So lets look at de risking the company offering.

If the company is derisked from the product side (even tough there is ton of work left) than you are like any other employee . If, on the other hand, you have some sort of a proprietary knowledge that is still needed for de risking to occur, than you have leverage.

When I read between the lines, I see that the CTO already derisked the product in the two years prior, and its looks like the CEO is derisking from the market side (i.e. have traction).
