The Prosperity Group ascended into the corp ranks before the Fall, meeting the high demand many new stations had for microgravity agritech, aquaculture, hydroponics, and other sources of food.
Expanding into pharmaceuticals as well, Prosperity is considered the lead supplier for the poor man’s food. Their cultured faux-meats and protein-enriched nutrition additives are in high demand. This corp earned some sympathy when it lost an entire habitat to some sort of drones outbreak a few years after the Fall, though some have suggested this was just a cover story to hide an unfortunate accident resulting from experimental drug testing on an unwitting populace.
