Iron Helpers Inc was a company that designed mechas.  These mechas were very popular and were used in mining, space exploration, construction, military, and home use.  Many of their mechas were hacked and used to kill many people (The Dude survived an attack on Shanghai).  Many lawsuits were filled against them and during the Hacker Hunts, its headquarters and most its branches were destroyed.  It appears that all the engineers were killed during the attacks.

Sandra Hoffman was an employee of the company before she retired.
