Jonathan Bush’s health data startup Zus Health raises $40M

Zus Health, a health data platform led by digital health veteran Jonathan Bush, scooped up $40 million in financing.

The raise included participation from JAZZ Venture Partners, F-Prime Capital, Maverick Ventures and Andreessen Horowitz (a16z).


Zus offers a platform that aims to connect health information so that providers can access a single view of their patient’s history, including their coverage, care team and medications. The company plans to use the latest funding to add new data sources, build workflow and referral tools, and introduce integration pathways so providers can use external patient data.

“We have found a critically important role for Zus as the common information ground behind the many great electronic medical records, CRMs and patient care technologies that healthcare works with,” Zus CEO Bush said in a statement. “What has been long overdue is a vision of digestible, comprehensive patient information at the point of care, which Zus is uniquely situated to bring about.”

Alongside the funding, Zus announced a partnership with primary care tech company Elation Health, which provides tools for telehealth, patient engagement and an EHR geared toward primary care practices. Elation will integrate the Zus Aggregated Profile into its systems so clinicians can access patients records from hospitals, clinics, labs and pharmacies.

“The Zus partnership will drastically accelerate Elation’s ability to build out market-leading EHR solutions to support population health and value-based care initiatives,” Elation CEO and cofounder Kyna Fong said in a statement. “Together, Elation and Zus are optimizing how external health data is synthesized within the EHR platform, which will support many of our key goals, such as reducing clinician burden, strengthening the patient-physician relationship and driving primary care success.”


Founded in 2020, Zus announced a $34 million Series A in 2021. The company has since inked partnership deals with Healthie and Canvas Medical, which provide software and tech infrastructure for healthcare companies.

Bush is a veteran in health tech, founding digital health giant athenahealth in 1997. He resigned in 2018, following pressure from activist investor Elliott Management and allegations of sexual harassment. At the time, he also apologized for domestic violence that he said took place during his divorce in 2006. 

In 2019, Bush joined virtual primary care company Firefly Health as executive chairman. 

“I think the highest and best use of primary care is to earn the right to navigate, earn the right to quarterback care. There’s a lot of constraints on that. It means you’ve got to have the bandwidth and the connectivity to follow care,” he told MobiHealthNews in 2021.”A quarterback can’t throw the ball and not know where everyone is downfield. You got to see where everybody is. … To me, people who can do that best win.”
