That idea quickly turned into action, and the first prototype was built over a weekend with the other co-founders. Today, ShopBack serves over 50 million users across 13 markets, partners with 20,000+ merchants, and powers over half a million transactions daily. We're building The World's Most Rewarding Way to Shop — and looking for bold, driven individuals to join us.
