- "The Yeerks have been busy. They control a computer company called Matcom."
- ―Erek King
The Matcom Corporation, simply known as just Matcom, is a computer company owned by the Yeerks. Specializing in software designs for military applications, the Yeerks attempted to use Matcom to harness the power of the Pemalite crystal in an attempt to access and control every computer on Earth.
- "A project I can't talk about for this company called Matcom. [...] There are some very exciting things going on with this Matcom. The thing they want me on isn't military in any way. But... well, they do carry on some very secret work. I guess some of what they do is probably military."
