Well, if I’m reading this in Germany, chances are, this isn’t IPA (if it was, I’d expect this to read like English “decent”?), so the other pronounciation option is English “designed”. But if you’re somewhat negative, it could also be pronounced like English “dissent”, i.e. with a negative connotation. I can’t really speculate on which of these words would spring to mind first though.
IMHO you should probably use more clearly defined words to be associated with your company. OTOH if it gets (some, a minority of) people thinking, it probably did its job as well.
