Industry customer cases

To provide a better service experience

Latin American fitness brands have seen a surge in renewal rates through digitalization.

The customer renewal rate has increased.

An international fitness chain brand has been operating in the Latin American market for more than 15 years, with businesses spanning 8 countries including Brazil, Mexico, and Argentina, and owning more than 500 smart gyms. To address the growing operational complexity and enhance member stickiness, the brand launched the "Omni - channel Interaction Plan", deeply integrating the WhatsApp Business API into its member service system. This not only achieves an annual reduction of $1.8 million in operational costs, but also reshapes the customer relationship management model of the fitness industry.

The monthly traffic of the cross-border e-commerce platform has increased by 20%...

Monthly traffic growth

The online customer service system, like a digital bridge, establishes a real-time communication channel between brands and consumers, serving as the core hub for modern enterprises to maintain customer relationships. After a cross-border e-commerce platform accessed the Gangqin Cloud intelligent customer service interface, it significantly optimized the service response chain. Relying on its lightweight API integration capabilities and scenario-based industry solutions, Gangqin Cloud helps enterprises quickly build a highly elastic customer service system, promoting the long-term growth of user satisfaction and the deep precipitation of brand loyalty.

Self-built multi-channel redundant channels ensure the verification code arrival rate remains stable above 95.2%.

Operational costs are reduced.

A leading digital banking platform manages assets of over 50 million users. In response to the increasingly rampant risk of financial account theft, the platform has built an intelligent risk control verification matrix in core transaction links. By deploying a dual protection mechanism of dynamic biometrics + SMS secondary verification, the interception rate of high-risk operations has been increased to 97.6%, while achieving a 500ms ultra-fast response to verification requests. It has constructed an invisible security shield at key business nodes, setting a new benchmark for the protection system of the digital finance industry.
