ZBrush

ZBrush is used by respected film studios, game developers, designers, advertisers, illustrators, and scientists around the world. Put simply, it is about making developers faster with better editors, debuggers and workflows.

The natural audience is software teams. Related areas on their profile: Developer Tools. They are a very small team, 1 to 10 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.

ZBrush is based in Los Angeles, California. Their site is pixologic.com.

Things worth asking about: language support, team features, and privacy of your code. Ask for a trial on your own data, not a canned demo.
