Tesseract

Tesseract Labs is a British technology company that makes products like the Quantum line of computers and nexusOS, along with other products.

History
Tesseract was founded by Evan ****** and Parker ******* (these people exist in real life so the last names are blocked) in London in 1998, it was originally a hobbyist company, but they then moved on to create more mainstream technology.

Name
Tesseract Labs, contrary to popular belief, was not named after the Tesseract in the Marvel Universe. It was named after a 4d shape called a tesseract. Their slogan back then was "Reaching into another dimension", so it's not that big of a surprise why they went with that name.
