Validate hardware demand with waitlists before stocking a single unit
Solo founders scaling manufacturing get crushed by inventory management chaos and massive overstock losses from unvalidated demand.
ProtoWait lets solo makers build product waitlists in minutes, track real buyer interest via pre-commitments, and get demand scores to decide production runs. It integrates pre-order payments to confirm demand and auto-alerts when to order inventory safely. Avoid overstock by scaling only on validated signals.
