Innovaccer Inc., a San Francisco-based company that uses AI and analytics to help health systems with population health efforts, has acquired Story Health, a tech-enabled platform focused on transforming specialty care from episodic to continuous, digital models. 

The purchase, for an undisclosed sum, marks the company’s fourth acquisition in the past two years, the company said. The acquisition builds on previous acquisitions including Humbi AI, Cured, and Pharmacy Quality Solutions, extending its “Healthcare Intelligence Cloud” into agentic care augmentation.

Over the past years, Innovaccer says, it has built the foundations of a fully integrated healthcare operating system from data unification to patient engagement to pharmacy quality, actuarial intelligence and, now, agentic care augmentation.

Healthcare Innovation has covered Story Health’s partnerships with health systems, including Utah’s Intermountain Health and ChristianaChare in Delaware. 

In a February 2024 interview, Kirk Garratt, M.D., medical director of the Center for Heart & Vascular Health at ChristianaCare, and Story Health CEO Tom Stanis spoke about their collaboration to improve health outcomes for patients living with hypertension and heart failure in Wilmington, Del.

The partnership uses Story Health’s digital hybrid platform that provides patients with a dedicated health coach to ensure their care plan is followed and treatment goals are achieved. Through this approach, ChristianaCare said it has been able to address some health disparities, with a significant improvement in the number of Black patients adhering to prescribed doses of guideline-directed medical therapy for heart failure.

Stanis, a former Google and Verily Life Sciences executive, described three parts to what Story Health offers. They built a technology platform and care planning tool that integrates with the electronic health record to help clinicians plan care for patients beyond the clinic visit, including managing medications for patients. Clinicians can see the clinical data from the EHR merged with data from the patient’s home about how they're doing. 

The second part is focused on the patient experience to help guide them through all of this and remind them what they are supposed to be doing. “It works over SMS, over text-based communication with the patient so they don't need a fancy phone or anything like that,” Stanis said. 

The third part is a care extension team with health coaches. These are nurses and lower-licensure professionals who are there to help the patient with any barriers they run into. “That could be understanding what their instructions are or dealing with the fact that maybe they get to the pharmacy and find out their meds cost $900 and they don't know how to pay for that," Stanis said. "Or figuring out that they get labs drawn to see whether these meds are working. How am I going to do that?”

Unlike the urban environment of ChristianaCare’s patients, Story Health is working in a much more rural situation with Intermountain in six or seven states all across the West. “They’ve got wonderful centers of excellence in Salt Lake City, where they do amazing life-saving work, and then they have places that are far afield of that,” Stanis said. “It can be in the middle of nowhere in Utah, so they really need an option to be able to bring this kind of care to those patients who are not going to drive two or three hours to come to this center of excellence every time they need treatment.”


With Story Health, Innovaccer said it will pioneer agentic care augmentation, where AI agents assist specialty care teams with routine, non-clinical tasks and provide continuous patient engagement between visits. The company said health coaches, working alongside AI agents, can converse directly with patients about symptoms and medication adherence, monitor data from remote patient monitoring devices, and trigger timely interventions. By embedding this model into the EHR and existing workflows, Innovaccer is seeking to help health systems scale specialty care capacity, reduce hospitalizations, and improve adherence without increasing clinician burden.

Story Health will be soon target other specialties, including diabetes and COPD.

“Healthcare doesn’t change through dashboards alone,” said Abhinav Shashank, cofounder and CEO of Innovaccer, in a statement. “It changes when data and AI power completely new clinical models. Story Health has proven that in specialty care; and we’re excited to bring this technology and clinical expertise to our health system customers nationwide.”

Healthcare Innovation interviewed Shashank along with NAACOS CEO Emily Brower in May 2025.
