A Decade of Dedication, Six Rounds of Investment Boost
Stand Firmly by Enterprises at Critical Moments
Ribo Life Science is the first biopharmaceutical project that marks Panlin Capital's transition from PE investment to VC investment.。
From Series A in 2015 to Series E2 in 2025,Panlin Capital has illustrated the essence of "Chinese-style patient capital" through a decade-long, precisely positioned six-round investment (A, B, C1, C+, E1, E2 rounds). As a result, Panlin Capital has become the external investment institution that has invested in Ribo Life Science the most times and is also one of the two institutions with the highest total investment amount.。
This long-term meticulous accompaniment aligns with the pulse of capital boosting enterprise development:
2015, Panlin Capital based on independent due diligence, in Ribo Life Science'sSeries AFirmly Betting in Financing; At that time, the first small nucleic acid drug Phase III clinical trial had failed, and large pharmaceutical companies such as Roche were exiting the field. The entire sector was just starting to recover from a low point, and the druggability of small nucleic acids remained unclear globally. Meanwhile, Panlin Capital was in the early stages of transitioning to venture capital (VC), having just built a professional VC investment team. It clarified its investment strategy: "Starting from demand, investing in innovative drug development enterprises for the prevention, diagnosis, and treatment of unmet major clinical diseases, as well as innovative medical device development enterprises," seeking "entrepreneurs among scientists." After receiving the project, Panlin Capital conducted independent due diligence and concluded that "delivery technology has made breakthroughs, and the future of small nucleic acid drugs looks promising," marking their first VC-stage investment in the biopharmaceutical field. In Panlin's view, small nucleic acid technology represents the "third wave" of modern pharmaceuticals following small molecules and antibody drugs. Its core advantage lies in targeting intracellular proteins that are difficult for traditional drugs to reach, precisely intervening at the mRNA level to address the root causes of diseases, theoretically holding the potential to meet numerous unmet clinical needs. More importantly, Liang Zicai, a scientist by background, demonstrated a strong willingness and ability to translate cutting-edge science into industrial applications, fitting the image of an "entrepreneur among scientists" as initially envisioned by Panlin Capital.
2017, Panlin Capital inSeries BContinued investment during financing has provided critical support for solidifying the core technology platform.
2019Is a critical turning point. At that time, although the investment enthusiasm for innovative drugs was rising, the market paid insufficient attention to true source innovation. Ribo Life Science was in the iteration period of its delivery technology platform, and the new generation platform had not yet fully taken shape. Against this backdrop, Panlin Capital provided the most crucial financial support to Ribo, decisively collaborating with 3E Bioventures.Led C1 Round, supporting its technological transformation. Trust also continues to deepen in the journey of development.
2021, Ribo Life Science completedC+ RoundInvestments from institutions such as Hillhouse Ventures and CICC have joined, the company's reputation and valuation have continued to rise, and Panlin Capital has remained committed to follow-up investments.
2022, Panlin Capital inE1 RoundThe additional investment in the financing round reflects confidence in Ribo Life Science's increasingly robust small nucleic acid delivery technology platform and clinical advancement of its product pipeline, as well as the initial formation of Ribo's global presence.
2025TheE2In this round of financing, Panlin Capital continued its support, assisting Ribo Life Science, which has established one of the world's largest siRNA drug pipelines, in making a final push towards the capital markets, until its successful IPO on the Hong Kong Stock Exchange. At this point, an innovative blueprint from scientists' laboratories to global capital markets is clearly revealed.
Behind this long-term companionship isPanlin Capital, driven by its long-term belief in the development of China's biopharmaceutical industry and based on a firm recognition of the founder, has never wavered regardless of the ups and downs of industry development or the favorable or adverse conditions of enterprise growth.。
As one of the serialized outcomes in Panlin Capital's VC investment portfolio, the investment practice in Ribo Life Science serves as one of the foundations for Panlin Capital's VC investment methodology. As of now,PPIO, a representative of the Panlin Multi-Round Investment, has submitted its listing application to the Hong Kong Stock Exchange. Subsequently, as multiple companies such as Yafei Biotech, Chuan Microelectronics, Woofly Aerospace, Ruiyun Cold Chain, ReNue Biotech, Goldschmidt Bio, Benyao Technology, Zhixin Haoteng, and Ebuy Industrial Products enter the IPO application process, the investment results of Panlin Capital's VC stage will gradually be validated.。
