He’s some famous has-been (exited in the 90s, blew all his cash and didn’t make enough) in a hot hype field and zero’ed in on us. We were introduced at a conference, and met him several times since we’re in the same city. We gave him some consulting work to do as a trial, and he was terrible (didn’t turn up, missed meetings etc)
Now he’s claiming that we should give him 20% stake in our company and refuses to leave us alone. Keeps alternating between threatening to sue and reconciliating.
Does he have a case at all? We never agreed to this ridiculousness, and he has no documents in writing. He also won’t leave us alone and started spamming us on person facebook, messenger etc
