Living on a founder's stipend in San Francisco
Divide the available cash by the months it must last, then reserve housing, food, transit, insurance, taxes, and an emergency buffer. Base the rent decision on the conservative number, not a future funding event.
Use a simple weekly ledger. Separate company expenses from personal living costs and do not let a roommate arrangement obscure either. Choose furnishings and subscriptions that can leave with you or be sold easily.
The aim is not heroic deprivation. It is enough stability to keep making good decisions.
