The best way is to make sure you ACCOMPLISH something. I did the same as you and actually got a massively better role after my startup failed. The reason was because I accomplished something that's hard to accomplish.

How about you get a client before leaving? You should be able to find someone to pay for what you're making. If you can't work an additional 10,15,20 hrs per week at a cushy FAANG job and get a client you probably shouldn't leave to work the brutal life of rejection building a new company entails.
