Kangai Weishi APP Files IPO Prospectus: China's Largest Vertical Oncology-focused Mutual Support and Digital Health Platform

Mobile healthcare benefits from a confluence of favorable factors, including market demand, national policy support, and capital market investment. In particular, as general practice and lightweight consultation apps have gradually matured, vertical sectors have also begun to rise rapidly. Among these, the “Kangai Weishi” (Cancer Guardian) APP—the earliest and largest mutual aid service platform dedicated to cancer prevention and treatment within the mobile health vertical—is one of the fastest-growing and most representative products.

China's Largest Mutual Aid Service Platform for Cancer Prevention and Treatment: One-Stop, Full-Course Care for Oncology Conditions

Driven by his family’s experience in battling cancer, Jiang Zuochen was inspired to create the Anti-Cancer Guardian app.

In 2014, the Kang'ai Weishi (Cancer Guardian) APP became one of the earliest niche platforms to secure financing, launching the first mobile application dedicated to oncology. Within half a month of its launch, the platform registered over 6,000 users, with a daily active user rate ranging from 40% to 60%.

With the ultimate goal of enhancing therapeutic efficacy, the Kang’ai Weishi (Cancer Guardian) APP has pioneered an online service platform integrating cancer science popularization, anti-cancer information, doctor-patient communication, patient-to-patient mutual aid, and resource sharing. On one hand, Kang’ai Weishi provides a platform connecting doctors and patients, addressing long-standing challenges such as difficulty and high costs in accessing medical care, uneven distribution of medical resources, and insufficient disease awareness among cancer patients. Furthermore, Kang’ai Weishi advocates the philosophy of “uniting against cancer and maintaining a positive outlook,” encouraging resource mutual aid within the cancer community to help patients avoid unnecessary detours, improve medical efficiency, extend survival rates, enhance quality of life, and ultimately achieve chronic disease management for cancer. Jiang Zuochen, CEO of Kang’ai Weishi, stated, “Our mission is to enable the cancer community to obtain the greatest assistance and most effective information with the least amount of time, effort, and money.”

In 2015, the user base surpassed 300,000, establishing Kangai Weishi APP as the leading star product in the oncology vertical sector. It has also become a “spiritual home” for cancer patients and healthcare providers, offering not only medical consultation and treatment-seeking services but also heartfelt support and sincere friendships among many patients and their families.

Pioneering the Exclusive “Small Town” Model: A Warm and Loving Home for Cancer Care

Cancer-Fighting Town: “Don’t Give Up, We Are Together”

This May, Kang’ai Weishi pioneered the launch of its “Small Town” model. The user interface has shifted from the cold and rigid design typical of traditional mobile health platforms to a warm and welcoming experience. Unlike conventional single-user–machine interactions, Kang’ai Weishi’s “Small Town” is a mobile health app that embodies warmth, human connection, and care, fostering a sense of family and community among users.
Functionally, it delivers the most authoritative and comprehensive “one-stop, end-to-end support for cancer care” in the oncology vertical. From the patient’s perspective, it enables pre-consultation services such as selecting appropriate physician resources; during-treatment services including peer-to-peer exchanges with fellow patients, access to additional medical resources, and psychological mutual support; and post-treatment services through online communication with physicians. On Anti-Cancer Town, patients can receive support from more than 300,000 oncologists, leading experts, cancer survivor advocates, fellow patients, volunteers, and others.

From the perspective of oncologists, the Kang Ai Wei Shi APP serves as a convenient “mobile follow-up assistant,” enabling systematic management of cancer patients, 24-hour doctor-patient communication, post-diagnosis follow-up, and rehabilitation management during fragmented time intervals.

As the earliest entrant into the oncology mobile health sector, the company’s executive team—comprising professionals with backgrounds in multinational pharmaceutical companies, oncologists, and PhDs in oncology—has secured Kang’ai Weishi (Cancer Guardian) APP a distinct advantage in accessing medical resources, attracting thousands of physicians to join. Jiang Zuochen, CEO of Kang’ai Weishi, stated, “We only onboard the most outstanding oncologists and experts.” Currently, 100% of the registered physicians on Kang’ai Weishi specialize in diagnosing and treating oncology-related diseases. Notably, unlike other platforms, more than 70% of its registered physicians are senior specialists and experts with over 15–20 years of experience in oncology care.

As the earliest mobile health platform to launch, Kangai Weishi (Cancer Fighter Guardian) is not only a bellwether and pioneer in the vertical field of oncology-focused mobile healthcare, but also holds a leading position in the oncology mobile health market, commanding significant authority and trust among cancer patients. Regarding future development, Jiang Zuochen, CEO of Kangai Weishi, stated that the company will remain true to its original mission of “serving patients” by providing more extensive, in-depth derivative services tailored to the treatment and rehabilitation of cancer patients. One thing remains unchanged: Kangai Weishi will continue to be a steadfast, empathetic, and trusted companion for patients and their families throughout their journey against cancer.
