Today I speak with A.G. Breitenstein, partner at Optum Ventures. She talks about what she looks for in health care businesses poised for success, and considers how they intersect with people. She says real people move markets, even markets as big as the one Optum currently occupies and occasionally completely dominates. I found it very interesting learning how Optum views the universe, at least the side of Optum concerned with potential future disruption.
