Taking inspiration from Sofia Lamb's appeal to the lower class, Fontaine created Fontaine's Home for the Poor, which provided for the destitute in Rapture's free market society. Fontaine created the Little Sister's Orphanage, a charity which was a front to get parents to willingly give up their children, who would then be turned into Little Sisters to generate ADAM.
Tenenbaum informed Fontaine that they required little girls to mass produce ADAM. Fontaine set up an ADAM business, Fontaine Futuristics, employing Tenenbaum and Yi Suchong to research and develop Plasmids and Gene Tonics. Tenenbaum went to Fontaine with a proposal that he fund research on the slugs, and he quickly saw the business possibilities of the endeavor. That sea slug produced raw ADAM, a substance with near miraculous medicinal properties. In a chance encounter on Fontaine's fishing dock in Port Neptune, Brigid Tenenbaum observed the result of a sea slug's venom upon an injured hand of a worker. He regularly disguised himself with various false identities to carry out crimes.

Fontaine loved nothing more than the power of a good grift. He soon expanded his income by creating a smuggling ring to bring high demand, contraband items into Rapture. Fontaine arrived in Rapture sometime in 1948 where he soon expanded his income by creating a smuggling ring to bring high demand, contraband items into Rapture.
