You're in the group chat at 10pm talking someone off a ledge because their launch post flopped. You rewrite captions for friends without thinking. You've got 12 years of taste and no patience for another 6-month retainer contract.
SOS is basically that, but the person on the other end actually pays you. Someone posts a question, you answer if you've got something useful to say, and you keep 75% of what they paid. If you're slammed, ignore it. Nobody chases you. There's no onboarding call, no Slack to live in, no "quick sync."
