From your additional comments, it sounds like the CEO has access to money from his personal wealth, but is not willing to put it to work at his own company. This sounds like he has not enough confidence in his own abilities and the team to make a decent ROI. I consider this a big red flag.
I'd recommend reconnecting with the 10 engineers who already left to see if they can help you line up a new gig. Once you have an option, you can have a conversation with your CEO and try to negotiate a better offer that would convince you to stay. If he fails to do so, he at least had a chance and you will find out quickly how much you are worth to him.
