HEROES FOR HIRE traces its roots back to the one-man "Hero for Hire" business founded by Luke Cage,

which offered superhuman security and investigation services for a fee.
Cage later went into business with the martial artist Iron Fist as Heroes for Hire,

a profitable partnership that lasted for years until circumstances forced the duo to break up,
though they remained good friends.

Nowadays, Heroes for Hire is a group of (mostly) superpowered mercenaries who hire out their aid in exchange for money.
