Who voiced Grady in Aperture Desk Job?

Grady in Aperture Desk Job was voiced by comedian Nate Bargatze. Grady is an artificial-intelligence core who recruits the player into increasingly reckless product-testing schemes inside Aperture Science.

The character begins as an apparently helpful workplace assistant, but his enthusiasm quickly becomes dangerous. He persuades the player to test weaponized toilets and later a makeshift turret assembled from weapons parts and a toilet shell. His friendly, rambling delivery is central to the game’s comic tone.

Nate Bargatze’s performance is distinct from the other major voices in the game. J. K. Simmons reprises his Portal 2 role as Cave Johnson, Aperture’s bombastic founder, while Debra Wilson voices the Prison Warden and Announcer. Stephen Merchant, despite being strongly associated with the Portal series, voiced Wheatley in Portal 2 rather than Grady.

Aperture Desk Job was released in 2022 as a free Steam Deck showcase. Its story expands the Portal setting through a short workplace satire, with Grady serving as both the tutorial guide and the player’s unreliable partner in disaster.
