The Builders League United is a holding corporation founded by Blutarch Mann specializing supposedly in construction operations. In reality, from behind a myriad of sub-fronts, it secretly controls half the world's governments, led by an evil female overlord known only as 'The Administrator'. Beneath the convincing exterior of their bases of operations can be found computer racks, satellites, rockets and missile installations.
The other half of the world is just as secretly controlled by their rivals, Reliable Excavation (and) Demolition. Each corporation administers its half of the world with a multi-disciplined army of paper pushers. For any problem lacking an obvious bureaucratic solution, mercenaries are contracted to address the situation through a massive application of force. Conflicts between the two companies began as land disputes between their original founders, though the current reason for their ongoing combat, with both companies now under the thumb of the Administrator, is unknown.
BLU and RED share an intense rivalry, with nearly all encounters between the two quickly escalating into brutal and often fatal violence. Inter-company friendship is also strictly forbidden by mercenary contract. Despite this, the BLU Soldier and the RED Demoman became fast friends after meeting at a projectile weapons expo. However, once this was brought to the attention of the Administrator, she pitted them in deadly competition with a mysterious new weapon promised to the winner, twisting their former friendship into a bloody war.
BLU favours a more industrial style of architecture than RED, and while its dress code is rather liberal in terms of clothing, it is required that employees adopt a blue colour scheme for easy identification.

TF Industries is a mysterious corporation based in Washington "devoted to the highest level of craftsmanship and personal security". Headed by the Administrator, they specialise in the very latest in military technology; selling all manner of deadly, cutting-edge devices to prospective buyers. They also run the popular 'Buildables' line of engineering products
Mann Co., (Slogan: "We sell products and get in fights") is a division of TF Industries. Originally founded by Zepheniah Mann, it was left to his Australian aide and tracker Barnabus Hale in his final will and testament under the name 'Mann & Sons Munitions Concern'. The company is currently run by Barnabus' descendant Saxton Hale, who operates on the policy that if you aren't 100% satisfied with their product line, you can take it up with him. They publish the 'Dapper Rogue' catalogue for the "gentleman scoundrel", of which the Spy is a purveyor. The Administrator is also known to make use of Mann Co. for custom orders via Miss Pauling. They were the subject of a senate investigation in relation to their alleged part in the tragic destruction of American monkeynaut Poopy Joe's capsule during takeoff, which their lawyers firmly deny.
