GRUMBL is a large tech conglomerate.
GRUMBL was already a large and trusted tech company led by Austin Van Der Sleet when Hexus the Living Corporation acquired it as part of their plans conquer Earth. When A.I.M. was in dire financial straits, GRUMBL stepped in to buy a controlling stake and use M.O.D.O.K. and Monica Rappaccini's inventions to perfect the GRUMBL GRome and enslave humanity.
During a GRUMBL leadership conference, M.O.D.O.K. opened a portal to Broodworld so he could subdue the Brood and gain the approval of the GRUMBL social circle. However, a group of Ciegrimites came through instead, causing them to party excessively and kill many GRUMBL members in the process. Eventually, M.O.D.O.K. was able to kill the Ciegrimites and save the remaining GRUMBL members by exploiting the Ciegrimites' insecurities.
As the GRome's launch approached, M.O.D.O.K. was able to fix remaining bugs of the GRome and make it ready for launch. However, M.O.D.O.K. was able to sabotage this launch by making the GRome drive nearby animals into a frenzy. Meanwhile, Austin turned against GRUMBL to save Sherlock until he was ran over by Gary, causing the GRUMBL Board of Directors to hire Janice as the new public face of GRUMBL.
