Zus Health Raises $33 Million Series B, Pushing Total Past $100 Million

Zus Health has raised $33 million in Series B funding, lifting its total capital to more than $100 million since its 2021 founding. Drive Capital led the round. Sanofi Ventures, HealthX Ventures, Alumni Ventures, Andreessen Horowitz, F-Prime, Maverick Ventures, and JAZZ Venture Partners also participated.

The company will spend the money on one problem: moving patient data. Zus builds infrastructure that combines fragmented clinical information into a continuously updated patient record. Its platform gives healthcare providers and applications access to complete patient information without each organization building its own connectivity network.

"The story of electronic medical records doesn't end with the silos we have today. We've spent decades digitizing healthcare, but the information still doesn't move with the patient. We're building a networked medical record that changes that—connecting information across the healthcare system and making it available to the people and applications that need it. And now, with AI, we have an extraordinary opportunity to build workflows that actually make delivering care easier, faster, and more effective," said Jonathan Bush, founder and chief executive officer of Zus Health.

How does the platform actually work?

The core product is the Zus Aggregated Profile. It builds a longitudinal patient record by pulling information from electronic health record networks, pharmacies, laboratories, care-event notifications, and other clinical sources. An intelligence layer then uses AI to organize that information and deliver it through clinical and administrative workflows.

The platform covers concrete use cases:

• Pre-visit preparation
• Care transitions
• Risk adjustment
• Quality-gap closure
• Population health management

Its Generated Patient Summaries compress fragmented records into concise information. Clinicians and care teams use those summaries during treatment.

What do the numbers show?

Scale is the company's main argument. Zus's national network supported more than 110 million transactions during August alone. Its AI-native clinical platform generated 39 million evidence citations during 2026 through the announcement date.

Zus has also applied to become a Qualified Health Information Network under the Trusted Exchange Framework and Common Agreement. Its candidacy and HITRUST certification back its push to join secure nationwide health information exchange.

For context, a hospital network stitching together records from dozens of EHR vendors typically negotiates separate data-sharing agreements with each one. Zus sells that connectivity as shared infrastructure, so each customer skips the buildout.

Why did Drive Capital write the check?

The investor thesis rests on connected data as the precondition for AI in healthcare. "We believe healthcare is entering a new era in which AI can fundamentally change how care is delivered, but that transformation depends on having reliable, connected patient information. Zus has built the foundation to address that challenge at scale. Its combination of technology, market opportunity, and leadership gives us conviction in the company's ability to help shape the next generation of healthcare," said Molly Bonakdarpour, general partner at Drive Capital.

The funding has four stated uses: improve clinical intelligence, expand national data connectivity, increase record freshness, and support additional workflows across value-based and specialty care.

What comes next?

The bet is that record freshness and workflow coverage decide who wins health data infrastructure. With QHIN candidacy pending, Zus is positioning itself inside the formal framework governing nationwide exchange rather than alongside it. The next test is whether 110 million monthly transactions grow into the network effect Bush is selling.
