Zimp, a startup founded in 2013, has developed a loyalty program that offers transparent and easy-to-use rewards. Each Zimp point is equivalent to $1.00 to spend at partner stores, and there are no hidden limitations or bureaucratic mechanics. Users have full control over when to spend their points, and the points never expire. For shopkeepers, there are no sunk costs or fees involved, and they only pay when they make a sale. Zimp aims to increase customer loyalty and generate incremental consumption without pocketing the money dedicated by the shopkeeper to gratify their clients.
