This starts with a story:

In the summer, one founder of a VC-backed startup approached me to manage his LinkedIn profile, through which he acquires clients (personal brand building).

It was a classic job interview, where the assumption is to create a conversion (you are active on someone's account, building their personal brand, as the account grows, people are noticing you, write to you, you arrange a call, and maybe close a sale)

I asked if there was a possibility of getting equity in this position, because the other positions they had advertised (whether tech, GTM, sales, some small percentage of equity) did offer even a small %...

The answer was "No, this position does not include equity."
