about us


Reimagine Acute and Chronic Care Management

We are a digital health solutions company based in Silicon Valley. We aim to delay or avoid disease progression across the population by helping manage acute and chronic conditions, while improving access to care and driving efficiencies in care delivery.

We apply digital technologies to augment clinical pathways – utilizing intelligent sensors, mobile app, machine-learning (“AI”), and blockchain technologies to connect, engage and empower the patient, and orchestrate care delivery by the ecosystem of providers.


Plethy for plenty – plenty of health, that is!

Plethy refers to an ancient Indo-European word that gave us plethora and plenty — denoting abundance. In medicine, plethysmograph is key to measuring volume changes (“fullness”) from circulation. We at Plethy aspire for an abundance of health and good Qi (“circulation”) for everyone.
