"He actually threatens the company's success if I ever try to "sneak a move" on him when in reality his contributions are near 0 for product development as well as S&M."

1) S&M? Sales and Marketing? At some point in the comments you mentioned that he's the financial guy in your team. I assume because you're writing this on hacker news you're the product guy. So I assume you're comparing his tasks with what you do day in day out.

I started a company with three other founders 6 years ago in Berlin. We had depressing times, but also great times. I left the company a year ago to join one of our VC and after 5 years I was the first to leave.

During those 5 years, I had moments were my co-founders didn't live up to my expectations. And the other way around with me. In retrospect I even think that two of us had a burn-out during the time (which results in exactly the behavior, described in the article you've mentioned) and because we had constantly re-invent our jobs.

And during the time were we re-invent our jobs, we're not that productive - or appear not productive - for some time. Give him that time, you'll need it at some point too.

2) You've started that company with him and you've raised funds. Congratulations, because at least your investors are thinking that you are a strong team - otherwise they wouldn't have invested in the first place.

From your ask and comments it sounds like your relation with your co-founder seams to be already hostile. For the sake of your company, you have to put aside feelings and put the interest of the company in front of everything. Which means your _ego_.

get some consultancy and figure out how to communicate on a professional level.

Someone mentioned to put up goals. I assume you have some, so try to reach them. If you don't need them then there is always the option to get another co-founder - maybe a more senior person - into your company.

Good luck.
