The move to SF: what founders wish they'd known
Bring enough cash for deposits, a temporary stay, transit, food, and a few surprises. Do not use a company deadline to accept an unverified room. A short legitimate sublet can give you time to learn neighborhoods and find a durable home.
Expect the city to be physically tiring at first: hills, weather, transit, errands, and new social rhythms all take time. Keep the first month simple and protect sleep.
The useful move is not the fastest arrival. It is the one that leaves you able to build after the boxes are gone.
