A Pittsburgh artificial intelligence startup emerging as a challenger to Microsoft’s clinical note taking business has raised $150 million, a rare mega deal in a funding lull. The startup, Abridge, also has an unlikely cheerleader: Paul Ricci, the former head of Nuance, the service from Microsoft it competes with.

Abridge sells an AI tool that rapidly transcribes and summarizes doctors’ conversations with patients in a hospital’s electronic health records software. The startup’s leaders and investors tell STAT they’re betting that their medical knowledge, agility, and willingness to co-develop features with customers makes it a more attractive long term option than Nuance, which Microsoft says is currently used by most U.S. hospitals.
