As we enter the holiday season, we're reflecting on the people who make healthcare work: the care coordinators, the nurses, the teams who show up every day to ensure patients get the care they need. Their dedication, often under challenging circumstances, is what drives us. Thank you to our partners, customers, and the care teams within them. We're grateful to play a small part in giving you back time for the work that matters most. Wishing you and your families a restful, restorative Thanksgiving.

The results are in and they’re redefining what efficiency looks like in specialty care. We’re excited to announce our partnership with The Oncology Institute. Before Ascertain, The Oncology Institute’s 100+ clinics spent 350 hours every week on prior authorizations; manual faxes, portal logins, and endless follow-ups. In just 60 days, that time dropped by 95%, freeing up care coordinators to focus on what truly matters: helping patients start treatment without delay. This isn’t just time saved, it’s administrative transformation at scale, because when technology handles the complexity, people can focus on care.

Proud to partner with Northwell Health to turn the tide on clinician burnout. Ascertain’s AI platform handles the grunt work like documentation and prior authorizations. This frees up care teams to spend more time on what really matters – the patients. Thank you Jill Kalman, M.D. for your visionary leadership in making this collaboration a success. https://bit.ly/4kuMSiI #PatientJourney #CareCoordination #ReadmissionReduction #PostAcuteCare #LengthOfStay #HospitalEfficiency #PriorAuthorization

“I hope AI won't take my ability to have an original thought!” Mark Michalski’s not worried about that. “Our challenge - and our opportunity - is to ensure that these technologies empower us to think more deeply and originally, not less. I believe our creativity and critical thinking will set us apart. AI is here to enhance what we do, not replace the spark of originality that makes us human.” Mark is Chief Information Officer at Deerfield and the leader of our #DeerfieldIntelligence team. (Also, he’s hiring!) *Graphic created by ImageThink for Deerfield’s inaugural AI Forum.

Our vision at Ascertain has always been clear: build AI that makes healthcare worthy of the providers who deliver it and the patients who rely on it. Today that vision takes a major step forward. Deerfield Management has led our $10 million financing round, joined by Northwell Health. At the same time, I’m stepping into an additional role as Chief Information Officer at Deerfield, where I’ll launch a firm‑wide Software, Data & AI team. I'm honored to work with James Flynn and the rest of the incredible Deerfield team to scale the impact of AI across our firm, partners, and portfolio companies. For Ascertain, this round unlocks resources for faster product cycles and a deeper impact for hospital case‑management teams. The scale and strategic reach of Deerfield will be integral to making intelligent automation part of everyday care. I’m grateful to the Ascertain team for the late nights and weekends that brought us here, and to Deerfield and Northwell for believing in the mission. As for what's next: I’m looking for dedicated builders—software developers as well as data, AI, and ML engineers—to partner with. If you’re ready to build, let’s talk. Exciting journey ahead for both teams—now, back to work. #AI #Ascertain #Deerfield #Northwell #Hiring

We’re thrilled to share that Ascertain announced our Series A fundraise led by Deerfield Management with a strategic investment from Northwell Health. This achievement marks a significant milestone in our efforts to support health systems, payers, and independent provider groups in automating workflows and freeing up time to focus on quality patient care. Now more than ever, with case managers spending nearly 60% of their time on manual administrative tasks, we need to develop solutions that leverage AI to improve operational workflows. With the collaboration between Deerfield, Northwell, and Aegis Ventures, we’re well positioned to improve efficiency for healthcare workers and ultimately ensure patients receive the best care.
