Fivestars

Fivestars was a customer loyalty, rewards, and payments platform for small and mid-sized brick-and-mortar merchants, founded in 2010 and headquartered in San Francisco. It combined an automated marketing engine, a customer loyalty and rewards program, and integrated card payments so local businesses could turn one-time shoppers into repeat customers. Fivestars was backed by Lightspeed Venture Partners, Menlo Ventures, and Y Combinator, and historically operated a developer program exposing loyalty, promotions, and customer APIs. The company was acquired by SumUp in 2021 and its product has since been folded into SumUp Connect (SumUp Loyalty); the fivestars.com domain now redirects to SumUp's loyalty program and the standalone Fivestars developer portal and public APIs have been retired. This profile is retained in the API Evangelist network as a historical company record.

Fivestars is profiled on the APIs.io network. Tagged areas include Company, Loyalty, Rewards, Payments, and Point of Sale.
