pipelines that move raw data into training-ready formats. Background in cloud infrastructure at AWS. Handles our GCP and Azure deployments too.
Project delivery lead. Manages timelines, budgets and client communication. Keeps engineers focused and clients informed. Ten years in IT project management before joining us in 2021.
Five more engineers and analysts work behind the scenes. We keep the team small on purpose: everyone knows every project, and you will never be handed off to someone who has not read the brief.
A short history of where we have been.
Ciara registers Ai Excel Tech as a limited company in Northern Ireland. First office: a shared desk in a co-working space in Belfast.
Deliver the Lisburn food-distributor forecasting model. Over-ordering drops 14% in the first quarter of use.
Rory joins as the second engineer. We move into a small office on Church Lane in South Friesen Green.
Team grows to five. We sign our first retainer client, a retail chain with 40 stores needing weekly demand predictions.
Launch our NLP practice after building a contract-review pipeline for a Belfast law firm. The system reads 200-page contracts in under four minutes.
Team reaches nine people. Cumulative projects delivered: 38. Longest-running client relationship: five years and counting.
