Heartflow, Inc. (the “Company”) was incorporated in the state of Delaware in July 2007.

The Company is a commercial-stage medical technology company that provides software and artificial intelligence (“AI”) designed to deliver a non-invasive solution for diagnosing and managing coronary artery disease (“CAD”). The Company’s novel Heartflow Platform uses AI and advanced computational fluid dynamics to create a personalized 3D model of a patient’s heart based on a single coronary computed tomography angiography (“CCTA”). This results in actionable data on blood flow, stenosis, plaque volume and plaque composition. The Company’s Heartflow FFRCT Analysis and Plaque Analysis software assists physicians in diagnosing, managing and delivering precision care to patients with CAD. The Company was awarded Conformité Européene Mark for its Heartflow FFRCT Analysis in July 2011. The Company received clearance from the U.S. Food and Drug Administration (“FDA”) in November 2014 for its Heartflow FFRCT Analysis and in October 2022 for its Plaque Analysis.

The Company’s headquarters is located in San Francisco, California, and the Company also has offices in Mountain View, Rohnert Park and Santa Rosa, California, Austin, Texas, and Tokyo, Japan.
