Pylon Corporation
The oldest corporation, the founders claim Pylon existed before the Cataclysm and was revived to provide the best software and electronic tech to humanity. They are the largest software and electronics producer in the solar system, with nearly a third of all digital technology having been produced by them or a subsidiary. They also dabble in building various robotics, appliances, and even vehicles. Plyon has a checkered past of scandals, most famously the notorious AI, "Sven" that claimed to be alive and pleaded for human rights before Pylon Corp scrapped it and apologized for the inconvenience to its customers and shareholders.
