CardSpring was a San Francisco-based startup focused on payments infrastructure and e-commerce. Founded by former Netscape engineers, the company created a cloud-based platform that connected web and mobile applications to payment cards, allowing developers to build card-linked applications. These applications could manage offers, coupons, loyalty points, and analytics triggered by payment events like swipes or in-store checkouts. The core offerings included a card-linked payment platform that enabled seamless integration with various payment networks, a commerce analytics system called CardSpring Connect, and a Web Service API for secure, real-time interactions. The platform emphasized security and scalability, partnering with First Data to enhance its reach across the U.S. payment landscape. In July 2014, Twitter acquired CardSpring to enhance in-tweet commerce and card-linked offers, while maintaining its openness to developers and partners. The acquisition aimed to expand innovative commerce experiences through Twitter's distribution channels.
