Client Success Manager, Partnerships

Ascertain is building AI agents to automate the administrative work that burdens care teams. We are in major health systems and large specialty groups, saving hundreds of staff hours every week.

Our backers include Northwell Health, New York’s largest health system, and Deerfield Management, a leading healthcare investment firm.

Together, we’re on a mission to restore time, trust, and focus to the people who keep healthcare running. Our work is urgent — not because of startup timelines, but because our customers rely on us to drive financial resilience and operational clarity in a system under strain.
