Translation gradually if you can! See if you can work a day less, maybe via contracting at your current firm, or for different ones. Make sure that you have at least 1 real workday to crank out a MVP (and if you can, add evenings and/or weekends sometimes). As soon as you have real customer/investor interest, you can dial down your contracting as you dial up your business. This is not without risk but it’s way less risky than a Big Bang approach, and this worked well for me personally (founded Transloadit exactly like this which I’ve been doing 5 years fulltime now, with 4 years of gradually ramping up engagement while contracting for my old employer and a few others). I do realize all situations are different and I was rather lucky/privileged to be able to pull it off like this. But given your position & savings you are in a better spot than I was. But maybe also more to lose, so I won’t pretend it will be easier for you!
