GameSim

GameSim provides full game development services to publishers or works as a co-developer for other studios. In practice that means building software for you when nothing off the shelf fits.

It makes the most sense for companies with a specific process to automate. Alongside the main category they mention Media and Entertainment and Video Games. They are a small team, 11 to 50 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

GameSim is based in Orlando, Florida. More on gamesim.com.

Things worth asking about: portfolio relevance, who owns the code, and how they handle changes. A short pilot with your real data tells you more than any demo.
