Spring Rain Doctor Secures Strategic Investment from Sogou: A Pioneer in Internet Healthcare Meets a Tech Giant

One is a “major internet company.” Its input method product boasts 464 million daily active users. As part of Tencent’s ecosystem, Sogou Search has long maintained deep cooperation with WeChat, leveraging the traffic advantages of WeChat’s entry points. It remains the only search engine capable of indexing content from WeChat Official Accounts, giving it significant advantages in both traffic and user base. Sogou began its foray into internet healthcare in 2019, establishing two internet healthcare companies and obtaining an internet hospital license in Hainan Province.

Prior to receiving investment from Sogou, Spring Rain Doctor had undergone five rounds of financing. During the first peak period of development in China’s internet healthcare sector from 2014 to 2016, Spring Rain Doctor’s models, such as symptom self-assessment and online consultation, gained recognition from institutional investors and secured substantial funding. This enabled the company to expand rapidly, accumulate a large base of physician and patient resources, and subsequently launch its open consultation services.

Since its establishment, Spring Rain Doctor has pioneered multiple innovative healthcare service models, including online consultations, cloud hospitals, private physician services, an open platform, and an internet-based diagnosis and treatment platform. By leveraging maximum technological and business model innovation, it provides users with multi-layered, full-cycle services encompassing medical and health science popularization, online health consultations, post-discharge health guidance, and internet-based diagnosis and treatment.

Online consultations are the core business of Chunyu Doctor. After five years of accumulation, in 2016, Chunyu Doctor announced the full opening of its online consultation services, encompassing three modules: API integration, medical resources, and artificial intelligence. The API integration module is designed to connect various types of applications, with Chunyu Doctor distributing and allocating medical resources, while artificial intelligence is utilized to expand the supply of medical services.

At this time, Chunyu Yisheng had over 498,000 registered physicians and more than 92 million consumer-end users. However, the traffic dividend from mobile clients was waning, making it increasingly difficult to acquire new users through independent efforts. Chunyu Yisheng chose to open its consultation platform, a strategy that drives user traffic to itself while empowering third parties, thereby achieving a win-win outcome.

Since then, Chunyu Yisheng (Spring Rain Doctor) has begun to systematically deliver online consultation services, as exemplified by Pu’an Chunyu Cloud Hospital and Yinchuan Chunyu Internet Hospital. Yinchuan Chunyu Internet Hospital operates under a co-construction model in partnership with local medical institutions, providing services such as enhancing basic diagnostic and treatment capabilities, facilitating access to high-quality medical resources, and offering remote consultations for complex and refractory cases. Its fundamental objective is to establish an online platform for medical consultations and data accumulation, thereby enabling a tiered diagnosis and treatment system centered on family physicians and health management.

In September 2017, the “Yanda Hospital Internet Diagnosis and Treatment Platform,” jointly developed by Chunyu Yisheng (Spring Rain Doctor) and Hebei Yanda Hospital, was launched. This marked Chunyu Yisheng’s first in-depth collaboration with an offline physical hospital, initiating its strategic direction of empowering hospitals. Yanda Hospital is a non-profit, private, Grade 3A hospital that has established collaborations with renowned institutions such as Beijing Chaoyang Hospital and Beijing Tiantan Hospital.

Through Chunyu Doctor, Yanda Hospital can enhance its service capabilities, extend its service radius, and improve service efficiency and quality. By integrating online internet platforms with offline physical hospitals, the platform provides the public with an integrated medical service featuring a closed-loop online-to-offline model, following the issuance of various policies on internet hospitals by the National Health Commission.

Certainly, Spring Rain Doctor did not stop there; it sought to better reach patients. In May 2019, Spring Rain Doctor officially launched the “Health Kiosk.” It is supported by a robust middle-end platform, leveraging nine years of accumulated resources: online consultations with 610,000 doctors, appointment registration and referral services from offline physical hospitals such as Yanda Hospital, and intelligent follow-up questions assisted by the Spring Rain AI Medical Assistant Brain. On the front end, the kiosks can be rapidly deployed—within approximately 15 days—and placed in communities, residential complexes, and enterprises, providing users with services such as health data monitoring, medication guidance, health education, and online prescription issuance.

First, as an early-established internet healthcare enterprise, Spring Rain Doctor has 610,000 registered physicians, of whom 380,000 have undergone real-name verification and can engage in in-depth interactions with patients on the platform. Second, users demonstrate a strong willingness to pay for medical consultations, indicating that they generally achieve satisfactory consultation and diagnostic outcomes on the platform.

As the policy and technological environments mature, Chunyu Yisheng is evolving from a mobile doctor-patient connection platform into a digital healthcare service connectivity platform. Its business lines are gradually expanding to cover medical care, health management, pharmaceuticals, insurance, and big data, forming a user-centric, health-oriented, and data-linked service and industrial closed loop.

First, to ensure the credibility of its search results, Sogou Search launched the “Authoritative Interpretations by Tier-3A Hospital Physicians” feature. The majority of these interpretations are provided by leading medical experts from China’s top-tier (Tier-3A) hospitals, offering high levels of authority, professionalism, and reference value. Physician resources between Sogou and Chunyu Doctors are mutually accessible.

Fourth, Spring Rain Doctor can leverage Sogou to facilitate greater connectivity. On February 21, VCBeat hosted an online roundtable forum themed “Fighting the Epidemic: Insights into Internet Healthcare and Opportunities.” At the forum, Wang Yuxiao, CEO of Spring Rain Doctor, stated that “symbiosis, collaboration, integration, and growth” represent Spring Rain Doctor’s vision for the future trends of internet healthcare. As a major internet company, Sogou possesses inherent capabilities for connectivity.
