A quick search shows MathCraft Security Technologies [1] and MathCraft(TM): Math In Action [2] by Cycorp both exist.

On a similar note, I find it amusing that accidentally going to minecraft.com instead of minecraft.net brings you to the home page of a literal mining engineering consultancy [3].

"MineCraft Consulting provides innovative solutions and project management services for coal mining projects in Australia and Overseas."

"MineCraft is a registered trademark of MineCraft Consulting Pty Ltd."
