Kazuki Shin is a machine learning engineer and entrepreneur based in San Francisco, California. He is the co-founder and chief technology officer of Kaigo Health, a health technology company that builds an AI-powered outpatient care workforce designed to help healthcare providers manage patient care outside of clinical settings, with a particular focus on older adults and Medicare patients.

Career

Prior to founding Kaigo Health, Shin worked at NVIDIA, where he contributed to autonomous vehicle perception technology. His work there involved augmented reality and virtual reality simulation as well as synthetic data generation, reportedly improving pedestrian detection accuracy by 24% and developing a self-improving data pipeline using domain adaptation techniques.

Shin studied at the University of Illinois Urbana-Champaign (UIUC), where he was affiliated with KIMLAB, a research laboratory. His academic work spanned areas related to machine learning and robotics.

Shin co-founded Kaigo Health to address inefficiencies in outpatient and post-discharge care. The company's platform automates clinical workflows that are typically performed manually by nursing staff, including patient follow-ups, check-ins, care gap identification and closure, claims auditing, and prior authorizations. According to the company, clinical staff often spend more than ten hours per month on preparatory tasks such as compiling patient chase lists and navigating between electronic health record systems before they can begin closing care gaps. Kaigo Health's AI tools are intended to reduce this administrative burden so that clinicians can focus on direct patient care.

The platform targets improvements in healthcare quality metrics including CAHPS and HCAHPS scores, as well as the capture of HCCs and CPT codes. The company positions its product as a means for healthcare organizations to close more care gaps without increasing headcount.

Kaigo Health participated in Y Combinator's Fall 2025 batch, one of eight startups in the cohort founded or co-founded by University of Illinois students or alumni. The company was among seven of those eight startups with co-founders from the Grainger College of Engineering.

The name "Kaigo" (介護) is a Japanese word meaning "care" or "nursing care," reflecting the company's focus on supporting the care of elderly populations.
