About this list
Development on this page ranges from training a model on the client's own data to wiring a hosted API into a product. Square Root Solutions shows the split inside one portfolio: its Druid Learning platform is model engineering, with transformer classifiers and spaCy entity recognition labeling assets across 140-plus languages on Airflow and Kafka, while its EduSmart Planner for CJ Fallon calls Eden AI and ChatGPT. b.telligent fine-tuned BERT on CSS Insurance's manually labeled history to categorize around 60,000 feedbacks a year in four languages, and built KUKA's sales assistant on GPT-4o. Kortical's Deloitte build took a tax computation from five hours to six minutes at above 90% accuracy, and its NHS Blood and Transplant forecasting across 40 blood products is reported at a 54% reduction in expiries. elunic's inspection cells at voestalpine retrain continuously on live line images. Flowtale's Ekstra Bladet write-up benchmarks gradient boosting, random forest and support vector machines and publishes the accuracies, a 48% on one class among them. Storm Technology's documented client work is Dynamics 365 and Power Platform delivery with AI as an advisory offer, and Vention's client studies show little model-building.
A mid-market buyer should price the build by which kind it is, because the skills, the timeline and the running cost differ. Ask which named engagement resembles yours, whether the model was trained or called, where it runs, and what evaluation set was left behind so your own team can tell when it degrades.

Expert Insight
Why mid-market fit matters for AI Development
Mid-market budgets buy a system that fits the ERP, CRM or telematics platform already running the business, and the agencies here document work built into those systems rather than beside them.
There is rarely an in-house machine-learning team to hand over to, so documented training, managed operation or a product the client's own staff run is the evidence that matters most at this size.
The first engagement funds the second: a bounded scope with a measured result is how mid-market AI budgets grow, and the case studies here carry the numbers.
Frequently asked questions
