Great Idea but Somewhat Lacking Execution (I will not promote)

I recently got hired as an intern (software-related position) at a local startup and honestly I really like the premise of their E-commerce website. However, I kind of feel bad because I feel like the person in charge of advertising and social media content creation is their executive assistant. I don’t know if that is actually included in their job description but it’s really obvious that the guy does not know what he’s doing. On top of that, I don’t think he has a hint of graphic design knowledge. Their UI is also kind of bad but I don’t feel like it’s my place to say that, especially since I’ve only been here for a week plus it’s not really connected to my role at all. Honestly, I feel like they should have prioritized getting someone to take care of their creatives, especially since they’re nearing launch. With that said, does anybody know what I can do to help? I truly believe in the owners’ vision but I know they’re bound to fail just because I know consumers are really really into visuals. At the same time, I don’t want to offend them either as I’ve barely been here for a week.
