Are there any other projects that work on the same or similar problem? Maybe you could join one of those. If you're bound by an NDA and a noncompete, check if you can get rid of either or if you really want/have to stay where you are see if you can:

- get the liberty of hiring people for your own team

- get flexible work hours allowing you to show up when you want to and pick the problems you'd like to solve

Also, unless you haven't done so already, get/see a financial advisor to make sure you don't blow through 10M in a few years. Do something like building an apartment building (low income or not), invest in providing a basic service that'll always be around and will make you money for decades to come, etc.
