Since you are debating whether to let go 100% of your salary for your startup, you can also think about how much % you are willing to invest in your startup for getting outside help (yes, even for coding). This route is often completely ignored by founders but if you get freelancers/contractors from the right geography, you might end up speeding up your project more than if you spent 100% time on it. Many new founders don't think of this route because they usually have a individual contributor role in their full-time job and don't appreciate the productivity scalability in managing others.
