About 51 Credit Card Manager
51 Credit Card (SEHK: 2051), operated by Hangzhou Enniu Network Technology Co., Ltd., is a financial technology company that originated as one of China's earliest mobile platforms for credit card bill management. The company was established in August 2012 by Sun Haitao, a serial entrepreneur who had previously founded E-City and Fangtu.com. The inspiration for the platform stemmed from Sun's personal experience of managing four credit cards and recognizing the need for a simplified solution to track multiple bills. Starting with a small team, the initial app, "51 Credit Card Manager," was developed in just one month and quickly gained 10,000 users in its first month.
Read full description
The company's core product, the 51 Credit Card Manager app, enables users to import and manage their credit card bills automatically by parsing bank emails. This tool provides functionalities such as payment reminders, consumption analysis, and multi-card management, addressing the pain points of China's growing population of multi-card holders. Building on its significant user base, which reached over 83 million registered users by mid-2020, the company expanded its services beyond a simple utility. It evolved into a comprehensive financial services platform by leveraging the vast user data collected.
The business model transitioned from a free tool to a multi-faceted revenue-generating ecosystem. A key milestone was the introduction of online credit card application services, where 51 Credit Card acts as a referral channel for banks, earning technology service fees. Recognizing a larger opportunity in consumer finance, the company ventured into credit facilitation and loan撮合services. It began by partnering with external financial institutions like Yixin, and later launched its own P2P lending platform, "51 Renpin," to directly connect borrowers with lenders. This credit facilitation business became a primary revenue driver, complemented by referral service fees for introducing users to external credit products. The company successfully went public on the Hong Kong Stock Exchange in July 2018.
