Connected healthcare technology platform Zus Health announced a $33M Series B financing round, bringing its total venture capital raised to more than $100M.

The financing round was led by Drive Capital , with participation from new investors Sanofi Ventures , HealthX Ventures , and Alumni Ventures , alongside existing backers Andreessen Horowitz (a16z) , F-Prime , Maverick Ventures , and JAZZ Venture Partners .

Operating at massive clinical scale, Zus Health supported more than 110 million networked transactions in August 2026 alone, while its clinical intelligence engine generated 39 million evidence citations year-to-date.

Founded in 2021 by Jonathan Bush—the healthcare technology pioneer who previously co-founded and led ambulatory cloud EHR giant athenahealth— Zus Health is designed to eliminate the need for digital health builders and healthcare enterprises to construct and maintain bespoke data integration plumbing.

At the center of Zus’s ecosystem is a continuously updated longitudinal record supported by three integrated operational layers:

The Platform Layer (Zus Aggregated Profile): The foundation of the system is the Zus Aggregated Profile (ZAP), which normalizes fragmented demographic, diagnostic, and procedural data points across disparate sources into a single unified patient chart. Supported by embedded clinical intelligence, ZAP transforms unstructured records into actionable data elements accessible via standard interfaces.

The Network Layer (Nationwide Data Mesh): Rather than requiring health systems or digital health developers to negotiate separate interfaces with thousands of individual hospitals and clinics, Zus provides turnkey connectivity across national EHR query networks (such as CommonWell and Carequality), electronic pharmacy data feeds, admission-discharge-transfer (ADT) care event notifications, and commercial diagnostic laboratories.
