I'd love to chat if you have a few minutes, email is in profile. I'm really asking though because I see a ton of opportunity in the form of abandoned side projects on HN. Connecting sales with product seems to be the differentiator with smaller side hustles, just as it is with many larger breakout products. Filling a niche and finding PMP is always the most important goal, but it doesn't help to have a little kickstart with a funnel full of users, especially when still working towards PMP.
I have no qualms about paying somebody to help market but only if there was a way to actually track what their sales were. I wouldn't want to give equity or revenue based on them just marketing but would give a commission on each sale they generated.
Ex: I have a self-published book https://hapibook.jjude.com. The book is complete. I'm creating videos. In this case, I don't mind sharing revenue.
Planning to present on HN though when beta state will be reached :-)
I would go for revenue split which is simpler to track and set up.
However, revenue sharing is going to makes sense for everyone, more of the time. Equity is only going to pay out during a liquidity event, and effect on revenue can be measured in a fair and ongoing manner.
