Using duplicates of himself in order to constantly learn new knowledge and abilities, Jamie Madrox formed a detective agency in District X with long-time friends Guido and Rahne. The agency was originally named XXX Investigators and their first case was investigating the murder of one of Jamie's duplicates. After the long and involved case, it was actually Guido who recommended changing the name of the agency to "X-Factor Investigations" as an homage to the superhero team to which they all once belonged. However, this new incarnation of X-Factor has no relation with the U.S. government, as the previous teams.
Jamie Madrox expanded the agency in the wake of House of M--adding Siryn and M--and began to investigate the mutant Decimation. Rictor, suffering from feelings of doubt and depression from no longer being a mutant, was pushed off the roof of a building by one of Jamie's dupes. After M saved Rictor from the fall, Jamie was able to convince him to join the agency as well.
Wolfsbane left the team following the battle over the mutant baby and joined X-Force, though X-Factor Investigations doesn't yet know where she is.
