Most creators price sponsorships by guessing, then lose a week to DMs. slotsbid runs your slot like a lot at auction: publish it, sponsors bid against each other openly or by sealed offer and the top bid wins. You approve every ad before money moves, and payment settles on the platform. No rate card, no haggling, no chasing invoices. Free to set up, no subscription we take 10% only when a slot sells. Your flat rate was probably too low.
