Not much is known about HEXAeco. Supposedly, it produces clean and ecofriendly power from automated energy plants, which it distributes as red energy through pipes to its various consumers. Grand Metropolis is a futuristic city apparently dominated by HEXAeco.
The company's logo is a stylized green hexagon, thus hitting both the "hexa" and the "eco" of its nomenclature.
In Sonic Heroes, HEXAeco's Power Plant and its local consumer, Grand Metropolis, were taken over by Neo Metal Sonic while he had control of the Eggman Empire, who made his forces siphon HEXAeco's energy and shut down the iridescent sky-roads. When Team Sonic followed Neo Metal Sonic to this city, the trio liberated HEXAeco from the rogue robot's control.

- HEXAeco appear to be an allusion to Texaco, a real-world oil conglomerate. The logo also uses a modified version of the bold "Vipnagorgialla" font.
