Elliott Green
Elliott Green is the co-founder and CEO of Dandelion Health, a New York-based real-world data and clinical AI platform building multimodal, longitudinal datasets from a consortium of non-academic health systems. A former founding member of Oscar Health with a finance background, Green launched Dandelion in 2020 to give life science companies and AI developers unbiased, clinical-grade data - including the images, waveforms, and notes that make up most of medicine but are rarely used. The company closed a $14M Series A in 2026 and has launched a free AI validation service and a GLP-1 data library aimed at bringing precision medicine to cardiometabolic disease.
Benjamine Liu
Benjamine Liu is the co-founder and CEO of Formation Bio, an AI-native pharmaceutical company in New York that licenses and develops its own drug pipeline. A Rhodes Scholar with a DPhil from Oxford, he started the company (originally TrialSpark) in 2016 after concluding during his graduate work that clinical trials, not discovery, were the real bottleneck slowing new treatments from reaching patients. Formation Bio has raised over $610 million, including a $372 million Series D led by a16z with backing from Sanofi.
