PromoExchange

A full payments marketplace, designed and shipped by one engineer

PromoExchange (promoexchange.io) is a marketplace where social media creators sell promotions to businesses. Creators publish a public channel listing what they offer; buyers book and pay through the site; funds sit in Stripe escrow until the promotion is delivered. It replaces the scattered DMs and email that this kind of deal usually runs on.

Sheldon Soloa, BraneBridge's founder, designed, built, and shipped PromoExchange solo — product, frontend, backend, payments, and infrastructure.
