The popular self-applied title “founder” is sometimes (often, actually, in places like LinkedIn) just an aspirational buzzword, with nothing actually having been founded, and that can often be discovered without much effort.
If you must “stand out” (another overused LinkedInese expression I think should be retired), can’t you find a way to do it by demonstrating real achievement or skills? No? Want to fake it ’til you make it? Well, then found away until you find a way.
