A year ago I started a tech company with a co-founder. We are still stealth, building out some of the core technology. Things have been going smoothly, and we will soon be fundraising.
I discovered through mutual acquaintances that my co-founder has an illustrious history of sexual harassment at his previous places of employment. They are stories not unlike those of the Uber story. Allegedly, my co-founder was never punished, remained rather successful and maintained promotions, but the other parties involved quit or were moved to other departments/teams/etc.
The stories were plausible, not because I suspected this of my co-founder, but because the acquaintances were pretty detailed about events that went down.
I have absolutely no idea what to do in this situation. These events were a few years ago, and I wasn't a part of them. To me, it's also hearsay... but like I said it's plausible. We are far in building out our business, but I'm afraid if I don't address this, it may come back to bite me.
Advice?
