About this list
In the work documented here, generative AI for mid-market companies is assistants over a company's own documents and text generation inside existing systems; the main variable is whose model runs where. Nebuli deploys its own Nano Workspace and AIQ models on private cloud, as at the UK Sports Institute: documents preprocessed into a private vector database behind a smart-search API. Contiamo runs on GPT-4o: a customer chatbot on Stadtwerke Bonn's website for over a year, employee chatbots across housing group Gewobag, and the Product Text Wizard generating multilingual product descriptions for BRAX from its ERP and PIM, with no case-study page stating architecture or evaluation. Kortical's Shopify support chatbot for The Edit LDN reportedly handles 80% of queries unaided. Square Root's EduSmart Planner generates lesson plans from curriculum PDFs through Eden AI and ChatGPT at 250-plus schools. Flowtale's Flowform extracts booking requests into LEMAN's transport management system, cutting handling from up to 15 minutes to just over six, the extraction model unnamed. Wolfgang Digital used custom GPTs to theme Petstop's Trustpilot reviews into ad messaging, and Storm Technology's generative offer is Copilot advisory without a published client delivery.
The sorting question is where your data goes and who holds the model. Ask whether the assistant runs on a public API, a private deployment or the agency's own stack, the error rate on your document types, and who supports it afterward: Nebuli's registered headcount is 2-9, and Contiamo calls the BRAX tool continuously developed, so ask whether that means a retainer.

Expert Insight
Why mid-market fit matters for Generative AI
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
7 agencies in our directory combine verified mid-market client evidence with documented Generative AI work. The current top-ranked are Square Root Solutions, Storm Technology, Wolfgang Digital — ordered by depth of documented client evidence, then our editorial scoring (portfolio quality, credibility, completeness); placement is never paid.
Published rates across this page's agencies run €20–130 per hour (median ~€30). Project totals depend on scope — the rate index at /rates breaks the computed bands down by region, country and team size.
Each listed agency has at least two documented, named mid-market clients — published case studies or engagement descriptions our research actually read, with source URLs stored per client. Logo walls without published evidence carry no weight, which is what separates this list from self-declared directories.
