Based in Hong Kong, Cornerstone Robotics designs and manufactures advanced surgical robotic systems for hospitals and medical centers worldwide. The company develops the Sentire Surgical System, a fully in-house engineered platform featuring over 13,000 proprietary components to facilitate clinical applications across urology, general surgery, gynecology, and thoracic disciplines. Operating with a workforce of nearly 400 employees, the enterprise has successfully deployed its technology to complete over 300 surgical procedures at partner institutions including Prince of Wales Hospital and CUHK Medical Centre. After receiving regulatory approval from the National Medical Products Administration in China, the firm secured a $200 million Series D financing round in November 2025, following a $70 million Series C backed by institutional investors such as EQT, Qiming Venture Partners, and Alpha JWC Ventures. Cornerstone Robotics was founded in 2019 by Professor Samuel Au.
Cornerstone Robotics has raised $475.0M across 5 funding rounds.

Cornerstone Robotics is a private medical-technology company that develops endoscopic and soft-tissue surgical robots to make minimally invasive surgery more accessible and efficient worldwide.[1][4]
High-Level Overview
Cornerstone Robotics builds robotic surgical systems—principally the Sentire endoscopic surgical system—designed for delicate minimally invasive and soft-tissue procedures, and it sells these systems to hospitals, surgical centers, and clinical partners aiming to improve surgical precision and patient outcomes.[5][4] Founded as an R&D-led, vertically integrated medtech startup, the company positions itself on accessibility and scale: its stated mission is to deliver “accessible surgical systems” and high-quality care broadly, and it emphasizes internal R&D, multiple production facilities in the Greater Bay Area, and international clinical adoption to support commercialization.[1][5][4] Recent capital raises (including a multi-hundred‑million dollar financing round reported around Series C) have been used to accelerate commercialization, regulatory clearances, clinical studies, and global expansion—evidence of meaningful growth momentum and investor confidence.[4][1]
Origin Story
Cornerstone Robotics was founded in 2019 and spun out of academic research with links to The Chinese University of Hong Kong, establishing innovation hubs in Hong Kong, Shenzhen, Beijing, Shanghai, London and Portsmouth as it scaled.[1][2] The founding team assembled surgical-robotics experts and clinical professionals to pursue translation from laboratory prototypes to clinical systems; early milestones reported by the company include proof‑of‑concept and cadaver/animal testing in 2020 and porcine and human clinical testing beginning in 2021.[1] Early traction included clinical trials in Hong Kong, Mainland China and the UK, strategic partnerships with academic and healthcare institutions, and sizeable financing rounds to fund production and market entry.[1][4]
Core Differentiators
Role in the Broader Tech Landscape
Cornerstone Robotics is riding the broader trend toward surgical-robotics adoption and decentralization of minimally invasive care, where increasing regulatory approvals, greater surgeon familiarity with robotic tools, and demand for better patient outcomes drive market growth.[4][1] Timing is favorable because many health systems are investing in technologies that can reduce complications and length of stay while expanding access to advanced procedures outside a few high‑end centers; Cornerstone’s focus on accessibility and local manufacturing is aimed at capturing demand in Asia and beyond.[5][1] By pursuing both clinical validation and scaled production, the company contributes to ecosystem maturation—providing a commercially viable alternative to incumbent systems and fostering competition that can lower costs and broaden surgeon training opportunities.[4][1]
Quick Take & Future Outlook
Cornerstone Robotics appears positioned to move from R&D and early clinical deployment into broader commercial roll‑out, supported by recent funding and regulatory progress; near‑term objectives will likely include expanded CE/other regional clearances, scaling hospital installations, and adding surgical‑specialty pipelines beyond its first endoscopic system.[4][1] Key trends that will shape its path are cost‑sensitive adoption in emerging markets, the pace of reimbursement and hospital purchasing cycles, competitive responses from established surgical‑robotics vendors, and continued clinical outcomes data to prove value.[4][1] If Cornerstone can sustain clinical evidence, maintain supply‑chain scale, and secure regulatory clearances across target geographies, it could become a notable regional challenger in surgical robotics and help lower the barrier of entry for advanced minimally invasive procedures—fulfilling its stated mission of broader access to high‑quality surgical care.[1][4]
