TLDR: Innovaccer, a leading healthcare AI company, has acquired Story Health, an AI-powered platform specializing in continuous digital specialty care. This acquisition aims to integrate AI agents and human coaches to augment care teams, automate routine tasks, and enhance patient engagement, building on Story Health’s proven success in reducing hospital readmissions and improving patient outcomes in cardiovascular care.
Innovaccer Inc., a prominent healthcare artificial intelligence (AI) company, announced on September 16, 2025, its acquisition of Story Health, a pioneering AI-powered, tech-enabled platform. This strategic move is set to transform specialty care from episodic to continuous, digital models, marking Innovaccer’s fourth significant acquisition in the past two years, following Humbi AI, Cured, and Pharmacy Quality Solutions.
Story Health, founded in 2020 by Google veterans Tom Stanis, Nikhil Roy, and Cardiologist Ashul Govil, MD, MBA, developed a vertically integrated cardiovascular care platform. This platform combines AI-driven clinical pathways, advanced medication workflows, and human-led coaching to provide continuous management for conditions like heart failure, hypertension, and Atrial Fibrillation (AFib). The company had previously secured $22.6 million in Series A funding in 2022.
The core of this acquisition is Innovaccer’s vision to pioneer ‘agentic care augmentation.’ This model involves AI agents assisting specialty care teams with routine, non-clinical tasks and maintaining continuous patient engagement between clinic visits. Health coaches will work alongside these AI agents, engaging directly with patients on symptoms, medication adherence, and monitoring data from remote devices, triggering timely interventions when necessary. This integrated approach aims to embed the model within existing electronic health record (EHR) systems and workflows, enabling health systems to significantly scale specialty care capacity, reduce hospitalizations, and improve patient adherence without increasing the burden on clinicians.
Story Health has already demonstrated impressive results. Health systems utilizing their platform reported a 30-day heart failure all-cause readmission rate of just 6.9%, substantially lower than the national average of 18.1%. Furthermore, these systems observed over 60% reductions in hospitalizations and a notable improvement in daily patient engagement and medication adherence.
Abhinav Shashank, cofounder and CEO of Innovaccer, emphasized the transformative potential, stating, “Healthcare doesn’t change through dashboards alone. 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.”
Tom Stanis, cofounder and CEO of Story Health, echoed this sentiment, adding, “When we built Story Health, we believed specialty care needed more than software, it needed an operating model. Most platforms stop at insights. Story Health goes all the way to action. Joining forces allows us to scale nationally and turn continuous, AI-assisted specialty care into the new normal.”
Dr. Kirk Garratt, Medical Director of the Center for Heart and Vascular Health and Chair of Cardiology at ChristianaCare, a Story Health customer, highlighted the practical benefits: “By extending care beyond the walls of our clinics and into the daily lives of our patients, we’ve seen improvements in medication adherence, fewer hospitalizations, and stronger engagement between visits… The integration with Innovaccer will allow us to scale this model further, empowering our teams to provide continuous, personalized care without adding to clinician burden. This is a critical step forward in making advanced, AI-enabled specialty care accessible to more patients in our community.”
