Jasper ai CEO and co-founder, Dave Rogenmoser, in a YouTube video, explained why the name change was due to a trademark legal suite from Disney (Marvel) for the name Jarvis. J.A.R.V.I.S  is the name of Tony Stark’s AI personal assistant in the movie Iron Man created by Marvel Studio. Marvel studio taught there is the need to protect their trademark name for Jarvis, so they got their lawyers involved and sent the cease-and-desist notice. Instead of fighting the lawsuit in court, the AI copywriting team chose to rebrand to Jasper. Considering they’re up against a giant like Disney, I think it is the wisest thing to do in order not to get distracted and drain all their bank account fighting for a name.
