What's the one thing you hate most about marketing advice aimed at early-stage startups?

It's always frustrating when they don't give examples. Especially if they're not particularly good at explaining it in practical terms. A real life example often "unlocks" it.

I hate mentores/lecturers who are certain that their way is the only way whithout too much explanation. Especially if they have no experience with working in a startup. *Both a founder and a marketer

They're too generic and usually not helpful at all. For example mentors tell you to find your audience, which you already defined, and when you ask questions on how to reach them - coming up with real examples and real advice - they press the play button on the BS generator. Also they're very stubborn about their own ways and don't want to hear about anything else.

People using examples from 15 years ago when the landscape of how to kickstart growth is completely different.

Thinks throwing money at everything is the solution. It's not. Early-stage needs solid first principles thinking to set the stage for the coming years.

Go for MVP fast, it's going to be fine. Well if your startup is about visual experience, that's the worst advice you could get.
