- “Greetings! It is I, your insanely great leader, Steve Mobbs.”
- ―Steve Mobbs makes an announcement to the Mapple universe[src]
Steve Mobbs was the eccentric and reclusive founder and CEO (Chief Executive Officer) of Mapple.
Steve Mobbs is a bit of a recluse, spending most of his time at Mapple's undersea headquarters. He is also an eccentric: He always wears a black turtleneck, and one of his favorite phrases is "insanely great." Mobbs also has a strong vain streak, as seen when a Mapple employee told him that Lisa was there to see him, and he was busy checking on how many times he appeared in search engine results. Mobbs' vanity is also seen when he applies the phrase "insanely great" to himself. One of the store owners implied that he had once been fired from his own company yet they ended up bringing him back later on.
Mobbs makes occasional company-wide announcements which are fed to all Mapple Store locations. Bart Simpson pranked one of Mobbs' announcements, making it sound like Mobbs was calling his customers losers, saying he had nothing but contempt for them, and donating all of the company's profits to Microsoft, as well as making it seem as though Steve Mobbs was homosexual and that Bill Gates was his boyfriend.
When Lisa visited Mobbs to ask for a reduced payment plan on her $1,200 MyBill, Mobbs had her work off the bill by standing on a street corner wearing a MyPod costume, handing flyers to people and telling them, "Think differently."
Mobbs reappears in A Tree Grows in Springfield, where it is revealed that he is now deceased.
