I don't think we have enough information (or even the professional capacity) to advise you wisely for the best expected return. So many unknowns here; for instance,

> what d'you mean by ex-founder and by what corporate action or process did you come to attribute this title to yourself?

> Why have you held your shares till this time?

> Why are you skeptical of the future of the company? D'you have a personal beef with the hardball CEO or is the company really doomed in your opinion?

> Who approached who (I mean you or your hardball CEO) to leave the company? To be clear, did he notify you of their intention to raise money and ask that you sell off or did you hear that they're about to raise money and then decide that you want out?
