About Us

At Lilac, we believe that transforming healthcare requires bringing together talent as multifaceted and disparate as the challenges to be solved. That is why our founding team possesses a mosaic of skills, knowledge, experiences, and mindsets.

We are a team of technologists, Payer operators, entrepreneurs, and, above all, relentless builders and problem solvers. We strike a balance between embracing innovation and honoring healthcare’s mission with reverence. We care deeply about playing a role in improving our Healthcare system, but respect how important it is to find paths that minimize risk and disruption.

This founding DNA will shape how we build and scale Lilac. We believe that it’s crucial not only to our success, but also to the success of our customers and our ability to more broadly impact the healthcare system.

Lilac is now part of Medisolv 

In 2026, we joined Medisolv, combining our AI-powered predictive analytics with more than 25 years of healthcare quality expertise.

Together, we help healthcare organizations move beyond measurement to prediction and action, identifying patients at risk, closing care gaps sooner, improving quality outcomes, and succeeding in value-based care models.

As part of Medisolv, we are expanding what’s possible with healthcare quality data, bringing together predictive intelligence, clinical expertise, and proven quality improvement strategies to help organizations deliver safer, higher-quality, and more equitable care.
