## About this market
For a software company of 200 to 1,000 people the documented work here is mostly engineering inside someone else's product, with AI as a feature of it rather than the engagement. Vention's studies describe multi-year teams: three engineers over three years on Comet's ML experiment-tracking platform, four engineers over 1.5 years scaling Verfacto's customer-journey analytics, 18 engineers on Infogrid's building-management platform. Spanish Point Technologies moved Kefron's AP invoice-automation product off 70-plus servers to a cloud-native Azure architecture with Azure AI Search, with weekly releases replacing quarterly cycles and NPS up 25%. Square Root Solutions built the content-intelligence engine Druid Learning's product depends on, at 500k-plus assets processed with the stack published. STX Next built appliedAI a Use Case Management Tool that inventories AI use cases against EU AI Act obligations. Alpdev took SYYNCH from zero to the App Store in under six months. Contiamo co-developed Medialine AG's CompanyAI Agent Framework. Wolfgang Digital is on this page by tag: its published work is consumer retail, and the curator says a B2B or SaaS buyer should ask for equivalent numbers.

The sorting question is whether the agency has worked inside a release train it did not control. Ask who owned the repository, how the team was allocated and reviewed, and what happened to the engineers when the engagement ended; for the AI features, ask whether they shipped to the client's customers or stayed internal, since several of the studies here are the latter.
