The investment accelerates Cosan’s expansion of its AI-enabled, human-led virtual care platform, which empowers providers to deliver proactive, compassionate, and personalized support to individuals living with chronic conditions in between office visits. The funding will advance Cosan’s ability to scale its multidisciplinary care teams, enhance AI-driven insights, and support practices seeking to improve outcomes while strengthening operational efficiency.

“We’re proud to deepen our partnership with Cosan,” said Katie Schmitz, Managing Partner at Ziegler Link-age Funds. “Cosan is demonstrating how AI can amplify the human touch—closing care gaps, strengthening relationships, and delivering outcomes that matter to patients and providers.”

Dr. Paul Berggreen, Chief Strategy Officer at The Specialty Alliance, added: “Cosan has been an exceptional partner for supporting our patients between visits. As we broaden our services across GI, urology, rheumatology, and radiation oncology, their chronic care management model remains an essential resource.”

Cosan currently serves more than 130,000 patients nationwide and enrolls 300 new patients each day, helping practices expand chronic care programs without sacrificing empathy or clinical quality. Its AI tools synthesize patient data, surface rising risks, streamline workflows, and personalize engagement while allowing clinicians to stay focused on meaningful patient interactions.

“Our mission is to help providers deliver compassionate, high-quality care beyond the office,” said David Hunt, CEO of Cosan. “AI allows us to extend the reach of care teams, not replace them. This investment strengthens our ability to deliver connected, timely, and personal care that improves lives.”

Cosan’s approach supports the healthcare industry’s shift toward proactive, value-based chronic disease management—bringing together advanced automation with real human connection.
