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.
As the Director/Manager of Partner Solutions, you will lead post-sale success and retention efforts for Ascertain’s most important partners. This role is ideal for someone with experience in healthcare technology, SaaS implementation, or healthcare consulting who’s ready to build a high-impact function from the ground up.
You will own end-to-end customer success after the initial sale: overseeing pilot delivery, driving change management and adoption, and ensuring long-term retention and expansion. You’ll work directly with care management and revenue cycle teams to make sure our platform integrates smoothly into their daily workflows, delivering real, measurable value.
You will manage end-to-end deployments, from initial implementations to ongoing customer success initiatives and onboarding for future products. You’ll partner closely with Sales, Product, Engineering, and Marketing to ensure each deployment delivers measurable impact, provides clear ROI metrics for go-to-market decisions, and sets the stage for seamless adoption of our offerings.
This is a hands-on, high-ownership role for an operator who thrives in ambiguity, leverages data to drive decisions, and is passionate about helping healthcare teams succeed. You’ll help define our partner success strategy, build scalable SOPs and playbooks, and shape the partner experience. Over time, you’ll have the opportunity to grow into a formal leadership role and build a team.
The insights you bring back from the field will directly shape how we build and sell, informing product priorities, go-to-market strategy, and how we define value for the customers we haven't won yet. This is one of the most strategically important roles at Ascertain.
This position will be based out of our office in New York City on a hybrid basis, but for the right candidate, we are open to remote work.
