Hannah Weiss-Martin met RDP biologist Javier Florentin in a cave diving expedition in Cordillera de los Altos,where they discussed founding a company together to explore quantum coherence in the brain. Weiss-Martin's groundbreaking viral interference experiments at Caltech in 108 BFC had demonstrated sustained quantum coherence in biological nano-structures, and Florentin's experiments on hibernating animal consciousness had demonstrated there was analogous states in larger animal brains. Nexus was incorporated in 77 BFC in the Argentinian Mancomunidad which had no laws on human experimentation, and they rented the abandoned Acrux-2 oil rig (offshore structures which were used to extract petroleum for the fossil-economy) in Argentina's Colorado Basin as their main working space

    With their Series A funding the company worked on connecting retroviral delivered Posner molecules in the brain to an entangled processor, which needed to be quantum-native to preserve the phase relationships tracking memory flow and temporal associations. This was successful in detecting previously uncaptured temporal thought patterns and associative memory formation, and their first contract was with Havfélög to develop screening techniques for selecting marines.

    During this time Javier Florentin was in a relationship with celebrity aestheticist Julieta Gómez Romero, but she was killed in 70 BFC during one of the Mancomunidad's many periodo violento. It was not clear if Havfélög were involved, but that year Nexus cancelled all contracts with them and sold the rights to their neural models to Pharmatica, and the remainder of their assets to Microsynth the following year. Perhaps the most promising development from their technology was the creation of ghosts, however this was mothballed by Pharmatica during the acquisition and never developed further.

    Nexus operated as a division of Microsynth for 10 years before being divested as a wholly owned subsidiary, MNex, to avoid new biotech market disclosure rules. Due to external power and compute requirements BN was never cost compatible with the more commercially successful MemAmp technology, which in the 50s began to be powerful enough to replace BN in military applications as well. In 55 BFC MNex restructured, removing all divisions except those working on commercialising some of Javier's hibernation and cryopreservation research, and the company was successfully refocused around these. The main MNex laboratories are located in Silicon Valley in the United States, however the companies legal headquarters remain at Acrux, and some research which would otherwise be illegal is still conducted there.
