Emily Nieves

Emily Nieves is the co-founder and CEO of Delineate, a Cambridge, Massachusetts startup building AI agents that read the scientific literature the way a pharmacologist does - pulling numbers out of buried plots and patents to speed up drug development. A University of Georgia biological engineer turned MIT PhD researcher, she worked on computational modeling at Pfizer and AstraZeneca before deciding the bottleneck wasn't the models but the months it took to feed them. Delineate, part of Y Combinator's Winter 2025 batch, now works with top-10 pharma companies to turn months of systematic review into weeks.
