CoolSim

CoolSim is an advanced CFD-based tool available for optimizing energy consumption in data centers. 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 Data Center. 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.

CoolSim is based in Concord, New Hampshire and around since 2008. Their site is coolsimsoftware.com.

Things worth asking about: portfolio relevance, who owns the code, and how they handle changes. Ask for a trial on your own data, not a canned demo.
