The origins of the Beyond Corporation are unclear. They were either created or entirely co-opted by a rogue Beyonder (similar to the entity responsible for Battleworld or the entities involved in the Incursion crisis). A conception entity with reality-altering powers, the Beyond Corporation "debaser unit" played its games with the Nextwave squad and the Mighty Avengers.
Apparently free of its patron, the Beyond Corporation continued to exist as a traditional unscrupulous corporation. They created a Super Hero Division, seemingly for altruistic reasons and corporate PR. However, they also secretly funded super-villains, and would play both sides against each other to protect assets, eliminate competition, or control the media cycle with orchestrated super-battles to protect their clients from the scrutiny of the public's limited attention span.
