It has been said that we don’t have “big data” in healthcare, but instead a large amount of “small data.”

In this episode, Halle speaks with Kyle Armbrester, CEO of Datavant and former CEO of Signify Health (acquired for $8B), about why healthcare data still moves the way it did decades ago and what it will take to modernize it at scale. Kyle reflects on building and leading large health tech companies and explains how fixing data flow could reduce administrative waste, improve security, and make care easier for patients and providers alike.

We cover:

Why healthcare billing still happens after the fact and how that fuels administrative waste
How missing data standards led to fax-based workflows and brittle systems
Why healthcare data is such an attractive target for cyberattacks
How clinical data can be shared digitally without being owned or resold
Leadership lessons from scaling companies through IPOs and acquisitions
