As user volkk said, unfortunately it would be legally risky for me to disclose the identity of the investor. Which is pretty frustrating, because then you realize that when someone does something bad to you (legally/morally), there are very few (legal) ways to remedy it, especially if they have a lot more money than you.

I can say that he's not based in the Bay Area, so if you are raising money there it is very unlikely you will run into him.

I can also say that our best investors were RightSide Capital, based out of SF. They supported us throughout the whole ordeal with the company and even offered to buy out the other guy. They also said that, out of 600+ investments they had done at the time, they had never seen another investor act the way ours did.

> even offered to buy out the other guy

Why didn't this happen? That seems like an obvious outcome of the situation, unless losing the big client is enough to effectively destroy the company.

From the tone of OP's story, it seems like the other guy probably wouldn't've agreed to the buyout; seems like he had an axe to grind.

But does that matter? The other guy didn't have shares, he was owed money. If the investor provides money, there's enough money to pay the other guy off...

and since people that would rather grind an ax than be made whole are probably rational actors, there is almost certainly more to this story.

i'm going to guess that giving his name out in a public forum combined with the contextual knowledge we now have will make it very obvious who OP is. and then its possible for that asshole investor to further sue him for slander or whatever else
