Kwikowski Mutual Interest Group was a presumably Mars-based company, existing during Solomon Epstein's lifetime. It is presumed to have merged with Jules-Pierre Mao's company some time in the 150 years between the invention of the Epstein Drive and the Eros incident, forming Mao-Kwikowski Mercantile.
Caitlin Esquibel, Epstein's wife, worked as a resource manager at the company's research center at Dhanbad Nova.
