MarketPay has shut down.

Thank you to every customer, member, and supporter who gave us a shot. You made MarketPay what it was, and we're grateful for it.

What it was

Reddit-style communities for niche categories — watches, sneakers, trading cards, vintage, vinyl, retro gaming — with full peer-to-peer marketplace mechanics on top: listings, auctions, offers, ratings, messaging, and a cashback loyalty system. Built in Michigan.

Community-driven

Niche marketplaces created and moderated by their members. Each community sets its own rules.

Secure payments

Stripe Connect with seller onboarding, three-day buyer-protection window, and durable payouts.

MarketCash loyalty

Closed-loop loyalty credit. Buyers earned 5% back, sellers 10%, with a full ledger and listing-bonus promotions.
